Abstract Visual cryptographic scheme is specially designed for secret image sharing in
the form of shadow images. The basic idea of visual cryptography is to construct two or
more secret shares from the original image in the form of chaotic image. In this paper, a
novel secret image communication scheme based on visual cryptography and Tetrolet
tiling patterns is proposed. The proposed image communication scheme will break the
secret image into more shadow images based on the Tetrolet tiling patterns. The secret
image is divided into 4×4 blocks of tetrominoes and employs the concept of visual More >
