| Popis | This paper proposes a novel method for releasing semantic information between organizations in an identity federation, based on automated trust negotiation between the releasing Identity Provider and the consuming Service Provider. In the negotiation, the Service Provider gradually asks for more and more information about the user, until an authorization decision can be made. The paper also proposes an algorithm for detecting which information needed for a decision is missing in an OWL2 ontology. |
