Abstract :
A disguise algorithm about DEM data is proposed in this paper, and it is based on matrix transformation and cryptographic algorithm. In this algorithm, a terrain is generated with a parametric surface, which is generated by the two element trigonometric function. The security communication of DEM data is realized through the discretization of the real DEM data and the terrain. Experiments prove that this algorithm is safe and efficient. This scheme can be used widely in DEM data protection field.
