Identity Verification

Identity verifications analyze the similarity between the biometric characteristics of an audio and those encapsulated by a voiceprint to validate that they belong to the same identity.

They can be used for biometric-based access control or to validate that the voice of a media fragment belongs to a certain speaker.

Combining identity verifications with authenticity and message verifications can greatly improve robustness against spoofing attempts.

Access: To manage a verification, you must have access to its space.

Isolation: A verification can only interact with resources inside its space.

Model: The analysis and comparison of the biometric characteristics of the voice is powered by a specific version of an identity verification model.

Score: Confidence in a positive result is represented by the score.
