Method and system for secure device based biometric authentication scheme

Abstract:

A method for device based biometric authentication includes: storing, in a computing device, an encrypted biometric template; storing, in a first memory of the computing device, at least a first application program; storing, in a second memory of the computing device, at least a second application program and an encryption key, wherein the second memory is a trusted execution environment; receiving, by the second application program of the computing device, a validation request submitted by the first application program; receiving, by an input device of the computing device, biometric data; decrypting, by the second application program of the computing device, the encrypted biometric template using the encryption key; validating, by the second application program of the computing device, the received biometric data using the decrypted biometric template; and transmitting, by the second application program of the computing device, a result of the validation to the first application program.
