Abstract: A method for performing a key recovery process is disclosed. The method comprises entering, in a user device, a user identifier unique to a user. The user device may then obscure the user identifier to form an obscured user identifier. The user device may then transmit the obscured user identifier to a first and second entity computer. The method may then include the first entity computer generating a first output using the obscured user identifier and a first share, and the second entity computer generates a second output using the obscured user identifier and a second share. As a response to transmitting the obscured identifier, the user device may receive the first output from the first entity computer and the second output from the second entity computer. The user device may then generate a secret key after processing the first output and the second output, completing the key recovery process.

Abstract: A method is disclosed. The method includes generating, by a first user device in association with a second user device, a second secret key on the second user device. The second secret key is derived from a first secret held by the first user device. The method includes generating a first commitment, transmitting., to the second user device, the first commitment, receiving, from the second user device, a second commitment, receiving, from the second user device, a random value and a ciphertext. The ciphertext is generated using the first commitment, the second commitment, and the random value. The method also includes verifying the ciphertext, and in response to verifying the ciphertext, modifying a group to include the second user device.

Abstract: Described herein are a system and techniques for identifying and preventing certain fraud attacks that may be used to defeat facial recognition systems. In embodiments of the system described herein, biometric data may be segregated into regions, which are then processed separately and in parallel. Likeness scores are determined for each of the separate regions. By tracking individual region likeness scores used in access requests in accordance with embodiments of the disclosure, the system is able to identify potential fraud attacks that cannot be detected using conventional systems.

Abstract: A method and system of using a vehicle mounted camera device to authenticate a user during an interaction is disclosed. The method includes receiving interaction data regarding an interaction between a user operating a communication device and an access device, the user being near other candidate users. The method then includes determining one or more match indicators, the match indicators generated by comparing different sample biometric templates of the user with different enrolled biometric templates. At least one of the different biometric sample templates may be an image-based biometric template and at least one may be a voice print biometric template. Then the method includes identifying the user based on at least the match indicator associated with the voice print biometric template. The method then includes, if the match indicators are positive match indicators, initiating a process on behalf of the user.
