A Quality Maintain Visual Cryptography Scheme
Abstract: Visual cryptography is a cryptographic scheme that focuses on solving the problem of secret sharing of data which hides in images. The multi-secret visual cryptography (MVC) scheme is capable of sharing multiple secret images. Like this, the tagged visual cryptography (TVC) scheme hides tag images in randomly selected shares. But these cryptography schemes creates distortions in the shares at the time of encoding. Due to this, occurs a reduction in the quality of image at the time of decoding. So, this scheme introduces an extended TVC called Lossless tagged visual cryptography (LTVC) scheme where the encoding will not affect the quality of the rebuilt secret image, i. e. , the decoder can rebuild exactly the identical image. Here also introduces a probabilistic LTVC (P-LTVC) to overcome the security issues.
