Enhancing Biometric Security with Combinatorial and Permutational Multi-Fingerprint Authentication Strategies

Biometrics provide an efficient solution for user authentication as researchers and practitioners are using biometrics to increase the ease of usage and to ensure the privacy and security of applications. In this paper, we propose a method to improve the accuracy of the biometric authentication system by decreasing the False Acceptance Rates (FAR) and the False Rejection Rates (FRR). We examine the effect of having different combinations and permutations of fingerprint samples to specify a multi-factor authentication scheme. We find that our approach reduce the attack on the system by imposters and improve the accuracy of the biometric authentication systems by reducing the two used metrics of error.
