Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
The technical scheme mainly aims at the problems that data caused by 'data island', 'data chimney' cannot circulate freely, a reasonable data sharing and circulating mechanism is lacked, control right is lost due to copying after data transaction, and the like at present, and reasonable solving measures are provided for data confirmation and data transaction based on a national industrial Internet big data center data transaction platform. The method mainly comprises the steps of data right confirmation, data non-falsification protection and data full life cycle tracing. Utilizing an identification analysis system to determine the right of the data, and determining the ownership of the data by the data owner; the non-tamperable characteristic of the blockchain technology is utilized to ensure that the transaction records of the data are not tamperable, the blockchain intelligent contract engine is utilized to ensure that the availability of the data is not visible, and each use record of the data can be traced back.
The data right-determining uses the identification analysis system to add and distribute the identification to the data, the data abstract and the related identification information are uploaded to the block chain server, and the data is broadcast after verification to ensure that the data cannot be tampered. The data user obtains summary information and identification information of the data by accessing the data service interface, obtains an access path of the data by the identification analysis service, obtains original data by an intelligent contract engine after the data user accords with related intelligent contract rules, calculates and generates new result data, distributes identification to the result data, forms a tracing record for the use condition of the original data and the new result data, and uploads the tracing record to the blockchain server, and finally returns the result data to the data user.
As shown in fig. 1, the data interaction mode of the data transaction platform of the present invention is:
1. the identification analysis system registers the data which the data owner applies for registration, distributes a data identification ID1, generates a data abstract A1, uploads identification information ID1 and abstract information A1 to the blockchain platform, and the abstract information comprises data identification analysis metadata such as a data access path, a use rule, authentication information and the like, verifies and broadcasts the data identification analysis metadata, and completes data ownership confirmation and data non-falsifiability protection.
2. The use of data D1 by the blockchain-based intelligence contracts configures related usage rules.
3. When a data user generates a data use requirement, the data service interface is accessed, the identification analysis system is called, abstract information A1 of the identification information ID1 is returned, a query request is sent to the identification analysis system according to the identification information, and the identification analysis system returns a data access path to the intelligent contract engine.
4. After the data consumer satisfies the conditions of the smart contract, the authentication information of the data of the identification information ID1 is obtained from the blockchain. When the data D1 exists inside the own system, the authentication information is generally a token, a key, etc., and when the data D1 is stored in the third party platform, the authentication information is used by the smart contract engine to obtain the original data of the data D1 from the third party platform.
5. The intelligent contract engine acquires the source data D1 according to the data access path and the authentication information (used for a third party platform) of the data, and according to the setting of the intelligent contract, the data owner allows the data user to acquire the data D1, and then the data D1 is directly returned to the data user.
For example, the D1 raw data is the fan current 15A, which the data user wants to use by a certain enterprise, or 15A is directly returned to the enterprise, and the enterprise calculates 220×15a=3.3kw; where the original data is directly copied to the data consumer.
Alternatively, after the smart contract engine takes 15A, the engine calculates 3.3KW (this is the result data D2); finally, the 3.3KW is returned to the data user. In this way, the original data 15A is protected from being copied and the data consumer obtains his intended result. )
6. The data owner is not allowed to return the source data D1, and the smart contract engine is used to calculate the result data D2 according to the contract rules. That is, if the data owner does not allow the data consumer to obtain the data D1, the smart contract engine calculates the result D2 using D1, returns D2 to the data consumer, and finally clears D1, thereby achieving the effect that the data D1 can be used, but cannot be directly copied.
7. The identification analysis system registers the new result data D2 and distributes the data identification ID2 to generate a data abstract A2, a data access path and other identification analysis metadata.
8. And uploading the identification information ID2, the abstract information A2, the use record of the data D1 and the traceability relationship between the result data D2 and the original data D1 to a certification chain of the blockchain platform.
9. The result data D2 is returned to the data consumer.
10. And finally, completing the whole transaction process of the data. The whole transaction process ensures the non-falsifiability, traceability and full life cycle management of the data.
Although the specific details, algorithms for implementation, and figures of the present invention have been disclosed for illustrative purposes to aid in understanding the contents of the present invention and the implementation thereof, it will be appreciated by those skilled in the art that: various alternatives, variations and modifications are possible without departing from the spirit and scope of the invention and the appended claims. The invention should not be limited to the preferred embodiments of the present description and the disclosure of the drawings, but the scope of the invention is defined by the claims.
