Traditional anti-tampering system can not guarantee its own security. in order to reduce tampering and ensure the integrity of Web pages and web server security and the stability of operation, the paper analyzes the current anti-tampering technology of several webs, and introduces the model three-threading technology based on the existing anti-tampering technology and the multi-ring structure of the node page tamper-resistant model. It can protect against tampering with the system. This paper describes the structures, working mechanism and the implementation process in details. The study illustrates that the security of the system on the website is guaranteed and the efficiency of the server is improved.
