Visual Cryptography Scheme with Autostereogram
Visual cryptography scheme (VCS) is an encryption technique that utilizes the human visual system in recovering of the secret image and does not require any cryptographic computation. Autostereogram is a single two dimensional image which becomes a virtual three dimensional image when viewed with proper eye convergence or divergence. Combing the two technologies via human vision, this paper presents a new scheme called (k, n)-VCS with autostereogram. In the scheme, a secret image is encrypted into n images called shares, each of which can function as an autostereogram. By stacking any k shares, the secret image is recovered visually without any equipment, whereas no secret information is obtained with less than k shares.
