The 1st International Workshop on Digital Watermarking (IWDW), the con- rence covering all aspects of digital watermarking, was held at the Hotel Riviera situated along the beautiful Han River in Seoul, Korea from November 21 to 22, 2002. These proceedings contain 21 papers that were accepted for presentation at the conference. These papers were selected from 67 submissions including 3 invited papers. They went through a thorough review process by the Program Committee and were selected on the basis of excellence and novelty. The following is a brief description of the history of this conference and - viewing process: In August 2001 some members of the Special Interest Group on Multimedia Protection (SIGMP) of the Korea Institute of Information Security and Cryptology (KIISC) agreed to create the IWDW. In November 2001 we set up a Program Committee and solicited papers while asking Springer-Verlag to publish the proceedings of the workshop in their Lecture Notes in Computer Science series. In July 2002 we received 64 submissions from 14 countries using Microsoft’s conference management site (http://cmt. research. microsoft. com/ iwdw2002/). Each submission was assigned a number automatically by the c- ference management tool and the paper was sent to the Program Committee members for their review. We also encouraged di?erent sets of experts to join for fair reviews.

This book constitutes the thoroughly refereed post-proceedings of the Third International Workshop on Digital Watermarking, IWDW 2004, held in Seoul, Korea in October/November 2004. The 22 revised full papers presented together with 3 invited papers were carefully selected from over 60 submissions during two rounds of reviewing and improvement. The papers are organized in topical sections on systems, theory, authentication and steganography, cryptography, and methods.

This book constitutes the thoroughly refereed post-conference proceedings of the 7th International Workshop on Digital Watermarking, IWDW 2008, held in Busan, Korea, in November 2008. The 36 regular papers included in the volume were carefully reviewed and selected from 62 submissions. Areas of interest to the conference are mathematical modeling of embedding and detection; information theoretic, stochastic aspects of data hiding; security issues, including attacks and counter-attacks; combination of data hiding and cryptography; optimum watermark detection and reliable recovery; estimation of watermark capacity; channel coding techniques for watermarking; large-scale experimental tests and benchmarking; new statistical and perceptual models of content; reversible data hiding; data hiding in special media; data hiding and authentication; steganography and steganalysis; data forensics; copyright protection, DRM, and forensic watermarking; and visual cryptography.

This book deals with digital watermarking, which is defined by the authors of this book as the art of hiding auxiliary information in digital data in a secure, robust and imperceptible fashion. Digital watermarking as a topic has a long history, but before 1995 publications in scientific literature were almost absent. From 1995 onwards however the number of publications on watermarking has been steadily increasing. Today a number of workshops and conferences on this topic exist; also a number of scientific journals on watermarking have been published. This renewed scientific interest in digital watermarking has led very quickly to industrial interest, as well. In 1996 the Copy Protection Technical Working Group, a voluntary consortium consisting of the movie industry, the IT industry and the consumer electronics industry, issued a call for watermarking technologies for the purpose of copy protection of DVD-Video. A few years later the Secure Digital Music Initiative issued a similar call, in this case focusing on copy protection of digital music. These two efforts have been only partially successful: copy protection based on digital watermarking is not (yet) implemented on a large scale in any type of consumer device. This current "failure" of watermarking, to live up to its expectations, finds its cause in a large number of reasons, ranging from legal considerations and system aspects to the relative immaturity of watermarking as a technology.

This book constitutes the refereed proceedings of the 5th International Workshop on Digital Watermarking Secure Data Management, IWDW 2006, held in Jeju Island, Korea in November 2006. The 34 revised full papers presented together with 3 invited lectures cover both theoretical and practical issues in digital watermarking.

We are happy to present to you the proceedings of the 2nd International Workshop on Digital Watermarking, IWDW 2003. Since its modern re-appearance in the academic community in the early 1990s, great progress has been made in understanding both the capabilities and the weaknesses of digital watermarking. On the theoretical side, we all are now well aware of the fact that digital waterma- ing is best viewed as a form of communication using side information. In the case of digital watermarking the side information in question is the document to be wat- marked. This insight has led to a better understanding of the limits of the capacity and robustness of digital watermarking algorithms. It has also led to new and improved watermarking algorithms, both in terms of capacity and imperceptibility. Similarly, the role of human perception, and models thereof, has been greatly enhanced in the study and design of digital watermarking algorithms and systems. On the practical side, applications of watermarking are not yet abundant. The original euphoria on the role of digital watermarking in copy protection and copyright prot- tion has not resulted in widespread usage in practical systems. With hindsight, a n- ber of reasons can be given for this lack of practical applications.

This collection of books brings some of the latest developments in the field of watermarking. Researchers from varied background and expertise propose a remarkable collection of chapters to render this work an important piece of scientific research. The chapters deal with a gamut of fields where watermarking can be used to encode copyright information. The work also presents a wide array of algorithms ranging from intelligent bit replacement to more traditional methods like ICA. The current work is split into two books. Book one is more traditional in its approach dealing mostly with image watermarking applications. Book two deals with audio watermarking and describes an array of chapters on performance analysis of algorithms.

This volume constitutes the proceedings of the 19th International Workshop on Digital Forensics and Watermarking, IWDW 2020, held in Melbourne, VIC, Australia, in November 2020. The 20 full papers in this volume were carefully reviewed and selected from 43 submissions. They cover topics such as: novel research, development and application of digital watermarking and forensics techniques for multimedia security.

The rapid growth of the Internet has fueled the demand for enhanced watermarking and data hiding technologies and has stimulated research into new ways to implement watermarking systems in the real world. This book presents the fundamental principles of watermarking system design and discusses state-of-the-art technologies in information concealment and recovery. It highlights the requirements and challenges of applications in security, image/video indexing, hidden communications, image captioning, and transmission error recovery and concealment. It explains the foundations of digital watermarking technologies, and offers an understanding of new approaches and applications, and lays the groundwork for future developments in the field.

This book constitutes the thoroughly refereed post-conference proceedings of the 13th International Workshop on Digital-Forensics and Watermarking, IWDW 2014, held in Taipei, Taiwan, during October 2014. The 32 full and 14 poster papers, presented together with 1 keynote speech, were carefully reviewed and selected from 79 submissions. The papers are organized in topical sections on forensics; watermarking; reversible data hiding; visual cryptography; and steganography and steganalysis.
