摘　　要：远程身份认证是远程教育系统亟待解决的问题之一,为实现对学习者身份的实时认证,提出了基于人脸识别技术的身份认证方法。在对有关人脸识别技术分析的基础上,提出二阶双向二维主成分分析特征提取方法,减小了采集环境对人脸准确识别的影响。提出的方法可有效解决"用户名+密码"等目前广泛采用的静态认证方式带来的种种隐患,为远程教育的健康发展创造了有利条件。Distance identity authentication is one of the problems that should be solved urgently by distance educational system. In order to authenticate learners＇ identity momentarily, an identity authentication wethod based on the technology of face identity is presented in this paper. Based on the analysis of face identity technology, a way to extract the face feature of Sec-- （2D）2PCA has been put forward, and it decreases the influence of collecting environment on the face identity＇s accuracy. The method, presented in the paper, can not only solve effectively all kinds of hidden troubles brought by widely using static ways such as ＂user ＋ password＂ and so on, but also create an advantage for distance education＇s healthy development.
