网络环境下的地理信息数据保密与安全

Confidentiality and Security of Geographical Information Data in Network Environment

随着计算机业的迅猛发展,越来越多的测绘人将计算机视为测绘工作不可缺少的重要工具。但计算机如果离开了计算机网络,计算机将变为"孤岛",无法实现数据的传输、共享等重要的功能,严重制约地理信息数据的处理。随着计算机网络的共享性、开放性、互通性的增强,网络安全问题变得尤为关键,特别是测绘本身就是涉及处理保密数据的工作,地理信息数据的安全在测绘单位的计算机网络保密管理中更是至关重要。

With the rapid development of the computer industry,the computer has been regarded as an indispensable tool by a growing number of people who are engaged in the area of surveying and mapping.However,without the network,the computer will not be able to implement the important functions such as data transfer and sharing,making the computer to become an ' island' and seriously restricting its processing of geographical information data.With the enhancement of sharing,openness,and interoperability of the computer network,the issues of network security have become very critical,especially for surveying and mapping which involves the work of processing confidential data.Therefore,the data security is very essential in the security management of computer network in surveying and mapping companies.
