Platform-Mediated Communication for Privacy-Preserving Joint Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing big data trading centers fail to meet the data demands of users regarding privacy requirements, deal-making transactions, and ensuring legality and compliance of data packages, as well as failing to select appropriate data providers for joint calculations.
Innovation Solution
A method and apparatus for communication that allows a data demander to send calculation requirements to a platform, which matches them with suitable data providers, ensuring privacy protection and data legality while enabling joint calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a big data trading center is used for data storage and calculation, then data circulation and sharing can be implemented, but it cannot meet the privacy requirements and specific calculation needs of data demanders
Solution Approach 1:
The patent introduces a platform as an intermediary between data demanders and data providers. This platform receives calculation requests from demanders, matches them with appropriate data providers, and coordinates the joint calculation process without requiring direct data sharing between parties. The intermediary structure enables data circulation while protecting privacy by controlling information flow through a trusted third party.
2Productivity
If data is shared through a big data trading center, then data availability improves, but the ability to perform targeted joint calculations with appropriate data providers is lost
Solution Approach 1:
The patent implements preliminary action by having data providers pre-register their data resources, capabilities, and calculation requirements with the platform before actual calculation requests are made. The platform stores this information and uses it to quickly match incoming calculation requests with suitable providers. This pre-positioning of information enables both high data availability and precise matching for joint calculations.
3Ease of operation
If traditional data trading methods are used, then data sharing is achieved, but privacy protection and data security cannot be ensured
Solution Approach 1:
The patent extracts the sensitive data elements from the data sharing process and keeps them localized at the data provider's end. Only non-sensitive calculation results and necessary coordination information are transmitted through the platform. This extraction of sensitive information from the transmission path eliminates privacy leakage risks while maintaining the functionality of data sharing and joint calculation.
