The transition of visual secret sharing from a black & white secret image to a color image is not straight-forward. There are several models of color superposition principle. In this paper we present color visual cryptographic scheme realizing monotone access structure. We first give a generic construction method to share a color image in same color model. In particular, our construction achieves maximal contrast. We also give a direct and efficient construction of visual secret sharing for (k, n) ∗-access structure. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.
