网页防篡改和自动恢复系统

目前存在的网页防篡改和自动恢复技术主要有三种:时间轮询技术,事件触发技术+核心内嵌技术和文件过滤技术+事件触发技术。这三种方式都是对目标文件进行监控,当目标文件被篡改时就从备份文件中还原出原文件,但是却没有对备份文件做保护,如果备份文件被破坏,则无法正常的恢复原网页文件,所以在文件过滤+事件触发技术的基础上,研究了如何去使用MD5校验,DES加密,文件重命名等三种方式去保护备份文件的安全性。

Web Page Tampering Prevention and Automatic Recovery System

The existing web prevent tampering and automatic recovery technology mainly have three at present: time polling technology,event trigger technology + core embedded technology,file filtering technology + event trigger technology.All the three ways monitor the target file when the target file is tampered,it will return to the original condition from backup files in the file,but the backup files weren’t protected,if the backup files were destroyed,the web pages won’t be returned to its original condition.So in file filtering + event trigger technology foundation,this paper studies how to use MD5 calibration,DES encryption,file renaming,three ways to protect the safety of backup files.
