Abstract
The main issue of all the security and verification system is authentication and security by the user. This is needed to the enhancement of a mechanism which ensures users' privacy and security. This is a vast research area to develop security system in this field and different types of technologies have been proposed earlier. The conventional methods use tokens and passwords for providing security to the users and this system is compromised by hackers and also necessity to verification system design to ensure authentication and provide more security to the users. In recent years researchers have combined the key generation of cryptographic and biometrics method. The important features of biometrics are, it is a template which is not possible to revoke by an unauthorized person. The very familiar soft biometric features are the iris, retina, face, fingerprint, voice and so on. There is a cryptographic key generation technique Fuzzy Vault combine's soft biometrics. Providing more security to the users is necessary to avoid attacks. This technique gives an additional layer of security. Since this technique combines soft biometrics as well as cryptographic key generation which overcomes the limitation of biometric system when implemented individually. This paper proposes fuzzy vault scheme which uses retina as a soft biometric and gives best results when the performance is compared with other authentication system in ensuring the authentication.
