Paper Abstract

We describe a method, based on spatial relations, to generate algorithms for watermarking 2D vector map. The method consists of: defining and computing the metric meatures of topological relations between map objects; extracting cover data from metric meatures; deviding the cover data into different subsets; adjusting the spatial relations between map objects within the precision tolerance of the map to make the cover data distribution of one subset shows one of the two expected patterns to suggest the embedding of bit 1 or 0. The method is blind and experiments show that it is also robust.
