Abstract:
Device, system, and method of voice-based user authentication utilizing a challenge. A system includes a voice-based user-authentication unit, to authenticate a user based on a voice sample uttered by the user. A voice-related challenge generator operates to generate a voice-related challenge that induces the user to modify one or more vocal properties of the user. A reaction-to-challenge detector operates to detect a user-specific vocal modification in reaction to the voice-related challenge; by using a processor as well as an acoustic microphone, an optical microphone, or a hybrid acoustic-and-optical microphone. The voice-based user-authentication unit utilizes the user-specific vocal modification, that was detected as reaction to the voice-related challenge, as part of a user-authentication process.

Claim (Index 18):
The system of  claim 1 ,\n wherein the reaction-to-challenge detector comprises a laser self-mix microphone and an associated processor, wherein the laser self-mix microphone (i) transmits an outgoing laser beam towards said user, and (ii) receives incoming optical feedback reflected from said user in response to said outgoing laser beam hitting said user, and (iii) performs laser self-mix interferometry of said outgoing laser beam and said incoming optical feedback, and (iv) by utilizing said associated processor, generates a user-specific characteristic that characterizes user-specific facial vibrations of said user in response to said voice-based challenge; wherein said voice-based user-authentication unit utilizes said user-specific characteristic that characterizes user-specific facial vibrations of said user in response to said voice-based challenge, as part of said user-authentication process.
