Service data processing method, device, electronic device and storage medium

Abstract

The present invention provides a business data processing method, device, electronic equipment, and storage medium. The method includes: acquiring a prime number parameter and a proportional coefficient that match the business data processing system, and determining the first The second parameter of the first key information matched by the service terminal; encrypted transmission of the first service data of the first service terminal, and encrypted transmission of the received second service data of the second service terminal ; Through the encrypted transmission of the first service data and the encrypted transmission of the second service data, determine the intersection of the first service data of the first service terminal and the second service data of the second service terminal as The target service data of the service data processing system can thereby reduce the calculation cost, improve the efficiency of service data processing, realize the processing of service data in the mobile terminal, and save the waiting time of users.

Description

Technical field[0001]The present invention relates to data processing technology in a cloud network, in particular to business data processing methods, devices, electronic equipment and storage media.Background technique[0002]When different business parties share part of the business data, it is necessary to ensure safe multi-party calculation, that is, multiple parties jointly calculate the result of a function without revealing the input data of all parties to the function, and the calculation result is disclosed to one or more parties . For example, a typical application of secure multi-party computing is privacy engagement. PSI Private setintersection (PSI Private setintersection), or collision library, can be understood as determining the intersection between multiple parties on the premise of privacy protection. Privacy request can be applied in business scenarios such as multi-head lending or multi-party information sharing. In this process, one or more parties should get the...

Problems solved by technology

In related technologies, due to the defects of encrypted transmission, users' private data will often be leaked. At the same time, when faced with a large volume of business data to be processed, the calculation of the power modulus operation in the traditional exchange encryption function structure is complicated. The degree of encryption is high, and the hardware overhead of the encryption process is relatively large, which makes the user's waiting time longer and increases the cost of hardware usage, which is not conducive to the realization of business data processing in mobile terminals.
