Description

Electronic government system based on Fabric block chain Technical Field The invention relates to the technical field of electronic government affairs, in particular to an electronic government affair system based on a Fabric block chain. Background E-government affairs refer to a mode of organizing public management by the intensive and strategic application of information communication technical means by a government, and aim to improve efficiency, enhance transparency of the government, improve financial constraints, improve quality of public policies and scientificity of decisions, establish good relations among the government, the government and society, the community and citizens, improve quality of public service and gain wide social participation. The traditional electronic government system is an integrated service system which is necessary to use an electronic informatization hardware system, a digital network technology and related software technology, and has a plurality of defects. The method comprises the following steps: (1) In the actual running of electronic government affairs, the traditional mode has a plurality of dilemmas, but the government affair business cooperation is used as information cooperation in the scene application of government affair business handling, and the core aim is to break the problems through cross-department data sharing and flow integration. Taking enterprise transaction project approval as an example, the enterprise needs to submit a large amount of data, such as project planning, environmental assessment reports, construction drawings, and the like, to a plurality of departments respectively. But the information systems of all departments are mutually independent, the data formats are different from the standards, the data cannot be shared, enterprises can only repeat labor, and a great deal of time and labor cost are consumed. And the approval process among departments is lack of coordination, links are not linked smoothly, information transfer is delayed, the approval period is long, the project propelling and operation efficiency of enterprises are seriously affected, and the regional economic development is hindered. In the social benefit issuing transaction, when departments such as civil administration, social insurance and communities check the qualification of the applicant, key information such as household income, asset condition and the like is difficult to be quickly and accurately checked according to isolation and business process splitting, so that check difficulty and error risk are increased, benefit issuing delay or incorrectness can be caused, and satisfaction degree and trust degree of the public on government service are reduced. (2) In the current government system construction, each department forms a data chimney phenomenon due to the business demand difference. The appearance of the blockchain technology provides a new thought for solving the problems, and the distributed account book and Ha Xicun certificate characteristics of the blockchain technology can construct a full-flow trusted traceability system. However, the fusion of the blockchain and the electronic government system faces a technical adaptation difficult decentralization architecture, meanwhile, the global data consistency is lacking, and under the digital transformation background, electronic government data management faces multiple challenges such as data error accumulation, low integration efficiency of heterogeneous systems, non-uniform data confidentiality level, inter-department information barriers and the like, so that the value mining and application efficiency of government data are severely restricted. (3) The electronic government affair data can generate a large amount of implicit information, and the government affair data has great difference from common data, each piece of data contains vital information, and people cannot directly observe the data, so how to efficiently and safely acquire, analyze and intuitively display the massive data generated in the electronic government affair scene becomes a key problem. Disclosure of Invention Aiming at the defects of the prior art, the invention aims to provide an electronic government system based on a Fabric block chain, which can overcome various defects of the electronic government system in the prior art through the arrangement of three components, namely a department business cooperation component, a block chain data management component, a data visualization component and the like. In order to achieve the above purpose, the invention adopts the following technical scheme: An electronic government affair system based on Fabric block chain is characterized by comprising: the cross-department business collaboration component is used for realizing a trust and consensus mechanism among departments, and comprises the steps of generating an identity file by using a CA tool to provide authentication service, ca
