Air monitoring data storage system and storage method based on block chain

Abstract

The invention is applicable to the technical field of information security, and provides an air monitoring data storage system and a storage method based on a block chain. The system comprises a management server, a plurality of air monitoring data recording nodes and a plurality of air monitors used for air monitoring. The management server and the air monitoring data record node adopt the unionchain way to establish the chain, the block chain network; the management server is used for establishing the creation block; the air monitor packages the air monitoring information, the digital signature of the air monitor and the public key of the air monitor to generate air monitoring data packets, and then distributes the air monitoring data packets to the block chain network through the wireless data transmission module. The first air monitoring data recording node receives the air monitoring data packet, stores the air monitoring data in the block body of the new block, obtains the current time, adds the current time to the block head of the new block, and publishes the new block to the block chain network. The first air monitoring data recording node receives the air monitoring datapacket, stores the air monitoring data in the block body of the new block, obtains the current time, adds the current time to the block head of the new block, and issues the new block to the block chain network. The invention enhances the safety of the air monitoring data storage system.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a blockchain-based air monitoring data storage system and storage method. Background technique [0002] Air monitoring refers to the fixed-point, continuous or regular sampling and measurement of pollutants present in the air. The purpose of air testing is to reflect the status quo and development trend of air quality in a timely, accurate and comprehensive manner, and to provide scientific basis for air management, pollution source control, air planning, and air evaluation. [0003] However, in the existing air monitoring data storage system, the air monitoring data package is easy to be tampered with, which is not conducive to enhancing the security of the air monitoring data storage system. The reason is that the existing air monitoring data storage system adopts a centralized storage method, and this centralized storage method is easy to be breached,...
