摘　　要：地理信息作为国家基础建设的关键数据,对其进行版权保护的重要性不言而喻。然而,现有地理信息数字水印系统均基于Windows系统进行开发,无法实现软件的自主可控及满足在Linux操作系统上实现地理信息版权保护的需求。因此,基于开源的地理空间数据抽象库(GDAL),采用Java语言、Swing框架开发了适用于Linux系统的地理信息数字水印系统,并从系统设计、关键技术、系统实现等方面介绍系统及其实现细节。该系统由水印嵌入、水印检测、日志管理、权限管理4个部分组成,针对不同的地理信息数据格式分别设计了数字水印算法,在实现过程中解决了读写ESRI FileGeodataBase(FileGDB)数据的问题。实验表明,该系统的不可感知性强、算法鲁棒性较高,可抵抗常见的攻击,弥补了当前地理信息版权保护软件在Linux系统中的空白,真正实现了GIS软件的自主可控,为推动GIS软件国产化作出了积极贡献。ion Library(GDAL),this paper develops a geographic information digital watermarking system for Linux operating system by using Java language and Swing framework,and introduces the system and its implementation details from the aspects of system design,key technologies,system implementation,etc..The system consists of four parts:watermark embedding,watermark detection,log management,and permission management,and it designs digital watermarking algorithms for different geographic information data formats and solves the problem of reading and writing data in ESRI FileGeodataBase(FileGDB)in the process of implementation.The experimental results show that the system is imperceptible and the algorithm is robust against common attacks.The implementation of this system makes up for the blank of the current geographic information copyright protection software in Linux system,truly realizes the autonomy and control of GIS software,and makes a positive contribution to promoting the localization of GIS software.
