Abstract

The invention relates to a block chain-based data management method and a block chain system. The method includes: broadcasting a request of a data transaction with a demanded-side node by a demanding-side node through a block chain network, wherein the request of the data transaction includes transaction attribute data; acquiring the request of the data transaction by the demanded-side node through the block chain network, and sending a transaction response request, which corresponds to the request of the data transaction, to the block chain network according to the transaction attribute data of the request of the data transaction, wherein the transaction response request includes response attribute data, and the response attribute data includes a data identifier; and acquiring the response attribute data in the transaction response request by the demanding-side node through the block chain network, then determining the data identifier in the response attribute data, and downloading data, which correspond to the data identifier, from a preset data trusteeship server according to the determined data identifier. The method improves the security of data transactions and storage.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a block chain-based data management method and a block chain system. Background technique [0002] At present, when many companies develop preset types of data analysis systems (for example, automatic license plate recognition systems, insurance anti-fraud systems, etc.), they need to obtain a large amount of sample data for relevant model training, and most of the current sample data They are all scattered and stored in different places, and when data is needed for training, it is necessary to download data from various places. There may be some of these data that need to be charged, and it takes a lot of time to jump to different websites for payment. [0003] Although there is currently a solution in the industry that uses a central server to store data that can be used for transactions in a centralized manner, however, this method of using a server to store data in...
