摘要

针对栅格地图中涉密数据可分为不同图层的特点，设计了一种保护多层数据的区域递增式彩色视觉密码方案，并给出了具体应用流程。该方案首先对多个授权集合进行了优化，然后基于随机数设计了秘密分享和恢复算法，避免了生成和保存加密矩阵产生的额外开销。实验结果表明，该方案能够实现栅格地图数据多级分存，在大大降低方案像素扩展度的同时，实现了栅格地图数据的完全恢复。

Abstract

In view of the characteristics of raster map

important data of the map were divided into different map layers by using the idea of map segmentation.A regional incremental color visual cryptographic scheme for raster map sharing was designed

and a model based on this scheme was proposed.At the same time

the specific application process was given.In order to solve the problem of large pixel expansibility and poor visual effect of image recovery in traditional regional incremental visual cryptography scheme

random numbers and the access structure optimization were used.Construction of the method was simple and the additional overhead of generating and saving the encryption matrix was avoided.The experimental results show that the scheme can achieve multilevel raster map sharing with the map’s perfect recovery

meanwhile the extension of the scheme pixel is greatly reduced.
