Secret Sharing of Digital Raster Maps Based on Image Scrambling

Secret sharing of digital raster maps is studied. Digital raster maps are scrambled with scrambling technique with Arnold transformation, and the scrambled images are split to implement secret sharing of the map. The performance of secret sharing is tested with software developed independently. It is demonstrated that the algorithm can implement secret sharing of digital raster maps, improving the information security and the robustness of the system, and encryption of the data is implemented at the same time.
