| Abstract: | In order to improve the efficiency in manual distribution of map data and the security of the network distributing,the paper introduces information hiding technologies into the process of map data distributing on the network. The common workflow of map data distributing on the network using data hiding technologies is described firstly. Then, the key technologies are analyzed in detail, such as map data organization before distributing and reorganization after reception,map data hiding and analyzing. Those works lay a foundation for the researches on hiding technologies of map data distributing on the network. |
