Biometric Authentication Scheme for ATM ...

This paper presents a highly secured ATM banking system using an optimized Advanced Encryption Standard (AES) algorithm. Two levels of security are provided in this proposed design. Firstly we consider the security level at the client side by providing biometric authentication scheme along with a password of 4-digit long. Biometric authentication is achieved by considering the fingerprint image of the client. Secondly we ensure a secured communication link between the client machine to the bank server using an optimized energy efficient AES processor. The fingerprint image is the data for encryption process and 4-digit long password is the symmetric key for the encryption process. To get a low power consuming ATM machine, an optimized AES algorithm is proposed in this paper. In this system biometric and cryptography techniques are used together for personal identity authentication to improve the security level. The design of the energy efficient AES processor is simulated in quartus-II software. Simulation results ensure its proper functionality. The realization of a demo hardware is also provided in this paper. A comparison among other research works proves its superiority.
