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 8):
A method, comprising:\n receiving, via at least one of one or more computing devices, audio captured via an audio input device; verifying, via at least one of the one or more computing devices, that the audio includes a voice authentication factor spoken by a user; comparing, via at least one of the one or more computing devices, the audio with stored audio spoken by the user; determining, via at least one of the one or more computing devices, that an exact copy of the voice authentication factor from the audio is also in the stored audio; and performing, via at least one of the one or more computing devices, at least one action in response to determining that the exact copy of the voice authentication factor is in the stored audio, 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.
