空间地理信息数据安全方案研究与应用实践——以南京为例

The Application of Digital Watermarking and Encryption in the Data Security of Geographic Information——A Case in Nanjing

测绘地理信息数据共享工作的进一步深入以及国家新型基础测绘的转型发展,对测绘地理信息应用需求越来越旺盛,数据安全工作刻不容缓。本文对空间地理信息数据安全方案进行了研究,并将数字水印、数据加密和电子签章技术在南京测绘地理信息安全方面进行了应用实践。本文主要研究内容为:分布式网络环境下的系统架构、功能模块的组织构成、与其他业务系统的集成方案等,为数据版权保护、责任认定和事先控制提供了有效技术方法。

The further development of surveying and mapping and geographic information data sharing,and the transformational development of national new basic surveying and mapping,bring more and more demand for surveying and mapping and geographic information application.Data security work cannot be delayed.Spatial geographic information data security scheme was researched in this paper,digital watermarking,data encryption and electronic signature technology have been applied in the field of surveying and mapping and geographic information security in Nanjing.The research content mainly includes system architecture in a distributed network environment,the organizational structure of the functional modules,integration with other business systems,etc,Which provide an effective technical approach to data copyright protection,liability identification and prior control.
