Probabilistic visual cryptography schemes [PDF]
Visual cryptography schemes allow the encoding of a secret image, consisting of black or white pixels, into n shares that are distributed to the set P of n participants.

Visual cryptography scheme on graphs with $m^{*}(G)=4$ [PDF]
Let $G=(V,E)$ be a connected graph and $\Gamma (G)$ be the strong access structure where obtained from graph $G$. A visual cryptography scheme (VCS) for a set $P$ of participants is a method to encode a secret image such that any pixel of this image ...

Progressive Visual Cryptography With Unexpanded Shares
The basic (k, n)-threshold visual cryptography scheme is to share a secret image with n participants. The secret image can be recovered while stacking k or more shares obtained; but we will get nothing if there are less than k pieces of shares being ...

A cheating prevention EVC scheme using watermarking techniques
Visual Cryptography (VC), proposed by Naor and Shamir in 1994, is a variation of the conventional secret sharing scheme. In VC, instead of a numerical secret key, a secret image is shared among participants in the form of images called shares.
