Digital rights management systems are required to provide security and accountability without violating the privacy of the entities involved. However, achieving privacy along with accountability in the same framework is hard as these attributes are mutually contradictory. Thus, most of the current digital rights management systems rely on trusted third parties to provide privacy to the entities involved. However, a trusted third party can become malicious and break the privacy protection of the entities in the system. Hence, in this paper, we propose a novel privacy preserving content distribution mechanism for digital rights management without relying on the trusted third party assumption. We use simple primitives such as blind decryption and one way hash chain to avoid the trusted third party assumption. We prove that our scheme is not prone to the "oracle problem" of the blind decryption mechanism. The proposed mechanism supports access control without degrading user's privacy as well as allows revocation of even malicious users without violating their privacy.Index Terms-Accountability, blind decryption, digital rights management (DRM), hash chain, privacy.

We propose LicenseScript, a language for digital rights management (DRM) based on multiset rewriting and logic programming. LicenseScript enjoys a precise syntax and semantics, and it is rich enough to embed other rights expression languages (REL). We show that LicenseScript is expressive and flexible by exploring several application domains representing different aspects of DRM. We present an implementation. Finally, we extend the core of the language to account for multiple devices in authorized domains.

Abstract. Content protection mechanisms are intended to enforce the usage rights on the content. These usage rights are carried by a license. Sometimes, a license even carries the key that is used to unlock the protected content. Unfortunately, license protection is difficult, yet it is important for digital rights management (DRM). Not many license protection schemes are available, and most if not all are proprietary. In this paper, we present a license protection scheme, which exploits tamper-resistant cryptographic hardware. The confidentiality and integrity of the license or parts thereof can be assured with our protection scheme. In addition, the keys to unlock the protected content are always protected and stored securely as part of the license. We verifiy secrecy and authentication aspects of one of our protocols. We implement the scheme in a prototype to assess the performance.
