Abstract

In (k, n) threshold secret image sharing (TSIS), a secret image is shared into n shadow images. Any k or more shadow images can be collaborated together to reconstruct the secret image, while less than k shadow images cannot reveal any secret. All shadow images have the same importance in reconstruction process. In some applications, some participants are accorded special privileges due to their status or importance. In this paper, we consider the (t, s, k, n) essential TSIS (ETSIS) scheme. All n shadows in the proposed (t, s, k, n)-ETSIS scheme are classified into s essential shadows and (n–s) non-essential shadows. In reconstruction, we needs k shadow images with at least t essential shadow images.
