%X In this paper a new visual cryptography scheme is proposed for hiding information in images which divide secret images into multiple shares.In order to provide more security to existing schemes a new Technique called Digital Watermarking is used,and to improve the quality and size of images obtained color error diffusion technique is used .secret information can be retrieved by stacking any k number of decrypted shares. which reduces the color sets that renders the halftone image and chooses the color whose brightness variation is minimal
