A four-layer model for security of digital rights management (original) (raw)
2008, Proceedings of the 8th ACM workshop on Digital rights management - DRM '08
Defining Digital Rights Management (DRM) is a complex task. There is no unique universal definition. There are many legal, economic, functional, and technical definitions. This complexity induces also that there is not one unique modeling of DRM. Each model should help to compare different DRM systems and easily highlight the differences and the similarities between them. One of the weaknesses of the current models is that none puts specifically the focus on the most important characteristics of DRM: protection of content and rights management. We propose a four-layer model that complements traditional ones. Using trust layer, rights management layer, rights enforcement layer, and content protection layer, this model is security oriented. It is suitable to describe any content protections such as DRM, conditional access, copy protection or even pre-recorded content protection systems.

Rights protection of digital content in the DRM environment
2015
In electronic-business settings, content providers produce digital goods/services (such as, games, images, softwares, etc.) which consumers/users wish to purchase. In general, mass-production of digital goods/services is possible if an instance of the goods/services is made available. Digital Rights Management (DRM) mainly considers technological approaches to protect content providers' rights on their original products (also known as, intellectual property) against illegal reproduction of the goods/services (also known as, piracy). Due to the wide range and different types of digital goods, several DRM systems have been studied in the literature. Many existing DRM systems, however, focus on the security of the content provider and often neglect the users' privacy. The problem statement of this thesis is devising DRM systems that protect users' privacy while content provider's security is maintained. To achieve this goal during the life-time of the digital content, w...
DRM's rights protection capability: a review
Proceedings of the International Conference on Computational Science and Information Management (ICoCSIM)2012
Digital Right Management (DRM) is a digital content providers' weapon to protect their intellectual property rights. The use of DRM has been rising in recent years. However, though digital technologies have changed enormously in recent decades, many existing DRM technologies only provide partial solutions to an immense problem and thus are still not effective at combating piracy. Additionally, they fail to maintain fair use and protect users' privacy. This paper provides a literature review on the current state of DRM research and a major problem for the DRM system.
A novel approach to DRM systems
Modern Digital Rights Management (DRM) systems are often developed as web software platforms designed as service oriented architectures composed of a federation of coordinated web entities that play distinct roles and dynamically interact within a trusted environment. Such a design approach requires that trustu relationships have to be dynamically established across multiple and heterogeneous organizational boundaries so as to facilitate an ``on-the-fly'' resource sharing. This introduces non-trivial security architectural requirements concerning with the mechanisms that allow different security realms of web entities to be federated. This paper presents a DRM system developed as a web software platform designed to give a specific support both to the interaction of the web entities involved in the platform and to the development of the trusted relationships among them, in a much more flexible way than before, dynamically and with minimal overheads and shared infrastructure.
Digital Rights Management- Open Issues to Support e-Commerce
In the ear of the information technology and the rapid growth of the Internet access, e-Commerce technologies become very crucial as new and effective ways are needed to manage, transact, distribute, and exploit digital contents (e.g. audio and video). The proliferation of these contents has created a need for Digital Rights Management (DRM) systems. DRM, in addition to other security measures, is essential for the management and the protection of digital property which is the main component of an e-Commerce system. This chapter highlights the need for DRM as a tool facilitating e-Commerce. It also provides the history of developing DRM and the main components of a DRM system. It also gives an overview of the existing DRM system used in e-Commerce systems. It then discuss some open issues in the current DRM system to support consumers' rights, so supporting e-commerce business.
The Digital Rights Management (DRM) systems aim at protecting and enforcing the legal rights associated with the use of digital content distributed on the Internet. Most of such systems use watermarking techniques to implement the content protection. Although the effectiveness of the implemented protection strictly depends on the adopted watermarking techniques, an important role is also played by watermarking protocols. They define the scheme of the interactions that have to take place among the entities involved in the processes of content protection and web-based distribution governed by the DRM systems. This paper presents a DRM system developed as a web software platform to implement the copyright protection of multimedia digital content distributed on the Internet. The DRM system is based on a watermarking protocol previously developed by the authors, and has been designed as a service oriented architecture composed of a federation of coordinated web entities that play distinct roles and interact within a trusted environment.
A DRM Framework for Distributing Digital Contents through the Internet
ETRI Journal, 2003
This paper describes our design of a contents distribution framework that supports transparent distribution of digital contents on the Internet as well as copyright protection of participants in the contents distribution value chain. Copyright protection must ensure that participants in the distribution channel get the royalties due to them and that purchasers use the contents according to usage rules. It must also prevent illegal draining of digital contents. To design a contents distribution framework satisfying the above requirements, we first present four digital contents distribution models. On the basis of the suggested distribution models, we designed a contract system for distribution of royalties among participants in the contents distribution channel, a license mechanism for enforcement of contents usage to purchasers, and both a packaging mechanism and a secure client system for prevention of illegal draining of digital contents.
Comparative Study of Digital Rights Management Systems for Music and Text Files
International Mobile IPR Workshop: Rights Management OF Information Products ON THE Mobile Internet, 2003
Digital Rights Management Systems (DRMS) are seen by content providers as the appropriate tool to, on the one hand, fight piracy and, on the other hand, monetize their assets. Although these systems claim to be very powerful and include multiple protection technologies, there is a lack of understanding about how such systems are currently being implemented and used by content providers.
