A Novel Non-Expansion Visual Secret Sharing Scheme For Binary Image
In visual cryptography, the secret can be any written text, graphical representation, or picture. This technique, some time called visual secret sharing (VSS), allows visual infor...

Visual Secret Sharing Schemes with Cyclic Access Structure for Many Images
We consider a visual secret sharing scheme with cyclic access structure for n secret images and n shares, where two consecutive shares decode one secret image. This secret sharing ...

Visual Cryptography on Graphs
In this paper, we consider a new visual cryptography scheme that allows for sharing of multiple secret images on graphs: we are given an arbitrary graph (V, E) where every node an...

Real Perfect Contrast Visual Secret Sharing Schemes with Reversing
The visual secret sharing (VSS for short) scheme is a secret image sharing scheme. A secret image is visually revealed from overlapping shadow images without additional computation...
