Encrypted Fuzzy Vault Based on Fingerprint
Biometrics is the only factor that is directly linked with the distinguishing characteristic of an individual and has been widely applied to identity authentication, biometricsbased key management system may be expected to be a powerful competitor in the future. A popular technique of such a system is the fuzzy vault scheme. In this paper, a new scheme is proposed, which referred to as encrypted fuzzy vault scheme. The fingerprint-based implementation also is presented. In locking phase, a secret key is encrypted by the key derived from a set of random data. Then these data are encoded on the fingerprint minutiae. At last, the minutiae are encrypted by the private list. By these ways, the construction of the encoding polynomial is decoupled from the size of the secret key and less storage is required, but the higher level of security is achieved.
