The integration of XML data among organizations is essential for providing information infrastructure for global e-services. Secure data sharing and interoperability among cooperating XML systems is a major concern. Role-based access control (RBAC) models appear to be the most attractive solution for providing fine-grained access control on shared XML data among cooperating XML systems. In this paper we propose a dynamic role translation in order to provide secure data sharing among systems while preserving necessary autonomy of each individual system. We address security violation caused by associating roles among XML systems and give our solution.
