Visual cryptography is a secret sharing technique which allows the encryption of an image without requiring any complex computation or knowledge of cryptography.

This unique text/reference describes the fundamental concepts, theories and practice of visual cryptography. The design, construction, analysis, and application of visual cryptography schemes (VCSs) are discussed in detail. Original, cutting-edge research is presented on probabilistic, size invariant, threshold, concolorous, and cheating immune VCS.

Topics and features: provides a thorough introduction to the field of visual cryptography; examines various common problems in visual cryptography, including the alignment, flipping, cheating, distortion, and thin line problems; reviews a range of visual cryptography schemes, including XOR-based visual cryptography and security enriched VCS; describes different methods for presenting color content using visual cryptographic techniques; covers such applications of visual cryptography as watermarking, resolution variant VCS, and multiple resolution VCS.

This logically-structured and comprehensive work will serve as a helpful reference for all researchers and students interested in document authentication and cryptography, including those involved in digital image processing, image watermarking, and media-based security technology.
