Input Sanitization

Mon, 01 Jan 0001 00:00:00 +0000

The Classification service in Data Discovery offers a security feature that rejects unsanitized data. Data that is malformed, non-normalized, containing homoglyphs, hieroglyphs, mixed Unicode variants, or control characters are considered as unsanitized data. These are rejected for classification.

The following are few examples of data that will be rejected:

Before invoking the Classification endpoint, ensure that the input text is normalized. Replace invalid characters by their corresponding normalized plaintext characters. If the input text contains any invalid character, a status code of 422 and a message Untrusted input is returned.
