Patent attributes
Methods and apparatuses for enhanced user biometric authentication are described. In one example, authenticating a user includes storing user authentication pairs in a memory of an authenticator device, each authentication pair comprising an instruction prompt and a stored corresponding user response biometric to the instruction prompt. A request to authenticate a user is received at the authenticator device from an authentication requestor device. An instruction prompt is output from a selected authentication pair, and a current user response to the instruction prompt is received. A current user biometric is generated from the current user response. An identity of the user is authenticated by comparing the current user biometric to the stored corresponding user response biometric for the instruction prompt output.
