Abstract
An authentication system includes service providing systems, a global ID platform, and a terminal device owned by a user. The first service providing system includes a first authentication server and a first back-end server. The first back-end server provides a first service. The second service providing system includes a second authentication server and a second back-end server. The second back-end server provides a third service. The user is a member of the first service and has a user ID of the first service. When the user requests global login to the third service, the global ID platform relays the request from the second authentication server to the first authentication server and relays an authentication result, returned by the first authentication server for the request, from the first authentication server to the second authentication server.
