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 bookIncludes real-life examples and applications throughoutCovers theoretical and practical concepts related to security of other multimedia objects using image based security techniquesPresents the implementation of all important concepts in MATLAB"--Provided by publisherPPN: PPN: 1026514150Package identifier: Produktsigel: ZDB-4-NLEBK
