AUTOMATIC LOG IN SYSTEM AND METHOD

摘要

An integrated automatic login system and a method are provided to enable a user to automatically register to all cooperated sites with one-click without inputting personal information by using a personal certificate and enable the user to automatically log in to the cooperated sites from a main site with one-click. An encryption/authentication server(300) provides a registration service page for receiving profile information from the user. If login and profile information are received from the user through the registration service page, the encryption/authentication server encrypts and stores the profile information to a member database by matching with the login information. When a member identification request is received from a cooperated website server(400) with a user ID, the encryption/authentication server checks whether the user is registered by using the user ID and returns a signal for authenticating the registered user if the user is registered. The cooperated website server provides a login information input window including an identification button for transmitting the information inputted from the user to the encryption/authentication server if the user clicks the button.
