abstract = "Data federations provide seamless access to multiple
heterogeneous and autonomous data sources pertaining to
a large organization. As each source database defines
its own access control policies for a set of local
identities, enforcing such policies across the
federation becomes a challenge. In this article, we
first consider the problem of translating existing
access control policies defined over source databases
in a manner that allows the original semantics to be
observed while becoming applicable across the entire
data federation. We show that such a translation is
always possible, and provide an algorithm for
automating the translation. We show that verifying
whether a translated policy obeys the semantics of the
original access control policy defined over a source
database is intractable, even under restrictive
scenarios.",
