Research And Development Of Community Management Information System Based On Block Chain

With the development of social public service,the importance of community management is increasingly prominent,the scope of management and the amount of information are explosive growth,and the development of safe,reliable,efficient information management system is imminent.Community management information system on the market today,generally are based on the traditional B/S structure and Web technology of information system,this mode of the system,the information set in a central server,system permissions in the hands of some people,once the system under attack,can easily lead to information security of the information or data been tampered with.Aiming at the above problems,this paper combined with the decentralization of blockchain and the characteristics of data cannot be tampered with,and developed a new community management information system.The main research and design contents are as follows:(1)Model construction of community management information system based on blockchain.In view of the problems of the traditional community management information system,this paper analyzes the needs of the system,and constructs three system models according to the different roles of the system,including the community committee management model,residential property management model and community residents’ management model,as the basis of system design and development.(2)Design of community management information system based on block chain.According to the model constructed,this paper designs three subsystems and fifteen functional modules,and mainly designs the security of the community management subsystem and the blockchain data protection subsystem.In the community management subsystem,the three models are designed in detail.In the blockchain system,the smart contract is designed,deployed and invoked,and then security analysis is done to verify the availability of the system.(3)Implementation and test of community management information system based on block chain.Platform for development of this system in the etheric fang,using Active Server Pages was carried out on the front end the application layer design,using intelligent contract will front end and the underlying block chain to connect,then complete the data distributed management,make the system function,the final test to the functions of the various subsystems.Through the operation of the system,the system stores the community information on the blockchain,which ensures the security of the data in the system and meets the security requirements of the current community information management.
