Patent attributes
Systems and methods for authentication with resistance to replay attacks are provided. A device may be used to capture image data of a physical token to authenticate or identify a user. Authentication information may be obtained by processing and analyzing the captured image data. Data about a state of the imaging device and the captured image data may be used for fraud detection. The data may be collected when the image data is processed and analyzed. The state of the imaging device and captured image data are unlikely to be repeated. The detected repetition of a state of the imaging device and captured image data may be a cause for increasing the likelihood that a replay attack is taking place. The device may be used to perform a transaction.
