Watermarking 2D Vector Maps on Spatial Topology Domain

Vector maps are valuable asset of data producers. How to protect copyright of vector maps effectively using digital watermarking is a hot research issue. In this paper, geometry invariance property of spatial topological relation is exploited to design a robust, blind algorithm watermarking 2D vector maps. Watermarks are embedded in spatial topological relation by modifying slightly the metric measure of spatial topological relation. Experiments results show that our proposed algorithm has a good robustness against rotation, scaling and translation attack.
