Abstract:
Disclosed are various embodiments for detecting replay attacks in voice-based authentication systems. In one embodiment, audio is captured via an audio input device. It is then verified that the audio includes a voice authentication factor spoken by a user. The audio is then compared with stored audio spoken by the user. If it is determined that an exact copy of the voice authentication factor is in the stored audio, one or more actions may be performed.

Claim (Index 15):
A system, comprising:\n at least one computing device; and a voice-based authentication service executable in the at least one computing device, wherein when executed the voice-based authentication service causes the at least one computing device to at least:\n receive audio captured via an audio input device; \n verify that the audio includes a voice authentication factor spoken by a user; \n detect a signal present in the audio indicating that the voice authentication factor is likely replayed from a recording; and \n perform at least one action in response to detecting the signal, the at least one action comprising at least one of: causing a notification of authentication failure to be played by a speaker, requesting that the user provide another authentication factor, sending a notification to an administrator, blacklisting a network address, disabling access to an account associated with the user, storing the audio in a data store, or causing a honeypot mode to be entered by the one or more computing devices.
