Blockchain Consent Management for Cross-Facility Personal Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data processing consent management systems in healthcare facilities face high production and collection costs, inconsistency, fragmentation, and localization issues, leading to difficulties in verifying and exchanging consent across different facilities.
Innovation Solution
A scalable system utilizing a blockchain-based architecture with supervisor and company nodes to manage consent and access to personal data, ensuring consistency and controlled access across a network of interconnected electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If consent management is entrusted to individual healthcare facilities, then local application of consent is enabled, but production and collection costs increase significantly and consistency between documents deteriorates
Solution Approach 1:
The patent merges consent management functions from multiple individual healthcare facilities into a single centralized system. The centralized body collects and manages consent documents uniformly across all facilities, eliminating the need for each facility to independently produce and manage its own consent documentation, thereby reducing overall costs and improving consistency.
Solution Approach 2:
The centralized body acts as an intermediary between users and multiple healthcare facilities. It receives consent from users once and then distributes or shares this consent information with various facilities as needed, eliminating the need for each facility to separately collect and manage consent documents.
2Adaptability or versatility
If consent management is decentralized to individual facilities, then facility autonomy is maintained, but fragmentation of consent data occurs and interchange with other facilities becomes difficult
Solution Approach 1:
The system merges fragmented consent information from multiple facilities into a single centralized repository. The centralized body maintains a unified view of consent data across all facilities, preventing fragmentation and enabling comprehensive data interchange while preserving the autonomy of individual facilities to access and use the consent information as needed.
3Reliability
If a centralized body manages consent, then consistency and global view are achieved, but system complexity increases
Solution Approach 1:
The centralized body is designed as a multi-functional system that handles various tasks including consent collection, data storage, access control, and distribution to different facilities. By consolidating these multiple functions into a single system, the patent achieves consistency and reliability while managing complexity through integrated design rather than separate systems.

AI summary
The invention is a method for managing the processing of a user's personal details in a computer system comprising a network of interconnected electronic devices. Said computer system comprises at least one supervisor node (NS), one or more company nodes (A) connected to said at least one supervisor node (NS), and wherein each of said nodes in turn comprises at least one electronic device, a blockchain (B), that is, a set of information, and wherein said blockchain (B) is identically replicated in each one of said nodes (NS, A), and one or more communication channels (D, T1, T2,...).
