Digital Watermarking and Steganography | Fundamentals and Techniques | Taylor & Francis GroupYour Account. This book intends to provide a comprehensive overview on different aspects of mechanisms and techniques for information security. It is written for students, researchers, and professionals studying in the field of multimedia security and steganography. Multimedia security and steganography is especially relevant due to the global scale of digital multimedia and the rapid growth of the Internet. Digital watermarking technology can be used to guarantee authenticity and can be applied as proof that the content has not been altered since insertion. Updated techniques and advances in watermarking are explored in this new edition. The combinational spatial and frequency domains watermarking technique provides a new concept of enlarging the embedding capacity of watermarks.

Digital Watermarking and Steganography Fundamentals and Techniques Second Edition by Frank Y. Shih
Chapter 1 introduces the field and distinguishes watermarking from steganography. Fridrich, M. Simon, DWT and DCT and application of Arnold scrambling technique the new watermarking scheme proves to be more robust as it is evident from the experimental result. With combination of conventional and widely used watermarking tecniques such as LSB, J.Summary Every day millions of people capture, transm. Digital Watermarking and Steganography. Kernel Methods for Pattern Analysis. Watermarking is a field of signal processing and pattern recognition that has enjoyed accelerated interest since the mids directly in parallel to the explosive growth of the Internet.

Modern information-hiding techniques conceal the existence of communication. The primary facets of information hiding, also known as data hiding, are payload size, robustness to removal, and imperceptibility of the hidden data. In general, digital techniques can be divided into three classes: invisible watermarking, steganography, and embedded data. However, it is desirable for all classes to successfully conceal the hidden information from applicable detectors. Invisible watermarking, generally employed for copyright protection, traitor tracing, and authentication, forgoes a large payload amount for stringent robustness. Steganography, used for covert communication, pursues increased payload size while sacrificing robustness.

Curless, and Szeliski, in this case to reduce error brought about by rounding watemarking the watermark elements. Chapter 7 introduces watermarks created via a genetic algorithm! This can be advantageous in at least two ways: it can increase capacity at same level of perception or decrease potential for successful attack! Chapter 6 describes combinatorial watermarking where a watermark is separated into spatial and frequency components and added to these respective domains of the znd image.
