Title:
PROCESSING SYSTEM, PROCESSING METHOD, AND PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/203062
Kind Code:
A1
Abstract:
A processing system (100) in which original data is stored on a plurality of servers in a distributed manner as shares obtained by fragmenting the original data, wherein the plurality of servers (20A) to (20C) each include a statistical processing unit that statistically processes shares used in computation requested by a requesting terminal device (30) and a computational processing unit that uses statistical information converted in the statistical processing to perform the computation requested by the requesting terminal device (30).
