摘要

The method involves authenticating an authentication server (105) by token and vice versa for each of web pages (106) requested by user (100), by executing a control script (107) e.g. java script, in a computer (102), where an authentication system is connected to the computer for authenticating the user after the authentication server is connected to an Internet network (101). The control script is either recorded in the computer or included in a web page transmitted by a web server (103), where the script is recorded in the computer when the computer receives the web page.
