Digital steganography

Interest in steganography appeared in the last decade and caused widespread multimedia technologies. Steganography methods allow not only to covertly transmit data, but also to solve problems of interference-authentication to protect information from unauthorized copying, tracking the spread of information through communication networks, information retrieval in multimedia databases dannyh.Mezhdunarodnye symposiums hidden data held since 1996, the first symposium on steganography held in July 2002. Steganography - quickly and rapidly developing science, using methods and achievements of cryptography, digital signal processing, communication theory and informatsii.Na Russian language Steganography was dedicated just a few review journal articles. This book is intended to fill this gap. It summarizes the most recent results of investigations of foreign scientists. The book deals with both theoretical and practical aspects of steganography performed stegosystems classification and methods of integration, studied in detail issues of improving capacity stegokanala, ensuring durability and stealth introduction is given more than 50 algorithms embedded dannyh.Kniga intended for students, graduate students, researchers, studying issues of information security, as well as design engineers means of information protection. Also of great interest, it will have experts in the field of information theory and digital signal processing.
