title = "On flexible modeling of history-based access control policies for XML documents",
abstract = "Many scenarios require models for access control which consider former accesses to permit or deny access. One such model is the Chinese Wall model (CWM) which was designed to prevent the misuse of insider knowledge in the consulting business. In this paper, we show that our model for history-based access control provides a flexible and expressive method to define access depending on histories, which contain information about former accesses. We demonstrate this by modeling the policies of the CWM in a way that avoids the unnecessary restrictions of the original CWM.",
