A protocol to establish trust on biometric authentication devices

One of the most extensively utilized mechanisms for person authentication is a system built using biometric-based authentication. However, many applications use biometric authentication devices that do not support any device authentication mechanisms. As a result, a counterfeit scanning device may be substituted for the genuine one. Non-authentic biometric authentication devices may perform some additive / subtractive or malicious functions. This paper proposes a technique for establishing trust in biometric authentication devices. The device authentication procedure is essential to build trust in biometric authentication devices such that non-genuine biometric authentication devices are not used, which may compromise the loss of authentication factor and its replay when the genuine user is not getting authenticated. The protocol uses strong cryptographic mechanisms to authenticate the biometric authentication device with the application server and includes mechanisms for protection against the tampering of biometric templates and to prevent replay attacks. We also perform a formal verification using BAN logic to demonstrate that the proposed protocol meets the defined objectives. The proposed protocol can be used with any biometric authentication device to achieve the same objectives.
