On the technical logic of geographic information confidentiality

Abstract

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
