Double Encryption Based Secure Biometric Authentication System

ABSTRACT: Nowadays bio-metric authentication systems are widely used in order to provide authentication without possessing any physical materials. Bio-metric authentication systems are mainly concentrating on security, revocability, privacy, and accuracy. In this paper, we propose a provably two way secured biometric authentication system, which addresses the concerns of user's privacy, template protection, trust issues, network security, and accuracy. The system is two way secured in the sense, biometric details are going to be encrypted twice, the system won't reveal any additional information about the user or biometric, to the authenticating server's database or to the insecure network. In this system two different encryption algorithms have been used both in the client and server side. One is public key cryptography another one is private key cryptography. User's privacy as concern it is revealing only the identity of the user. In template protection this protocol will store the template as encrypted form. Protocol will provide trust between remote user and server, while a remote user cannot be reliably identified without biometric information. Since network security as concern protocol is not revealing the plain biometric details while it is passed through the network. The proposed approach has no restrictions on the biometric data used and it is applicable for multiple biometrics (face, iris, hand geometry, and finger print). Authentication by using two way encryption will give additional layer of security when comparing with existing systems
