To facilitate the compliance with different privacy policies when several parts of an organization or different enterprises cooperate, it is crucial to have tools at hand that allow for a practical management of varying privacy requirements. We propose an algebra providing various types of operators for composing and restricting enterprise privacy policies like conjunction, disjunction, and scoping, together with its formal semantics. We base our work on a superset of the syntax and semantics of IBM’s Enterprise Privacy Authorization Language (EPAL), which recently has been submitted to W3C for standardization. However, a detailed analysis of the expressiveness of EPAL reveals that, somewhat surprisingly, EPAL is not closed under conjunction and disjunction. To circumvent this problem, we identified the subset of well-founded privacy polici...
