Reversible Secret Image Sharing without Polynomial
Gil‐Je Lee, Dae-Soo Kim, Kee-Young Yoo · Advanced science and technology letters · 2014
In this paper, we propose a (n, n)-threshold reversible secret image sharing scheme using histogram shifting. Unlike Shamir’s secret sharing, the proposed scheme does not utilize polynomial operation and Lagrange’s interpolation. We evaluate image distortion ratio between original and shadow images. As a result, the image distortion ratio of the proposed scheme are superior to previous schemes.
