Abstract
In this paper, a new Visual cryptography scheme for color image is proposed. Our scheme uses color error diffusion for dithering technique which reduces the color sets that renders the halftone image and chooses the color whose brightness variation is minimal. Compared to other V CS schemes that uses different dithering techniques our scheme produces less distortion and the size of the decrypted image is same as the original image. The experimental results also demonstrate the same..
