A view based security framework for XML

As science communities and commercial organisations increasingly exploit XML as a means of exchanging and disseminating information, the selective exposure of information in XML has become an important issue. In this paper we present a novel XML security framework developed to enforce a generic, flexible access-control mechanism for XML data management, which supports efficient and secure query access, without revealing sensitive information to unauthorized users. Major components underlying the framework are discussed and the current status of a reference implemenation is reported.
