Visual Cryptography and Secret Image Sharing

This book covers an extensive range of topics related to visual cryptography techniques and secure image sharing solutions. It addresses sharing multiple secrets and visual cryptography schemes based on the probabilistic reconstruction of the secret image, including pictures in the distributed shares, contrast enhancement techniques, visual cryptography schemes based on different logical operations for combining shared images, cheating prevention, and the alignment problem for image shares. The book also describes practical applications, steganography, and authentication. Case studies demonstrate the effectiveness of the techniques.
