Environment is made of the telecommunications room of mandate IP address, and node server is located in the server of different business department and operation is
System, each node server have a full dose data of government affairs information block chain, data according to the design of system of catalogs database,
The all information of citizen, legal person by identity card grouped record.All government affairs shared data submissions are all deposited as transaction record
In block chain network, the network node of all participants preserves complete data, can not distort for storage.Each business department pair
The private key of node server storing user's registered answered, this private key represent the unique identities of participant, only possess the people of private key
Member can initiate the operation to own account, and other operations are invalid.Wherein, private key can export, dump, duplication.
Business department is connected directly to the node server of each department, carries out account operation, the service of new business department
All public account books of history of automatic synchronization after device addition network.Wherein, the relevant technologies that each node server uses include：Base
The operating system and database software of plinth；Block chain technology, including：Point to point network transmission technology between node server,
Distributed account book technology, asymmetric cryptosystem and verification technique.Whole nation index chain is formed by the index node in each city, indexes chain
Information extract important information in the full dose information of city by index node and collect, each index node passes through whole nation index
Chain shared data, the common national index information of storage can feed back the citizen, legal person all by the retrieval to index node
The data cases in city want that obtaining full dose information needs to transfer the full dose information to Yingcheng City by the interface between City Chain.
System of catalogs is the information service system built to find and positioning all kinds of government information resources of dispersion.According to
Business demand according to unified information resource catalogue system standard, catalogues to related government affairs information on services resource, generates political affairs
Business service public information resource catalogue and Exchange Service catalogue.System of catalogs database further includes citizen's message catalog system：It will
Citizen is collected in the information of different government affairs departments by system of catalogs, and the personal data of different stage are formed after collecting, can be with
It is needed to set different access rights according to different stage, appropriate data can be decrypted according to authorizing in ciphertext data；With
And corporate message's system of catalogs：Corporate message is against information such as information, the tax flowing water of enterprises registration, by the note of different enterprises
Volume number collects the other informations such as tax flowing water, and pass through corporate body Institution Code and index national index data base.Each business
Department is by the access to respective node server, by node application program upload user information, application program can automatically by
Information is collected in system of catalogs, and the every other node of this government affairs information chain is shared to after encryption.Each department all carries out together
After the operation of sample, government data shares network system and is achieved that citizen, the comprehensive of corporate message collect.
Each business department can examine the information comprehensively by node application program typing citizen name and identification card number
Which government affairs information chain rope, system can inquire on first there are the information of the ID card No. on the index chain of the whole nation and according to awarding
Power situation feeds back each city interface to node, and node application program inquires the ID card No. in institute one by one according to the interface of feedback
There are the details of government affairs information chain, realize quick, trans-regional, interdepartmental information retrieval.Pass through node application program
Arrangement, citizen, corporate message are presented according to the pattern of license copy, and Hash of this time inquiry is tested on additional block chain
Card information prints together, can not only be used for the use of certificate copy, can also trace source so as to the true and false.It is trusty by block chain
Information is issued, and all data on block chain are respectively provided with the signature of most original publication department, can not distort, this platform is in credit
It is used in numerous business scenarios such as record queries, enterprise's certificate verification, trans-departmental proof, personal identity card examination.
The object of the invention, which is intended to establish credible government data based on block chain, shares network system, makes full use of block chain
Information can trace, the feature of shared account book, asymmetric cryptosystem shares network to build government data.It is anti-based on block chain technology
It distorts, retrospective feature, is shared applied to government data, realize believable government data sharing functionality；Based on block chain skill
The equal rights of art, the characteristics of building together, the system of catalogs of structure ownership each department realize that comprehensive data is returned with the principle of Joint construction and sharing
Collection；Based on the asymmetric cryptosystem feature of block chain technology, individually encryption is carried out to every information, and (information of every citizen has individually
Decrypted private key), prevent information leakage；The characteristics of distributed account book based on block chain technology, data are dispersed in networking
On all nodes, each node is respectively provided with full dose data and application service can be provided separately, and can be caused to avoid Single Point of Faliure
Whole system is unavailable and the problem of loss of data.Therefore the present invention is conducive to the promotion of government authority and corresponding
The confidence level of data management is more favorable to the substantial information security of the people.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although with reference to aforementioned reality
Example is applied the present invention is described in detail, it for those skilled in the art, still can be to aforementioned each implementation
Technical solution recorded in example modifies or carries out equivalent replacement to which part technical characteristic.All essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
