Abstract The growth in electronic transactions has resulted in a greater demand for fast and accurate user identification and authentication. Access codes for buildings, bank accounts, and computer systems often use personal identification numbers (PINs) for identification and security clearances. Conventional methods of identification based on possession of ID cards or exclusive knowledge like a social security number or a password are not altogether reliable. An embedded fingerprint biometric authentication scheme for automated teller machine (ATM) banking systems is proposed in this paper. In this scheme, a fingerprint biometric technique is fused with the ATM for person authentication to ameliorate the security level.
