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 studying towards an effective and practical system. Multimedia Security: Steganography and Digital Watermarking Techniques for Protection of Intellectual Property explores the myriad of issues regarding multimedia security. This book covers various issues, 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.
In this digital era, the ubiquitous network environment has promoted the rapid delivery of digital multimedia data. Users are eager to enjoy the convenience and advantages that networks have provided. Meanwhile, users are eager to share various media information in a rather cheap way without awareness of possibly violating copyrights. In view of these, digital watermarking technologies have been recognized as a helpful way in dealing with the copyright protection problem in the past decade. Although digital watermarking still faces some challenging difficulties for practical uses, there are no other techniques that are ready to substitute it. In order to push ahead with the development of digital watermarking technologies, the goal of this book is to collect both comprehensive issues and survey papers in this field so that readers can easily understand state of the art in multimedia security, and the challenging issues and possible solutions. In particular, the authors that contribute to this book have been well known in the related fields. In addition to the invited chapters, the other chapters are selected from a strict review process. In fact, the acceptance rate is lower than 50%.
There are eight chapters contained in this book. The first two chapters provide a general survey of digital watermarking technologies. In Chapter I, an extensive literature review of the multimedia copyright protection is thoroughly provided. It presents a universal review and background about the watermarking definition, concept and the main contributions in this field. Chapter II focuses on the discussions of perceptual properties in image watermarking. In this chapter, a detailed description of the main phenomena regulating the HVS will be given and the exploitation of these concepts in a data hiding system will be considered. Then, some limits of classical HVS models will be highlighted and some possible solutions to get around these problems pointed out. Finally, a complete mask building procedure, as a possible exploitation of HVS characteristics for perceptual data hiding in still images will be described.
