Secure Computation Data Cleansing for Cross-Organization Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secure computation systems struggle to perform analysis when data from different formats are registered, leading to analysis failures.
Innovation Solution
A processing system that includes a cleansing server to perform data cleansing processing on data from multiple organizations, storing the data in a fragmented share state across multiple servers, and performing analysis processing on secure computation based on the cleansed data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data from multiple organizations with different formats are directly input into the secure computation system, then data accumulation and cross-sectional analysis are enabled, but analysis cannot be performed due to format differences
Solution Approach 1:
The patent applies preliminary action by performing data cleansing processing before the secure computation analysis. The cleansing server standardizes data formats from multiple organizations into a unified format predetermined by the secure computation system, ensuring that all data is properly formatted before analysis execution, thus preventing analysis failures due to format incompatibility
Solution Approach 2:
The patent introduces a cleansing server as an intermediary component between data submission and secure computation analysis. This mediator performs format standardization and data cleansing operations, transforming heterogeneous data from various organizations into a unified format that the secure computation system can reliably process
2Adaptability or versatility
If data cleansing processing is performed on data from multiple organizations, then format compatibility is achieved, but additional processing steps and system complexity are introduced
Solution Approach 1:
The cleansing server is designed with multi-functionality, handling various data format conversions and cleansing operations through a single unified system. This universal approach allows the system to process diverse data formats from multiple organizations without requiring separate processing systems for each format, thus managing complexity while maintaining versatility

AI summary
A processing system (1) is a processing system that stores data in a fragmented share state in a distributed manner across a plurality of devices, and includes a cleansing server (40) that includes a cleansing unit (42) that performs data cleansing processing for secure computation registration on pieces of data transmitted from a plurality of organizations, a secure computation system (50) that stores the pieces of data after the data cleansing processing in a fragmented share state in a distributed manner across a plurality of servers, and performs analysis processing in response to an analysis request on secure computation based on the pieces of data after the data cleansing processing, and a web server (60) that outputs an analysis result of the analysis processing performed in response to the analysis request to a request source of the analysis request.
