The application environment and the hardware structure and function of the related devices of the various embodiments of the present invention have been described in detail so far. Hereinafter, various embodiments of the present invention will be proposed based on the above-described application environment and related devices.
First, the present invention provides a data sharing system 200.
Referring to FIG. 3, a program module diagram of the first embodiment of the data sharing system 200 according to the present invention is shown.
In this embodiment, the data sharing system 200 includes a series of computer program instructions stored on the memory 11, which when executed by the processor 12, may implement the data sharing operations of the embodiments of the present invention. In some embodiments, the data sharing system 200 may be divided into one or more modules based on the particular operations implemented by the portions of the computer program instructions. For example, in fig. 2, the data sharing system 200 may be divided into a receiving module 201, a generating module 202, a verifying module 203, and a sending module 204. Wherein:
the receiving module 201 is configured to receive a data sharing application of a data requesting party.
Specifically, the present embodiment describes the data sharing system in detail by taking data sharing during enterprise financing as an example. Firstly, a data sharing application of a data requester is received, wherein the data sharing application is used for requesting to query data related to a data authorizer, and at the moment, the data sharing application can obtain a service authorization code. In this embodiment, the data requesting party is a financial institution (e.g., a bank), the receiving requesting party is a government affair big data open platform, and the data authorizing party is an enterprise (e.g., a small and medium-sized micro enterprise). The financial institution applies for a business authorization code from the government big data open platform to query data related to a certain enterprise, thereby verifying whether the enterprise can be credited. The data is mainly publicity data provided by government offices (such as industrial and commercial companies, courts and the like) and is stored in a data lake of the blockchain. The financial institution can check the required data in the government affair big data open platform and select the application service life.
The generating module 202 is configured to generate a data sharing protocol according to the data sharing application and the intelligent contract, and return a service authorization code to the data requester.
Specifically, after receiving the data sharing application, a data sharing protocol may be generated according to an intelligent contract template, the data sharing protocol is uploaded and stored in a block chain, and a corresponding service authorization code is returned to the data requester. The service authorization code is a two-dimensional code generated in real time at present, and the corresponding data sharing protocol can be associated through the service authorization code subsequently. The content of the data sharing protocol can be set in a self-defining way according to the actual application scene, and mainly the content of constraint indexes such as a data opening main body (such as a related commission office), a data using main body (such as a financial institution like a bank), a data range and a service life is determined.
In this embodiment, after receiving the data sharing application submitted by the financial institution, the government affair big data open platform sends indexes such as a bank name, a requested open data range, a requested open service life and the like to the government affair public service platform, and then the government affair public service platform returns a URL with parameters to feed back the index content to the government affair big data open platform. And the government affair big data open platform generates a data sharing protocol according to the intelligent contract template, and simultaneously links the protocol for storing certificates and returns a new service authorization code to the financial institution.
Through the intelligent contract technology, the data sharing agreement signing of the financial institution and each government agency can be realized, and a large amount of labor, material resources and time cost are reduced. And all protocols are linked up for storing certificates, so that protocol data cannot be tampered, and data safety is guaranteed.
The receiving module 201 is further configured to receive a service authorization code and authorization information provided by a data authorizer.
Specifically, the data requestor provides the service authorization code to the data authorizer, and the data authorizer can grant the authorization by scanning the service authorization code. In this embodiment, the data authorizer is an enterprise legal person. After the enterprise legal person finishes enterprise registration and authentication on the government affair public service platform, the enterprise legal person agrees to authorize the financial institution by scanning the business authorization code issued by the financial institution. And the government affair public service platform obtains enterprise authorization, and uploads and stores the authorization information into the block chain. The authorization information comprises a data opening main body, a data using main body, a data range, a service life and the like.
Because the government affair public service platform is generally a platform which is built for the leading of the government department and is guaranteed by government endorsements, the successful registration of an enterprise on the platform indicates that the government department approves the identity of the enterprise, and the identity of the enterprise is real. This embodiment is through the official affairs public service platform endorsement, proves the authenticity of authorizing the enterprise identity, is favorable to reducing the risk that financial institution handled the business, makes the credit endorsement of enterprise promote. Meanwhile, the government affair public service platform is used as a platform with public credibility for a third party to link the enterprise authorization information, and can play a fair and fair role in the data request party and the data authorization party (enterprises and banks).
The checking module 203 is configured to perform contract checking according to the authorization information and the data sharing protocol.
Specifically, after receiving a request of the data requesting party for data sharing and obtaining an authorization granted by the data authorizing party, contract verification needs to be performed according to the authorization information and the data sharing protocol, the requested data can be provided to the data requesting party only after the verification is passed, otherwise, the data sharing cannot be performed due to the failure of the authorization. The contract verification mainly judges whether the authorization information conforms to each index in the data sharing protocol, and if the authorization information conforms to each index in the data sharing protocol, the contract verification is passed.
In the embodiment, the government affair public service platform initiates a data query request to the government affair data open gateway to request to query the authorized public data of the enterprise, and the data interacts with the data lake through the open gateway. And the open gateway judges whether to provide related data or not through contract verification between the data sharing protocol and the authorization information. Specifically, it is necessary to check whether the contents of the agreement contents signed by the financial institution before and the authorization information of the enterprise are consistent, including the data use subject, the data range, and the like, and if the contents of the agreement contents exceed the contents of the agreement, the agreement contents do not meet the authorization approval requirements, and each index of the authorization information must be within the agreement range.
It is noted that since both the data sharing protocol and the authorization information are stored in uplink, the contract check can be accomplished by trading the consistency of the data sharing protocol and the authorization information over blockchains.
The embodiment can ensure that the authorized content of the enterprise is consistent with the content of the data sharing protocol of the financial institution, and ensure that the data does not have more authorized field so as to ensure the safety of the data.
The sending module 204 is configured to read related data from the block chain and send the data to the data requestor after the check is passed.
Specifically, if the check passes, the requested data is read from the data lake of the blockchain and returned to the data requester. For example, the enterprise-related data is read and returned to the financial institution.
The data sharing system provided by this embodiment may automatically generate a data sharing protocol with a data requesting party, obtain authorization of the data authorizing party by providing a service authorization code, associate authorization information with the data sharing protocol, and return authorized data to the data requesting party after the authorization information and the data sharing protocol are verified, thereby implementing accurate authorization and sharing of data.
In the specific general financial scene, the general financial business can be completed only by scanning the code once by a corporate legal person, excessive paper materials do not need to be submitted, business requirements are known, and the business handling of enterprises (particularly small and medium enterprises) is facilitated. The financial institution can acquire the related data of authorized enterprises through the protocol signed by each committee office to complete the acceptance of general financial services, and meanwhile, the identity of an applied enterprise is ensured to be real and the data of the enterprise is real through the endorsement of a government affair public service platform, so that the risk of the financial institution is reduced, and the financial service is better provided for the enterprise. For governments, conditionally opening public data helps to help enterprise development and promote social and economic development, meanwhile, by means of a block chain technology, data privacy safety can be guaranteed, accurate authorization of data is achieved due to the fact that a field is not opened much, and data privacy safety is fully guaranteed.
Referring to FIG. 4, a program module diagram of a data sharing system 200 according to a second embodiment of the present invention is shown. In this embodiment, the data sharing system 200 further includes a recording module 205 in addition to the receiving module 201, the generating module 202, the verifying module 203, and the sending module 204 in the first embodiment.
The recording module 205 is configured to record an authorization query behavior log and upload the authorization query behavior log to a block chain.
Specifically, the authorization query behavior log includes a data opening body, a data using body, a query time, a data range, and the like, and is uploaded and stored in the block chain. In this embodiment, the open gateway chains and stores the chain certificate and stamps a time stamp on the authorization query behavior log, so as to facilitate subsequent data tracing.
Alternatively, the financial institution may generate some data related to the business during the period of providing the business with the popular financial business, and the financial institution may back feed the data to the government department to expand the portrait data related to the business so that the business data becomes more and more accurate.
The data sharing system provided by this embodiment may automatically generate a data sharing protocol with a data requesting party, obtain authorization of the data authorizing party by providing a service authorization code, associate authorization information with the data sharing protocol, and return authorized data to the data requesting party after the authorization information and the data sharing protocol are verified, thereby implementing accurate authorization and sharing of data.

Specifically, the data requestor provides the service authorization code to the data authorizer, and the data authorizer can grant the authorization by scanning the service authorization code. In this embodiment, the data authorizer is an enterprise legal person. After the enterprise legal person finishes enterprise registration and authentication on the government affair public service platform, the enterprise legal person agrees to authorize the financial institution by scanning the business authorization code issued by the financial institution. And the government affair public service platform obtains enterprise authorization, and uploads and stores the authorization information into the block chain. The authorization information comprises a data opening main body, a data using main body, a data range, a service life and the like.
Because the government affair public service platform is generally a platform which is built for the leading of the government department and is guaranteed by government endorsements, the successful registration of an enterprise on the platform indicates that the government department approves the identity of the enterprise, and the identity of the enterprise is real. This embodiment is through the official affairs public service platform endorsement, proves the authenticity of authorizing the enterprise identity, is favorable to reducing the risk that financial institution handled the business, makes the credit endorsement of enterprise promote. Meanwhile, the government affair public service platform is used as a platform with public credibility for a third party to link the enterprise authorization information, and can play a fair and fair role in the data request party and the data authorization party (enterprises and banks).
Step S406, contract verification is carried out according to the authorization information and the data sharing protocol.
Specifically, after receiving a request of the data requesting party for data sharing and obtaining an authorization granted by the data authorizing party, contract verification needs to be performed according to the authorization information and the data sharing protocol, the requested data can be provided to the data requesting party only after the verification is passed, otherwise, the data sharing cannot be performed due to the failure of the authorization. The contract verification mainly judges whether the authorization information conforms to each index in the data sharing protocol, and if the authorization information conforms to each index in the data sharing protocol, the contract verification is passed.
In the embodiment, the government affair public service platform initiates a data query request to the government affair data open gateway to request to query the authorized public data of the enterprise, and the data interacts with the data lake through the open gateway. And the open gateway judges whether to provide related data or not through contract verification between the data sharing protocol and the authorization information. Specifically, it is necessary to check whether the contents of the agreement contents signed by the financial institution before and the authorization information of the enterprise are consistent, including the data use subject, the data range, and the like, and if the contents of the agreement contents exceed the contents of the agreement, the agreement contents do not meet the authorization approval requirements, and each index of the authorization information must be within the agreement range.
It is noted that since both the data sharing protocol and the authorization information are stored in uplink, the contract check can be accomplished by trading the consistency of the data sharing protocol and the authorization information over blockchains.
The embodiment can ensure that the authorized content of the enterprise is consistent with the content of the data sharing protocol of the financial institution, and ensure that the data does not have more authorized field so as to ensure the safety of the data.
In step S408, after the verification is passed, the relevant data is read from the blockchain and sent to the data requestor.
Specifically, if the check passes, the requested data is read from the data lake of the blockchain and returned to the data requester. For example, the enterprise-related data is read and returned to the financial institution.
The data sharing method provided by this embodiment may automatically generate a data sharing protocol with a data requesting party, obtain authorization of the data authorizing party by providing a service authorization code, and associate authorization information with the data sharing protocol, and when the authorization information and the data sharing protocol are verified, may return authorized data to the data requesting party, thereby implementing accurate authorization and sharing of data.
In the specific general financial scene, the general financial business can be completed only by scanning the code once by a corporate legal person, excessive paper materials do not need to be submitted, business requirements are known, and the business handling of enterprises (particularly small and medium enterprises) is facilitated. The financial institution can acquire the related data of authorized enterprises through the protocol signed by each committee office to complete the acceptance of general financial services, and meanwhile, the identity of an applied enterprise is ensured to be real and the data of the enterprise is real through the endorsement of a government affair public service platform, so that the risk of the financial institution is reduced, and the financial service is better provided for the enterprise. For governments, conditionally opening public data helps to help enterprise development and promote social and economic development, meanwhile, by means of a block chain technology, data privacy safety can be guaranteed, accurate authorization of data is achieved due to the fact that a field is not opened much, and data privacy safety is fully guaranteed.
Fig. 6 is a schematic flow chart of a data sharing method according to a second embodiment of the present invention. In this embodiment, steps S500 to S508 of the data sharing method are similar to steps S400 to S408 of the first embodiment, except that the method further includes step S510.
The method comprises the following steps:
step S500, receiving a data sharing application of a data requester.
Specifically, the present embodiment describes the data sharing system in detail by taking data sharing during enterprise financing as an example. Firstly, a data sharing application of a data requester is received, wherein the data sharing application is used for requesting to query data related to a data authorizer, and at the moment, the data sharing application can obtain a service authorization code. In this embodiment, the data requesting party is a financial institution (e.g., a bank), the receiving requesting party is a government affair big data open platform, and the data authorizing party is an enterprise (e.g., a small and medium-sized micro enterprise). The financial institution applies for a business authorization code from the government big data open platform to query data related to a certain enterprise, thereby verifying whether the enterprise can be credited. The data is mainly publicity data provided by government offices (such as industrial and commercial companies, courts and the like) and is stored in a data lake of the blockchain. The financial institution can check the required data in the government affair big data open platform and select the application service life.
Step S502, a data sharing protocol is generated according to the data sharing application and the intelligent contract, and a service authorization code is returned to the data requesting party.
Specifically, after receiving the data sharing application, a data sharing protocol may be generated according to an intelligent contract template, the data sharing protocol is uploaded and stored in a block chain, and a corresponding service authorization code is returned to the data requester. The service authorization code is a two-dimensional code generated in real time at present, and the corresponding data sharing protocol can be associated through the service authorization code subsequently. The content of the data sharing protocol can be set in a self-defining way according to the actual application scene, and mainly the content of constraint indexes such as a data opening main body (such as a related commission office), a data using main body (such as a financial institution like a bank), a data range and a service life is determined.
In this embodiment, after receiving the data sharing application submitted by the financial institution, the government affair big data open platform sends indexes such as a bank name, a requested open data range, a requested open service life and the like to the government affair public service platform, and then the government affair public service platform returns a URL with parameters to feed back the index content to the government affair big data open platform. And the government affair big data open platform generates a data sharing protocol according to the intelligent contract template, and simultaneously links the protocol for storing certificates and returns a new service authorization code to the financial institution.
Through the intelligent contract technology, the data sharing agreement signing of the financial institution and each government agency can be realized, and a large amount of labor, material resources and time cost are reduced. And all protocols are linked up for storing certificates, so that protocol data cannot be tampered, and data safety is guaranteed.
Step S504, a service authorization code and authorization information provided by the data authorizer are received.
Specifically, the data requestor provides the service authorization code to the data authorizer, and the data authorizer can grant the authorization by scanning the service authorization code. In this embodiment, the data authorizer is an enterprise legal person. After the enterprise legal person finishes enterprise registration and authentication on the government affair public service platform, the enterprise legal person agrees to authorize the financial institution by scanning the business authorization code issued by the financial institution. And the government affair public service platform obtains enterprise authorization, and uploads and stores the authorization information into the block chain. The authorization information comprises a data opening main body, a data using main body, a data range, a service life and the like.
Because the government affair public service platform is generally a platform which is built for the leading of the government department and is guaranteed by government endorsements, the successful registration of an enterprise on the platform indicates that the government department approves the identity of the enterprise, and the identity of the enterprise is real. This embodiment is through the official affairs public service platform endorsement, proves the authenticity of authorizing the enterprise identity, is favorable to reducing the risk that financial institution handled the business, makes the credit endorsement of enterprise promote. Meanwhile, the government affair public service platform is used as a platform with public credibility for a third party to link the enterprise authorization information, and can play a fair and fair role in the data request party and the data authorization party (enterprises and banks).
Step S506, contract checking is carried out according to the authorization information and the data sharing protocol.
Specifically, after receiving a request of the data requesting party for data sharing and obtaining an authorization granted by the data authorizing party, contract verification needs to be performed according to the authorization information and the data sharing protocol, the requested data can be provided to the data requesting party only after the verification is passed, otherwise, the data sharing cannot be performed due to the failure of the authorization. The contract verification mainly judges whether the authorization information conforms to each index in the data sharing protocol, and if the authorization information conforms to each index in the data sharing protocol, the contract verification is passed.
In the embodiment, the government affair public service platform initiates a data query request to the government affair data open gateway to request to query the authorized public data of the enterprise, and the data interacts with the data lake through the open gateway. And the open gateway judges whether to provide related data or not through contract verification between the data sharing protocol and the authorization information. Specifically, it is necessary to check whether the contents of the agreement contents signed by the financial institution before and the authorization information of the enterprise are consistent, including the data use subject, the data range, and the like, and if the contents of the agreement contents exceed the contents of the agreement, the agreement contents do not meet the authorization approval requirements, and each index of the authorization information must be within the agreement range.
It is noted that since both the data sharing protocol and the authorization information are stored in uplink, the contract check can be accomplished by trading the consistency of the data sharing protocol and the authorization information over blockchains.
The embodiment can ensure that the authorized content of the enterprise is consistent with the content of the data sharing protocol of the financial institution, and ensure that the data does not have more authorized field so as to ensure the safety of the data.
In step S508, after the verification is passed, the relevant data is read from the blockchain and sent to the data requestor.
Specifically, if the check passes, the requested data is read from the data lake of the blockchain and returned to the data requester. For example, the enterprise-related data is read and returned to the financial institution.
Step S510, recording an authorization query behavior log and uploading the log to a block chain.
Specifically, the authorization query behavior log includes a data opening body, a data using body, a query time, a data range, and the like, and is uploaded and stored in the block chain. In this embodiment, the open gateway chains and stores the chain certificate and stamps a time stamp on the authorization query behavior log, so as to facilitate subsequent data tracing.
Alternatively, the financial institution may generate some data related to the business during the period of providing the business with the popular financial business, and the financial institution may back feed the data to the government department to expand the portrait data related to the business so that the business data becomes more and more accurate.
