摘　　要：提出了一种基于矢量要素对象存储顺序的数字水印方法。利用算术编码技术,将水印信息隐藏在矢量对象的存储顺序中,实现了对数字水印的嵌入与提取。实验表明,该算法不会改变数据的几何精度,具有较好的透明性,对裁剪、缩放、平移、旋转、坐标转换等攻击具有较好的鲁棒性。This paper presented a watermark method based on the storage sequence of vector elements. This method used the arithmetic coding technique to hide the watermark information in the storage sequence of vector objects, and realized to embed and extract the digital watermark. The experimental results show that the algorithm does not change the geometric accuracy of the data, and has better transparency and robustness to map cutting, zooming, panning, rotating, coordinate conversion and other attacks.
