Privacy-protected set confusion intersection method and system and related equipment

Abstract

The embodiment of the invention discloses a set confusion intersection method and system for privacy protection and related equipment, the system comprises an initiator and a result party, and the method comprises the following steps: adding a label field to a first data set through the initiator to obtain a reference first data set; adding a label field to the second data set through a result party to obtain a reference second data set; the method comprises the following steps: performing data splicing operation on a reference first data set through an initiator to obtain A pieces of reference first data; performing data splicing operation on the reference second data set through a result party to obtain B pieces of reference second data; performing intersection operation on the A pieces of reference first data and the B pieces of reference second data through the initiator to obtain an intersection result, and determining target label information according to the intersection result; and the result party screens the first data set according to the target label information to obtain a target intersection result. By adopting the embodiment of the invention, the purpose of privacy protection can be realized in the confusion intersection process.

Description

technical field [0001] The present application relates to the field of privacy computing technology and the field of computer technology, and in particular to a privacy-preserving set confusion intersection method, system, and related equipment. Background technique [0002] With the development of artificial intelligence, the value of data has been paid more and more attention. Data analysis has also become the focus of research. Set obfuscation intersection is a set intersection scheme with special functions. Each piece of data from the result party and the initiator has multiple information fields. As long as one of the fields matches with each other, it can be regarded as a successful intersection of the entire piece of data. However, the traditional set obfuscation and intersection scheme will expose the field information that matches successfully on the result side. Therefore, the problem of how to achieve the purpose of privacy protection in the process of obfuscatio...
