空间数据库的共享安全产品LOCKGIS的设计与实现

The Design and Implementation of Spatial Database Sharing Security Product LOCKGIS

目前空间数据库的共享安全仅依赖于关系型数据库的安全性,空间数据在传输共享上的安全无法保障。基于当前空间数据库的使用情况,从其共享存在的安全隐患入手,分析空间数据库共享原理,提出空间数据库共享安全的思路,重点研究空间数据库索引安全性,通过数据库安全访问网关、动态密码生成器、动静态水印追踪等技术来实现空间数据库共享安全。

At present, the shared security ol spatial database is only dependent on the security ol the relational database,and the security of the spatial data in the transmission and sharing cannot be guaranteed. Based on the use of the current spatial database, Starting with the security hidden danger, the paper analyzes the principle of spatial database sharing ,and puts forward the idea of sharing the security of spatial database, Focus on the security of spatial database index ,Through the database security access gateway,dynamic password generator,dynamic and static watermark tracking technology to achieve spatial database sharing security.
