Data matching method, device and computer-readable storage medium

Abstract

The invention relates to a data matching method and device and a computer readable storage medium, and belongs to the technical field of the Internet. The method comprises the following steps that: on the basis of an encryption character string, encrypting first data to be matched, and generating first encryption data; according to the first encryption data, generating a first filtering algorithm, and adding the first filtering algorithm into a blockchain in a data sharing system; obtaining a second filtering algorithm in the blockchain, carrying out filtering on the first encryption data on the basis of the second filtering algorithm to obtain first data; and if the first data is consistent with second data, taking the first data as intersection data that a first node and a second node are matched. The first node and the second node carry out encryption on data to be matched on the basis of an encryption character string to generate first encryption data and second encryption data, only the encryption data needs to be disclosed to determine the intersection data without disclosing the data to be matched, the confidentiality of the data to be matched is improved, and the equality of each node of the data sharing system is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of the Internet, in particular to a data matching method, device and computer-readable storage medium. Background technique [0002] With the continuous development of Internet technology, in order to achieve a win-win situation for multiple parties, multiple independent parties can form an alliance and share data in the alliance to determine the intersection data between multiple independent parties. For two or more parties that share data in the alliance, matching the data of each independent party can obtain the intersection data among multiple independent parties, and then based on the intersection data, targeted plan planning can be carried out Wait. For example, two or more countries may wish to share information on suspects in a case to identify the same suspects that each country is monitoring for more comprehensive surveillance of suspects. [0003] In related technologies, when multiple ...

Problems solved by technology

[0005] When performing data matching, one of the multiple independent parties needs to share all the data to be matched with other independent parties in the alliance, resulting in an independent party needing to publicly expose all the data to be matched, making 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 low in confidentiality
