Abstract: Systems and methods for authenticating a user are provided. A method may comprise providing interactive media on a computing device associated with a user. The interactive media may comprise a plurality of images. The plurality of images may be presented on a graphical display of the computing device. The method may also comprise receiving input data from the computing device when the user selects a sequence of images from the plurality of images on the graphical display of the computing device. The selected sequence of images may correspond to a sequence of grammatical words. The method may further comprise analyzing the input data by comparing the sequence of grammatical words to a passcode, and authenticating the user when the sequence of grammatical words is equal to the passcode.

Abstract: 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.

Abstract: Systems and methods for detecting replay attacks are provided. One or more sensors may be used to collect data about a state of a device. The device may be used to perform a transaction. The device may be used to authenticate or identify a user. The state of the device may pertain to a characteristic of the device position, movement, component, or may pertain to one or more environmental conditions around the device. The state of the device may be expected to change over time, and certain states are unlikely to be repeated. The detected repetition of a state of the device may be a cause for increasing the likelihood that a replay attack is taking place.
