Integrating access control mechanism with EXEL labeling scheme for XML document updating

Abstract

Recently, an urgent need for XML access control mechanism over World Wide Web has been felt. Moreover, an efficient dynamic labeling scheme is required in order to eliminate the re-labeling process of existing XML nodes during XML document updating. However, the previous research on access control mechanisms for XML documents has not addressed the issue of integrating access control with a dynamic labeling scheme. In this paper, we propose an XML access control mechanism integrated with EXEL encoding and labeling scheme to eliminate the re-labeling process for updating the well-formed XML documents. The key idea is to regard an authorization as a query condition to be satisfied. Therefore, the benefit of speeding up searching and querying processes is obtained by employing such a labeling scheme in our proposed access control mechanism. © 2011 Springer-Verlag.
