Abstract :
An anti-compression watermarking scheme is proposed. The scheme uses improved Dougleas-Peucker algorithm to compress redundant vertex data, which is important character of vector map, and embeds the watermark into compressed vertex data. Experimental results show that the anti-compression performance of the watermarking algorithm is satisfied.
