PURPOSE: A method and a system for authenticating a user for sub locations of a network location are provided to supply a cookie for user authentication about a sub location of a network location, thereby enabling a hacker to pretend as a user only about the same sub location that the user with ill will already accesses even though a cookie is stolen from the user with ill will. CONSTITUTION: A method for authenticating a user for at least sub locations of a network address comprises the following steps. If a cookie is effective, the second cookie for user authentication about the first sub location of a network address is provided to a user computer(308). When a computer attempts to access a network address after the first attempt, the first cookie is made effective to authenticate a user about the network address. When the computer attempts to access the first sub location after the first attempt, the second cookie is obtained and made effective from a computer to authenticate a user about the first sub location of the network address. |
