Sniffing out the fakes – Google files patent apps for fingerprint and voice liveness

Google has filed a pair of patent applications for software capable of detecting spoofed voice and fingerprint biometrics that could be used to gain access to facilities and information.

The applications are 20230385393 A1, relating to localized illumination for biometric authentication, and 20230386506 A1, for self-supervised speech representations for detecting fake audio. Both were published November 30.
