Threshold Visual Cryptography Schemes With Tagged Shares
IEEE Access, 2020 The appearance of shares encoded by traditional visual cryptography is not easy to distinguish and meaningless. It means the shares cannot be managed efficiently nor user-friendly. A tagged visual cryptography scheme (TVCS) provides additional tag images

Visual cryptography scheme on graphs with $m^{*}(G)=4$ [PDF]
Transactions 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 ...
