تکنیک‌های پنهان‌سازی اطلاعات برای استگانوگرافی و واترمارک دیجیتال

A thorough review of steganography, the history of this previously neglected element of cryptography, a description of possible applications, and a survey of methods you can use to hide information in modern media. DLC: Cryptography.

With the scope and frequency of attacks on valuable corporate data growing enormously in recent years, a solid understanding of cryptography is essential for computer/network security practitioners, systems designers, applications developers, and researchers. This timely book delivers the hands-on knowledge professionals need, offering comprehensive coverage on the latest and most-important standardized cryptographic techniques to help them protect their data and computing resources to the fullest. Rather than bogging professionals down with theory like other books on the market, this unique resource describes cryptography from an end-user perspective, presenting in-depth, highly practical comparisons of standards and techniques. Moreover, practitioners learn how to select standardized techniques that are most suitable for their specific needs.

Steganography, a means by which two or more parties may communicate invisibly by hiding secrets in innocuous messages, and watermarking, a means of hiding copyright data in images, are becoming necessary components of commercial multimedia applications that are vulnerable to illegal use. This collection of nine contributions first reviews steganography with a description of possible applications and a survey of methods used to hide information in modern media. The second part introduces watermarking methods, discusses the similarities and differences that characterize watermarking and steganography, and explores the legal implications of watermarking and copyright issues on the Internet.

"Steganography, a means by which two or more parties may communicate using "invisible" or "subliminal" communication, and watermarking, a means of hiding copyright data in images, are becoming necessary components of commercial multimedia applications that are subject to illegal use."--BOOK JACKET. "Inside, you get a thorough review of steganography, the history of this previously neglected element of cryptography, a description of possible applications, and a survey of methods you can use to hide information in modern media. Included is an overview of "steganalysis," methods that can be used to break steganographic communication."--Jacket Steganography, a means by which two or more parties may communicate using ""invisible"" or ""subliminal"" communication, and watermarking, a means of hiding copyright data in images, are becoming necessary components of commercial multimedia applications that are subject to illegal use. This new book is the first comprehensive survey of steganography and watermarking and their application to modern communications and multimedia. Handbook of Information Hiding: Steganography and Watermarking helps you understand steganography, the history of this previously neglected element of cryptography, the As audio, video, and other works become available in digital form, the ease with which perfect copies can be made, may lead to large-scale unauthorized copying which might undermine the music, film, book, and software publishing industries.
