Abstract

One of the goals of Digital Rights Management Systems is the provision of a flexible access rights management system to specify and enforce digital rights. Policy-based access control is an important feature of flexible access management systems as it facilitates changes in access control with minimum or no changes to the system it protects. Two prominent policy based access specification models (and languages) are the Policy Core Information Model (PCIM) and the eXtensible Access Control Markup Language (XACML). In this paper we analyze and compare the two specification models for their suitability in building access rights for Digital Rights Management Systems.
