2 - Semantic Guardrails

Implement AI-driven policies to protect sensitive data while allowing for flexible access controls.

Semantic Guardrails evaluates and mitigates risks in AI-generated content by scanning conversations for policy violations, sensitive data exposure, and off-topic responses. It enables organizations to enforce data protection policies, monitor data usage, and ensure compliance with regulatory requirements.

2.1 - Semantic Guardrails Architecture

Architecture of the Semantic Guardrails feature.

Protegrity’s GenAI Security Semantic Guardrails solution is a security guardrail engine for AI systems. It evaluates risks in GenAI chatbots, workflows, and agents through advanced semantic analytics and intent classification to detect potentially malicious messages. PII detection can also be leveraged for comprehensive security coverage.

The documentation here for Semantic Guardrails covers its specific requirements and relationship with AI Developer Edition. For more information, refer to the complete body of the Semantic Guardrails documentation.

Overview

Semantic Guardrails is trained on synthetic customer-service AI chatbot datasets. The system performs best when analyzing conversations expected to match the training domain, that is, English-language-based customer service interactions involving orders, tickets, and purchases.

For domain-specific and user-specific applications requiring high detection accuracy, fine-tuning is necessary to completely leverage the model’s ability. This helps the model to learn from expected conversation patterns and message structures in both the inputs and outputs of protected GenAI systems.

The system operates by analyzing conversations between participants. These participants are users and AI systems, such as LLMs, agents, or contextual information sources. Furthermore, the system utilizes Protegrity’s Data Discovery, if present in the same network environment, to leverage PII detection in its internal decision algorithm.

The solution provides individual message risk scores and classifications, and cumulative conversation risk scores and classifications. This dual-scoring approach ensures that while individual messages may appear benign, potentially risky cumulative conversation patterns are identified. This significantly enhances detection of sophisticated attack vectors, including LLM jailbreaks and prompt injection attempts.

Arguments:

  • endpoint - Base URL of the synthesis API.
  • model_version - Version identifier for model persistence.
  • config - Advanced client configuration.
  • storage_config - Artifact storage credentials/configuration.

```python
synth = RemoteTabularGAN(
    endpoint="http://localhost:8000",
    categorical_cols=["city", "product"],
    epochs=300,
)
synth.fit(df)
synthetic = synth.transform(n=1000)

config

Configuration for the Synthetic Data SDK

Manages client-side settings for API communication, including endpoint URLs, timeouts, retry policies, and authentication.


Supported Data URI Formats

Cloud data can be passed to any SDK method that accepts a str path. The server resolves URIs using pty-ai-artifact-storage-lib. Credentials are embedded directly in the URI, there is no separate storage_config field.

AWS S3

s3://bucket/path/to/file.csv # IAM / instance role s3://ACCESS_KEY:SECRET_KEY@REGION/bucket/prefix/ # explicit credentials s3://bucket/path?region=us-east-1&connect_timeout=5&read_timeout=600

Google Cloud Storage

gs://bucket/path/to/file.csv # Application Default Creds gs://project@/bucket/prefix/?credentials=/path/to/sa.json

Azure Blob Storage

azure://container/blob.csv # DefaultAzureCredential Connection string and account URL are server-side settings only

MinIO (S3-compatible)

minio://ACCESS_KEY:SECRET_KEY@HOST:PORT/bucket/prefix/ http://bucket.HOST:PORT/prefix # virtual-hosted style

Local filesystem (SDK reads client-side and sends inline)

  • file:///abs/path/to/file.csv
  • /abs/path/to/file.csv
  • ./relative/path.csv The SDK detects these, reads the file locally, and sends data as inline base64. The server never receives a local path.

Multi-table (dict of URIs or local paths)

Pass a dict[str, str] mapping table names to any of the URI formats above when using multi-table synthesizers. All tables must use the same input kind: either all local paths/file:// URIs (SDK reads and sends inline) or all cloud URIs (passed to the server). Mixing the two raises ValueError.

Timeout query parameters (all cloud backends)

ParameterDefaultRange
connect_timeout10 s1 – 300 s
read_timeout300 s1 – 3600 s

Examples:

```python
from synthetic_data_sdk import ClientConfig, RemoteVineCopula

# Custom configuration
config = ClientConfig(endpoint="http://api.example.com:8000", timeout=60, max_retries=3)

synth = RemoteVineCopula(config=config)

# Pass S3 URI with embedded credentials
synth.fit("s3://AKID:SECRET@us-east-1/my-bucket/train.csv")

# Pass GCS URI (uses Application Default Credentials)
synth.fit("gs://my-bucket/data/train.csv")

# Multi-table with MinIO
from synthetic_data_sdk import RemoteMultiTableVineCopula
mt = RemoteMultiTableVineCopula(
    endpoint="http://api.example.com:8000",
    relationships=[("customers", "id", "orders", "customer_id")],
)
mt.fit(
    {
        "customers": "minio://key:secret@minio.example.com:9000/bucket/customers.csv",
        "orders": "minio://key:secret@minio.example.com:9000/bucket/orders.csv",
    }
)
```

  4. Run the following command to remove the containers and images.

    docker compose down --rmi all
    

4 - Anonymization

Protect sensitive data by anonymizing it while maintaining its utility for analysis and development.

Anonymization is a powerful feature that helps organizations protect sensitive data by anonymizing it while maintaining its utility for analysis and development. By leveraging AI, Anonymization enables organizations to transform sensitive data into anonymized data that preserves its analytical value while ensuring privacy and compliance.

4.1 - Anonymization Architecture

Architecture of the Anonymization feature.

Protegrity Anonymization allows processing of the datasets through generalization, to ensure the risk of re-identification is within tolerable thresholds. The anonymization process will have an impact on data utility, but Protegrity Anonymization optimizes this fundamental privacy-utility trade-off to ensure maximum data quality within the privacy goals.

Protegrity Anonymization leverages Kubernetes for data anonymization at scale and it provides instructions and support for deployment and usage on AWS EKS and Microsoft Azure AKS.

An overview of the communication is shown in the following figure.

Anonymization Components

Architecture

Protegrity Anonymization uses several pods on Kubernetes. The Protegrity Anonymization Web Server processes requests and stores the data securely in an internal Database Server. The Protegrity Anonymization request is received by the Nginx-Ingress component. Ingress forwards the request to the Anon-App. The Anon-App processes the request and submits the tasks to the cluster. The scheduler schedules tasks on the workers. The Anon-app stores the metadata about the job in the Anon-DB container. Next, the workers read, write, and process the data that is stored in the Anon-Storage, the request stream, or the Cloud storage. The Anon-Storage uses S3 bucket for storing data. The communication between the scheduler and the workers is handled by the scheduler. The workers run on random ports.

The user accesses Protegrity Anonymization using HTTPS over port 443. The user requests are directed to an Ingress Controller, and the controller in turn communicates with the required pods using the following ports:

  • 8090: Ingress controller and the Protegrity Anonymization API Web Service
  • 8786: Ingress controller
  • 8100: Ingress controller and S3 bucket

Protegrity Anonymization leverages Kubernetes for data anonymization at scale and it provides instructions and support for deployment and usage on AWS EKS and Microsoft Azure AKS.

Components

Protegrity Anonymization is composed of the following main components:

  • Protegrity Anonymization REST Server: This core component exposes a REST interface through which clients can interact with the Protegrity Anonymization service. It uses an in-memory task queue and stores anonymized datasets and respective metadata on persistent storage. Protegrity Anonymization tasks are submitted to a queue and are handled in first-in first out fashion.

Note: Only one anonymization task is executed at a time in Protegrity Anonymization.

  • REST Client: The client connects to the Protegrity Anonymization REST Server using an API tool, such as Postman, to create, send, and receive the Protegrity Anonymization request. It also provides a Swagger interface detailing the APIs available. The Swagger interface can also be used as a REST client for raising API requests.
  • Python SDK: It is the Python programmatic interface used to communicate with the REST server.
  • Anon-Storage*: It is used to read data from and write data to the storage. It uses the S3 bucket framework to perform file operations.
  • Anon-DB: It is a PostgreSQL database that is used to store metadata related to Protegrity Anonymization jobs.

4.2 - Prerequisites for Anonymization

Understanding Users and Roles

The users and roles are built-in for impersonate testing. Leverage any of the preconfigured users to showcase Protegrity’s Role-Based Access Controls. Using a different user will result in distinct views over sensitive data. Some users will only be able to protect data but will not be able to reverse the operation. Some users will only be able to re-identify selected attributes.

To use any of the roles, simply pass the chosen value to the payload in the user attribute during the protect or unprotect operation. If the user is not specified, the request will default to superuser.

The following roles and users have been configured and are available for use:

RoleUserDescription
ADMINadmin, devops, jay.banerjeeThe role can protect all data but cannot unprotect. If this role attempts to unprotect, they will only see protected values.
FINANCEfinance, robin.goodwillThe role can unprotect all PII and PCI data. The role cannot protect any data. If this role attempts to unprotect data without authorization they will only see null values.
MARKETINGmarketing, merlin.ishidaThe role can unprotect some PII data that is required for analytical research and campaign outreach. When attempting to unprotect data without authorization, they will only see null values. The role cannot protect any data.

5.4 - Using the Application Protector Python APIs

The various APIs of the AP Python.

The various APIs supported by the AP Python are described in this section. It describes the syntax of the AP Python APIs and provides sample use cases.

Before running the APIs in this section, ensure that the required credentials are obtained and environment variables are specified, using the steps from Optional - Obtaining access to the AI Developer Edition API Service.

Initialize the protector

The Protector API returns the Protector object associated with the AP Python APIs. After instantiation, this object is used to create a session. The session object provides APIs to perform the protect, unprotect, or reprotect operations.

Protector(self)

Note: Do not pass the self parameter while invoking the API.

Parameters

None

Returns

Protector: Object associated with the AP Python APIs.

Exceptions

InitializationError: This exception is thrown if the protector fails to initialize.

Example

In the following example, the AP Python is initialized.

from appython import Protector
protector = Protector()

create_session

The create_session API creates a new session. The sessions that are created using this API automatically time out after the session timeout value has been reached. The default session timeout value is 15 minutes. However, you can also pass the session timeout value as a parameter to this API.

Note: If the session is invalid or has timed out, then the AP Python APIs that are invoked using this session object, may throw an InvalidSessionError exception. Application developers can catch the InvalidSessionError exception and create a session again by invoking the create_session API.

def create_session(self, policy_user, timeout=15)

Note: Do not pass the self parameter while invoking the API.

Parameters

policy_user: Username defined in the policy, as a string value.
timeout: Session timeout, specified in minutes. By default, the value of this parameter is set to 15. This parameter is optional.

Returns

session: Object of the Session class. A session object is required for calling the data protection operations, such as protect, unprotect, and reprotect.

Exceptions

ProtectorError: This exception is thrown if a null or empty value is passed as the policy_user parameter.

Example

In the following example, superuser is passed as the policy_user parameter.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")

get_version

The get_version API returns the version of the AP Python in use. Ensure that the version number of the AP Python matches with the AP Python build package.

Note: You do not need to create a session for invoking the get_version API.

def get_version(self)

Note: Do not pass the self parameter while invoking the API.

Parameters

None

Returns

String: Product version of the installed AP Python.

Exceptions

None

Example

In the following example, the current version of the installed AP Python is retrieved.

from appython import Protector
protector = Protector()
print(protector.get_version())

Result

1.1.1

protect

The protect API protects the data using tokenization, data type preserving encryption, No Encryption, or an encryption data element. It supports both single and bulk protection without a maximum bulk size limit. However, it is recommended not to pass more than 1 MB of input data for each protection call.

For String and Byte data types, the maximum length for tokenization is 4096 bytes, while no maximum length is defined for encryption.

def protect(self, data, de, **kwargs)

Note: Do not pass the self parameter while invoking the API.

Parameters

  • data: Data to be protected. You can provide the data of any type that is supported by the AP Python. For example, you can specify data of type string, or integer. However, you cannot provide the data of multiple data types at the same time in a bulk call.
  • de: String containing the data element name defined in policy.
  • kwargs: Specify one or more of the following keyword arguments:
    • external_iv: Specify the external initialization vector for Tokenization. This argument is optional.
    • encrypt_to: Specify this argument for encrypting the data and set its value to bytes. This argument is mandatory. It must not be used for Tokenization.
    • charset: This is an optional argument. It indicates the byte order of the input buffer. You can specify a value for this argument from the charset constants, such as UTF8, UTF16LE, or UTF16BE. The default value for the charset argument is UTF8.
      The charset argument is only applicable for the input data of byte type.
      The charset parameter is mandatory for the data elements created with Unicode Gen2 tokenization method for byte APIs. The encoding set for the charset parameter must match the encoding of the input data passed.

Note: Keyword arguments are case sensitive.

Returns

  • For single data: Returns the protected data
  • For bulk data: Returns a tuple of the following data:
    • List or tuple of the protected data
    • Tuple of error codes

Exceptions

InvalidSessionError: This exception is thrown if the session is invalid or has timed out.
ProtectError: This exception is thrown if the API is unable to protect the data.

Note: If the protect API is used with bulk data, then it does not throw any exception. Instead, it only returns an error code.
For more information about the return codes, refer to Log return codes for Protectors.

Example - Tokenizing String Data

The examples for using the protect API for tokenizing the string data are described in this section.

Example 1: Input string data
In the following example, the Protegrity1 string is used as the data, which is tokenized using the string Alpha Numeric data element.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("Protegrity1", "string")
print("Protected Data: %s" %output)

Result

Protected Data: 4l0z9SQrhtk

Example 2: Input string data using session as Context Manager
In the following example, the Protegrity1 string is used as the data, which is tokenized using the string Alpha Numeric data element.

from appython import Protector
protector = Protector()
with protector.create_session("superuser") as session:
    output = session.protect("Protegrity1", "string")
    print("Protected Data: %s" %output)

Result

Protected Data: 4l0z9SQrhtk

Example 3: Input date passed as a string
In the following example, the 1998/05/29 date string is used as the data, which is tokenized using the datetime Date data element.
If a date string is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date string in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("1998/05/29", "datetime")
print("Protected data: "+str(output))

Result

Protected data: 0634/01/28

Example 4: Input date and time passed as a string
In the following example, the 1998/05/29 10:54:47 datetime string is used as the data, which is tokenized using the datetime Datetime data element.
If a date and time string is provided as input, then the data element with the same tokenization type as the input format must be used for data protection. For example, if the input date and time string in YYYY/MM/DD HH:MM:SS MMM format is provided, then only the Datetime (YYYY-MM-DD HH:MM:SS MMM) data element must be used to protect the data.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("1998/05/29 10:54:47", "datetime")
print("Protected data: "+str(output))

Result

Protected data: 0634/01/28 10:54:47

Example 5: Unicode Input passed as a String

In the following example, the protegrity1234ÀÁÂÃÄÅÆÇÈÉ Unicode data is used as the input data, which is tokenized using the string data element.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect('protegrity1234ÀÁÂÃÄÅÆÇÈÉ', "string")
print("Protected Data: %s" %output)

Result

Protected Data: VSYaLoLxo8GMyqÀÁÂÃÄÅÆÇÈÉ

Example - Tokenizing String Data with External Initialization Vector (IV)

The example for using the protect API for tokenizing string data using external initialization vector (IV) is described in this section.

If you want to pass the external IV as a keyword argument to the protect API, then you must first pass the external IV as bytes to the API.

Example
In this example, the Protegrity1 string is used as the data tokenized using the string data element, with the help of the external IV 1234 passed as bytes.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("Protegrity1", "string", 
external_iv=bytes("1234", encoding="utf-8"))
print("Protected Data: %s" %output)

Result

Protected Data: oEquECC2JYb

Example - Encrypting String Data

The example for using the protect API for encrypting the string data is described in this section.

If you want to encrypt the data, then you must use bytes in the encrypt_to keyword.

To avoid data corruption, do not convert the encrypted bytes data into the string format. It is recommended to convert the encrypted bytes data to a Hexadecimal, Base 64, or any other appropriate format.

Example
In the following example, the Protegrity1 string is used as the data. This data is encrypted using the text data element, a generic placeholder for an encryption-capable element. Therefore, the encrypt_to parameter is passed as a keyword argument and its value is set to bytes.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("Protegrity1", "text", 
 encrypt_to=bytes)
print("Encrypted Data: %s" %output)

Result

Encrypted Data: b'\x84\x84\xaf\x10fwh\xd7w\x06)`"p\xe0V'

Example - Tokenizing Bulk String Data

An example for using the protect API for tokenizing bulk string data is described in this section. The bulk string data can be passed as a list or a tuple.

The individual elements of the list or tuple must be of the same data type.

Example 1: Input bulk string data
In the following example, protegrity1234, Protegrity1, and Protegrity56 strings are stored in a list and used as bulk data, which is tokenized using the string data element.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["protegrity1234", "Protegrity1", "Protegrity56"]
p_out = session.protect(data, "string")
print("Protected Data: ")
print(p_out)

Result

Protected Data: 
(['VSYaLoLxo8GMyq', '4l0z9SQrhtk', '9xP5wBuXJuce'], (6, 6, 6))

The success return code for the protect operation of each element on the list is 6.

Example 2: Input bulk string data
In Example 1, the protected output was a tuple of the tokenized data and the error list. This example shows how the code can be tweaked to ensure that the protected output and the error list are retrieved separately, and not as part of a tuple.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["protegrity1234", "Protegrity1", "Protegrity56"]
p_out, error_list = session.protect(data, "string")
print("Protected Data: ")
print(p_out)
print("Error List: ")
print(error_list)

Result

Protected Data: 
['VSYaLoLxo8GMyq', '4l0z9SQrhtk', '9xP5wBuXJuce']
Error List:
(6, 6, 6)

The success return code for the protect operation of each element on the list is 6.

Example 3: Input date passed as bulk strings
In the following example, the 2019/02/14 and 2018/03/11 strings are stored in a list and used as bulk data, which is tokenized using the datetime Date data element.

If a date string is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date string in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["2019/02/14", "2018/03/11"]
output = session.protect(data, "datetime")
print("Protected data: "+str(output))

Result

Protected data: (['1072/07/29', '0907/12/30'], (6, 6))

The success return code for the protect operation of each element on the list is 6.

Example 4: Input date and time passed as bulk strings
In the following example, the 2019/02/14 10:54:47 and 2019/11/03 11:01:32 strings are used as the data, which is tokenized using the datetime Datetime data element.

If a date and time string is provided as input, then the data element with the same tokenization type as the input format must be used for data protection. For example, if you have provided the input date and time string in YYYY/MM/DD HH:MM:SS MMM format, then you must use only the Datetime (YYYY-MM-DD HH:MM:SS MMM) data element to protect the data.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["2019/02/14 10:54:47", "2019/11/03 11:01:32"]
output = session.protect(data, "datetime")
print("Protected data: "+str(output))

Result

Protected data: (['1072/07/29 10:54:47', '2249/12/17 11:01:32'], (6, 6))

The success return code for the protect operation of each element on the list is 6.

Example - Tokenizing Bulk Bytes Data with External IV

An example for using the protect API for tokenizing bulk bytes data using external IV is described in this section. The bulk bytes data can be passed as a list or a tuple.
The individual elements of the list or tuple must be of the same data type.

Example
In the following example, protegrity1234, Protegrity1, and Protegrity56 strings are first converted to bytes using the Python bytes() method. The converted bytes are then stored in a list and used as bulk data. This bulk data is tokenized using the string data element, with the help of external IV 1234 that is passed as bytes.

Example - Encrypting Bulk Bytes Data

The example for using the protect API for encrypting bulk bytes data is described in this section. The bulk bytes data can be passed as a list or a tuple.

The individual elements of the list or tuple must be of the same data type.

To avoid data corruption, do not convert the encrypted bytes data into string format. It is recommended to convert the encrypted bytes data to a Hexadecimal, Base 64, or any other appropriate format.

Example
In the following example, protegrity1234, Protegrity1, and Protegrity56 strings are first converted to bytes using the Python bytes() method. The converted bytes are then stored in a list and used as bulk data, which is encrypted using the text data element. Therefore, the encrypt_to parameter is passed as a keyword argument and its value is set to bytes.

Example - Tokenizing Date Objects

The examples for using the protect API for tokenizing the date objects are described in this section.

If a date string is provided as input, then the data element with the same tokenization type as the input format must be used for data protection. For example, if you have provided the input date object in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

Example : Input date object in YYYY/MM/DD format
In the following example, the 1998/05/29 date string is used as the data. This is first converted to a date object using the Python date method of the datetime module.
The date object is then tokenized using the datetime data element.

from appython import Protector
from datetime import datetime
protector = Protector()
session = protector.create_session("superuser")
data = datetime.strptime("1998/05/29", "%Y/%m/%d").date()
print("\nInput date as a Date object : "+str(data))
p_out = session.protect(data, "datetime")
print("Protected date: "+str(p_out))

Result

Input date as a Date object : 1998-05-29
Protected date: 0634-01-28

Example - Tokenizing Bulk Date Objects

The example for using the protect API for tokenizing bulk date objects is described in this section. The bulk date objects can be passed as a list or a tuple.

The individual elements of the list or tuple must be of the same data type.

If a date object is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date object in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

Example: Input as a Date Object
In the following example, the 2019/02/12 and 2018/01/11 date strings are used as the data. These are first converted to date objects using the Python date method of the datetime module. The two date objects are then used to create a list, which is used as the input data.
The input list is then tokenized using the datetime data element.

from appython import Protector
from datetime import datetime
protector = Protector()
session = protector.create_session("superuser")
data1 = datetime.strptime("2019/02/12", "%Y/%m/%d").date()
data2 = datetime.strptime("2018/01/11", "%Y/%m/%d").date()
data = [data1, data2]
print("Input data: ", str(data))
p_out = session.protect(data, "datetime")
print("Protected data: "+str(p_out))

Result

Input data:  [datetime.date(2019, 2, 12), datetime.date(2018, 1, 11)]
Protected data: ([datetime.date(1154, 10, 29), datetime.date(1543, 1, 5)], (6, 6))

The success return code for the protect operation of each element on the list is 6.

unprotect

This function returns the data in its original form.

def unprotect(self, data, de, **kwargs)

Note: Do not pass the self parameter while invoking the API.

Parameters

  • data: Data to be unprotected.
  • de: String containing the data element name defined in policy.
  • kwargs: Specify one or more of the following keyword arguments:
    • external_iv: Specify the external initialization vector for Tokenization. This argument is optional.
    • decrypt_to: Specify this argument for decrypting the data and set its value to the data type of the original data. For example, if you are unprotecting string data, then you must specify the output data type as str. This argument is mandatory. This argument must not be used for Tokenization. The possible values for the decrypt_to argument are:
      • str
      • int
      • bytes
    • charset: This is an optional argument. It indicates the byte order of the input buffer. You can specify a value for this argument from the charset constants, such as UTF8, UTF16LE, or UTF16BE. The default value for the charset argument is UTF8.
      The charset argument is only applicable for the input data of byte type.
      The charset parameter is mandatory for the data elements created with Unicode Gen2 tokenization method for byte APIs. The encoding set for the charset parameter must match the encoding of the input data passed.

Note: Keyword arguments are case-sensitive.

Returns

  • For single data: Returns the unprotected data
  • For bulk data: Returns a tuple of the following data:
    • List or tuple of the unprotected data
    • Tuple of error codes

Exceptions

InvalidSessionError: This exception is thrown if the session is invalid or has timed out.
ProtectError: This exception is thrown if the API is unable to protect the data.

Note: If the unprotect API is used with bulk data, then it does not throw any exception. Instead, it only returns an error code.
For more information about the return codes, refer to Log return codes for Protectors.

Example - Detokenizing Bulk Integer Data

The example for using the unprotect API for retrieving the original bulk integer data from token data is described in this section.

The AP Python APIs support integer values only between -2147483648 and 2147483648, both inclusive.

Example
In the following example, 21, 42, and 55 integers are stored in a list and used as bulk data, which is tokenized using the int data element. The bulk integer data is then detokenized using the same data element.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = [21, 42, 55]
p_out = session.protect(data, "int")
print("Protected Data: ")
print(p_out)
out = session.unprotect(p_out[0], "int")
print("Unprotected Data: ")
print(out)

Result

Protected Data: 
([-94623223, -572010955, 2021989009], (6, 6, 6))
Unprotected Data: 
([21, 42, 55], (8, 8, 8))
  • The success return code for the protect operation of each element on the list is 6.
  • The success return code for the unprotect operation of each element on the list is 8.

Example - Detokenizing Bulk Integer Data with External IV

The example for using the unprotect API for retrieving the original bulk integer data from token data using external IV is described in this section.

If you want to pass the external IV as a keyword argument to the unprotect API, then you must pass the external IV as bytes to the API.

Example
In this example, 21, 42, and 55 integers are stored in a list and used as bulk data. This bulk data is tokenized using the int data element, with the help of external IV 1234 that is passed as bytes. The bulk integer data is then detokenized using the same data element and external IV.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = [21, 42, 55]
p_out = session.protect(data, "int", external_iv=bytes("1234", encoding="utf-8"))
print("Protected Data: ")
print(p_out)
out = session.unprotect(p_out[0], "int", external_iv=bytes("1234",  encoding="utf-8"))
print("Unprotected Data: ")
print(out)

Result

Protected Data: 
([1983567415, -1471024670, 1465229692], (6, 6, 6))
Unprotected Data: 
([21, 42, 55], (8, 8, 8))
  • The success return code for the protect operation of each element on the list is 6.
  • The success return code for the unprotect operation of each element on the list is 8.

Example - Decrypting Bulk Integer Data

The example for using the unprotect API for decrypting bulk integer data is described in this section.

If you want to decrypt the data, then you must use bytes in the decrypt_to keyword.

Example
In the following example, 21, 42, and 55 integers are stored in a list and used as bulk data, which is encrypted using the text data element. The bulk integer data is then decrypted using the same data element. Therefore, the decrypt_to parameter is passed as a keyword argument and its value is set to int.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = [21, 42, 55]
p_out = session.protect(data, "text", encrypt_to=bytes)
print("Encrypted Data: ")
print(p_out)
out = session.unprotect(p_out[0], "text", decrypt_to=int)
print("Decrypted Data: ")
print(out)

Result

Example - Detokenizing Date Objects

The example for using the unprotect API for retrieving the original data objects from token data is described in this section.

If a date object is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date object in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

Example 1: Input date object in MM.DD.YYYY format

In this example, the 2019/12/02 date string is used as the data, which is first converted to a date object using the Python date method of the datetime module.
The date object is then tokenized using the datetime data element and then detokenized using the same data element.

from appython import Protector
from datetime import datetime
protector = Protector()
session = protector.create_session("superuser")
data = datetime.strptime("2019/12/02", "%Y/%m/%d").date()
print("\nInput date as a Date object : "+str(data))
p_out = session.protect(data, "datetime")
print("Protected date: "+str(p_out))
unprotected_output = session.unprotect(p_out, "datetime")
print("Unprotected date: "+str(unprotected_output))

Result

Input date as a Date object : 2019-12-02
Protected date: 2936-03-31
Unprotected date: 2019-12-02

Example 2: Input date object in YYYY-MM-DD format

In this example, the 2019/02/12 date string is used as the data, which is first converted to a date object using the Python date method of the datetime module.
The date object is then tokenized using the datetime data element and then detokenized using the same data element.

from appython import Protector
from datetime import datetime
protector = Protector()
session = protector.create_session("superuser")
data = datetime.strptime("2019/02/12", "%Y/%m/%d").date()
print("\nInput date as a Date object : "+str(data))
p_out = session.protect(data, "datetime")
print("Protected date: "+str(p_out))
unprotected_output = session.unprotect(p_out, "datetime")
print("Unprotected date: "+str(unprotected_output))

Result

Protected date: 1154-10-29
Unprotected date: 2019-02-12

Example - Detokenizing Bulk Date Objects

The example for using the unprotect API for retrieving the original bulk date objects from the token data is described in this section.

If a date object is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date object in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

Example: Input as a Date Object
In this example, the 2019/02/12 and 2018/01/11 date strings are used as the data. These are first converted to date objects using the Python date method of the datetime module. The two date objects are then used to create a list, which is used as the input data.
The input list is then tokenized using the datetime data element and then detokenized using the same data element.

from appython import Protector
from datetime import datetime
protector = Protector()
session = protector.create_session("superuser")
data1 = datetime.strptime("2019/02/12", "%Y/%m/%d").date()
data2 = datetime.strptime("2018/01/11", "%Y/%m/%d").date()
data = [data1, data2]
print("Input data: "+str(data))
p_out = session.protect(data, "datetime")
print("Protected data: "+str(p_out))
unprotected_output = session.unprotect(p_out[0], "datetime")
print("Unprotected date: "+str(unprotected_output))

Result

  • The success return code for the protect operation of each element on the list is 6.
  • The success return code for the unprotect operation of each element on the list is 8.

reprotect

The reprotect API reprotects data using tokenization, data type preserving encryption, No Encryption, or an encryption data element. The protected data is first unprotected and then protected again with a new data element. It supports bulk protection without a maximum data limit. However, it is recommended not to pass more than 1 MB of input data for each protection call.

For String and Byte data types, the maximum length for tokenization is 4096 bytes, while no maximum length is defined for encryption.

Note: If you are retokenizing the data using the reprotect API, then the old data element and the new data element must have the same tokenization type. For example, if you have used Alpha-Numeric data element to protect the data, then you must use only Alpha-Numeric data element to reprotect the data.

def reprotect(self, data, old_de, new_de, **kwargs)

Note: Do not pass the self parameter while invoking the API.

Parameters

  • data: Protected data to be reprotected. The data is first unprotected with the old data element and then protected with the new data element.

  • old_de: String containing the data element name defined in the policy for the input data. This data element is used to unprotect the protected data as part of the reprotect operation.

  • new_de: String containing the data element name defined in the policy to create the output data. This data element is used to protect the data as part of the reprotect operation.

  • kwargs: Specify one or more of the following keyword arguments:

    • old_external_iv: Specify the old external IV in bytes for Tokenization. This old external IV is used to unprotect the protected data as part of the reprotect operation. This argument is optional.
    • new_external_iv: Specify the new external IV in bytes for Tokenization. This new external IV is used to protect the data as part of the reprotect operation. This argument is optional.
    • encrypt_to: Specify this argument for re-encrypting the bytes data and set its value to bytes. This argument is mandatory. This argument must not be used for Tokenization.
    • charset: This is an optional argument. It indicates the byte order of the input buffer. You can specify a value for this argument from the charset constants, such as UTF8, UTF16LE, or UTF16BE. The default value for the charset argument is UTF8.
      The charset argument is only applicable for the input data of byte type.
      The charset parameter is mandatory for the data elements created with Unicode Gen2 tokenization method for byte APIs. The encoding set for the charset parameter must match the encoding of the input data passed.

    Note: Keyword arguments are case-sensitive.

Returns

  • For single data: Returns the reprotected data
  • For bulk data: Returns a tuple of the following data:
    • List or tuple of the reprotected data
    • Tuple of error codes

Exceptions

InvalidSessionError: This exception is thrown if the session is invalid or has timed out.
ProtectError: This exception is thrown if the API is unable to protect the data.

Note: If the reprotect API is used with bulk data, then it does not throw any exception. Instead, it only returns an error code.
For more information about the return codes, refer to Log return codes for Protectors.

Example - Retokenizing String Data

The examples for using the reprotect API for retokenizing string data are described in this section.

If you are retokenizing the data using the reprotect API, then the old data element and the new data element must have the same tokenization type. For example, if you have used the Alpha-Numeric data element to protect the data, then you must use only the Alpha-Numeric data element to reprotect the data.

Example 1: Input string data
In the following example, the Protegrity1 string is used as the input data, which is first tokenized using the string data element.
The tokenized input data, the old data element string, and a new data element string are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("Protegrity1", "string")
print("Protected Data: %s" %output)
r_out = session.reprotect(output, "string", "address")
print("Reprotected Data: %s" %r_out)

Result

Protected Data: 4l0z9SQrhtk
Reprotected Data: hFReRmrqzzB

Example 2: Input date passed as a string
In the following example, the 2019/02/14 date string is used as the input data, which is first tokenized using the datetime data element.
If a date string is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date string in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.
The tokenized input data, the old data element datetime, and a new data element datetime are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("2019/02/14", "datetime")
print("Protected data: "+str(output))
r_out = session.reprotect(output, "datetime", "datetime_yc")
print("Reprotected data: "+str(r_out))

Result

Protected data: 1072/07/29
Reprotected data: 2019/07/13

Example 3: Input date and time passed as a string
In the following example, the 2019/02/14 10:54:47 datetime string is used as the input data, which is first tokenized using the datetime data element.
If a date and time string is provided as input, then the data element with the same tokenization type as the input format must be used for data protection. For example, if the input date and time string in YYYY/MM/DD HH:MM:SS MMM format is provided, then only the Datetime (YYYY-MM-DD HH:MM:SS MMM) data element must be used to protect the data. The tokenized input data, the old data element datetime, and a new data element datetime are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
output = session.protect("2019/02/14 10:54:47", "datetime")
print("Protected data: "+str(output))
r_out = session.reprotect(output, "datetime", "datetime_yc")
print("Reprotected data: "+str(r_out))

Result

Protected data: 1072/07/29 10:54:47

Example - Retokenizing String Data with External IV

The example for using the reprotect API for retokenizing string data using external IV is described in this section.

If you are retokenizing the data using the reprotect API, then the old data element and the new data element must have the same tokenization type. For example, if you have used the Alpha-Numeric data element to protect the data, then you must use only the Alpha-Numeric data element to reprotect the data.

If you want to pass the external IV as a keyword argument to the reprotect API, then you must pass the external IV as bytes to the API.

Example
In the following example, the Protegrity1 string is used as the input data. It is first tokenized using the string data element, with the help of external IV 1234 that is passed as bytes.
The tokenized input data, the string data element, the old external IV 1234 in bytes, and a new external IV 123456 in bytes are then passed as inputs to the reprotect API. As part of a single reprotect operation, the reprotect API first detokenizes the protected input data using the given data element and old external IV. It then retokenizes the data using the same data element, but with the new external IV.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
p_out = session.protect("Protegrity1", "string", 
 external_iv=bytes("1234", encoding="utf-8"))
print("Protected Data: %s" %p_out)
r_out = session.reprotect(p_out, "string", 
 "string", old_external_iv=bytes("1234", encoding="utf-8"), 
 new_external_iv=bytes("123456", encoding="utf-8"))
print("Reprotected Data: %s" %r_out)

Example - Retokenizing Bulk String Data

The examples for using the reprotect API for retokenizing bulk string data are described in this section. The bulk string data can be passed as a list or a tuple.

The individual elements of the list or tuple must be of the same data type.

If you are retokenizing the data using the reprotect API, then the old data element and the new data element must have the same tokenization type. For example, if you have used the Alpha-Numeric data element to protect the data, then you must use only the Alpha-Numeric data element to reprotect the data.

Example 1: Input bulk string data
In the following example, protegrity1234, Protegrity1, and Protegrity56 strings are stored in a list and used as bulk data, which is tokenized using the string data element.
The tokenized input data, the old data element string, and a new data element string are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["protegrity1234", "Protegrity1", "Protegrity56"]
p_out = session.protect(data, "string")
print("Protected Data: ")
print(p_out)
r_out = session.reprotect(p_out[0], "string", "address")
print("Reprotected Data: ")
print(r_out)

Result

Protected Data:

Reprotected Data: 
(['sOcSzhEwXTrclw', 'hFReRmrqzzB', 'imoJL6U4mWPk'], (50, 50, 50))

The success return code for the protect operation of each element on the list is 6.

Example 2: Input date passed as bulk strings
In the following example, the 2019/02/14 and 2018/03/11 strings are stored in a list and used as bulk data, which is tokenized using the datetime data element.

If a date string is provided as input, then the data element with the same tokenization type as the input date format must be used to protect the data. For example, if you have provided the input date string in YYYY/MM/DD format, then you must use only the Date (YYYY/MM/DD) data element to protect the data.

The tokenized input data, the old data element datetime, and a new data element datetime are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["2019/02/14", "2018/03/11"]
output = session.protect(data, "datetime")
print("Protected data: "+str(output))
r_out = session.reprotect(output[0], "datetime", "datetime_yc")
print("Reprotected data: "+str(r_out))

Result

Protected data: (['1072/07/29', '0907/12/30'], (6, 6))
Reprotected data: (['2019/07/13', '2018/12/14'], (50, 50))
  • The success return code for the protect operation of each element on the list is 6.
  • The success return code for the reprotect operation of each element on the list is 50.

Example 3: Input date and time passed as bulk strings
In the following example, the 2019/02/14 10:54:47 and 2019/11/03 11:01:32 strings are used as the data, which is tokenized using the datetime Datetime data element.
If a date and time string is provided as input, then the data element with the same tokenization type as the input format must be used for data protection. For example, if you have provided the input date and time string in YYYY-MM-DD HH:MM:SS MMM format, then you must use only the Datetime (YYYY-MM-DD HH:MM:SS MMM) data element to protect the data.
The tokenized input data, the old data element datetime, and a new data element datetime are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["2019/02/14 10:54:47", "2019/11/03 11:01:32"]
output = session.protect(data, "datetime")
print("Protected data: "+str(output))
r_out = session.reprotect(output[0], "datetime", "datetime_yc")
print("Reprotected data: "+str(r_out))

Result

Protected data: (['1072/07/29 10:54:47', '2249/12/17 11:01:32'], (6, 6))
Reprotected data: (['2019/07/13 10:54:47', '2019/05/29 11:01:32'], (50, 50))

The success return code for the protect operation of each element on the list is 6.

Example - Retokenizing Bulk String Data with External IV

The example for using the reprotect API for retokenizing bulk string data using external IV is described in this section. The bulk string data can be passed as a list or a tuple.

The individual elements of the list or tuple must be of the same data type.

If you are retokenizing the data using the reprotect API, then the old data element and the new data element must have the same tokenization type. For example, if you have used the Alpha-Numeric data element to protect the data, then you must use only the Alpha-Numeric data element to reprotect the data.

If you want to pass the external IV as a keyword argument to the reprotect API, then you must pass the external IV as bytes to the API.

Example
In the following example, protegrity1234, Protegrity1, and Protegrity56 strings are stored in a list. It is used as bulk data, which is tokenized using the string data element, with the help of external IV 123 that is passed as bytes.
The tokenized input data, the string data element and the old external IV 1234 in bytes are prepared. These along with a new external IV 123456 in bytes are then passed as inputs to the reprotect API. As part of a single reprotect operation, the reprotect API first detokenizes the protected input data using the given data element and old external IV. Then it retokenizes the data using the same data element, but with the new external IV.

from appython import Protector
protector = Protector()
session = protector.create_session("superuser")
data = ["protegrity1234", "Protegrity1", "Protegrity56"]
p_out = session.protect(data, "string",
 external_iv=bytes("1234", encoding="utf-8"))
print("Protected Data: ")
print(p_out)
r_out = session.reprotect(p_out[0], "string","string",
 old_external_iv=bytes("1234", encoding="utf-8"),
new_external_iv=bytes("123456", encoding="utf-8"))
print("Reprotected Data: ")
print(r_out)

Result

Protected Data: 
(['aCzyqwijkSDqiG', 'oEquECC2JYb', 't0Ly7KYx7Wyo'], (6, 6, 6))
Reprotected Data: 
(['EqDxRW2QhMqZJV', 'm6AROToSQ71', 'DTWuFfYK2ZpL'], (50, 50, 50))

The success return code for the protect operation of each element on the list is 6.

Example - Retokenizing Date Objects

The example for using the reprotect API for retokenizing date objects is described in this section.

If you are retokenizing the data using the reprotect API, then the old data element and the new data element must have the same tokenization type. For example, if you have used the Date (YYYY/MM/DD) data element to protect the data, then you must use only the Date (YYYY/MM/DD) data element to reprotect the data.

Example: Input as a data object
In the following example, the 2019/02/12 date string is used as the data, which is first converted to a date object using the Python date method of the datetime module. The date object is then tokenized using the datetime data element.
The tokenized input data, the old data element datetime, and a new data element datetime are then passed as inputs to the reprotect API. The reprotect API detokenizes the protected input data using the old data element and then retokenizes it using the new data element, as part of a single reprotect operation.

from appython import Protector
from datetime import datetime
protector = Protector()
session = protector.create_session("superuser")
data = datetime.strptime("2019/02/12", "%Y/%m/%d").date()
print("Input date as a Date object : "+str(data))
p_out = session.protect(data, "datetime")
print("Protected date: "+str(p_out))

5.5 - Using the Application Protector Java APIs

The various APIs of the AP Java.

The various APIs supported by the AP Java are described in this section. It describes the syntax of the AP Java APIs and provides sample use cases.

Before running the APIs in this section, ensure that the required credentials are obtained and environment variables specified, using the steps from Optional - Obtaining access to the AI Developer Edition API Service.

Note: The AP Java only supports bytes converted from the string data type.
If any other data type is directly converted to bytes and passed as an input to the API that supports byte as an input and provides byte as an output, then data corruption might occur.

Supported data types for the AP Java

The AP Java supports the following data types:

  • byte[][]
  • Double[][]
  • Float[]
  • Integer[]
  • java.util.Date[]
  • Long[]
  • Short[]
  • String[]
  • char[][]

The following are the various APIs provided by the AP Java.

getProtector

The getProtector method returns the Protector object associated with the AP Java APIs. After initialization, this object is used to create a session. The session is passed as a parameter to protect, unprotect, or reprotect methods.

static Protector getProtector() 

Parameters
None

Returns
Protector Object: Object associated with the Protegrity Application Protector API.

Exception
ProtectorException: If the configurations are invalid, then an exception is thrown indicating a failed initialization.

getVersion

The getVersion method returns the version of the AP Java in use.

public java.lang.String getVersion()

Parameters
None

Returns
String[]: Product version

getVersionEx

The getVersionEx method returns the extended version of the AP Java in use. The extended version consists of the Product version number and the CORE version number.

Note: The Core version is a sub-module which is required for troubleshooting protector issues.

public java.lang.String getVersionEx()

Parameters
None

Returns
String: Product version and CORE version

getLastError

The getLastError method returns the last error and a description of why this error was returned. When the methods used for protecting, unprotecting, or reprotecting data return an exception or a Boolean false, the getLastError method is called that describes why the method failed.

public java.lang.String getLastError(SessionObject session)

Parameters
Session: Session ID that is obtained by calling the createSession method.

Returns
String: Error message

Exception
ProtectorException: If the SessionObject is null, then an exception is thrown.

reprotect - Char array data

It reprotects the data provided as a char array that uses a preservation data type or a No Encryption data element. The protected data is first unprotected and then protected again with a new data element. It supports the bulk reprotection. There is no maximum data limit. However, you are recommended to pass not more than 1 MB of input data for each reprotection call.

If you are using the reprotect API, then the old data element and the new data element must have the same data type. For example, if you have used Alpha-Numeric data element to protect the data, then you must use only Alpha-Numeric data element to reprotect the data.

public boolean reprotect(SessionObject sessionObj, String newDataElementName, String oldDataElementName, char[][] input, char[][] output, byte[] newExternalIv, byte[] oldExternalIv)

Parameters
sessionObj: SessionObject that is obtained by calling the createSession method.
newdataElementName: String containing the data element name defined in policy to create the output data.
olddataElementName: String containing the data element name defined in policy for the input data.
input:Input array with char format data.
output: Resultant output array with char format data.
newexternalIv: Optional parameter, which is a buffer containing data that will be used as external IV, when newExternalIv = null, the value is ignored.
oldexternalIv: Optional parameter, which is a buffer containing data that will be used as external IV, when oldExternalIv = null, the value is ignored.

Result
True: The data is successfully reprotected.
False: The parameters passed are accurate, but the method failed to perform the required action.

For more information, such as a text explanation and reason for the failure, call getLastError(session).
