Abstract

Abstract:

In this paper,the information hiding technology is used in protecting the 3D 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.

Key words: lossless information hiding；digital elevation mode；integer wavelet with parameters
