In this paper, we propose a scheme of a biometric vault for enhancing the security of biometric systems. Many biometric systems are using traditional methods which are wide open to attacks. With increasing use of biometrics, there is a real threat for the conventional systems using databases, which store images of users in raw and unaltered form. If compromised, it is not only irrevocable, but can also be misused for cross-matching across different databases. By using passwords for user and biometric vault authentication, we can achieve a better level of security for the biometric system. Data hiding is performed by generating a key file and interjecting it to cancellable biometric data. For verifying data integrity, MD5 hashes are stored using standard AES-256 encryption cipher. Also to show that existing biometric matching systems will have acceptable alteration to be incorporated.
