GIS矢量数据水印算法评测研究综述
首发时间:2012-03-29
摘要:以数字水印为代表的版权标记技术日趋成为目前数字版权保护研究与应用的重点。然而,版权标记的深入研究与广泛应用必须以客观、公正的评测方法、评测基准和评测系统的出现为前提。由于GIS矢量数据具有表达方式、存储结构的多样性,以及无固定存储顺序、结构复杂、变换多样、冗余少的特殊性,决定了难以简单地应用现有的版权标记评测技术来进行GIS矢量数据产品的版权标记评测。为此,本文在概述GIS矢量数据水印的基础上,根据国内外学者对数据水印评测所作的相关研究与应用,主要从数字水印评测基准与方法、攻击模型与方法、基准测试数据、基准测试系统等多方面,综述当前国内外对GIS矢量数据产品的版权标记评测技术研究现状与发展趋势。

Review on Watermark Evaluating of GIS Vector Data
Abstract:Digital watermark technology, as a main method of providing copyright protection, has been a hotspot in research and application. However, the further research and widely use on copyright mark must based on objective and impartial evaluation methods, evaluation benchmarks and evaluation system. As the GIS vector data has specialties: such as a variety of expression and storage structure, no fixed storage order, complex of structure, diverse changing, low redundant etc. It is difficult to simply apply existing technologies to copyright mark evaluation of GIS vector data products. This paper, based on summarizing the GIS vector data watermarking characteristics, according to scholars' digital watermarking evaluation research and application, mainly reviewed the status and development trend of copyright mark evaluation research on GIS vector data products in current domestic and foreign.
Keywords: GIS vector data digital watermarking performance evaluation benchmark reviews
