Watermarking, which belongs to the data hiding field has seen plenty of research interest recently. There is a lot of work being conducted in several branches in this field.

This blog explains why visible watermarks are more effective as a document copy deterrent.

Handbook of Visual Display Technology pp Cite as. Securely embedding data in digital images has important applications for covert communication and copywrite protection. The specific algorithm used to embed information depends on the characteristics of the application.

Data Hiding and Digital Watermarking

Digital Watermarking. Fundamentals and Techniques. CRC Press, Return to Home Page. 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. The reason is that, although the Internet enables easy, global distribution of documents, this same advantage is a security disadvantage. How do you control distribution to only those who have legitimate access or who have purchased access rights?

How do you prevent legitimate buyers of documents from reselling these illegitimately? How do you prevent a document from being re-authored, effectively misrepresented by a plagiarizer? Internet documents can be anything from text to audio, to image, to video.

We know that there has been much concern from the respective industries most publicly the music industry , and a rush to solutions by the technical community in the form of many watermarking techniques.

This book focuses on image watermarking and describes the basics and more advanced methods of the field. This is a relatively short book, which I consider an advantage. It is pages, including index. However, it is densely packed with all the information that a student, researcher, or practitioner will need to start and to delve well into the fields of image watermarking and steganography.

It is very well-illustrated with example figures and tables that by my count averaged more than 3 per page. Each of the 12 chapters has a list of references of from 10 to 40 in number. The index looks thorough and the table of contents and lists of sections per chapters enables fast lookup of topics of interest. Chapter 1 introduces the field and distinguishes watermarking from steganography. The latter term refers to information-hiding.

Although a watermark is not always hidden in its resident document, it often is. The main feature that distinguishes steganography from watermarking is the following. For steganography, the embedded information is the one and only item of interest, and the document in which that information is embedded simply provides an entity for hiding. However, a watermark contains information specifically associated with the document into which it is embedded e.

Chapter 2 provides watermarking classifications. There is sometimes some confusion in classifying watermarking techniques. This book addresses this by classifying first based on characteristics and second based on applications. Two application classifications are: copyright protection, data authentication, and fingerprinting identification of recipient of document.

Chapter 3 provides mathematical fundamentals, including cosine and wavelet transforms, random sequence generation, and error correction. Chapter 4 provides watermarking fundamentals, including additive and multiplicative watermarking, spatial and frequency domain watermarking, fragile and robust watermarking—the latter by redundancy or spread spectrum approaches.

After these three chapters describing the watermarking basics, Chapter 5 introduces the reader to watermarking attacks, leaving the following four chapters to describe more sophisticated watermarking methods to counteract attacks or for other demands. The attacks discussed in Chapter 5 include: filtering, modulation, compression JPEG , scaling, rotation, cryptographic, and protocol attacks. Chapter 6 describes combinatorial watermarking where a watermark is separated into spatial and frequency components and added to these respective domains of the same image.

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 7 introduces watermarks created via a genetic algorithm, in this case to reduce error brought about by rounding of the watermark elements.

Chapter 8 discusses adjusted-purpose watermarking, in which an appropriate choice is made analytically from the continuum of watermarking methods and from the parameters discussed up to this point in the book. Chapter 9 introduces the challenge of robust high-capacity watermarks that resist attacks. The final two chapters, 10 and 11 are devoted to steganography. Chapter 11 covers steganalysis, that is steganography attacks. These two final chapters are short, but in concert with the preceding chapters devoted to watermarking, they provide a complete picture of the field and a basis for future work—including project work by a student in either watermarking or steganography.

One advantage of this book is that the author and his students have personally contributed to research on many of the techniques. This is evidenced by practical examples included in many of the chapters that, I conjecture, are part of one or more published papers.

The author clearly has extensive and direct research experience with images. These are not covered in the text, so those interested in these applications would need to look elsewhere. However, for anyone—students, researchers, or practitioners—wanting to learn about general watermarking, image watermarking is probably the most straightforward way to start you can see pictures!

Digital Watermarking and Steganography - .Digital Watermarking and Steganography, Second Edition

Lecture notes for undergraduate and first-year graduate students on digital watermarking and data embedding in multimedia data. Steganography is the art and science of hiding data within innocent-looking objects cover objects. Multimedia objects such as images and videos are an attractive type of cover objects due to their high embedding rates.

A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. It is typically used to identify ownership of the copyright of such signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional physical watermarks , digital watermarks are often only perceptible under certain conditions, e.

    Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field.
