Provided are systems for authenticating an individual using image feature templates that include at least one processor to train a first machine learning model based on a training dataset of a plurality of images of a user, generate a plurality of image feature templates using the first machine learning model, wherein each image feature template of the plurality of image feature templates is associated with a positive authentication of the identity of the user during a time interval, generate a second machine learning model based on the plurality of image feature templates, generate a predicted image feature template using the second machine learning model, determine whether to authenticate the identity of the user based on an input image of the user, and perform an action based on determining whether to authenticate the identity of the user. Methods and computer program products are also provided.

System, method, and computer program product for evolutionary learning in verification template matching during biometric authentication

Provided are a system, method, and computer program product for patient authentication and identity risk assessment. The method includes receiving an initial patient authorization request from a medical provider computing device. The initial patient authorization request includes a patient identifier communicated by a mobile device of a user to the medical provider computing device. The method also includes generating, using an identification risk assessment model and based at least partly on the initial patient authorization request, an authenticity score. The method further includes communicating the authenticity score to an insurance provider system to cause the insurance provider system to approve or decline the initial patient authorization request. The method further includes receiving a primary insurance provider response from the insurance provider system and communicating at least a portion of the primary insurance provider response to the medical provider computing device.

System, method, and computer program product for patient authentication and identity risk assessment

A method performed by a user device is disclosed. The method comprising generating a secret and measuring a biometric template of a user operating the user device. The method then generates a plurality of secret shares of the secret and of the biometric template. The user device then transmits the secret shares of the secret and of the biometric template to a plurality of recovery devices. After, the user device may then initiate a recovery of the secret and measure a biometric measurement of the user. Data of the biometric measurement may be transmitted to the plurality of recovery devices, where the recovery devices perform a partial computation. The user device use the plurality of partial computations to determine a match between the biometric template and the biometric measurement. If the two biometrics match, the user device can reconstruct the secret using shares of the secret from the recovery devices.

Distributed private key recovery

Provided is a system including at least one host application processor and at least one field programmable gate array (FPGA) device coupled to the at least one host application processor via a communication bus, the at least one host application processor is programmed or configured to receive a transaction data record comprising transaction data associated with a payment transaction, transmit the transaction data record to the at least one FPGA device via the communication bus, and receive an encrypted transaction data record from the at least one FPGA device via the communication bus, wherein one or more data fields of the transaction data record are encrypted to generate the encrypted transaction data record. A method and computer program product are also provided.
