digital right management,privacy-preserving,cloud computing

In this paper, a taxonomy of privacy-preserving approaches employed in digital right management systems is presented. These schemes are classified into two main approaches according to their design philosophy: cryptographic and noncryptographic approaches. Moreover, the pros and cons of the presented approaches are reported and compared in light of different viewpoints. Furthermore, some new directions are highlighted based on the insightful comparison of the existing work. This paper can greatly enhance understanding the basic concepts of security issues and properties in digital right management systems.
