Visual cryptography is a cryptographic paradigm introduced by Naor and Shamir [Lecture Notes in Comput. Sci., Vol. 950, Springer, Berlin, 1995, p. 1]. Some predefined set of parti...
This paper introduces a color visual cryptography encryption method that produces meaningful color shares via visual information pixel (VIP) synchronization and error diffusion ha...
Visual cryptography schemes have been introduced in 1994 by Naor and Shamir. Their idea was to encode a secret image into n shadow images and to give exactly one such shadow image ...
This paper introduces a novel, cost effective visual cryptography scheme suitable for color image transmission over bandwidth constraint channels. Unlike previously proposed schem...
This paper considers the problem of encoding a secret binary image SI into n shares of meaningful halftone images within the scheme of visual cryptography (VC). Secret pixels enco...
