TL;DR: In this paper, a new type of cryptographic scheme, which can decode concealed images without any cryptographic computations, is proposed, which is called k-out-of-n secret sharing.
Abstract: In this paper we consider a new type of cryptographic scheme, which can decode concealed images without any cryptographic computations. The scheme is perfectly secure and very easy to implement. We extend it into a visual variant of the k out of n secret sharing problem, in which a dealer provides a transparency to each one of the n users; any k of them can see the image by stacking their transparencies, but any k-1 of them gain no information about it.
