Data matching method, device and computer-readable storage medium

Abstract

The disclosure relates to a data matching method, device and computer-readable storage medium, and belongs to the technical field of the Internet. The method includes: generating at least one first prefix data based on at least one first single piece of data in the first data to be matched; generating a first filtering algorithm according to the at least one first prefix data, and converting the first The amount of data, the first filtering algorithm and the first public key are added to the block chain; the second filtering algorithm is obtained in the block chain, and the first data to be matched is filtered based on the second filtering algorithm to obtain intersection data. In this disclosure, the first node generates the first filtering algorithm, and the second node generates the second filtering algorithm, so that the first node can obtain intersection data based on the second filtering algorithm, so that the first node and the second node only need to publicize the generated filtering algorithm The algorithm does not need to disclose the original data to be matched, improves the confidentiality of the determined intersection data, and ensures the equality of each node on the blockchain of the data sharing system.

Description

Technical field [0001] The present disclosure relates to the field of Internet technology, and more particularly to a data matching method, device, and computer readable storage medium. Background technique [0002] With the continuous development of Internet technology, in order to realize multi-party win-win, multiple independeals can form alliances, and share data between data in the alliance, determine the intersection data between multiple separate regions. For both or more parties in the alliance, each independent data is matched, and the intersection data between multiple separate regions can be obtained, which in turn can be targeted for planning. Wait. For example, two or more countries may wish to identify the same suspects in various countries to make more comprehensive monitoring of suspects through sharing information in a certain case. [0003] In the relevant technique, multiple independessors in the alliance are determined to intend to intend to intend to intend t...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problems existing in related technologies, sometimes if all the independent parties in the alliance are unwilling to publicly expose the data to be matched to other independent parties, data matching cannot be achieved, which makes the alliance formed by multiple independent parties unequal. And the problem of low confidentiality, the disclosure provides a data matching method, device and computer-readable storage medium
