Visual cryptography is a secret sharingscheme in which secret image is distributed in n number of shares such that, when this n shares are superimposed together, a hidden secret image is get. In extended visual cryptography, we use the cover image for share images, which will give integrating visual cryptography. In this paper, we propose a method for improving the quality of processing halftone images of the share images and the recovered secret image. In an extended visual cryptography scheme the size of the share images and the recovered image is the same as the original halftone secret image. The resulting scheme of extended visual cryptography maintains the quality of original secret image and its security.
