The Application of XML and Web service on Database Security Control Mode in Pervasive Space

When database resources being integrated into the pervasive environment, the universal key problem to solve is access mechanisms of database security. The database security mechanisms have already been firmed in the database system. When more flexible security schemas to adapt to the pervasive environment are needed, the database system could solve the problem above insufficiently by itself. We could make full uses of the advantages of XML and Web service to deal with the problem above. This paper proposes such flexible a database security model using XML as the middleware and Web service as the communication tool in different platforms in pervasive environment that the problems of database security could be solved wonderfully in pervasive environment.
