Abstract: A method and a system for real-time analyzing and processing data over the internet are proposed, that can real-time analyze and process data relating to a user's browsing behavior in terms of the contents of a web site browsed by the user, user's accounts used in other web sites and personal information such as e-mail account or identification number, recorded by the web site browsed by the user, so as to display in a browser of the user's computer device a web site different from the web site browsed by the user in response to the analyzed and processed data. In this case, while the user's browser is linked to the foregoing system through the internet, the system can be real-time responsive to the user's browsing behavior for providing the user with different web sites preferred by the user.
