【摘要】 本文以课题“基础地理信息数据产品数字水印技术研究”为基础 ,研究出一套在GIS空间数据中隐藏标识数据生产单位版权以及用户使用权属的数字水印并对其进行压缩、加密的GIS空间数据安全管理技术方法 ,并从实际出发 ,设计了相应的应用程序技术方案 ,并给出了部分软件实例验证。这一技术方法的研究对于GIS空间数据的安全管理和安全共享都有很大意义 ,也是对数字水印应用新领域的探索更多还原

【Abstract】 This paper provide a technology method of security management of GIS spatial data by compressing, encrypting the digital watermark which hides the sign of the copyright and using right . Accordingly, a set of technology scheme of applying program is designed and some software example are given to verify. The technology method is meaningful to the security management and security sharing of GIS spatial data and is a new investigation in the application field of digital watermark.更多还原
