Abstract
An authorization server to issue an access token for accessing a resource provided by a resource server performs operations. A client receives an issuance request having a predetermined parameter identifying a type of access token to be issued. Based on the predetermined parameter, one of a first type or second type of access token to be verified by the resource server is issued. The first type of access token or the second type of access token is transmitted to the client from which the issuance request was received. The second type of access token is verified at the authorization server by receipt of a verification request received together with the second type of access token from the resource server. The received verification request is transmitted from the resource server based on the resource server determining that a request for service from the client includes the second type of access token.
