Abstract

An object is to provide a service providing method capable of curbing rise of cost A service providing method according to the present invention is one for providing services A and B, which authenticates a user of an authentication requesting terminal in order to make service A available to the user and which determines whether service B is available to the user, in a state in which the user is authenticated about service A. When service B is determined to be available, a permission message is stored and a permission response based on the permission message for utilization of service B is transmitted to the authentication requesting terminal. Then the permission message on which a utilization request message from a service utilizing terminal is based, is verified, and, if it is in an available status, the service utilizing terminal is permitted to utilize service B. The use of the authentication result on service A obviates a need for provision of new authentication means for service B, so as to lead to reduction of cost.

Claims

1. An authentication requesting terminal permitted to utilize a first service provided by a service verifying system and configured to execute authentication for utilization of the first service, the authentication requesting terminal comprising:

an authentication information storing module configured to store authentication information for utilization of the first service;

first message transmitting module configured to transmit a message based on the authentication information in the authentication information storing module and according to an authentication method;

other service utilization request transmitting module configured to transmit a utilization request for utilization of a second service when the first service is available;

permission response receiving module configured to receive a permission response based on a permission message, the permission response based on available area information of the second service; and

a communication device configured to access at least one of the first and second services based on at least one of the authentication information and the permission message.

2. The authentication requesting terminal according to claim 1, wherein the permission response receiving module receives a permission response further based on available area information of the second service.

3. The authentication requesting terminal according to claim 1, wherein the permission response receiving module receives a permission response further based on available time information of the second service.
