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.
Digital Watermarking and Steganography
Digital audio, video, images, and documents are flying through cyberspace to their respective owners. Unfortunately, along the way, individuals may choose to intervene and take this content for themselves. Digital watermarking and steganography technology greatly reduces the instances of this by limiting or eliminating the ability of third parties to decipher the content that he has taken. The many techiniques of digital watermarking (embedding a code) and steganography (hiding information) continue to evolve as applications that necessitate them do the same. The authors of this second edition provide an update on the framework for applying these techniques that they provided researchers and professionals in the first well-received edition. Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field research and deal with the other. New material includes watermarking with side information, QIM, and dirty-paper codes. The revision and inclusion of new material by these influential authors has created a must-own book for anyone in this profession. - This new edition now contains essential information on steganalysis and steganography - New concepts and new applications including QIM introduced - Digital watermark embedding is given a complete update with new processes and applications
Digital Watermarking and Steganography
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. The genetic algorithm (GA) based watermarking technique solves the rounding error problem and provide an efficient embedding approach. Each chapter provides the reader with a fundamental, theoretical framework, while developing the extensive advanced techniques and considering the essential principles of the digital watermarking and steganographic systems. Several robust algorithms that are presented throughout illustrate the framework and provide assistance and tools in understanding and implementing the fundamental principles.
