基于集对理论的矢量地图水印算法评价模型

随着地理信息系统的发展,矢量地图在生活的各个领域已经得到广泛的应用。作为一种数字化数据,矢量地图具有易被非法复制、篡改、传播等特点,从而导致数字矢量地图的版权保护问题日益严峻。目前学者们提出了众多针对矢量地图版权保护的数字水印算法,但由于鲁棒性标准各不相同,因此很难得到一个比较公正的评价。通过分析现有的矢量地图水印算法,总结矢量地图水印攻击类型,结合集对理论,提出一种比较通用的适用于矢量地图水印算法的评价模型。

Evaluation Model of Vector Map Watermarking Algorithms Based on Set Pair Analysis

With the development of geographic information system(GIS),vector map has been widely used in all areas of life.As a kind of digital data,vector map risks of illegal copying,tampering,communication,etc.It makes the copyright protection of vector maps an increasingly serious problem.Currently,a number of scholars have proposed kinds of watermarking algorithms.However,without uniform standard,it is very difficult to give a more fair assessment of the watermarking algorithms.This paper proposed a more general evaluation of vector map watermarking model by analyzing the existing vector map watermarking algorithm,summarizing vector map watermarking attack classification and combining theory of the set pair analysis.
