Intellectual property owners who exploit new ways of reproducing, distributing, and marketing their creations digitally must also protect them from piracy. Multimedia Security Handbook addresses multiple issues related to the protection of digital media, including audio, image, and video content. This volume examines leading-edge multimedia security concepts including protection architectures, encryption, watermarking, fingerprinting, authentication, and various applications. Comprinsing 26 chapters, the Handbook begins by introducing security fundamentals and discussing the vulnerabilities of individual protection schemes. Part II focuses on multimedia encryption, detailing audio, image, and video encryption techniques. Part III examines watermarking techniques, reviewing current and future trends and discussing multidimensional, fragile, and robust watermarks. Part IV covers multimedia data hiding, fingerprinting, and authentication. The text concludes with chapters describing applications of multimedia protection schemes, presenting topics such as application taxonomy, digital rights management, and techniques for adult image filtering. The Handbook offers comprehensive reference material on advanced topics in the field. It delivers invaluable insight for researchers, practitioners, and engineers involved in designing and developing systems that protect digital multimedia content. Features Addresses Multiple issues related to the protection of digital media, including audio, image, and video content, Analyzes techniques such as selective video encryption for real-time requirements, chaos-based encryption, key management, and streaming media protection, Illustrates lossles data hiding scalable image and video authentication, and signature-based media authentication, Explores digital rights management for consumer devices, Reviews the applications, parameters, and requirements of the digital watermarking framework, Examines the vulnerabilities of protection schemes. Book jacket.

The authors give a detailed summary about the fundamentals and the historical background of digital communication. This includes an overview of the encoding principles and algorithms of textual information, audio information, as well as images, graphics, and video in the Internet. Furthermore the fundamentals of computer networking, digital security and cryptography are covered. Thus, the book provides a well-founded access to communication technology of computer networks, the internet and the WWW. Numerous pictures and images, a subject-index and a detailed list of historical personalities including a glossary for each chapter increase the practical benefit of this book that is well suited as well as for undergraduate students as for working practitioners.

With the rapid evolution of multimedia communications, engineers and other professionals are generally forced to hoard a plethora of different texts and journals to maintain a solid grasp on essential ideas and techniques in the field. Wireless Multimedia Communications provides researchers and students with a primary reference to help readers take maximum advantage of current systems and uncover opportunities to propose new and novel protocols, applications, and services. Extract the Essentials of System Design, Analysis, Implementation A complete technical reference, the text condenses the essential topics of core wireless multimedia communication technologies, convergence, QoS, and security that apply to everything from networking to communications systems, signal processing, and security. From extensive existing literature, the authors distill the central tenets and primary methods of analysis, design, and implementation, to reflect the latest technologies and architectural concepts. The book addresses emerging challenges to inform the system standardization process and help engineers combat the high error rates and stringent delay constraints that remain a significant challenge to various applications and services. Keep Pace with Detailed Techniques to Optimize Technology The authors identify causes of information loss in point-to-point signal transmission through wireless channels, and then they discuss techniques to minimize that loss. They use examples that illustrate the differences in implementing various systems, ranging from cellular voice telephony to wireless Internet access. Each chapter has been carefully organized with the latest information to serve dual purposes as an easy-to-reference guide for professionals and as a principal text for senior-level university students.

This book presents a state-of-the art review of current perspectives on Communications and Multimedia Security. It contains the Proceedings of the 3rd Joint Working Conference of IFIP TC6 and TC11, arranged by the International Federation for Information Processing and held in Athens, Greece in September 1997. The book aims to cover the subject of Communications and Multimedia Systems Security, as fully as possible. It constitutes an essential reading for information technology security specialists; computer professionals; communication systems professionals; EDP managers; EDP auditors; managers, researchers and students working on the subject.

Communications and Multimedia Security is an essential reference for both academic and professional researchers in the fields of Communications and Multimedia Security. This state-of-the-art volume presents the proceedings of the Eighth Annual IFIP TC-6 TC-11 Conference on Communications and Multimedia Security, September 2004, in Windermere, UK. The papers presented here represent the very latest developments in security research from leading people in the field. The papers explore a wide variety of subjects including privacy protection and trust negotiation, mobile security, applied cryptography, and security of communication protocols. Of special interest are several papers which addressed security in the Microsoft .Net architecture, and the threats that builders of web service applications need to be aware of. The papers were a result of research sponsored by Microsoft at five European University research centers. This collection will be important not only for multimedia security experts and researchers, but also for all teachers and administrators interested in communications security.

Multimedia security has become a major research topic, yielding numerous academic papers in addition to many watermarking-related companies. In this emerging area, there are many challenging research issues that deserve sustained study towards an effective and practical system. This book explores the myriad of issues regarding multimedia security, including perceptual fidelity analysis, image, audio, and 3D mesh object watermarking, medical watermarking, error detection (authentication) and concealment, fingerprinting, digital signature and digital right management.
