Referring to fig. 3, a schematic flow chart of a data processing method based on a block chain according to an embodiment of the present invention is shown, where the data processing method based on a block chain is applied to the shared switching platform shown in fig. 1 in the above embodiment, and the data processing method based on a block chain mainly includes the following steps:
step S301: and the sharing exchange platform acquires the data sharing demand information determined by the data demander based on the authorized data directory and sends the data sharing demand information to the data provider.
In step S301, the data sharing switching platform obtains data sharing requirement information issued by the pre-established data sharing switching model of the data demander based on the authorized data directory.
The data demand side performs user registration of the data demand side and creation of a data sharing exchange model of the data demand side through the data exchange sharing front-end.
The created data sharing exchange model of the data demand side is published through the blockchain platform, and no privacy disclosure problem exists because specific data are not involved in the model.
The data sharing exchange model of the data demander comprises a data exchange rule of the data demander, data field description of the data demander and data privacy authority setting of the data demander, wherein the data privacy authority setting of the data demander can be granular to a data field level (namely, data corresponding to the data field of each data demander can be exchanged to a data provider, and the data field of each data demander can be configured independently), and a basis is established for realizing data sharing exchange with the data provider according to a data sharing principle (full disclosure, conditional disclosure, directional disclosure and the like) of the data demander.
And the data directory for right confirmation is obtained by uploading the data directory to be right confirmed to a block chain platform in advance by a data provider for chain storage on a block chain.
The data provider completes the structuring and the entry of the data by establishing the data directory to be authorized, and performs chain link certification on the combined and the entry data directory to be authorized, so as to complete the authorization of the data directory.
The data directory authority determination mainly has the functions of verifying the legal compliance of data and performing a series of verification, registration and authentication on a data production and processing service subject, a data circulation process and a data circulation application rule.
The data directory may be a personal data directory such as a member number, a sex, an age group, a credit rating, etc., or an equipment directory such as a list name of a test, an equipment number, a test item, etc.
The data provider may be an internet platform, a medical facility, or other system that produces electronic data, etc.
Step S302: and the sharing exchange platform receives the data sharing supply information determined by the data supply party based on the data sharing demand information.
In step S302, the sharing exchange platform receives the data sharing provision information issued by the pre-established data sharing exchange model of the data provider based on the data sharing requirement information.
The data provider registers a user of the data provider and creates a data sharing exchange model of the data provider through the data exchange sharing front-end.
The created data sharing exchange model of the data provider is published through the blockchain platform, and no privacy disclosure problem exists because specific data are not involved in the model.
The data sharing exchange model of the data provider comprises a data exchange rule of the data provider, data field description of the data provider and data privacy authority setting of the data provider, wherein the data privacy authority setting of the data provider can be granular to a data field level (namely, data corresponding to the data field of each data provider can be exchanged to a data demander, and the data field of each data provider can be configured independently), and a basis is established for realizing data sharing exchange with the data demander according to a data sharing principle (full disclosure, conditional disclosure, directional disclosure and the like) of the data provider.
Step S303: and the sharing exchange platform generates an intelligent contract based on the preset charging standard, the data sharing provision information and the data sharing requirement information.
In step S303, the preset charging standard is defined according to a specific scenario of the data sharing exchange, the scenario of the data sharing exchange is different, and the corresponding charging standard is also different.
The setting of the preset charging standard is set by a technician according to the actual situation, and the invention is not particularly limited.
An intelligent contract is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
Step S304: the sharing exchange platform performs data sharing exchange requirement matching on the data sharing providing information and the data sharing requirement information based on the intelligent contract, and judges whether the data sharing exchange requirement matching is successful, if so, step S305 is executed, and if not, step S307 is executed.
In step S304, the data sharing and exchanging requirement matching method converts the data field corresponding to the data sharing provision information defined by the data sharing and exchanging model of the data provider into a text to obtain a data sharing and exchanging model text set of the data provider, converts the data field corresponding to the data sharing requirement information defined by the data sharing and exchanging model of the data requester into a text to obtain a data sharing and exchanging model text set of the data requester, and then performs text matching on the data sharing and exchanging model text set of the data provider and the data requester by using a text matching algorithm, and the matching result meets the preset condition and is locked as two or more parties achieving the matching.
Step S305: and the sharing exchange platform generates a data sharing exchange result.
In step S305, the data sharing exchange result is the data sharing exchange data successfully matched between the data provider and the data demander.
Step S306: and the shared exchange platform executes the transaction of the data provider and the data demander according to a preset transaction rule and a data shared exchange result, and uploads the transaction result to the block chain platform for uploading and storing the certificate.
In step S306, the sharing exchange platform executes the transaction between the data provider and the data consumer by using the transaction credit in the blockchain according to the value generated by the data provider due to the data sharing exchange result.
