Problems solved by technology

Blockchain technology can well solve the problem of data collaboration and sharing in public health and safety emergency intelligence, but it needs to occupy a lot of resources and memory for data storage while using blockchain for data sharing. It is easy to have problems such as repeated transactions, resulting in data redundancy and reducing the efficiency of emergency information sharing. In order to solve the above technical problems, the present invention provides a public security emergency intelligence block chain sharing model and method based on side chains

Embodiment 1

[0067] Such as Figure 1-8 As shown, a public security emergency intelligence blockchain sharing model based on side chains is a hierarchical sharing model based on alliance chains, including city side chains, provincial side chains and national main chains, see figure 1 , through the setting of city side chains and provincial side chains, the data transmission volume of the main chain is reduced, and the efficiency of emergency information collaboration and sharing is improved. The side chains of each province and city are set up according to their own emergency intelligence agencies. multiple nodes (D 1 ,D 2 ,D 3 ,…) to complete the upload of emergency information from various agencies to the main alliance chain through data exchange at each level.

[0068] In the city side chain, there are common nodes (N 3 ) and management nodes (N 2 ). Ordinary nodes such as transportation, customs and other departments can provide the latest personnel flow information, and are resp...

Abstract

The invention discloses a public safety emergency intelligence block chain sharing model and method based on a side chain, and relates to the technical field of block chains, the public safety emergency intelligence block chain sharing model comprises a main chain and a side chain, the side chain is responsible for collecting emergency intelligence data and uploading the collected emergency intelligence data to the main chain, and the side chain is provided with an intelligent contract. Cross-chain sharing of data is realized through an intelligent contract, the main chain receives data uploaded by the side chain and realizes data sharing of the data among nodes of the main chain, and the main chain is responsible for verifying, auditing and authorizing identities of partial nodes in the side chain, and realizes daily maintenance of the main chain to guarantee stable operation of the main chain at the same time. According to the method, a hierarchical management form is adopted, a multi-level data storage mode is built inside according to regions and departments, the hierarchical management mode can improve the toughness of the emergency intelligence management system while reducing data redundancy, and cross-chain sharing of data on a side chain is realized through Ethereum and an intelligent contract.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a public security emergency information block chain sharing model and method based on side chains. Background technique [0002] Emergencies have complex characteristics such as diverse causes, rapid spread, differentiated distribution, and unpredictable hazards. In addition, when crises occur, there are often untimely information communication, difficulty in sharing, and difficulty in ensuring authenticity. Coordination and linkage mechanisms between departments at all levels Imperfect, difficult to guarantee material supply, untimely crisis response, unclear responsibility subjects and other multiple difficulties. At present, a mature emergency intelligence coordination mechanism has not been formed. For example, the outbreak of new coronary pneumonia in 2020 has multiple causes, rapid spread, and differentiation. The distribution and hazards are difficult to predict and o...
