Example one
As shown in fig. 1, the present embodiment provides a data open sharing method based on a block chain, which includes:
s101: and extracting the required data items from the common data platform, and performing verification and calibration on the extracted data items.
Specifically, when data is needed, a data request is sent to the public data platform, and the needed data item is extracted from the public data platform. And after extraction, the data asset platform checks and calibrates the data to ensure that the data format conforms to the data fusion format, and if the format and the content do not conform to each other, an application for requesting the data again is provided for the data provider system to ensure high quality of the data.
S102: and filling the data items subjected to verification and calibration into a set template, and fusing the identity information of the social subject to form an identity document.
The method comprises the steps of generating a uniform template for each type of certificate to be generated and the like, filling extracted scattered data items from various fields of governments and economic society into the template, and fusing the extracted scattered data items into valuable data materials in government affairs services and economic activities such as certificates, contracts, certificates, bills and the like of individuals and enterprises. For example, the information such as the name, the sex identification card number, and the address of the user is fused into an identity card, as shown in fig. 2. And the electronic scanning piece similar to the paper certificate is generated by performing data fusion based on the template, so that the main body acceptance is improved.
S103: the identity document is encrypted and then sent to the block chain account corresponding to the social principal, namely, the data is returned to the owner, and meanwhile, the state of the asset is converted according to the state and state conversion rule of the pre-established intelligent contract definition data, so that the data information can be credibly circulated in all the social fields.
The right confirmation means that a block chain account is created for an individual and an enterprise through a data asset platform, digital data such as an individual and enterprise certificate and certificate formed after data fusion are encrypted and then issued to the enterprise and the individual block chain account, and data are returned to an owner.
Specifically, the identification document corresponds to one ID.
The data valuation means that through the certificate on the block chain and the certificate design intelligent contract, including the definition of digital data metadata, digital data state and state conversion rules, the operation authority of a digital data system party on digital data and the like, the circulation of the digital data is consistent with the actual data circulation process, and the transaction and circulation can be carried out in the economic activity.
After the data is validated and valuated, valuable, tradable assets are formed.
The block chain is a supporting platform for asset storage and trusted circulation, and has the characteristics of traceability, tamper resistance, loss resistance, privacy protection, denial resistance and the like. In this mode the chain of blocks provides the following functional blocks:
account creation: accounts (for storing digital material such as all certificates, etc. of individuals) may be created on the blockchain for each social principal.
In a specific implementation, 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 functions of two-dimension code display and scanning authorization of data information, and when the digital safe application platform is used in various fields of the economy and the society, a user can authorize others to use own assets in a code scanning or two-dimension code display mode like mobile payment.
Contract execution: and executing a digital data intelligent contract designed by a data asset platform, and executing a state conversion rule of the asset so that the data can be credibly circulated in all the social fields.
And data chaining, updating the data on the chain and acquiring the hash value of the data on the chain.
In specific implementation, the mode of encrypting the identification document and then sending the encrypted identification document to the block chain account of the corresponding social principal is divided into an active mode and a passive mode; the passive form is to execute the return operation after receiving the application return request of the social subject.
Various departments of the government collect various data information from the society in daily affair handling, and individuals or enterprises return data to the digital safe of a data owner in two modes of application return or active return of the government departments, and then the data owner can show and authorize data information through the digital safe.
The method comprises the steps of actively returning data information with high use frequency in life, returning identity cards, labor contracts and social security cards, and applying for returning data information which is needed in specific occasions but has low use frequency, such as vaccination information.
And the authoritative department extracts data from the public data platform through the data asset platform, fuses the data to generate certificates, and directly links and stores the certificates to the block chain account of the data owner. Then the data owner can manage and use the personal data through the digital safe box, and the intelligent contract controls the data state transition, and the specific process of the process is as follows:
and calling an opening account interface provided by the blockchain by using the data asset platform to create the blockchain account for the social agent or the enterprise without opening the blockchain account. Each social agent may have its own digital safe. And the government departments extract required data items from the public data platform through a private line and store the data items in the database. The data assets platform extracts the needed data from the database and fuses the data into formal certificates and certifications. And uploading the fused data information, namely the certificate, the certificate and the data to the block chain and storing the data information in a block chain account of the owner of the data information. The individual or enterprise logs in the digital safe box, so that the electronic certificate and certificate uploaded by the authority department in the block chain account can be checked. When the corresponding data material needs to be presented later, the digital safe box provides the authorized use token to the data demander in a two-dimensional code presentation or scanning authorization mode, and the data demander obtains the data authorized to be used by the presenter from the blockchain.
As shown in fig. 3, the process of the mode of actively returning data to the data owner in government opening data is as follows:
data extraction: the data assets platform extracts data items needed by data materials to be issued from the public data platform and stores the extracted data information into the database.
Data uplink storage: and through the data asset platform, data items stored in the database are subjected to data fusion and then stored in the account of the data owner of the block chain.
Data information acquisition: after the government stores the data material in the owner's blockchain account, the digital safe may view and manage the data material.
Data return: the data held in the government hand is returned to the hand of the data owner, so that the purpose of returning the data to the people is achieved, and the data holder and the data owner are unified.
Data circulation: when data information needs to be presented in social life, enterprises or individuals can generate two-dimensional codes through the data to be presented in the digital safe box, a data requester scans the digital safe box by using the digital safe box, namely an authorized use token corresponding to the data is acquired, and the data can be conveniently requested to acquire the data presented by a data owner from the block chain. Meanwhile, the authorized range and the state of the data material are restricted through the execution of the intelligent contract on the block chain.
The application return is a request for personal or enterprise to submit application data return in a digital safe, when the digital assets platform receives the request, the data required by a requester is extracted from a government public data platform and stored in a database and then uploaded to a requester account of a block chain, and then the data requester can check, manage and use personal data in the digital safe, and the main flow of the process is as follows:
the enterprise/individual registers and logs in the digital safe box, and applies for data return. The digital safe box interface displays the data information list which can be applied, and the applicant selects the data information required by himself. The digital safe box submits a data request to the digital assets platform according to the corresponding ID of the data material selected by the applicant. The digital assets platform responds to the request initiated by the digital safe box, calls an interface of the public data platform or directly queries a database of the public data platform according to a data list of the digital safe box request, extracts data and stores the data into the database of the digital assets platform. And the digital resource management platform takes out the extracted data from the database and assembles the data according to the asset contract. And generating a fixed hash value for the data to be linked according to an algorithm. And calling a block link interface to obtain the hash value of the data on the main body link, and performing judgment logic. If the returned hash value is null, i.e. the data information does not exist in the applicant chain, the data information ID (for example, the asset ID of the latest ID card in Zhang III) is linked up and recorded. And if the returned hash value is inconsistent with the hash value calculated at this time, namely the data material of the applicant is not the latest version, calling an update interface to update the data material in the main block chain account. If the returned hash value is consistent with the current calculation, i.e. the data has been linked and is the latest version, no operation is performed. The data applicant checks and manages the applied data in the digital safe box. Under the condition that data materials need to be displayed in government affair handling or other fields of social life, organizations, departments and enterprises are allowed to view and use personal data in an authorized use mode.
As shown in fig. 4, the process of returning the data after the individual application of the data in the government-opened data is as follows:
1. application data: the digital safe provides data information which can be applied for return in a list form.
2. Applying for data: the digital safe box applies for the required data facing the data assets platform, and the data assets platform can respond to the calling requirement of the digital safe box after receiving the application.
3. Data extraction: and after receiving the application, the data recycling platform extracts related data from the government public data platform.
4. Data local storage: data extracted from the government public data platform is stored in a database.
5. Data uplink storage: and the data assets platform extracts the data applied by the digital safe box from the database, fuses the data and then carries out uplink storage to the block chain account of the data applicant.
6. The digital safe receives: when the data assets platform carries out the chain link storage, the owner of the data information can check the data information applied by the owner through the digital safe box.
7. Data return: the data stored in the government department are returned to the hands of the data owners, and the data owners can manage the data information of the data owners by themselves.
8. Data circulation: when data information needs to be presented in social life, enterprises or individuals can generate two-dimensional codes through the data to be presented in the digital safe box, a data requester scans the digital safe box by using the digital safe box, namely an authorized use token corresponding to the data is acquired, and the data can be conveniently requested to acquire the data presented by a data owner from the block chain. Meanwhile, the authorized range and the state of the data material are restricted through the execution of the intelligent contract on the block chain.
The embodiment encrypts the identification document and sends the encrypted identification document to the block chain account corresponding to the social subject, so that the data can be returned to the owner, meanwhile, the state and state conversion rule of the data is defined according to the intelligent contract made in advance, and the state conversion of the assets is executed, so that the data information can be reliably circulated in all the social fields, the problems of privacy disclosure, data disclosure, attack on the transmission process and the like in 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 the data owner, and the individual can independently manage and use the own data assets and is responsible for the data asset disclosure.
The embodiment realizes open sharing of government data and promotes social data fusion and resource integration. And the method produces great value in the economic and social fields. The open shared data ensures that the data is reliably transferred, and information barriers, digital barriers and trust barriers are eliminated, so that social benefit maximization is realized.
