基于唇语识别的身份认证研究及系统设计

Identity Authentication Research and System Design Based on Lip Reading Recognition

随着人脸识别身份认证技术的广泛应用,各类针对人脸识别系统的攻击手段逐渐出现.为了应对这类安全性问题,提出了基于唇语识别的身份认证方法.基于唇语识别的身份认证系统要求用户在进行人脸识别认证的同时读出验证码,系统既要对人脸进行比对,还要通过唇语识别技术识别出说话内容并与验证码进行比对,只有两部分比对都通过才能通过系统的身份认证.最后设计了基于唇语识别的身份认证系统,主要包括前端、网关和后端.

Amid the widespread application of face recognition technology for authentication,various attack methods against face recognition systems have emerged over time.An identity authentication system based on lip reading recognition is proposed to cope with such security issues.It requires users to read the verification code during face recognition for authentication.The system not only checks the face,but recognizes the content of the speech through the lip reading recognition technology to compare it with the verification code.The user’s identity can be authenticated only when both the two links are passed.Finally,an identity authentication system based on lip reading recognition is designed,mainly including front-end,gateway,and back-end.
