网络地图数字水印版权服务系统实现与应用

大数据环境下地图服务与测绘成果版权保护是一个亟待解决的矛盾问题,数字水印技术是一种有效的版权保护措施,但水印的加入与检索需要专门的技术方法,限制了水印技术的应用。针对该情况该文设计了网络地图数字水印版权服务系统,研究了其基本原理、系统设计、关键技术3个方面,应用C#语言开发,实现了一个基于B/S模式的数字水印服务系统。最后应用实例验证,证明了方法的可行性。

Copyright protection of map services and surveying and mapping results in big data environment is an urgent problem to be solved. Digital watermarking technology is an effective copyright protection measure. However, the addition and retrieval of watermark require special technical methods, which limit the application of watermark technology. In view of this situation, this paper designs the digital watermark copyright service system of network map, and studies its basic principle, system design and key technolog y in the following three aspects. A digital watermarking service system based on B/S mode is developed by using C# language. Finally, an example is used to verify the feasibility of the proposed method.
