电子文件保护系统的设计与实现

Design and realization of digital file protection system

为了解决现有的电子文件保护系统存在的问题,设计并实现了一种电子文件保护系统。首先分析了现有的电子文件保护系统存在的弊端,在此基础上提出了系统的设计思想,建立了总体设计框架,然后对系统的关键技术进行了详细地阐述,提出了一种隐藏文件加密标志的方法。设计了文件打开、文件读写和文件关闭的流程,并提出了一种移动介质控制方法。通过了权威机构的认证测试,测试结果表明,该系统安全性高、功能稳定、操作简洁、易于使用。最后,指出了电子文件保护技术的发展趋势。

To solve the problems in current digital file protection systems,a new digital file protection system is designed and realized.Firstly,the disadvantages of current digital file protection systems are analyzed,and the system design is presented,the design framework is constructed.Then the key techniques of the system are thoroughly depicted.A new way to hide the file encryption mark is put forward.The flows of file open,file read/write and file close are designed.A new way to control the mobile media is brought forward.Through the test of relevant authority,the system is proved to be secure,robust,compact and easy to use.Finally,the development direction of the digital file protection technology is demonstrated.
