Bio-Cryptosystem Using Fuzzy Vault Scheme

Abstract

— In recent years most challenging problem is protection of information from unauthorized users. The conventional Cryptographic systems are insufficient to provide a security. The main problem is how to protect private keys from attackers and Intruder such as in case of Internet Banking. Cryptographic systems have been widely used in many information security systems. Hence in this paper we have proposed a framework of Biometric based cryptosystems. It provide reliable way of hiding private keys by using biometric features of individuals. A fuzzy vault approach is used to protect private keys and to release them only when legitimate individual enter their biometric sample. The main advantage of this system is there is no need of storing biometric information. However, fuzzy vault systems do not store directly these templates since they are encrypted with private keys by using novel cryptography algorithm. In proposed framework we are combining iris features with the encryption algorithm that can be a new research direction. The proposed approach provides high security and also image information can be protected.
