Automated means of checking whether a subject is a real person

A liveness test, liveness check or liveness detection is an automated means of checking whether a subject is a real person or part of a spoofing attack.

In a video liveness test, users are typically asked to look into a camera and to move, smile or blink, and features of their moving face may then be compared to that of a still image. Artificial intelligence is used to counter presentation attacks such as deepfakes or users wearing hyperrealistic masks, or video injection attacks. The technique is used as part of know your customer checks in financial services and during facial age estimation.

Other forms of liveness test include checking for a pulse when using a fingerprint scanner or checking that a person's voice is not a recording or artifically generated during speaker recognition.
