A Hybrid Approach for Face Template Protection

Biometric template protection is one of the important issues in deploying a practical biometric system. To tackle this problem, many algorithms have been reported in recent years, most of them being applicable to fingerprint biometric. Since the content and representation of fingerprint template is different from templates of other modalities such as face, the fingerprint template protection algorithms cannot be directly applied to face template. Moreover, the authors believe that no single template protection method is capable of satisfying the diversity, revocability, security and performance requirements.
