METHOD AND SYSTEM FOR DISCOVERING SERVICE IN MULTI DOMAINS USING IDENTITY FEDERATION

摘要

A method and a system for searching a multi-domain service with identity federation are provided to search all ID services of the user registered to a plurality of domains by federating user ID information when a user is previously registered to other ID providers having trusted relation with a registered ID provider. A user register(110) interchanges the user ID federation information with other trusted ID providers on a multi-domain and registers the user. A service register(120) registers a user ID service requested from the registered user. A service searcher(130) searches the user ID service registered to the ID provider(100) or other ID providers through the user ID federation information.
