Embodiment Construction

[0059] Such as figure 1 As shown, the system of the present invention includes a module for automatically generating similar URLs or all possible URLs, a webpage similarity calculation module for judging whether two webpages are similar, and an alarm module. The system can be installed on the enterprise's own server or on the server of an intermediary agency. When running, the system first invokes the URL generation module to generate all URLs similar to real URLs or all possible URLs. There are many ways to generate similar URLs in this module. For example, the symbols in the real URL are replaced by similar symbols (such as "1" and "1", etc.), and various transformations are performed, and some key prefixes and suffixes are added, such as "bank" and "card" or change the order of the words appearing in the real URL, such as "bankonline" to "onlinebank", etc. All possible URLs include all URLs that may be related to real URLs and are generated after certain transformations. ...

Abstract

The method includes steps: network address generation step in use for generating network address or all network address needed similar to true network address; a step for calculating degree of similarity between web pages is in use for calculating degree of similarity between possible similar web page and true web page in order to determine whether it is similarity between possible similar web page and true web page; the possible similar web page is web page corresponding to similar network address generated, and the true web page is a web page corresponding to true network address; a alarming step in use for carrying out alarming operation when similar web page appears. Degree of similarity of web pages is calculated through comparing structures and / or styles and / or contents and / or colors and / or fonts of web pages. Further, detailed similarity and style similarity of web pages are calculated. Integral similarity is weighted mean of detailed similarity and style similarity.
