New Lossless Random Grids Progressive Secret Sharing Based on XOR for Binary-Image
Li‐Chin Huang, Shu-Fen Chiou, Min‐Shiang Hwang · 2019
Random grids-based visual secret sharing is an important methodology without pixel expansion and codebook. However, random grids-based VSS for general access structure (GAS) had the drawbacks of low visual quality. In this paper, we developed a lossless random grids-based progressive VSS to improve Prasetyo's Scheme utilizing three shared image indices and XOR operation to construct share images.
