A Mechanism for Federated Identification Services for Public Access Portals Using Access-Cards

This paper discusses an access control mechanism for public Web portals by sharing users´ data from identity providers across organizations boundaries among federated organizations using a lightweight Web-based application framework. Each user can subscribe to a portal and be given an access-card which will be used to identify the subscriber at this particular portal or other portals in collaboration. The framework will also implement single-sign-on for member applications of a federation of portals.
