英文摘要：

In this paper, the significance of network construction was analyzed, the status of network monitoring was introduced, and the difference of common web page tamper-resistant technologies in reality were compared. While noting the insufficience of the former, the concept of web page matching properties were suggested, giving the principle of matching properties selected, then the text detection method based on the matching properties was proposed. Finally, the batch web page tamper-resistant system based on snapshot polling and text detection was designed and implemented, and the main technologies in details and the framework were given. A systematic test was conduted, and the strengths and weaknesses of the system were analyzed. The future research direction was discussed.
