Distributed File Synchronization System In The Webpage Tamper-proof

The main content of this thesis is the research on distributed file synchronization technology in web anti-tamper system. Nowadays, the events of tampered web page are commonly occurrence in the Internet and thus this phenomenon lead to disastrous loss. The emergence of the web anti-tamper system is effective prevents the possibility of tampering web pages. Therefore, this system protects the security of the information in the website well. Based on the internal structure of the anti-tamper system, this system is a complex multi-module system and each module linked closely, through the interaction between the modules in this system which can ultimately complete the protection of the webpage. The system that discusses in this thesis mainly solves the problems which are distributed release of the file and instantly recovery of the tampered webpage. These two problems are the essential components and also play the crucial role in the distributed file synchronization system.This thesis selects the web server core embedded tamper-resistant system as the main object of this research. The main research contents are as follows:1. It compares and summarizes the advantages and disadvantages of the various existing anti-tamper technology at home and abroad, and finally selects the web server core embedded anti-tamper technology as the main object of this research.2. It has a detailed analysis on the internal structure, functional module, working principle of the web server core embedded anti-tamper system. And this thesis also clearly understands the status and function of the distributed file synchronization system in the entire core embedded anti-tamper system.3. By collecting and consulting the relevant materials in this field, the author clearly understands the application of file synchronization technology in this thesis. And the author also analyzes some existing methods and strategies of improve the efficiency in file synchronization. Finally, the author puts forward the design idea of the file synchronization.4. The author designs a safe, reliable and stable distributed file synchronization system for web server core embedded anti-tamper system, and detailed elaborates its system architecture, working principle and the realization of the function. In this thesis, it implements a prototype system, and demonstrates the results of its operation.The distributed file synchronization system which has been completed in this thesis is safe and reliable.It is able to publish files safely, completely, accurately, distributed to one or more web server system configuration in the web page anti-tamper system. This system is also able to fast and accurately recovery the file when we found one webpage in one web server has been tampered.
