Land data storage method and system based on block chain and storage medium

Abstract

The invention provides a land data storage method and system based on a block chain and a storage medium, and the method comprises the steps: obtaining land pattern spot information, and determining to-be-stored land data based on the obtained land pattern spot information; performing hash processing on the to-be-stored land data to extract a digital fingerprint of the to-be-stored land data; packaging and uploading the to-be-stored land data and the corresponding digital fingerprint, and obtaining a corresponding transaction identifier and a block number; and storing the transaction identifiers and the block numbers in an under-chain database in a one-to-one correspondence manner. According to the method, the security of the land data is improved, and the query speed of the land data is also improved.

Description

technical field [0001] The invention relates to the technical field of land data storage, in particular to a method, system and storage medium for land data storage based on blockchain. Background technique [0002] Land map survey is an important means to comprehensively verify and find out land resources, and it is one of the basic contents of land resource management. The construction of land information database has the risk of large data volume, difficult management, and easy tampering. The collection of geographic patches is divided into three parts: firstly, obtaining remote sensing image data and producing orthophoto maps, then extracting survey information and making survey basemaps, and finally carrying out the work of property boundary line maps and supplementary surveys. Among them, the investigation work includes special land use investigation and evaluation, land use status investigation and land ownership investigation. After the geographic data collection is...

Problems solved by technology

Due to the complex sources of geographical data and the wide distribution and large volume of data, data inconsistencies or even minor data tampering are prone to occur in the process of database construction. This situation is extremely difficult to detect, and traditional methods are difficult to effectively supervise data. Reduce the credibility of the data in the database

In addition, in the later land verification process, it is difficult to trace the original land use situation, and there will be situations where it is impossible to check whether the land is illegally occupied, and the workload will be increased due to incomplete traceability information.
