Efficient Access Control for Secure XML Query Processing in Data Streams

摘要

In this paper, we propose an efficient access control for secure XML query processing method to solve the problems using role-based prime number labeling and XML fragmentation. Recently XML has become an active research area. In particular, the need for an efficient secure access control method of XML data in a ubiquitous data streams environment has become very important. Medical records XML documents have the characteristic of an infinite addition in width rather than in depth because of the increment of patients. But the role-based prime number labeling method can fully manage the increase in the size of documents and can minimize the maintenance cost caused by dynamic changes. We have shown that our approach is an efficient and secure through experiments.
