摘要/Abstract

摘要：

如何有效化解地理信息保密与应用的矛盾是世界各国共同面临的难题。长期以来，我国地理信息保密技术缺乏坚实的理论基础，其技术逻辑无法有效支撑管理逻辑，加剧了地理信息保密与应用的矛盾。针对这一问题，本文基于信息不确定性理论，利用信息的特有属性，结合国家秘密的基本要素，提出地理信息保密的技术逻辑。认为地理信息是其确定性和不确定性内外交织的综合体；其内在不确定性此消彼长，引起地理信息重要性与可靠性的上下波动，触发地理信息密与非密的相互转换，是地理信息保密的内在逻辑；进一步厘清了地理信息定密、脱密与评估的技术逻辑。最后指出地理信息保密技术逻辑支撑管理逻辑的路径。

Abstract:

How to effectively resolve the contradiction between the security protection and application of geographic information is a common challenge faced by countries worldwide. For a long time, due to the lack of a solid theoretical foundation for geographic information security technology in China, its technical logic has failed to effectively support the management logic, exacerbating the contradiction between security control and application of geographic information. To address this issue, based on the theory of information uncertainty, this paper proposes the technical logic of geographic information security by utilizing the unique attributes of information and combining the basic elements of state secrets. It holds that geographic information is a complex integrated entity intertwined with certainty and uncertainty internally and externally. The dynamic fluctuation of its inherent uncertainty causes changes in the importance and reliability of geographic information, triggering the mutual conversion between classified and unclassified geographic information, which constitutes the inherent logic of geographic information security. Furthermore, this paper clarifies the technical logic of classification, declassification and assessment of geographic information. Finally, it points out the path for the technical logic of geographic information security to support the management logic.

Key words: geographic information confidentiality, geographic information security, uncertainty, information entropy, technical logic
