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 1):
A system comprising:\n a voice-based user-authentication unit, to authenticate a user based on a voice sample uttered by said user; a voice-related challenge generator, to generate a voice-related challenge that induces said user to modify one or more vocal properties of said user; a reaction-to-challenge detector, to detect a user-specific vocal modification in reaction to said voice-related challenge; wherein the voice-based user-authentication unit utilizes said user-specific vocal modification, that was detected as reaction to said voice-related challenge, as part of a user-authentication process that either approves or denies authentication of said user.
