A Hybrid Approach for Generating Secure and Discriminating Face Template

Biometric template protection is one of the most important issues in deploying a practical biometric system. To tackle this problem, many algorithms, that do not store the template in its original form, have been reported in recent years. They can be categorized into two approaches, namely biometric cryptosystem and transform-based. However, most (if not all) algorithms in both approaches offer a trade-off between the template security and matching performance. Moreover, the authors believe that no single template protection method is capable of satisfying the security and performance simultaneously.
