摘 要: 为实现对数字影像地图版权保护及合法用户身份鉴定的目的,介绍一种基于波段叠加的影像地图数字水印算法。提出一种波段无损叠加技术,即将合法用户的指纹图像作为数字水印,解析影像地图IMG文件的结构,将指纹特征信息作为水印标识嵌入影像地图的固有文件中。实验和分析表明:该算法具有较好的稳健性,除提供必要版权保护及认证服务外,还能够抵抗多种转换攻击。
关 键 词: 信息安全;信息隐藏;数字水印;影像地图;身份验证

Abstract: To realize the invasion identification and copyright authentication, a novel digital watermarking algorithm for image maps based on band superimposition was introduced. A band lossless superimposed technology was proposed for the compound images, namely the map owner’s fingerprint was taken as watermarks, and the IMG formatted file of image maps was decomposed. The finger features were defined as watermarking, which could be embedded into the files of the map. Experiments and analysis showed that this algorithm had good stability, besides providing services of copyright protection, the model improved the robustness and anti-converting attacks.
