Semantic Generation of Clouds Privacy Policies.

The governance of privacy and personal information on cloud environments is challenging and complex. Usually many regulatory frameworks intervene to reflect diverse privacy wishes from several stakeholders. This includes data owners, data and services providers and also the end users. Focusing mainly on medical domains, this issue is particularly important due to the sensitivity of health related data in international data protection law. It is therefore essential to integrate heterogeneous privacy requirements in a semantic model and rules. Thereafter, overlaps, contradictions and similarities of privacy wishes could be detected and a final access control context would be captured before it is finally mapped to clouds operational policies. This paper describes a ontology-based semantic model of privacy requirements along with a logical formalism for mapping SWRL (Semantic Web Rule Language) privacy rules to a policy language that is implementable on clouds environments namely XACML. The underline implementation requirements for our formalism will be also explained.
