摘要

为实现对数字地图侵权追踪及合法用户身份鉴定的目的

提出一种基于身份验证的矢量地图数字水印模型。提出一种双图分形编码技术

即将合法用户的指纹图像作为分形的定义域

矢量地图作为值域

以分形相近性计算的控制参数及指纹自身特征信息作为水印标识嵌入矢量地图的属性文件中。实验和分析表明

模型具有较好的稳健性

除了提供必要版权保护及认证服务外

提高了对地图拥有者的身份验证概率。

Abstract

To realize the invasion identification and copyright authentication

a novel digital watermarking model for vector maps based on authentication was introduced.A double images fractal coding technology was proposed for the compound images

namely

the map owner’s fingerprint was taken as the domain blocks and the vector map was taken as range blocks.The control parameters of fractal similarity computation were defined as watermarking

which could be embedded into the properties file of the map.Experiments and analysis show that

besides providing services of copyright protection

the model improves the robustness and the owners’ authentication probability.
