Abstract: -Visual cryptography scheme (VCS) is a cryptography technique which allow visual data i.e.: printed text, handwritten notes, and picture is encrypted in such a way that the decryption can be done by the human visual system, without the support of computers. In order to share undisclosed images, VCS used as a secret sharing schema. The idea is to convert the written stuff into a cipher text by using ElGamal Algorithm and then place that cipher text in to an image and encode this image into n shadow images. The decoding requires only selecting some splits of these n images, creation transparencies of them, and stacking them on top of other transparencies.
