A system and method for sharing spatial data based on distributed ledger

Abstract

The invention belongs to the technical field of spatial information storage, and discloses a distributed ledger-based spatial data sharing system and method. The distributed ledger-based spatial data sharing system includes: system function modules of a system application layer and a business layer, and data storage access Layer data storage module; the system function module includes: account information management module, block chain network management module, transaction record management module and data quality management module. The present invention adopts the method of combining blockchain technology and spatial data sharing to realize a distributed storage system integrating spatial data distribution, sharing and recording; and ensures the authenticity of spatial data sharing records by using the non-tampering property of blockchain ledger data. security and security; using distributed technology features to increase the transparency of data flow, realize the authenticity and security of data distribution, sharing and recording, and solve the problems of single point of failure, data tampering and data traceability in the past.

Description

technical field [0001] The invention belongs to the technical field of spatial information storage, and in particular relates to a system and method for sharing spatial data based on a distributed ledger. Background technique [0002] At present, the rise of the Internet industry has brought mankind into an unprecedented information age. The most valuable thing in the 21st century is not only technology, but also data. Humans explore massive geospatial data related to eco-geography, earth science and human life through ever-changing technologies, and conduct multi-field and comprehensive analysis and processing of the acquired spatial data, so as to solve the current resource utilization, environmental security and natural disasters, etc. Therefore, creating value by analyzing and processing spatial data has become a hot research topic. Spatial data often has a huge amount of data and complex data formats, which also causes spatial data ports in different regions and indu...
