Abstract:

Biometrics based authentication is a potential candidate to replace token-based authentication especially in Automatic Teller Machines (ATMs). The financial sector has used ATMs as a means to make payments and to offer financial services for its clients. But, security is a major issue in accessing these machines in particular for authenticating a group of users who have joint account in the financial institutions. So, in this study, a simple but efficient group authentication mechanism is proposed in which multimodal biometric is used for authenticating the group of customers instead of the existing practice of using multi ATM cards. Privacy and revocability are the main concern while using biometrics. So the biometric used are not stored as such instead a cancelable form, generated by genetic operator is stored and by that way privacy is protected and also revocability is ensured.
