Data alignment method, system, electronic device and readable storage medium

By performing privacy-preserving computations through a matching platform, data participants first send a second string for matching during the data alignment process to obtain the first intersection, and then determine the target first string. This solves the problem of weak privacy in existing technologies and improves the privacy, fairness, and efficiency of data alignment.

AI Technical Summary

Technical Problem

In the process of data alignment, existing technologies have weak privacy protection, especially after the data user sends the hash value to the data provider, the data provider can infer the real data ID, resulting in unfairness and weak privacy.

Method used

Privacy calculations are performed through a matching platform. Each data participant sends a second string to the matching platform for matching to obtain the first intersection. After the data participants determine the target first string, the matching platform performs the second intersection calculation, avoiding direct interaction and ensuring privacy and fairness.

Benefits of technology

It achieves privacy and fairness in the data alignment process, improves data alignment efficiency, reduces the amount of data exchanged, and ensures data security and authenticity.

Abstract

The embodiment of the application provides a data alignment method, system, electronic equipment and readable storage medium, and relates to the technical field of data processing. The embodiment of the application sends at least one second string to a matching platform by each data participant, so that the matching platform matches each second string sent by each data participant, obtains a first intersection, and sends the first intersection to each data participant. After each data participant obtains the first intersection, for each target second string in the first intersection, the data participant determines a target first string corresponding to the target second string, and sends each target first string to the matching platform, so that the matching platform matches each target first string sent by each data participant, obtains a second intersection, and sends the second intersection to each data participant. In this way, the direct interaction of each data participant is avoided through the matching platform, and the privacy of each data participant in the data alignment process is ensured.
