Abstract
Device, system, and method of user authentication utilizing an optical microphone or laser-based microphone. An optical microphone transmits an outgoing optical signal or laser beam towards a face of a human speaker; receives an incoming optical feedback that is reflected back from the face of the human speaker; performs self-mix interferometry that is based on the outgoing optical signal and the incoming reflected optical signal; and generates a user-specific feature or characteristic that uniquely characterizes said human speaker. A user authentication module operates to authenticate the user for performing a privileged or an access-controlled action, based on the user-specific characteristic that was generated, optionally in combination with one or more biometric features or authentication requirements.
