Message verifications analyze the content of an audio to validate that the message found matches the one expected.

They can be used for knowledge-based or possession-based access control and to ensure that the audio is not pre-recorded.

Message verifications can make recording-based spoofing attempts unfeasible in identity and authenticity verifications and introduce complementary authentication factors.

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 messages found with the ones expected is powered by a specific version of a message verification model.

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