Abstract :
Most federated identity management systems are limited by users´ ability to choose only one identity provider per service session. A proposed linking service lets users securely link their various identity provider (IdP) accounts, enabling the system to aggregate attributes from multiple authoritative sources automatically without requiring users to authenticate separately to each IdP.
