• In this paper, we treat visual secret sharing scheme(VSSS)for color images. We first evaluate the brightness of the decrypted color image under certain conditions on the mixture of colors. We obtain a general formula for the construction of VSSS using mixture of colors. We second propose an iterative algorithm for constructing VSSS in a practical situation. If we use the iterative construction, we have only to solve partial differential equations with small n even if n is actually large, where n denotes the number of participants. This iterative construction has never discussed in the both cases under the original images are black-white images and color images. Finally, we propose the way to embed a color image on each share for the case that the original image is color.
