Abstract

In this paper, we propose a new digital watermarking method for protection of vector maps in geographic information systems. The method is based on a combination of two novel approaches. Firstly, the watermark is embedded into polygon objects of the map by cyclically shifting the vertex list of each polygon. Secondly, a raster image, superimposed on the map, is considered as a watermark. The major advantage of this method is that, unlike most existing watermarking techniques, it does not distort the map by altering the coordinate values. Experimental results demonstrate the efficiency of the proposed method, as well as the robustness of the embedded watermark against common geometric transformations: translation, scaling, rotation and cropping.
