Biometric Digital Key Mechanisms for Telebiometric Authentication Based on Biometric Certificate

摘要

Existing biometric authentication systems use probabilistic method to decide the claimed identity of a user. But, these are weak on the privacy protection perspective as anyone can access someone's biometric template without restrictions. Therefore, we propose a scheme that can improve the biometric authentication accuracy with the concept of digital signature with biometric digital key. By using these biometric digital key pairs, each entity(sender) can mutually authenticate the others based on the biometric certificate on open network.
