Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing health data verification systems lack robust methods to ensure data authenticity and privacy, particularly in remote healthcare consultations and insurance claims, where falsification of health data can occur due to potential gains from tampering.
Innovation Solution
A system utilizing user wearable devices and a hub device to encrypt and hash health data asymmetrically, recording cryptographic hash blocks on a distributed ledger, ensuring data integrity and allowing verification by third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If health data is stored at user's home on personal devices, then user privacy and comfort are improved, but data authenticity and verification capability deteriorate
Solution Approach 1:
The system performs preliminary hashing of health data and stores the hash blocks on a distributed ledger before any verification is needed. This preliminary action creates a trusted reference point that enables future verification without complex real-time validation systems, resolving the contradiction by preparing verification capability in advance.
Solution Approach 2:
The patent introduces cryptographic hash blocks as an intermediary between the stored health data and verification processes. These hash blocks serve as mediators that enable third-party verification without requiring direct access to or complex validation of the actual health data, thus maintaining simplicity while ensuring authenticity.
2Reliability
If health data is stored on a server, then data verification capability is improved, but user privacy and data security deteriorate
Solution Approach 1:
The patent extracts only the essential verification element (cryptographic hash block) from the complete health data and stores it on the distributed ledger. The actual health data remains privately stored at user's home, while the extracted hash enables verification capability without exposing sensitive information, thus resolving the contradiction between verification and privacy.
Solution Approach 2:
Instead of storing or transmitting actual health data for verification purposes, the system creates and stores a cryptographic copy (hash block) that preserves verification capability while maintaining privacy. This copying approach allows third parties to verify data integrity without accessing sensitive health information.
3Device complexity
If data verification is not implemented, then system complexity is reduced, but data authenticity and trustworthiness deteriorate
Solution Approach 1:
The verification system is designed to be self-service through the inherent properties of cryptographic hashing and distributed ledger technology. The hash blocks automatically verify data integrity through mathematical properties rather than requiring complex active validation mechanisms, enabling trustworthiness with minimal system complexity.
Solution Approach 2:
The patent replaces complex mechanical verification systems with cryptographic mechanisms. Instead of using intricate validation protocols or trusted intermediary systems, the solution uses mathematical hash functions and distributed ledger consensus mechanisms that provide automatic verification with simpler overall system architecture.
