A biometric server receives, a transmission of a biometric sample and an encrypted enrollment template of the user from a client device, wherein the encrypted enrollment template comprises an encrypted mathematical representation of historical biometric data of the user, and wherein the biometric sample comprises a current snapshot of the biometric data. The biometric server decrypts the encrypted enrollment template to an enrollment template using an enrollment template key. The biometric server converts the biometric sample to a biometric template. The biometric server, based on determining that the biometric template is similar to the enrollment template associated with the user, sends an access token to the client device.
