And each kind of license and certificate to be generated generates a unified template, and the extracted scattered data items from various fields of government and economic society are filled into the template to be fused into valuable license, certificate, contract, certificate, bill and other government service data materials in economic activities of individuals and enterprises. Such as fusing the information of the name, sex identification number, address, etc. of the user into an identification card, as shown in fig. 2. And the electronic scanning piece similar to the paper certificate is generated by carrying out data fusion based on the template, so that the main body receiving degree is improved.
S103: and after the identification document is encrypted, the identification document is sent to a blockchain account corresponding to the social main body, so that data is returned to an owner, and meanwhile, the state conversion of the asset is executed according to the state and state conversion rule of the intelligent contract definition data, so that the data material can be trusted in all fields of society.
The right establishing means that a blockchain account is established for individuals and enterprises through a data asset platform, digital data such as individual and enterprise license, certificate and the like formed after data fusion are encrypted and then issued to the enterprise and individual blockchain accounts, and then the data is returned to an owner.
Specifically, the identification document corresponds to one ID one by one.
The data value refers to that through license and proof design intelligent contract on the blockchain, including definition of digital data metadata, digital data state and state conversion rule, digital data operation authority of digital data main system, etc., the digital data circulation is consistent with the real data circulation process, and can be transacted and circulated in economic activity.
After the data is validated and valued, the data forms a valuable, tradable asset.
The blockchain is a supporting platform for asset storage and trusted stream, and has the characteristics of traceability, tamper resistance, loss resistance, privacy protection, repudiation resistance and the like. The functional blocks provided by the blockchain in this mode are as follows:
account creation: an account (for storing all digital material of an individual, certificate, etc.) may be created on the blockchain for each social principal.
In implementations, the account is implemented with a digital safe. The digital safe box provides an application service platform for enterprises and individuals to conveniently manage and use data assets on own blockchain accounts in a mobile phone APP or web application mode. The digital safe application platform provides the functions of two-dimension code presentation and scanning authorization of data materials, and when working in various fields of economy and society, a user can authorize other people to use own assets in a code scanning or two-dimension code presentation mode like mobile payment.

And (5) data is uplink, data on the chain is updated, and hash values of the data on the chain are acquired.
In the implementation, the mode of encrypting the identification document and then sending the encrypted identification document to the blockchain account of the corresponding social body is divided into an active mode and a passive mode; wherein, the passive form is to execute the returning operation after receiving the application returning request of the social subject.
Various data information from society is gathered by various departments of government in daily transaction, and individual or enterprise realizes data return to digital safe of data owner through application return or two modes of active return of government departments, and then the data owner can present and authorize data through the digital safe.
The method is characterized in that data materials with higher use frequency in life are actively returned, and an identity card, a labor contract and a social security card are returned, so that data materials such as vaccination information which are needed in specific occasions but are not high in use frequency are applied for returning.
The authority department extracts data from the public data platform through the data capitalization platform, fuses the data to generate certificates, and directly links and stores the certificates into the blockchain account of the data owner. The personal data can be managed and used by the data owner through the digital safe, and the intelligent contract controls the data state transition, and the specific flow of the process is as follows:
and calling an open account interface provided by the blockchain by using the data capitalization platform to create a blockchain account for a social body or enterprise of the unopened blockchain account. Each social principal may own its own digital safe. The government authorities extract the required data items from the public data platform via private lines for storage in the database. The data asset platform extracts the required data from the database and fuses the required data into formal certificates and certificates. Uploading the merged data material, namely the license, the certificate and the data to the blockchain and storing the data material on a blockchain account of a data material owner. Individuals or enterprises log in the digital safe, and can check the electronic license and certificate distributed and uploaded by the authority in the blockchain account. When the corresponding data is required to be presented later, the digital safe provides the authorized use token for the data demander in a mode of two-dimension code presentation or scanning authorization, and the data demander acquires the data authorized for use by the presenter from the blockchain.
As shown in fig. 3, the process of actively returning data to a data owner in government open data is:
and (3) data extraction: the data capitalization platform extracts data items required for issuing data materials from the public data platform and stores the extracted data information in a database.
And (3) data uplink storage: and through the data capitalization platform, data items stored in the database are stored into accounts of data owners of the blockchain after data fusion.
And (3) data acquisition: after the government stores the data material into the blockchain account of the owner, the digital safe may view and manage the data material.
Data return: the data held in the government hands are returned to the hands of the data owners, so that the owners of the data and the owners of the data are unified.
Data flow: when the social life needs to show the data, an enterprise or a person can generate a two-dimensional code through the data to be shown by the digital safe, a data requester scans the digital safe by the data requester, namely, the authorized use token corresponding to the data is obtained, and the data requester can conveniently obtain the data shown by the data owner from the blockchain. And meanwhile, the authorization range and the state of the data material are restricted by the execution of intelligent contracts on the blockchain.
The application return is a request of an individual or an enterprise for submitting application data return in the digital safe, when the digital asset platform receives the request, data required by the applicant is extracted from the government public data platform and is stored in a database and then uploaded to an applicant account of a blockchain, and then the data applicant can view, manage and use the individual data in the digital safe, and the main flow of the process is as follows:
the enterprise/person registers to log in the digital safe and applies for data material return. The digital safe interface displays the applicable data list, and the applicant selects the data required by himself. And the digital safe submits a data request to the digital asset platform according to the corresponding ID of the data material selected by the applicant. The digital asset platform responds to the request initiated by the digital safe, calls the interface of the public data platform or directly inquires the database of the public data platform according to the data list requested by the digital safe, extracts data and stores the data in the database of the digital asset platform. The digital resource management platform extracts the data from the database and assembles the data according to the asset contracts. And generating fixed hash values according to the data to be uplink and the algorithm. And calling a block link port to acquire the hash value of the data on the main chain, and judging logic. If the returned hash value is null, i.e., the data material does not exist on the applicant's chain, the data material ID (e.g., the asset ID of the latest identification card for Zhang Santa) is uploaded and recorded. And if the returned hash value is inconsistent with the calculation, that is, the data of the applicant is not the latest version, an updating interface is called to update the data in the main block chain account. If the returned hash value is consistent with the present calculation, i.e., the data has been uploaded and has been the most recent version, no operation is performed. The data applicant looks over and manages the data of the application in his own digital safe. In the context of government offices or other areas of social life where data material needs to be presented, institutions, departments, and businesses are permitted to view and use personal data by way of "authorized use".
As shown in fig. 4, the procedure of the mode of returning data after personal application data in government open data is as follows:
1. application data: the digital safe provides data materials which can be applied for returning in a list form.
2. Data application: the digital safe applies for the required data to the data asset platform, and the data asset platform can respond to the calling requirement of the digital safe after receiving the application.
3. And (3) data extraction: and the data recycling platform extracts relevant data from the government public data platform after receiving the application.
4. And (3) locally storing data: the data extracted from the government public data platform is stored in a database.
5. And (3) data uplink storage: the data capitalization platform extracts the data of the digital safe application from the database, fuses the data, and then stores the data into a blockchain account of the data applicant in a uplink manner.
6. The digital safe receives: when the data asset platform performs uplink storage, an owner of the data material can check the data material applied by the owner through the digital safe.
7. Data return: the data stored in the government authorities are returned to the hands of the data owners who can manage their own data material themselves.
8. Data flow: when the social life needs to show the data, an enterprise or a person can generate a two-dimensional code through the data to be shown by the digital safe, a data requester scans the digital safe by the data requester, namely, the authorized use token corresponding to the data is obtained, and the data requester can conveniently obtain the data shown by the data owner from the blockchain. And meanwhile, the authorization range and the state of the data material are restricted by the execution of intelligent contracts on the blockchain.
According to the embodiment, after the identification document is encrypted, the identification document is sent to the blockchain account corresponding to the social main body, namely, data is returned to an owner, meanwhile, the state and state conversion rules of the data are defined according to the preset intelligent contract, and the state conversion of the asset is executed, so that the data can be trusted in all fields of society, the problems of privacy leakage, data leakage, attack in the transmission process and the like existing under the traditional model can be avoided on the basis of realizing data sharing, the data is returned to the data owner, the data owner is realized, and the individual can independently manage and use own data asset and is responsible for own data asset leakage.
