Anti-counterfeiting method for web page

The invention provides an anti-counterfeiting method for a web page. The method comprises the following steps of: changing the dynamic web page in a website into a static web page, and embedding a concealed digital signature into the web page; when a user browses the web page, automatically loading a browser plug-in provided by the website, and inputting personal information during installing the plug-in; detecting whether the web page is from the website, detecting the digital signature of the web page from the website and judging whether the web page is the original web page by the plug-in; directly intercepting the non-original web page and giving an alarm by the plug-in; displaying the personal information input by the user at the same time of displaying the original web page on a browser; and when the user will log in the website and discovers the personal information is not correctly displayed, determining that the current website is a counterfeited angling website. By the method, the problem that most methods depending on known rule bases lack defense capacity on novel angling attacks and latest angling websites in the prior art is solved.
