Double encryption based secure fuzzy vault construction using fingerprint biometric features

Security has become one of the major concerns in the present scenario because of the increase in quantity of data and theft. Due to these reasons, an efficient security system is very much necessary for protecting the authorized properties. This leads to the usage of password, key, etc., for securing the system. This security system can be easily broken because the password and key can be easily lost by the user. Also, the users have to memorize the password and key for access to the system and sometimes the user may forget the password and key. This has forced the researchers for developing a better security system. Then, the usage of biometrics evolved to be better technique for security purpose as biometrics is unique for every individual. Mostly used biometrics features for security purpose are fingerprint, iris, retina, palm, face, etc. This paper focuses on using the fingerprint as biometrics for developing a security system. The security is enhanced in this paper by using double encryption technique by means of combining symmetric key and a symmetric key generation. Also, Reed and Solomon codes are used to provide tolerance for decryption. The experimental result shows that the proposed Fuzzy Vault construction results in proving better security.
