Title
(EN) Method and system for identifying identity
(ZH) 身份识别方法及系统
Abstract
(EN)
The invention discloses a method and a system for identifying an identity. The method comprises the following steps: generating a biological characteristic model corresponding to a user registration identity mark when a user registers; generating and displaying a verification text and recording a voice and an image of a user reading verification text when the user identity is identified; identifying the recorded voice and image of the user reading verification text, thereby acquiring a valid starting time of the voice, the text content of the voice, the valid starting time of lip motion and a lip language text content; acquiring biological characteristics of the user if the valid starting time of lip motion conforms to the valid starting time of the voice and the lip language text content and the text content of the voice both conform to the verification text; matching the acquired biological characteristics with the biological characteristic model in a user register database, thereby acquiring a matching score; confirming if the user identity is correct according to the matching score. The method provided by the invention can be utilized to effectively increase the safety of the identity identification.

本发明公开了一种身份识别方法及系统,该方法包括:在用户注册时,生成对应用户注册身份标识的生物特征模型;在进行用户身份识别时,生成并显示验证文本,并录入用户朗读验证文本的语音和图像;对录入的用户朗读验证文本的语音和图像进行识别,得到语音的有效起始时间及语音文本内容、唇动的有效起始时间及唇语文本内容;如果唇动的有效起始时间与语音的有效起始时间相符,并且唇语文本内容和语音文本内容均与所述验证文本相符,则获取用户的生物特征;将获取的生物特征与用户注册数据库中的生物特征模型进行匹配,得到匹配得分;根据匹配得分确定用户身份是否正确。利用本发明,可以有效提高身份认证的安全性。
