本文提出了一种基于Voronoi图的禁止结构的图像共享方案。图中每个Voronoi多边形代表一个图像共享的参与者,图中具有非邻近关系的参与者是授权子集,即图中满足非邻近原则的成员可以恢复图像秘密,而其他成员的组合则不能得到图像秘密的任何信息。结果表明该算法是有效的。
This paper presents a forbidden structure image sharing scheme based on Voronoi diagram. In the figure, each Voronoi polygon represents an image sharing participant. Participants with non-contiguous relations in the graph are authorized subsets. In this figure, members satisfying the non-contiguous principle can recover image secrets, while other members’ combinations can not obtain Image secret any information. The results show that the algorithm is effective.
