A bitmap-based access control for restricted views of XML documents

The information on the web is growing at a very fast pace. In this ever-accumulating data, the volume of information represented in XML format is on the rise in recent times. An organization that puts forth its information on the web in XML format has several issues to take into account such as limiting the view of intended audience to only relevant portions of the documents. To address this problem, we propose the concept of “Restricted views” to implement security in XML documents. This could be accomplished by defining “Access control” for the users trying to access the system. In this paper, we describe a bitmap-based approach to represent access control in XML documents. We also introduce a new three-dimensional bitmap called security cube, which efficiently represents access control on XML documents at their finest level of granularity.
