%X By the analysis of the properties of blind watermarking, a method for generating watermark information which transforms characters directly into binary code is proposed. Secondly, the mechanism of coordinate mapping and the principles of constructing mapping function for watermarking embedding and extracting are studied based on the location characteristic of vector geo-spatial data. Then, a blind watermarking algorithm for vector geo-spatial data is obtained using the proposed approaches of generating watermark information and coordinate mapping. The experiments conducted in this paper show that the algorithm is with good robust and can resist some usual attacks such as data compressing, adding, deleting, editing, clipping, translating and so on.
