Abstract

This paper presents an algorithm of watermark insertion and extraction on a vector image such as map data. Most parts of the vector image such as map data consists of an array of coordinate values. At first, the image is partitioned into blocks with the same area and every vertex coordinate value within a block is changed to a new coordinate value whose origin is at the south-west vertex of the mask belongs to the associated block. According to the value of the watermark, the insertion area is different. Unlike the work by Sakamoto et al (2000), the authors may be able to use an arbitrary size of the square mask. The mask of the Sakamoto et al.'s work is specific since the length of the mask is 2/sup R/-1 where R=1, 2, ..., n. The authors also show that their method is superior to the previous work against noise attack.
一种基于广义方形掩码的地图数据水印方法
本文提出了一种基于矢量图像(如地图数据)的水印插入和提取算法。矢量图像的大多数部分(如地图数据)由一组坐标值组成。首先,将图像划分为具有相同面积的块,并将块内的每个顶点坐标值更改为原点位于所属块的掩模西南顶点的新坐标值。根据水印值的不同,插入面积也不同。与Sakamoto等人(2000)的工作不同,作者可以使用任意大小的方形掩模。Sakamoto等人的作品的掩码是特定的,因为掩码的长度为2/sup R/-1,其中R= 1,2,…作者还表明,他们的方法在抗噪声攻击方面优于以往的工作。
