基于表情图像变形的动态口令认证系统

为解决当前身份认证系统存在的安全性问题,分析和比较了传统身份认证和一次性口令的相关技术,指出其在开发式网间进行传输时,容易受到截取和重放攻击以及伪造服务器的恶意欺骗.在分析了人脸表情变形技术特点的基础上,针对现有OTP系统对智能硬件过于依赖以及无法有效防伪服务器恶意欺骗等不安全因素,结合人脸表情变形的特点,提出将变形图像及其隐含的变形参数序列作为可变因子,取代现有OTP口令系统中的传统可变因子,以解决现有OTP系统在传输安全及服务器恶意欺骗防伪等方面的不足.最后设计完成了一个可实用化的基于人脸表情图像变形技术的一次性口令认证系统原型.

Dynamic password authentication system based on facial image deformation

To deal with the security trouble of current authentication system, the technology of traditional authentication and one time password authentication are analyzed and compared, some shortcomings of them are pointed out such as interception, replay attacks and fake-server in case of the authentications through an open network. According to the analysis of the characteristic of facial expression morphing technology, a dynamic password identity authentication system based on technology of facial expression mor...
