ABSTRACT

XML as a simplified dialect of SGML overcomes the limitations of HTML with a fixed set of tags and thereby allows its users to define their own document structures. The existing access control requires DOM trees to be loaded on memory in the process of parsing XML documents to generate the trees. This provides data only corresponding to its users' authority levels by authorizing them to access only the specific items of XML documents when they're searching XML documents. In order to do this, the XML eliminates certain parts of documents which are inaccessible and transmits parts accessible depending on its users' authority levels. In this paper we propose an efficient access control policy.
