摘要
本文研究利用基于Arnold变换的图像置乱技术,对数字地图进行置乱,再将置乱的图像进行分割,以实现数字栅格地图的数据分存。最后通过算例对地图数据分存的效果进行了验证,结果表明所提出的算法可以有效地对地图数据进行分存并有效加密,提高数据的安全性与系统的鲁棒性。
In the paper, digital raster maps were scrambled with scrambling technique based on Ar- nold transformation, and the scrambled images were split to implement data sharing of the map. Finally, the performance of data sharing was tested, and result showed that the algorithm could implement the da- ta sharing and encryption of digital raster maps, which improves the information security and the robust- ness of the system.
