Enhanced biometric user authentication
First Claim
1. A method for using a body worn device comprising:
- storing a plurality of user authentication pairs in a memory of a body worn device comprising a head-worn device, each authentication pair comprising a challenge question and a corresponding voiceprint of a user spoken answer to the challenge question;
receiving at the body worn device from an authentication requestor device a request to authenticate a user;
generating a random number;
selecting a first challenge question from a selected authentication pair from the plurality of user authentication pairs, wherein the selected authentication pair is selected utilizing the random number;
outputting the first challenge question at a speaker of the body worn device;
receiving a user spoken response at a microphone of the body worn device;
generating a response voiceprint from the user spoken response; and
authenticating an identity of the user comprising comparing the response voiceprint to a first corresponding voiceprint to the first challenge question.

Abstract
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.

5. A head worn authenticator device comprising:
-
a microphone; a speaker; a wireless communications transceiver operable to receive an authentication request from an authentication requestor device; a processor; and a memory comprising; two or more user authentication pairs, each authentication pair comprising a challenge question and a corresponding voiceprint of a user spoken answer to the challenge question; and an application program comprising executable instructions to receive the authentication request, generate a random number, output audio at the speaker a first challenge question selected from the two or more user authentication pairs utilizing the random number, receive a user spoken response at the microphone and generate a response voiceprint from the user spoken response, and validate an identity of a user by comparing the response voiceprint to the corresponding voiceprint to the first challenge question. - View Dependent Claims (6, 7, 8, 9)
