一种适用于移动端瓦片地图的加密方法

A Novel Map Encryption Solution for Mobile Map Application on Tiles

在移动端地图大行其道的今天,如何保证地图服务不被盗用和防止信息泄漏是一个亟待解决的难题。针对这种情况,本文提出了一种适用于移动端瓦片地图的加密方法,通过对地图瓦片入库顺序的置乱,以及对瓦片的图层行列值信息的加密,使得移动端地图瓦片在被非法使用时地图信息无法还原,提高了移动端上地理信息应用的安全性。

Nowadays,mobile map applications have been applied everywhere.Protecting the copy rights and some private information of the maps is a hot topic.An encryption method for map tiles in mobile application is given in this paper,the sequence of the tiles would be scrambled by the random numbers,which are created by the tile＇s row,column and level values.This approach is able to keep the map unreadable in the illegal application,which can enhance the protection.
