Abstract

As the increasing of data exchange technology, the security in publishing views has been paid more attention to. Inspired by the knowledge of probabilistic database, this paper erects a probability model of security deciding in publishing views, and it gives the formularized definition of publishing views, private information, prior knowledge and so on. Then a new deciding theorem based on entropy is provided, and introduce techniques for measuring the magnitude of information disclosures in publishing view.
