Visual cryptography is a method offering plan which uses pictures circulated as shares such that, when the shares are stack, a sensitive or secrete image is uncovered. According to extended visual cryptography, the offer pictures are built to hold compelling spread pictures, accordingly giving open doors to coordinating visual cryptography and biometric security methods. In this paper, the authors propose a scheme for halftone pictures that enhances the nature of the shares generated from secrete image and the recouped secrete picture in an extended visual cryptography plan for which the figure size of the secret pictures and the reconstructed picture by stacking shares is the similar with respect to the first halftone secrete picture.
