We introduce the notion of views as a mechanism for securing and providing access control in the context of XML. Research in XML has explored several efficient querying mechanism...
At present, most of the state-of-the-art solutions for XML access controls are either (1) document-level access control techniques that are too limited to support fine-grained sec...
Many existing access controls use node filtering or querying rewriting techniques. These techniques require rather time-consuming processes such as parsing, labeling, pruning and/...

Access control models for XML data can be classified in two major categories: node filtering and query rewriting systems. The first category includes approaches that use access ...
