摘　　要：针对矢量地图数字水印抵抗解释攻击的鲁棒性能较差的特点,提出了一种静态双重水印算法.利用版权信息构造版权子水印,同时,对矢量地图进行域划分构造特征子水印,并将身份子水印嵌入特征子水印中形成静态双重水印.实验表明,该算法能够大幅度提高水印抗几何变换及数据压缩攻击的能力,子水印的互认证机制使得算法对于解释攻击具有突出的鲁棒性能.Digital watermarks for vector maps are less robust against anti-interpretation attacks.A static dual watermarking algorithm was proposed that begins with a child copyright watermark that is formed using copyright information.This can be embedded into another child watermark consisting of features selected by fuzzy c-means clustering from the vector map.Both are then formed into a compound watermark.Experimental results showed that the algorithm can enhance resistance to geometric transformations and compression.In particular,the mutual authentication of dual watermarking improved robustness against anti-interpretation attacks.
