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.
