Problems solved by technology

At present, there are two main physical isolation technologies for internal and external networks: one is gatekeeper isolation, which guarantees data transmission between internal and external networks to a certain extent, but it has problems of one-way transmission, efficiency, pure data attacks, and security issues. A series of problems such as vulnerabilities and lack of encryption mechanisms cannot guarantee complete physical isolation
The second is optical gate isolation, which is developed based on network gate isolation technology. Although it effectively avoids the problems of network gatekeepers, it also has its own limitations. For example, the one-way data transmission implementation protocol has limitations. The data transmission model and strategy are insufficient, and the error control technology is insufficient for the verification of one-way transmission data
[0004] For the problems in related technologies, no effective solutions have been proposed yet

Abstract

The invention discloses a natural resource spatial data cross-network query system and method. The system comprises an extranet server, the extranet server is respectively connected with a cloud service extranet database and a switch; wherein the switch is connected with the Internet, the switch is further connected with the intranet switch through a line provided with an isolation switching area,the intranet switch is connected with the intranet server and the intranet spatial database, and the isolation switching area comprises an optical fiber one-way gatekeeper and an image recognition single gate connected with the optical fiber one-way gatekeeper in parallel. Equipment such as isolation exchange equipment is adopted; an automatic transmission technology for recognizing a two-dimensional code picture by utilizing an image is utilized; more information can be transmitted in a very small area; and the reliability of internal and external network exchange of the natural resource space data and the stability of one-way transmission are improved, so that physical isolation is truly realized and met, the problems of illegal leakage, slow transmission and error proneness of the internal network data are prevented, and the security of the internal network data is protected to a great extent.

Description

technical field [0001] The invention relates to the technical field of natural resource spatial data query, in particular to a cross-network query system and method for natural resource spatial data. Background technique [0002] The informatization construction of natural resources continues to deepen, and more and more special business and data query work need to be completed in the Internet environment (hereinafter referred to as "external network"). In order to ensure information security, the government department has established a special office network (hereinafter referred to as "intranet"), and physically separates the internal network from the external network to ensure the security of internal network data. At present, there are two main physical isolation technologies for internal and external networks: one is gatekeeper isolation, which guarantees data transmission between internal and external networks to a certain extent, but it has problems of one-way transmi...
