A Cheater Detectable Visual Cryptography Scheme
Kefei Chen · Jisuanji gongcheng · 2005
The visual cryptography scheme(VCS) presented by Naor and Shamir[1] provides a method to encrypt a black-white image to different shares and decrypt the secret without any computations. But if there is a cheater who gives a faked share in the decrypting process, the secret image will fail to be decrypted.this paper gives a construction , which can find out who is the cheater in the decrypting process.
