摘　　要：基于单一生物特征模糊金库证易于受到相关攻击而导致生物特征模板泄露的安全性问题,提出一种基于两枚不同手指指纹的特征融合模糊金库的身份认证方案。这种身份认证方案采用了分别来自两枚不同手指指纹的细节点与方向场进行融合的方法,基于Diffie-Hellman密钥交换协议思想。实验结果表明该身份认证方案在指纹特征模板的安全性保护上比基于单一指纹特征模板有显著提高。The fuzzy vault based on single biometric characteristics is vulnerable to correlation attacks which may induce the biometric template leakage.An identification scheme based on the fuzzy vault scheme using feature fusions of two different fingerprints is proposed.The identification scheme employed the fusion of detail points and direction fields from two different finger fingerprints.The feature fusion method used Diffie-Hellman key exchange protocol s idea to realize the feature fusion.The experimental results show that our identification scheme can significantly improve the security of fingerprint feature template compared with the single fingerprint feature template.
