Authentication is a critical part of any trustworthy computing system which ensures that, only individuals with corroborated identities can log on to the system or access system resources. Biometric authentication with cryptography has ameliorated the security level for authentication. In this paper, a Bio-metric system for encrypting the user password is proposed for secure remote ATM transaction. A retinal image is acquired at transaction terminal and Bio feature points are extracted from the blood vessel tree. User password is encrypted using some selective feature points. After transmission to the central server, encrypted password is decrypted using stored Bio-key to extract the password and check with the stored password. The success of the transaction is based on the stored database.
