摘要
针对现有的现代远程教育在线考试系统中容易出现的考试替考、考试纠纷和网络攻击等诸多问题,提出了一种基于人脸识别跟踪和公钥密码体系的现代远程教育在线考试系统。该系统可以通过使用人脸识别跟踪技术解决考试替考问题,通过数字签名技术解决考试纠纷问题,通过公钥密码学技术防止网络传输差错并解决网络攻击问题。理论分析和实验验证说明,该系统能够有效解决考试替考、考试纠纷和网络攻击等问题,从而为远程教育在线考试系统的大规模应用提供了技术保障。
A novel online examination system based on human face tracking and public key cryptography is proposed because of many problems（such as examination cheating,examination dissension,network transmission error and network attack etc.） existing in current online examination system of modern long-distance education.In this online examination system,the examination cheating problem is solved by human face recognition and tracking technique,the examination dissension is solved by digital signature technique,and the network transmission error and network attack is prevented by public key cryptography technique.Theoretic analysis and experiments show that the proposed online examination system can efficiently solve examination cheating,examination dissension,network transmission error and network attack problems.Accordingly,the propoosed online examination system can efficiently guarantee the large-scale application of online examination system in modern long-distance education.
