Copyright protection of digital content has emerged as one of the most pressing issues in the digital content marketplace. Digital watermarking may provide an effective method for identifying the copyright ownership of digital content such as images, audio and video against unauthorized use and distribution. The basic idea of digital watermarking involves embedding or hiding the copyright and ownership information of digital content imperceptibly as a watermark within the content itself. Our study proposes the development of an efficient digital image watermarking algorithm based on a multiple transform method that combines the benefits of the frequency decomposition ability of the discrete wavelet transform (DWT) and the unpredictable random distribution property of the discrete fractional random transform (DFRNT), while using a 2D barcode to improve the algorithm's robustness, imperceptibility, security and extraction performance. As the first step in developing the proposed system, we implement our watermark generation process by adopting a two-dimensional (2D) barcode as an information hiding method and a self-designed block code pattern in order to ensure the extraction performance of watermarks. A generated 2D barcode is then converted through block code encoding and scrambling conversion, which increase the hidden computational complexity of information, thus bolstering the security of the algorithm. The 2D barcode and block code also feature a self-error-correction function that can correct the bit error in the process of extracting watermark. Next, we implement the multiple transform process by adopting the DWT-DFRNT transform method in order to ensure the robustness and security of the watermarking algorithm. A host image is used as the input signal into 2D-DWT and is decomposed into four frequency sub-bands. The generated sub-band's coefficients are used as input data into DFRNT. Using the quantization technique, we then embed the generated watermark image into the DWT-DFRNT transformed image, transforming the quantized signal through the inverse DFRNT (IDFRNT) and the inverse DWT (IDWT) sequentially. Finally, the watermarked image signal is generated as the output. Experimental results present that our proposed algorithm improves extraction performance by accurately extracting the hidden information in the 2D barcode from the detected watermark. The findings also show that combining the dual transform method, DWT and DFRNT, improves the security and robustness of the watermarking algorithm in defending against basic image signal processing and common attacks.

Digital Watermarking is the art and science of embedding information in existing digital content for Digital Rights Management (DRM) and authentication. Reversible watermarking is a class of (fragile) digital watermarking that not only authenticates multimedia data content, but also helps to maintain perfect integrity of the original multimedia "cover data." In non-reversible watermarking schemes, after embedding and extraction of the watermark, the cover data undergoes some distortions, although perceptually negligible in most cases. In contrast, in reversible watermarking, zero-distortion of the cover data is achieved, that is the cover data is guaranteed to be restored bit-by-bit. Such a feature is desirable when highly sensitive data is watermarked, e.g., in military, medical, and legal imaging applications. This work deals with development, analysis, and evaluation of state-of-the-art reversible watermarking techniques for digital images. In this work we establish the motivation for research on reversible watermarking using a couple of case studies with medical and military images. We present a detailed review of the state-of-the-art research in this field. We investigate the various subclasses of reversible watermarking algorithms, their operating principles, and computational complexities. Along with this, to give the readers an idea about the detailed working of a reversible watermarking scheme, we present a prediction-based reversible watermarking technique, recently published by us. We discuss the major issues and challenges behind implementation of reversible watermarking techniques, and recently proposed solutions for them. Finally, we provide an overview of some open problems and scope of work for future researchers in this area.

This book presents medical image watermarking techniques and algorithms for telemedicine and other emerging applications. This book emphasizes on medical image watermarking to ensure the authenticity of transmitted medical information. It begins with an introduction of digital watermarking, important characteristics, novel applications, different watermarking attacks and standard benchmark tools. This book also covers spatial and transform domain medical image watermarking techniques and their merits and limitations. The authors have developed improved/novel watermarking techniques for telemedicine applications that offer higher robustness, better perceptual quality and increased embedding capacity and secure watermark. The suggested methods may find potential applications in the prevention of patient identity theft and health data management issues which is a growing concern in telemedicine applications. This book provides a sound platform for understanding the medical image watermarking paradigm for researchers in the field and advanced-level students. Industry professionals working in this field, as well as other emerging applications demanding robust and secure watermarking will find this book useful as a reference.

Authenticating data such as image, video, and audio is an important task in digital communication. Another critical task is establishing ownership of the copyright. Digital watermarking is a technique used to provide authentication and ownership of the copyright to the data. Too much digitalization of data in the form of image, video, and audio communicated through various web and mobile applications makes authentication a challenging task. Steganography, the art of hiding tiny pieces of data in image, video, and audio, can also help in copyright protection, authentication, and access control. This book provides three watermarking and two steganography methods and will be a useful resource for graduate students, researchers, and practicing engineers in the field of electrical engineering.

We are happy to present to you the proceedings of the 3rd International Workshop on Digital Watermarking, IWDW 2004. Since its modern reappearance 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 watermarking 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 watermarked. 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 protection has not resulted in widespread use in practical systems. With hindsight, a number of reasons can be given for this lack of practical applications.
