矢量地理数据水印算法的评价研究

Evaluation of Vector Geographic Data Watermarking Algorithm

在数字水印技术中,对水印算法的评价是一个非常重要的步骤。通过分析矢量地理数据质量元素与攻击方法,从矢量地理数据水印算法的鲁棒性和含水印数据的质量两个方面进行水印算法的评价。探讨性的给出了含水印矢量地理数据质量评价模型,并且定量地分析了水印算法的鲁棒性。

In the digital watermarking technology, evaluation of watermarking algorithm is a very important step. In this paper, through the analysis of vector geographic data quality elements and attack methods, evaluation of watermarking algorithm from two aspects the robustness of vector geographic data algorithm and the watermarked data quality. Exploratory determine watermarked vector geographic data quality evaluation model and quantitative analysis of the robustness of the watermark.
