As documents containing sensitive information are exchanged over the Internet, access control of XML documents is becoming important. Access control policies can specify fine-grained rules to documents, but policies sometimes become redundant, as documents are restructured or combined during exchange. In this paper, we consider a new approach of optimizing access control policies, by extracting distribution information of given authorization values within XML data, The extracted information is called a global policy tree, and it can be utilized for minimizing the total size of policies as well as efficient query processing, We present a linear-time algorithm for minimizing policies utilizing global policy trees, and our evaluation results show significant improvement over existing work.
