Embodiment approach

[0089] The first implementation mode of step 104: the terminal determines the number of data information with the same information content among the data information belonging to the same data attribute identifier; the terminal determines the data information with the largest number as the final data information.

[0090] The second implementation manner of step 104: the terminal determines the weight corresponding to each node identifier according to the preset correspondence between node identifiers and weights; the terminal determines the weight corresponding to each node identifier, for each The weight of the data information corresponding to a node identifier; the terminal determines the sum of the weights of the data information with the same information content among the data information belonging to the same data attribute identifier; the terminal determines the data information with the largest sum of weights as the final data information .

[0091] In this embodiment...

Abstract

The present application provides a data acquisition method and system based on block chain, the method comprises the following steps: a terminal sends a data acquisition request to at least one node in a block chain, wherein the data acquisition request includes a user identification and a data attribute identification, so that each node in the at least one node determines data information corresponding to the user identification and the data attribute identification; the terminal receives data information sent by each of the at least one nodes, wherein the data information includes a data attribute identification; the terminal decrypts each data information in at least one data information to obtain each decrypted data information. The terminal determines the final data information according to each decrypted data information. Because the data information is encrypted in pieces and placed on different nodes, the incompleteness of pieces of data can ensure the absolute security of thedata, and the data information will not be sold and disclosed.

Description

technical field [0001] This application relates to data processing technology, in particular to a blockchain-based data acquisition method and system. Background technique [0002] A data management platform (Data Management Platform, DMP for short) system is widely used in the field of data processing, for example, in industries such as advertising placement and e-commerce marketing. Data providers have their own DMP systems, and data can be obtained from the DMP systems of various data providers. [0003] In the prior art, due to competition among data providers, in order to obtain more data in DMP systems, data in multiple DMP systems may be purchased, and then more data in DMP systems may be obtained. [0004] However, in the existing technology, because the data can be copied, the data of each DMP system will be copied and sold, which will cause commercial losses to the data provider; and it will easily cause data leakage, which will lead to user privacy in the data. ...
