Problems solved by technology

[0008] However, due to reliance on intermediate table mapping, and / or centralized processing in the mapping and / or matching process, both the to-be-matched table details and the intermediate table details are at risk of data leakage
Even if the identity column after the hash (Hash) is used for matching, there are potential risks such as "rainbow table attack"

Embodiment Construction

[0038] In order to better understand the technical solutions of the present invention, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0039] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than listing all the embodiments. Based on the embodiments described in the present disclosure, all other variations obtained by persons of ordinary skill in the art without making customary labors belong to the protection scope of the present application.

[0040] figure 2 A Secure Multi-Party Computing (SMC / SMPC) scenario 200 is shown according to an exemplary embodiment of the present disclosure. As can be seen, multiple SMPC nodes are included in the scene, including matching data party A, matching data party B and other SMPC members C1 - C10. As known to those skilled in the art, the scenario 200 is just an example of an SMPC scenario, a...

Abstract

One aspect of the present disclosure relates to a method of data security matching, comprising receiving a request for optimal security routing for security matching of at least two datasets with heterogeneous identifiers; determining an optimal secure route capable of performing mapping between the heterogeneous identifiers in a secure multi-party computing environment; and providing the determined optimal secure route for secure matching of the at least two datasets by a secure intersection based on the optimal secure route. The invention further relates to corresponding equipment, a corresponding device and a corresponding computer readable medium. Other aspects of the present disclosure relate to other corresponding methods, apparatuses, and systems.

Description

technical field [0001] The present application relates to secure multi-party computation (SMC / SMPC), and in particular to a method and device for secure matching of heterogeneous identification data. Background technique [0002] In recent years, data has shown a trend of rapid growth. Especially in the context of big data, there is an urgent need to enable a large number of mutually distrusting parties to conduct safe, effective and efficient multi-party cooperation without disclosing their respective information. [0003] Secure intersection (PSI) is a technique for a subproblem in secure multiparty computation. This technology calculates the data intersection of each participant on the premise of protecting the details of each participant's respective data sets from being leaked. PSI has great value and prospects in social, military, commercial, financial, government and other fields. [0004] In the simplest scenario, a PSI may involve two parties, say sender A and re...
