The method includes the steps that the security plug-ins are initialized and installed; the security plug-ins and important web pages are registered, and registration information is stored in the
verification table of the
server side; the browser starts the security plug-ins, and whether the kernel of the browser and the security plug-ins are corrected or not are verified; abstract information of DOM trees of the important web pages are calculated, and webpage verification requests are sent to the
server side; the
server side receives the webpage verification requests sent by the security plug-ins and extracts registered corresponding webpage abstract information, the registered corresponding webpage abstract information is verified, and verification feedback information is sent back; the browser is driven to continue executing and displaying web pages or to stop having access to
web page operations according to the verification feedback information. Accordingly, safety protection is provided for accessing the important web pages, and data and fund security of users in network
