    This report – representing one of three case studies that are part of a transatlantic research project aimed at exploring the potential relation between ICT Interoperability and eInnovation – examines issues surrounding DRM interoperability within the context of music content. Recognizing that interoperability will likely be defined differently by different stakeholders, we begin by establishing a rough, holistic working definition of interoperability and then assess the implementation of DRM in the music content market and associated problems with regard to interoperability. We then go on to explore the technological, market, and legal environments in their relation to and impact upon the achievement of interoperable DRM systems. In part 2, we analyze potential benefits and drawbacks of an interoperable DRM environment for the music content market. We then evaluate both private and public-initiated approaches towards the accomplishment of interoperability using a series of qualitative benchmarks. Lastly, we conclude by summing up the merits and demerits of the various approaches. Our findings lead us to surmise that normative considerations weigh in favor of greater interoperability in general. The challenge of determining the optimal level of interoperability and the best approach for attaining it, however, points toward consideration of a number of complex factors. We conclude that the best way to determine the optimal level of interoperability and means of accomplishing it is to rely upon economic-based assessments on a case-by-case basis

    Interoperability mechanisms for registration and authentication on different open DRM platforms

    The DRM interoperability problem is a very complex problem. Even big software companies have already admitted that DRM as it is today is too complex ? complex for end-users, complex for content providers and complex for content handling devices manufactures. There are different approaches to deal with this problem and there are different levels to address the problem. This article addresses the DRM interoperability issues from a security point of view, and as an example the authors take two open-specification DRM architectures ? MIPAMS and OpenSDRM ? to identify a strategy to interoperate some of the basic security mechanisms. In this article the authors will concentrate in the DRM components and user’s registration, authentication and verification process and will derive a mechanism to handle and support both

    System Design of Internet-of-Things for Residential Smart Grid

    Internet-of-Things (IoTs) envisions to integrate, coordinate, communicate, and collaborate real-world objects in order to perform daily tasks in a more intelligent and efficient manner. To comprehend this vision, this paper studies the design of a large scale IoT system for smart grid application, which constitutes a large number of home users and has the requirement of fast response time. In particular, we focus on the messaging protocol of a universal IoT home gateway, where our cloud enabled system consists of a backend server, unified home gateway (UHG) at the end users, and user interface for mobile devices. We discuss the features of such IoT system to support a large scale deployment with a UHG and real-time residential smart grid applications. Based on the requirements, we design an IoT system using the XMPP protocol, and implemented in a testbed for energy management applications. To show the effectiveness of the designed testbed, we present some results using the proposed IoT architecture.Comment: 10 pages, 6 figures, journal pape

    Digital object rights management: Interoperable client-side DRM middleware

    Get PDF
    In a more and more interconnected world where the available bandwidths are increasing at a pace hard to imagine some time ago, multimedia e-content distribution over digital networks has become one of the biggest available services online. Powered not only by the network high availability but also by the emergence of new compression techniques and digital content consumer device, digital content is gaining momentum. However the same factors that power this emergence are also causing some problems, specially related with the digital content IPR management and protection. These problems are being handled employing DRM - Digital Rights Management technology which lack interoperability. This paper presents and discusses a solution that provides interoperability to DRM-protected content through the employment of a client-side DRM middleware layer. This middleware layer sits at the client-side of a broader DRM system (called DoRM) providing the necessary mechanisms to achieve interoperability between the different digital content rendering applications that the users possesses.info:eu-repo/semantics/acceptedVersio

    Digital Rights Management and Consumer Acceptability: A Multi-Disciplinary Discussion of Consumer Concerns and Expectations

    Get PDF
    The INDICARE project – the Informed Dialogue about Consumer Acceptability of DRM Solutions in Europe – has been set up to raise awareness about consumer and user issues of Digital Rights Management (DRM) solutions. One of the main goals of the INDICARE project is to contribute to the consensus-building among multiple players with heterogeneous interests in the digital environment. To promote this process and to contribute to the creation of a common level of understanding is the aim of the present report. It provides an overview of consumer concerns and expectations regarding DRMs, and discusses the findings from a social, legal, technical and business perspective. A general overview of the existing EC initiatives shows that questions of consumer acceptability of DRM have only recently begun to draw wider attention. A review of the relevant statements, studies and reports confirms that awareness of consumer concerns is still at a low level. Five major categories of concerns have been distinguished so far: (1) fair conditions of use and access to digital content, (2) privacy, (3) interoperability, (4) transparency and (5) various aspects of consumer friendliness. From the legal point of view, many of the identified issues go beyond the scope of copyright law, i.e. the field of law where DRM was traditionally discussed. Often they are a matter of general or sector-specific consumer protection law. Furthermore, it is still unclear to what extent technology and an appropriate design of technical solutions can provide an answer to some of the concerns of consumers. One goal of the technical chapter was exactly to highlight some of these technical possibilities. Finally, it is shown that consumer acceptability of DRM is important for the economic success of different business models based on DRM. Fair and responsive DRM design can be a profitable strategy, however DRM-free alternatives do exist too.Digital Rights Management; consumers; Intellectual property; business models

    White Knight or Trojan Horse? The Consequences of Digital Rights Management for Consumers, Firms and Society

    Get PDF
    Due to its ability to solve all main problems associated with digital goods, Digital Rights Management is the favourite option used by companies to tackle piracy. The aim of this article is to discuss the consequences of DRM for consumers, firms and society. The rationales of DRM are discussed and the expected benefits for firms are presented.. In contrast, consumers are shown to be likely to see few benefits in DRM. This article demonstrates that even a standard DRM system is unlikely to improve social welfare. The article concludes with some public policy recommendations.Digital Rights Management, Digital Goods, Piracy, Excludability, Durability, Sampling.
