Visual cryptography vs bit level secret sharing for image encryption

Abstract

In this paper I proposed a new secret sharing algorithm for image encryption. The simplest form of our proposed system separates a secret image into two layers so that each layer by itself conveys no information, but when the layers are combined the secret image is revealed. This algorithm is suitable for all kind of images (binary, gray, color), and can be effectively implemented by software.Keywords: Visual cryptography; Secret sharing; shares; Image encryption; Bit-level
