Secure Semantics based Data Sharing in XML Web Services

In this research work we are working on removing the dependency of XML access control models on the syntactic representation of the XML trees. We propose a semantics-based data sharing approach, expressing XML access control on RDF ontologies that describe the XML documents. The semantics based model transforms the authorizations on the RDF ontologies to the syntactic representation of the access control permissions on the actual XML instances. Our method supports the uniform enforcement of an authentication model on syntactically different but semantically equivalent XML documents, which can be compared for authorizations inconsistency.
