Research Of Dynamic Detection System For Web Based File Management

With the development of information technology, computer system and the Internet is widely used. Various forms of web contain rich information. Because the network not only has the features of connection diversity and openness but also has many factors of insecurity, resulting in sites are vulnerable to hackers, Trojans and other malicious attacks. It brings many issues such as the files are altered or deleted and so on, so the network is insecure. Under such circumstances, dynamic detection technology for web has become a new hotspot. Dynamic detection based on file management, which is designed to master file information which has been changed, and according to the requirement to insert, delete and modify. The study objective of dynamic detection for web is text file which is the most common form of information storage, so the research of dynamic detection has very broad prospects.Currently, text comparison algorithms have been mainly used in the field of file proofreading and the way to solve the maximum matching rate and the optimal matching paths and so on. However, in the dynamic detection systems for web, the application of text comparison algorithms is very little. To address this issue, according to the characteristic of files used in web and the need of application, dynamic detection system for web is designed and developed, which is based on file management and use a text comparison algorithm. This system achieves the regular detection for web, and through the proposed algorithm to manage files on the web.Firstly, the main technology and research status of text comparison is analyzed. And then, Text Comparison Algorithm Based on the Locality is proposed according to the characteristic of the dynamic detection for web. The matching process of this algorithm which is easy to comprehend and can effectively determine whether a file has been tampered with is relatively simple. Secondly, according to the needs of dynamic detection, in order to realize the function of recover and update, the original information and change information were stored in database respectively. Lastly, a dynamic detection system for web with friendly interface is developed which based on file management. The system is developed under the circumstance of Eclipse and My SQL.
