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. A first terminal for accessing a service, comprising:

a communications interface configured to exchange data with a second terminal and a verifying system, wherein

the communications interface configured to receive, from the second terminal, an authorization message indicating that the first terminal is authorized to access the service; and

the communications interface configured to transmit, to the verifying system, a message for utilization of the service based on the received authorization message, and

the message for utilization is based on a message received by the second terminal from the verifying system indicating that the first terminal is authorized to access the service.

2. The terminal of claim 1, further comprising:

a memory configured to store additional information used for utilization of the service,

wherein the message for utilization is based on the additional information.
