摘要： 提出了一种针对矢量图形的数字水印算法，用于矢量图形的版权保护。算法利用了B-spline良好的持续逼近曲线形状的特点，将水印嵌入到B-spline的控制点坐标中。经实验证明，该算法对于通常的图形几何变换，如平移、旋转、缩放以及局部修改攻击，均有令人满意的鲁棒性。
关键词: 数字水印, 矢量图形, B-spline
Abstract: This paper presents a method of digital watermarking of vector graphics to protect its authority.The proposed algorithm adds a spread spectrum sequence to the coordinates of the B-spline control points.Robustness to some common manipulations，such as translation，rotation scaling and local modification，have been proved by the experiment.
Key words: digital watermarking, vector graphics, B-spline
