PROBLEM TO BE SOLVED: To realize offering of the service of desired information by means of one user ID and a password, which are viewed from a user, by receiving a request from the user by a gateway, converting the user ID/password and transmitting them to another information supply server or another gateway. SOLUTION: A gateway 1 transfers a request from a user 7 to another gateway 8 or an information supply server 9 or transmits returned data to the user 7 of a request source. A certification means 3 receives the request from the user 7 and checks the user ID and the password. When checking is OK, a destination conversion means 4 takes out the destination of a service destination, which is requested, and the password from a destination conversion table 6 so as to convert them. A data transmission/reception means 2 receives converted data, receives returned data in response to transmitted data. The destination conversion means 4 inversely converts the destination and returns data which are inversely converted to the user 7 of the request source. |
