Probabilistic visual cryptography schemes [PDF]

open access: yes, 2011
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]

open access: yesTransactions on Combinatorics, 2019
‎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

open access: yes, 2012
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 ...

Lossless sharing visual cryptography

open access: yesTongxin xuebao, 2013
According to the information loss during the secret image sharing process, the lossless sharing visual crypto-graphy was proposed. The optimizations of two parameters were simplified into one parameter.

A cheating prevention EVC scheme using watermarking techniques

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2012
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.
