: Nonperfect secret sharing schemes NSSs have an advantage such that the size of shares can be shorter than that of perfect secret sharing schemes. This paper shows some basic prop...
Abstract. This paper first extends the result of Blakley and Kabatianski [3] to general non-perfect SSS using information-theoretic arguments. Furthermore, we refine Okada and Ku...
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...
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...
A secret-sharing scheme realizes a graph if every two vertices connected by an edge can reconstruct the secret while every independent set in the graph does not get any informatio...
