 Chapter 1 introduces the subject of DRM, discusses a number of topics that identify the importance of rights management technologies, and shares some insight about the future.Chapter 2 offers an overview of the general technology structure and capabilities of aDRMsystem, and presents a flexible, extensible reference model that may be used to characterize current and emerging DRM systems. Chapter 3 discusses the importance of interoperability and standardization, and how media value-chains can change thanks to interoperableDRMspecifications which support traditional rights and usages, and illustrates a toolkit approach to interoperable DRM. Chapter 4 presents the fundamentals of multimedia encryption, including cryptographic primitives, application scenarios and design requirements, and an overview of some typical multimedia encryption schemes. Chapter 5 presents the fundamentals of multimedia authentication, including cryptographic primitives, design requirements of multimedia applications, and an overview of some popular approaches. Chapter 6 presents the fundamentals of conditional access systems in cable, satellite, and terrestrial distribution; digital rights management systems on the Internet, and the protection in digital home networks. Chapter 7 provides an overview of the digital watermarking technologies, including applications, design considerations, tools and mathematical background, and latest development. Chapter 8 introduces biometric authentication, and highlights its characteristics as pertained to its application to the digital rights management problem. Chapter 9 analyzes the security requirements and architectures for multimedia distribution and introduces the general concept of format-compliant content protection to address both content adaptation and end-to-end security. Chapter 10 addresses secure scalable streaming and secure transcoding, and shows that by co-designing the compression, encryption, and packetization operations, one can enable streaming and mid-network transcoding to be performed without requiring decryption, i.e., one can simultaneously provide end-to-end security and mid-network transcoding. Chapter 11 presents an overview of scalable encryption and multi-access encryption and key schemes for DRM and other multimedia applications. Chapter 12 introduces broadcast encryption, a relatively recent development in cryptography, and discusses its interesting advantages as a key management scheme for content protection. Chapter 13 addresses the practical problem of tracing the users (traitors) who instrument their devices and illegally resell the pirated copies by redistributing the content or the decryption keys on the Internet. Chapter 14 features steganalysis, the counterpart of steganography, that aims to detect the presence of hidden data. Chapter 15 reviews an emerging research area - the passive-blind image forensics, which addresses image forgery detection and image source identification. Chapter 16 addresses prevention of unauthorized use of the motion picture content in digital cinema. Standardization efforts, goals and an example security system are presented. Chapter 17 presents an overview of activities of a number of standards organizations involved in developingDRMstandards, such asMPEG,OMA, Coral, DMP, ISMA, and AACS, and provides a quick-reference list to many others. Chapter 18 provides an in-depth discussion and analysis of the Digital Millennium Copyright Act and its social and technological implications.
