摘　　要：针对传统的纸质考试操作过程复杂,电子化试卷面临各种网络攻击技术,为确保试卷进行数字化安全性与保密性的管理,设计基于加密全息技术的试卷管理系统。通过Java语言与MySQL数据库设计一个能够同时支持学生、教师与管理员登录的系统对试卷进行所需要的管理与操作,与此同时把数字全息技术与Contourlet⁃SVD结合起来,设计出以Contourlet⁃SVD域数字全息为基础的水印加密算法,再将加密后的试卷录入系统后进行一系列管理。用户通过该系统不仅能够将试卷进行保存并通过系统自动生成试卷,还能够快捷便利地进行类似于试卷信息查询、增加、修改、删除等操作,以及相关信息的统计分析、保存等管理工作,全方位实现了对试卷的数字化、信息化、在线化的快速管理,有效地优化了教学管理的工作质量与工作效率。试卷在完成加密后用户通过登录模块进入系统,将完成加密的试卷进行录入与保存以便于后续的管理与使用。In allusion to the complex operation process of traditional paper exams and the various network attack technolo⁃gies faced by electronic examination paper,an examination paper management system based on encrypted holographic technology is designed to ensure the digital security and confidentiality of examination paper.A system that can simultaneously support stu⁃dents,teachers,and administrators to log in to the system is designed to manage and operate examination papers by means of Java language and MySQL database.At the same time,digital holography technology is combined with Contourlet⁃SVD to design a watermark encryption algorithm based on Contourlet⁃SVD domain digital holography,and then the encrypted examination paper are recorded into the system for a series of management.By means of this system,users can not only save examination paper and automatically generate them,but also quickly and conveniently perform operations such as querying,adding,modifying,deleting examination paper information,as well as the statistical analysis,storage and other management work of relevant infor⁃mation.It can achieve comprehensive digitization,informatization,and online rapid management of examination paper,effec⁃tively optimizing the quality and efficiency of teaching management.After completing the encryption of the examination paper,user can enter the system by means of the login module to enter and save the encrypted examination paper for future manage⁃ment and use.
