Liveness Detection
A biometric verification technique that confirms the operator is a real person rather than a photograph or video forgery by requiring actions such as blinking or turning the head. It is commonly used in financial account-opening processes to prevent spoofing attacks.
Timeline (last 90 days)
Liveness detection requires users to complete actions such as blinking and turning their heads when opening an account, to confirm that the operator is a real person and not a photo or video forgery, which can significantly raise the threshold for impersonation registration.
Industry approaches to addressing voiceprint vulnerabilities include introducing liveness detection that requires users to read random phrases aloud, combining device binding and behavioral baselines as auxiliary signals, and falling back to out-of-band channels for highly sensitive operations.
