A novel privacy enhancing algorithm for biometric system

Biometrics provide the possibility of unique and convenient authentication. As its application areas grow rapidly, the problems, such as identity fraud and cross matching, threaten the security of biometric systems. Moreover, privacy concerns are associated with biometrics. In this paper we focus on privacy enhancing techniques for biometric systems, which can protect biometric information and enable using biometrics without exposure of privacy. A novel privacy enhancing algorithm is proposed. The algorithm is integrated in a 3D face recognition algorithm and tested using the FRGC database. By using the proposed algorithm, high security can be achieved as well as good verification performance.
