BoBoCoAe, 201 — 163 p. — ISBN: 8740301265, 9788740301267In this book, one of data security methods known as visual cryptography (VC) is presented.Specifically, visual cryptography allows effective and efficient secret sharing between a number of trusted parties. As with many cryptographic schemes, trust is the most difficult part. Visual cryptography provides a very powerful technique by which one secret can be distributed into two or more shares.
Practical VC applications are also outlined. These applications involve the use of Moire patterns and watermarking techniques. Detailed analysis of the watermarking domain is presented along with various techniques and schemes that can incorporate VC successfully within the field of watermarking.
The foundations of these techniques are reviewed and examples provided.Contents:
