Fuzzy Vault Fingerprint Smartcard Implementation Using an Orientation-Based Feature Vector

With the increasing employment of biometric authentication systems worldwide, there has been significant concern over the security of stored biometric templates. In this paper, a solution to this problem employing a fuzzy vault fingerprint smartcard implementation, unlocked via an orientation-based feature vector, is presented. The fuzzy vault contains an unknown key which can be used either for identification or for file encryption/decryption.
