Embodiment 1

[0026] A distributed data fusion platform based on blockchain70, please refer to the attached figure 1 , including: several data storage stations 20, respectively connected to multiple data sources 10, receiving the original data submitted by the data sources 10, associating the original data with the data sources 10, encrypting and storing them, and extracting the hash value of the original data 210, associate the data source party 10 with the identification and upload it to the blockchain 70 for storage; the summary server 50 is connected to the data source party 10 and the data demander 60, and the data source party 10 will generate description summaries and example data for the data it owns, and will describe The summary and example data are submitted to the summary server 50 for disclosure, and the data demander 60 checks the description summary disclosed by the summary server 50 to find the data of the required data source 10; the model server 30 is connected to the data ...

Embodiment 2

[0062] A distributed data fusion platform based on block chain 70. On the basis of Embodiment 1, this embodiment further improves the way data storage nodes 21 execute data processing model 31, so as to improve the protection of data privacy . The data distribution node 22 distributes each data row 211 to several data storage nodes 21. When distributing, the data distribution node 22 splits the value of the numeric field in the data row 211 into data that matches the number of data storage nodes 21. Several addends are assigned to a data storage node 21 as the value of the corresponding numerical field. When several data storage nodes 21 execute the data processing model 31, a secure multi-party calculation is established to obtain the value of the data processing model 31. The output volume is 312.

[0063] Furthermore, in this embodiment, when the data distribution node 22 distributes each data row 211 to several data storage nodes 21, the steps include:

Abstract

The present invention relates to the technical field of block chain, in particular to a distributed data fusion platform based on block chain, including: several data storage stations, receiving the original data submitted by the data source, and after the original data is associated with the data source Encrypted storage; summary server, which generates description summaries and sample data, and submits description summaries and sample data to the summary server for disclosure; model server, where the data requester submits the data processing model to the model server; transaction server, where the data requester submits the corresponding data row The token is transferred to the designated account, and the easy server notifies the model server to send it to the data storage station of the corresponding data source. The data storage station executes the data model, sends the execution result to the data demander through the transaction server, and transfers the corresponding token to the data storage station at the same time. source account. The substantive effect of the present invention is: the benefit of the data source is guaranteed by using the token payment on the block chain, and data security and privacy are effectively protected.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a distributed data fusion platform based on block chains. Background technique [0002] With the development of information technology, people's life is increasingly inseparable from the guidance of information. At the same time, people generate more and more data in their daily lives. These data are generated and stored in online shopping platforms, banks, interest websites, APPs, government agencies, etc. Due to interests and privacy protection issues, these data are scattered in various institutions and enterprises, forming information islands one by one. With the rise and development of big data technology, the value of data can be more and more mined and used. Based on the application of big data technology, it can bring huge benefits and convenience to people, reduce social operating costs, and improve life experience. Such as traffic planning, product recommendati...
