Multi-party computation of split private data with address geo-coded component

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations, comprising:
• obtaining, by each secure multi-party computation (MPC) computation party of a system comprising a data provider and n secure MPC computation parties, a first data component from a data message sent by the data provider, wherein n is an integer greater than 3, wherein the first data component is one of a plurality of data components obtained after the data provider splits private data, and wherein the first data component is an address-geocoded component;
• and
• performing, as MPC processing and to obtain a second data component, conversion of the first data component from the address-geocoded component and to a one-hot encoded component, wherein the conversion comprises obtaining a value of each bit of the one-hot encoded component based on a combination product of a value or a complement value of each bit of an address-geocoded component corresponding to each bit of the one-hot encoded component.
