A privacy preserving assertion based policy language for federation systems
To address these deficiencies we propose an extension to an existing assertion based policy language. More specifically, we provide a new set of assertions to define the privacy related properties of a federation system. We extend the com-mon definition of privacy preference policies with obligation preferences. Finally, we illustrate how the proposed framework is realized among service providers to ensure proper enforcement of privacy policies and obligations.
