摘要：Biometric authentication mechanisms are receiving a lot of public attention. Biometrics based authentication is a potential candidate to replace passwordbased authentication. This paper aims at developing a novel authentication protocol by fusion of Biometric and Steganography techniques for secure processing of ATM Systems. Visual Steganography provides a very powerful technique by which one secret can be distributed in two or more shares. During the enrollment phase in the bank terminal, the user has to enroll his/her fingerprint and finger vein and these enrolled biometric images are required to undergo certain processing and the resultant images are encrypted using RSA algorithm with a secret key and by using the visual steganographic technique, the encrypted secret key is shared between the two images. In the verification procedure, new finger vein and fingerprint images are obtained in the ATM terminals and af ter processing of the acquired biometric images, it will be decrypted by RSA algorithm using the same secret key and those are verified with the images stored in the bank’s database. If matches with the database, then the user can carry out the money transactions and every user has three trials to access the ATM systems and if exceeds, the system will automatically logout the transaction. Since ATMs are now a normal part of daily life, the application of multimodal biometric techniques in every ATM Center’s in our country, leads to reduce the stealing and forging and it is very useful for all the people.
