刘绪崇1,2,王建新1,胡华平3,罗永4 . 纹理图像无损隐藏三维DEM数据技术[J]. 计算机工程与科学, 2010 , 32(10) : 63 -65 . DOI: 10.3969/j.issn.1007130X.2010.
In this paper,the information hiding technology is used in protecting the 3D landform data. The information of elevation is hidden in the texture. Keeping the terrain figure and hypsography,the terrain information is compressed in low bit ratio. The landform data are embedded into the texture data by an improved histogram shift. The texture data can recover losslessly after the data are restored. The hidden DEM data can not be detected easily,and the data can not be drawn restored by the illegal user without the key.
