Synopsis
With a preface by Ton Kalker.
Informed Watermarking is an essential tool for both academic and professional researchers working in the areas of multimedia security, information embedding, and communication. Theory and practice are linked, particularly in the area of multi-user communication.
From the Preface: Watermarking has become a more mature discipline with proper foundation in both signal processing and information theory. We can truly say that we are in the era of "second generation" watermarking. This book is first in addressing watermarking problems in terms of second-generation insights. It provides a complete overview of the most important results on capacity and security. The Costa scheme, and in particular a simpler version of it, the Scalar Costa scheme, is studied in great detail. An important result of this book is that it is possible to approach the Shannon limit within a few decibels in a practical system. These results are verified on real-world data, not only the classical category of images, but also on chemical structure sets. Inspired by the work of Moulin and O'Sullivan, this book also addresses security aspects by studying AGWN attacks in terms of game theory.
"The authors of Informed Watermarking give a well-written exposé of how watermarking came of age, where we are now, and what to expect in the future. It is my expectation that this book will be a standard reference on second-generation watermarking for the years to come."

Eggers (University of Erlangen) and Girod (Stanford University) overview several approaches to digital watermarking, and develop a suboptimal practical communication scheme based on Costa's scheme, called the scalar Costa scheme. The approach involves embedding information into independent identically distributed data and attacks by additive white Gaussian noise. The performance limits of digital watermarking facing liner filtering and additive noise attacks are investigated. The final chapter applies the concepts to the digital watermarking of 3D atomic coordinates in chemical structures and digital images. Annotation c. Book News, Inc., Portland, OR
