Enhancing the Security of Biometrics in ATM

Biometrics based authentication provides various advantages over other authentication methods, it has replaced the password based authentication and token based authentication. Biometrics plays a major role in Automated Teller Machine (ATM) system, E-Commerce, Online banking, Passports. The growth in electronic transactions has been increased tremendously; there is a greater demand for fast and accurate user identification and authentication. In distributed system like ATM system the security is a main issue. The security levels have been grown from providing PIN (Personal Identification Number) to Smart Card to Biometrics. Even though the security has been increased, at the same time fraudulent activities have grown to equal level. So to overcome the hacking activities, the proposed work is developed to provide protection to the biometric template and to enhance the security in the ATM system with Multibiometrics, Multimodal biometrics and Two-tier security. Biometrics along with cryptography is used to encrypt the template which is stored in the database. Biometric cryptosystem scheme namely fuzzy vault and fuzzy commitment is used to protect the template which is extracted from the biometrics.
