The paper describes a novel application of a Privilege Management Infrastructure (PMI) to enforce copyright protection in electronic content distribution. The PMI is "global" in nature and thus permits customers to gain access to content on any appropriate device. The use of a PMI also allows delegation of access to content. A unique key encrypting scheme provides increased security over other methods of protecting electronic content.
