Book Description
With rapid progress in Internet and digital imaging technology, there are more and more ways to easily create, publish, and distribute images. Considered the first book to focus on the relationship between digital imaging and privacy protection, Visual Cryptography and Secret Image Sharing is a complete introduction to novel security methods and sharing-control mechanisms used to protect against unauthorized data access and secure dissemination of sensitive information. Image data protection and image-based authentication techniques offer efficient solutions for controlling how private data and images are made available only to select people. Essential to the design of systems used to manage images that contain sensitive data—such as medical records, financial transactions, and electronic voting systems—the methods presented in this book are useful to counter traditional encryption techniques, which do not scale well and are less efficient when applied directly to image files. An exploration of the most prominent topics in digital imaging security, this book discusses: Potential for sharing multiple secrets Visual cryptography schemes—based either on the probabilistic reconstruction of the secret image, or on different logical operations for combining shared images Inclusion of pictures in the distributed shares Contrast enhancement techniques Color-image visual cryptography Cheating prevention Alignment problems for image shares Steganography and authentication In the continually evolving world of secure image sharing, a growing number of people are becoming involved as new applications and business models are being developed all the time. This contributed volume gives academicians, researchers, and professionals the insight of well-known experts on key concepts, issues, trends, and technologies in this emerging field.

Book Description
This work is authored by Pratheek Praveen Kumar along with Ruchir Bhgat and Shiksha Suvarna, all three Telecommunications Engineers. Digital Watermarking is the process of irreversibly embedding information into a digital signal. The signal may be audio, pictures or video. There are two types of Watermarking, Visible Watermarking and Invisible Watermarking. In Visible Watermarking, the information is visible in the picture or video. Typically, the information is text or a logo which identifies the owner of the media. Example of Visible Watermark is when a television broadcaster adds its logo to the corner of transmitted video. In Invisible Watermarking, information is added as digital data to audio, picture or video, but it cannot be perceived as such (although it is possible to detect the hidden information). Digital Watermarking schemes are widely being used as potential solution for ownership protection. The Watermarking algorithms in general, may be viewed as digital communication scheme for imperceptible transmission of an auxiliary message through cover image. Several software implementations of the proposed algorithms are available, but very few attempts have been made for the property of robustness and they are not able to provide the good visual Recovery Watermark Image (IWD) as user aspect. This is accomplished by spreading one watermark bit over many samples of the Cover data using a modulated spreading sequence. This is a study of this technology.

Book Description
This book focuses on image based security techniques, namely visual cryptography, watermarking, and steganography. This book is divided into four sections. The first section explores basic to advanced concepts of visual cryptography. The second section of the book covers digital image watermarking including watermarking algorithms, frameworks for modeling watermarking systems, and the evaluation of watermarking techniques. The next section analyzes steganography and steganalysis, including the notion, terminology and building blocks of steganographic communication. The final section of the book describes the concept of hybrid approaches which includes all image-based security techniques. One can also explore various advanced research domains related to the multimedia security field in the final section. The book includes many examples and applications, as well as implementation using MATLAB, wherever required. Features: Provides a comprehensive introduction to visual cryptography, digital watermarking and steganography in one book Includes real-life examples and applications throughout Covers theoretical and practical concepts related to security of other multimedia objects using image based security techniques Presents the implementation of all important concepts in MATLAB
