Visual cryptography is one of those unusual cases that kind of looks like a good idea, but it turns out is fraught with problems. The idea is straightforward enough — an image to encrypt is sampled ...

Visual cryptography scheme is a cryptographic technique which allows visual information to be encrypted into several shares in such a way that the decryption can be performed by the human visual ...

Visual cryptography scheme is an encryption method that is used to encode secret written materials into an image and encode this image into n share images. The decoding only requires only selecting ...
