一种基于数据隐藏和可撤销模板的生物特征信息保护方案

A Biometric Template Protection Scheme Based on Data Hiding and Cancelable Biometric Template

为了抵抗传统生物认证方案中易受的攻击，确保用户信息安全，通过结合用户密码实现双因子生物认证的方法，提出了一种基于数据隐藏和可撤销模板的生物特征信息保护方案，并通过MD5哈希算法和AES-256加密算法，确保了生物信息的完整性。实验证明，本方案有效隐藏了生物特征信息，相比其他方案具有更高的安全性和效率。

In order to resist attacks in traditional users,This paper proposed a biometric cancelable template by using password For The pare verifying the data integrity, MD5 experiment results show that the d with others. template biometrie schemes and ensure the security of protecting scheme based on data hiding and s, and realized a two-factor biometric authentication. hashes are stored followed scheme achieved higher se with AES-256 eneryption. curity and efficiency compared with others.
