Dynamic Expression of Digital Rights by Rewriting License
ABSTRACT In this paper, we propose a kind of dynamic expression of digital rights by rewriting license for digital rights management based on multiset rewriting and logic programming. Firstly, the essential elements definition is introduced. After that, the execution model is discussion. The final part explores the application model.

Conference Proceeding: Key Challenges in DRM: An Industry Perspective.[show abstract] [hide abstract]
ABSTRACT: The desires for robust digital rights management (DRM) sys- tems are not new to the commercial world. Indeed, industrial research, development and deployment of systems with DRM aspects (most no- tably crude copy-control schemes) have a long history. Yet to date the industry has not seen much commercial success from shipping these sys- tems on top of platforms that support general-purpose computing. There are many factors contributing to this lack of acceptance of current DRM systems, but I see three specific areas of work that are key adoption blockers today and ripe for further academic and commercial research. The lack of a general-purpose rights expression/authorization language, robust trust management engines and attestable trusted computing bases (TCBs) all hamper industrial development and deployment of DRM sys- tems for digital content. In this paper I briefly describe each of these challenges, provide examples of how the industry is approaching each problem, and discuss how the solutions to each one of them are depen- dent on the others.Security and Privacy in Digital Rights Management, ACM CCS-9 Workshop, DRM 2002, Washington, DC, USA, November 18, 2002, Revised Papers; 01/2002
Conference Proceeding: LicenseScript: a novel digital rights language and its semantics[show abstract] [hide abstract]
ABSTRACT: We propose LicenseScript as a new multiset rewriting/logic based language for expressing dynamic conditions of use of digital assets such as music, video or private data. LicenseScript differs from other rights expression languages in that it caters for the intentional but legal manipulation of data. We believe this feature is the answer to providing the flexibility needed to support emerging usage paradigms of digital data. We provide the language with a simple semantics based on traces.Web Delivering of Music, 2003. 2003 WEDELMUSIC. Proceedings. Third International Conference on; 10/2003
