Data Distribution Intermediary for Privacy-Compliant Personal Data Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data distribution intermediary systems struggle to manage the difference in data content between providers and service providers, particularly in ensuring data usage aligns with user consent and privacy protection requirements, especially in dynamic scenarios such as emergencies.
Innovation Solution
A data distribution intermediary system that includes a device with functional units for managing data providers, service providers, personal data conversion, terms-of-service management, consent procedures, and data distribution control, which determines the necessity of data conversion based on metadata differences and performs appropriate conversions to ensure compliant data usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data conversion is performed to align data content between providers and service providers, then data usability and service quality are improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent introduces a data distribution intermediary system that acts as a mediator between data providers and service providers. The intermediary manages data conversion by comparing metadata from both parties, determining necessary conversions, and executing them centrally. This approach improves data usability while containing system complexity within the intermediary component rather than distributing it across all participants.
Solution Approach 2:
The system performs preliminary actions by pre-comparing metadata from data providers and service providers to determine conversion requirements before actual data distribution occurs. The intermediary stores conversion rules and metadata in advance, allowing it to efficiently execute conversions when data is requested, rather than determining conversions in real-time during data transfer.
2Productivity
If data distribution is enabled to promote usage, then data utility and service provision are improved, but privacy protection and security control are worsened
Solution Approach 1:
The patent implements feedback mechanisms where the data distribution intermediary continuously monitors data distribution activities, user consent status, and service provider compliance. The system compares metadata to verify that distributed data matches approved conversion rules and usage terms, providing feedback control that maintains privacy protection while enabling data usage.
Solution Approach 2:
The system dynamically adjusts data distribution based on changing conditions such as user consent updates, service provider credentials, and data usage terms. The intermediary can modify conversion rules and distribution parameters in real-time, allowing data usage to be promoted while maintaining adaptive privacy protection that responds to changing requirements.

AI summary
An object of the invention is to enable usage of data based on terms concluded with a user, and achieves both promotion of usage of personal data and privacy protection related to the personal data. A data distribution intermediary device acquires personal data metadata and generates service usage data metadata based on terms of service related to distribution and usage of the personal data. Then, the data distribution intermediary device detects a difference between the personal data metadata and the service usage data metadata, determines a necessity of conversion processing of the personal data based on the difference between the metadata, and converts the personal data to corresponding service usage data based on the service usage data metadata when the personal data is determined to be necessary to be converted.
