结合人脸特征和密码技术的网络身份认证系统符艳军 程咏梅 董淑福 王晓东


摘 要:为了解决传统密码或单纯生物特征在远程身份认证中存在的安全问题,利用人脸识别中特征模板的生成特点,设计了一种人脸特征与密码技术相结合的双重身份认证方案。人脸识别的仿真结果证明了人脸特征用于识别的有效性;系统分析表明,该系统能够对付传统网络身份认证中所遇到的窃听、重放、假冒或窜改等各种攻击,且实时性比较好。

  Abstract:In order to solve the security problems existed in the process of remote authentication which based on classical cryptography or biometric only,proposed a dual network authentication system based on the feature template of face recognition, which bound face with cryptography. Experimental results indicate that face recognition is efficient, and the system analysis shows that the proposed system can not only provide solutions to many of these problems such as playback, fraud and alteration etc., but also be a real-time system. ......
