Objective Tree

The use of Digital Rights Management (DRM) systems involves several stakeholders, such as the content provider, the license provider, and the user, each having their own incentives to use the system. Proper use of the system implies that these incentives can only be met if certain security requirements are fulfilled. Much attention in literature has been devoted to specific security aspects of DRM systems. The contributions of this chapter consist of deriving a systematic overview of core security requirements for DRM systems. This chapter conducts a stakeholder analysis, gives an objective tree for each relevant stakeholder, and develops a simple, generic conceptual model to arrive at the set of core security requirements.

Rights Expression Languages

Rights expression languages (RELs) form a central component of digital rights management (DRM) systems. The process of development of RELs transforms the rights requirements to a formal language ready to be used in DRM systems. Decisions regarding the design of the conceptual model, syntax, semantics, and other such properties of the language, affect not only each other, but also the integration of the language in DRM systems, and the design of DRM system as a whole. This chapter provides a detailed analysis of each step of this process and the tradeoffs involved that not only affect the properties of the REL, but also the DRM system using that REL.

Insight Into

Digital Rights Management (DRM) is an issue of controlling and managing digital rights over intellectual property. It has recently broadened its scope from being merely a content protection concern to description, identification, trading, protection, monitoring and tracking of rights over tangible or intangible assets. In our study we found out an essential problem of the domain: lack of models on an appropriate level of abstraction needed to support research and system development. Modelling, identifying and describing the core entities enable the rights management functionalities. This chapter contributes in recognizing the principal entities and providing detailed description on current identification and description matters and solutions. Our analysis results in the remark of distinguishing the evolution stages of digital content and separating the different offers and agreements through which the rights are traded between the value chain participants. Based on the depiction of the domain model, this chapter additionally gives insight into the future trends and issues on the DRM domain.
