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
