Patent Primary Examiner
In order to detect a replay attack on a voice biometrics system, a first signal from received sound is generated at a first microphone, and a second signal from the received sound is generated at a second microphone. The first and second signals are used to determine a location of an apparent source of the received sound. It is determined that the received sound may result from a replay attack if the apparent source of the received sound is diffuse.
