However, the inventor realizes that if the information and data sharing is not in place, information asymmetry may result, which may affect subsequent applications. If information and data sharing is too easy, data leakage may occur, resulting in data security problems.

For example, the problems of difficult, expensive and slow financing for small and medium-sized enterprises are still prominent today. One of the fundamental reasons for the above problems is that small and medium-sized enterprises have excessive business risks, such as small scale, lack of sufficient mortgage assets, unstable operation and The governance structure is not standardized, and most of them do not meet the loan conditions of financial institutions. Moreover, the problem of information asymmetry makes it difficult for financial institutions to accurately identify the credit risks of small and medium-sized enterprises, and cannot break the bottleneck of mortgage and guarantee for small and medium-sized enterprises. For financial institutions, there are problems such as incomplete pre-loan data, inefficient approval during lending, and untimely post-loan monitoring. Financial institutions generally rely on manual pre-loan investigations, and the average investigation cycle is long; at the same time, financial institutions lack centralized and reliable data query channels, and data such as industry and commerce, courts, mortgages and pledges need to be queried separately in different departments and their websites, which is time-consuming It is labor-intensive, but there is still the problem of missing data, which reduces the efficiency of approval; in the post-loan management part, most financial institutions have the problem of lack of real-time data, and rely on manual door-to-door due diligence, which is not conducive to the risk control ability and efficiency of financial institutions promote. In addition, for government departments, if data is shared externally, there may be data leakage privacy and data security issues.

Therefore, how to provide a simple and safe data sharing solution while overcoming the above deficiencies has become an urgent technical problem to be solved.

Hereinafter, various embodiments of the present application will be proposed based on the above-mentioned application environment and related devices.

First, the present application proposes a data sharing system 200 .

Referring to FIG. 3 , it is a program module diagram of the first embodiment of the data sharing system 200 of the present application.

In this embodiment, the data sharing system 200 includes a series of computer program instructions stored in the memory 11 . When the computer program instructions are executed by the processor 12 , the data sharing operations of the embodiments of the present application can be implemented. In some embodiments, data sharing system 200 may be divided into one or more modules based on the particular operations implemented by the various portions of the computer program instructions. For example, in FIG. 2 , the data sharing system 200 can be divided into a receiving module 201 , a generating module 202 , a checking module 203 , and a sending module 204 . in:

The receiving module 201 is configured to receive a data sharing application from a data requester.

Specifically, in this embodiment, the data sharing system is described in detail by taking the data sharing during enterprise financing as an example. First, a data sharing application from a data requester is received. The data sharing application is for requesting to query data related to the data authorizer. At this time, the data sharing application can obtain a service authorization code. In this embodiment, the data requester is a financial institution (for example, a bank), the receiving requester is an open platform for government affairs big data, and the data authorizer is an enterprise (for example, a small, medium, and micro enterprise). Financial institutions apply for business authorization codes from the government affairs big data open platform to query data related to a certain enterprise, so as to check whether they can lend money to the enterprise. Among them, the data are mainly public data provided by various government commissions and offices (such as industry and commerce, courts, etc.), which are stored in the data lake of the blockchain. Financial institutions can select the required data in the government affairs big data open platform and choose the application period.

The generating module 202 is configured to generate a data sharing agreement according to the data sharing application and the smart contract, and return a service authorization code to the data requester.

Specifically, after receiving the data sharing application, a data sharing agreement can be generated according to the smart contract template, the data sharing agreement can be uploaded and saved to the blockchain, and a corresponding business authorization code can be returned to the data requester . The service authorization code is a two-dimensional code currently generated in real time, and the corresponding data sharing protocol can be associated with the service authorization code subsequently. The content of the data sharing agreement can be customized according to the actual application scenario, mainly to determine the data opening subject (such as relevant commissions, offices and bureaus), data users (such as banks and other financial institutions), data scope, use period, etc. Indicator content.

In this embodiment, after receiving the data sharing application submitted by the financial institution, the government affairs big data open platform sends the bank name, the requested open data scope, usage period and other indicators to the government affairs public service platform, and then the government affairs public service platform The platform feeds back the above indicators to the government big data open platform by returning a URL with parameters. The government affairs big data open platform generates a data sharing agreement according to the smart contract template, and at the same time, the agreement is stored on the chain, and a new business authorization code is returned to the financial institution.

Through smart contract technology, data sharing agreements between financial institutions and government agencies and bureaus can be signed, reducing a lot of manpower, material resources and time costs. Moreover, all protocols are stored on the chain, making the protocol data immutable and ensuring data security.

The receiving module 201 is further configured to receive the service authorization code and authorization information provided by the data authorizer.

Specifically, the data requester provides the service authorization code to the data authorizer, and the data authorizer can agree to the authorization by scanning the service authorization code. In this embodiment, the data authorizer is an enterprise legal person. After completing the enterprise registration and authentication on the government affairs public service platform, the legal person of the enterprise agrees to authorize the financial institution by scanning the business authorization code issued by the financial institution. The government affairs public service platform is authorized by the enterprise, and the authorization information is uploaded and saved to the blockchain. The authorization information includes the subject of data opening, the subject of data use, the scope of data, the period of use, and the like.

Since the government affairs public service platform is generally a platform led by the government department, it is guaranteed by the government's endorsement. Therefore, the successful registration of an enterprise on the platform means that the government department recognizes the identity of the enterprise, and the enterprise identity is real. This embodiment proves the authenticity of the identity of the authorized enterprise through the endorsement of the government affairs public service platform, which is beneficial to reduce the risk of the financial institution handling business and improve the enterprise credit endorsement. At the same time, the government affairs public service platform, as a credible third-party platform, uploads the enterprise authorization information to the chain, which can play a fair and just role for the data requester and data authorizer (enterprise and bank).

The verification module 203 is configured to perform contract verification according to the authorization information and the data sharing protocol.

Specifically, after receiving the request of the data requester for data sharing and obtaining the consent of the data authorizer, the contract verification needs to be carried out according to the authorization information and the data sharing agreement, and the verification can only be sent to the The data requester provides the requested data, otherwise the authorization fails and data sharing cannot be performed. The contract verification is mainly to determine whether the authorization information is consistent with each index in the data sharing agreement, and if all are consistent, the verification is passed.

In this embodiment, the government affairs public service platform initiates a data query request to the government affairs data open gateway to request to query the openable data authorized by the enterprise, and these data interact with the data lake through the open gateway. The open gateway judges whether to provide relevant data through the contract verification between the data sharing protocol and the authorization information. Specifically, it is necessary to verify whether the content of the agreement signed by the financial institution before and the content of the authorization information of the enterprise are consistent, including the subject of data use, the scope of the data, etc. Item indicators must be within the scope of the agreement.

It is worth noting that since the data sharing agreement and the authorization information have been saved on the chain, the contract verification can be completed by transacting the consistency of the data sharing agreement and the authorization information on the blockchain .

This embodiment can ensure that the content authorized by the enterprise is consistent with the content in the data sharing agreement of the financial institution, and ensure that no more than one field is authorized in the data, so as to ensure the security of the data.

The sending module 204 is configured to read the relevant data from the blockchain and send it to the data requester after the verification is passed.

Specifically, if the verification is passed, the requested data is read from the data lake of the blockchain and returned to the data requester. For example, read the relevant data of the enterprise and return it to the financial institution.

The data sharing system provided in this embodiment can automatically generate a data sharing agreement with the data requester, obtain the authorization of the data authorizer by providing the service authorization code, and associate the authorization information with the data sharing agreement. After the authorization information and the data sharing protocol are verified, the authorized data can be returned to the data requester to realize accurate authorization and sharing of data.
