Multimedia Security Technologies for Digital Rights Management
Security is a major concern in an increasingly multimedia-defined universe where the Internet serves as an indispensable resource for information and entertainment. Digital Rights Management (DRM) is the technology by which network systems protect and provide access to critical and time-sensitive copyrighted material and/or personal information. This book equips savvy technology professionals and their aspiring collegiate protégés with the latest technologies, strategies and methodologies needed to successfully thwart off those who thrive on security holes and weaknesses. Filled with sample application scenarios and algorithms, this book provides an in-depth examination of present and future field technologies including encryption, authentication, copy control, tagging, tracing, conditional access and media identification. The authors present a diversified blend of theory and practice and focus on the constantly changing developments in multimedia applications thus providing an admirably comprehensive book. * Discusses state-of-the-art multimedia authentication and fingerprinting techniques * Presents several practical methodologies from industry, including broadcast encryption, digital media forensics and 3D mesh watermarking * Focuses on the need for security in multimedia applications found on computer networks, cell phones and emerging mobile computing devices
Issues and Challenges in Securing Interoperability of DRM Systems in the Digital Music Market
In the digital music market (and accompanying digital players), use of different digital rights management (DRM) systems, have effectively locked-in consumers to proprietary technologies of respective companies. Currently, no single DRM standard exists for digital music, therefore, music purchased from one competitor may not be compatible with another competitor's jukeboxsoftware or digital player. There is little incentive for leading competitors to license their technology or provide support for other technologies to enable interoperability of different technologies. Consequently, consumers purchasing from such competitors in-effect become locked into their proprietary technology and its accompanying DRM systems. This paper examines the consequences of such market behaviour focusing on the most popular music store iTunes (owned by Apple), its dominance in the industry and the implications of Apple's decision not to open its FairPlay DRM scheme that controls all music purchased from iTunes. It discusses the attempt by RealNetworks to secure interoperability with Apple's FairPlay scheme and the resultant response of Apple. Finally, it examines the potential benefits, problems and legal issues raised by the actions of RealNetworks and argues for interoperability.

The content industries consider Digital Rights Management (DRM) to contend with unauthorized downloading of copyrighted material, a practice that costs artists and distributors massively in lost revenue. Based on two conferences that brought together high-profile specialists in this area - scientists, lawyers, academics, and business practitioners - this book presents a broad, well-balanced, and objective approach that covers the entire DRM spectrum. Reflecting the interdisciplinary nature of the field, the book is structured using three different perspectives that cover the technical, legal, and business issues. This monograph-like anthology is the first consolidated book on this young topic.
