Abstract

Abstract : Random grids (RGs)‐based visual secret sharing (VSS) has gained much attention in academia than before to avoid the potential drawbacks in visual cryptography‐based VSS. With its still being in infancy, a growing number of researches to RG‐based VSS demonstrate a great potential. Although there are some RG‐based schemes proposed in the past years for different applications, most of them can still be improved to achieve a better performance. This study proposes a new threshold RG‐based VSS scheme with better performance compared with the previous threshold RG‐based VSS scheme. The experimental results illustrate the feasibility; the better performance is theoretically analysed.
