Embodiment 1
[0043] This embodiment provides a method for realizing the geographically weighted average center based on secure multi-party computing, please refer to figure 1 , the method includes:
[0044] Step S1: Split the calculation part of the method into a local calculation part and a secure multi-party calculation part, wherein the local calculation part specifically includes: the initiator and the receiver respectively preprocess their respective local data.
[0045]Specifically, Secure Multi-Party Computation (Secure Multi-Party Computation, MPC) is an important research direction in the field of cryptography. , or the method of retaining the process data to calculate the data of the other party), collaboratively calculate a functional function, and finally get the correct result fairly. Currently, many computing frameworks have been designed for secure multi-party computing in academia. This solution is based on a general two-party secure computing architecture implemented by G...
