生物特征密码系统提供了生物特征与传统密码学的有机结合.生物特征密钥可在隐藏用户的生物特征信息的同时,安全实现密钥的生成、恢复以及认证的多重功能.本文提出了一个基于指纹特征的密码密钥保存与生成算法.实验结果表明,密钥的成功恢复率可达到91%左右,具有一定的实际应用意义.
The biometric cryptographic system can provide the integration of biological features and the traditional cryptology. The use of biological keys can not only hide the user's biological feature information but also realize safe key generation, recovery and authentication. This paper proposes a scheme for secure key keeping and generation based on fingerprint features. The experimental results indicate that the success rate of the key recovery is about 91%, and it shows our algorithm is highly efficient and is of practical significance.
