Healthcare Data NFTs With Blockchain Access Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for protecting patient medical records lack necessary security and often fail to provide timely access to critical healthcare data, especially in emergencies or when patient data is unavailable.
Innovation Solution
A system that converts patient healthcare data into non-fungible tokens (NFTs) and manages access using blockchain technology, ensuring secure storage and authentication based on geolocation, biometrics, or tokens, allowing real-time access to healthcare data through digital filing cabinets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods are used to store and protect patient medical records, then data storage is simple and accessible, but data security is insufficient and access control is weak
Solution Approach 1:
The patent introduces blockchain technology as an intermediary layer between healthcare data and access requests. The blockchain ledger acts as a trusted mediator that records all access transactions immutably, providing security without requiring complex centralized authentication systems. Smart contracts serve as automated intermediaries that enforce access policies based on predefined rules, reducing the need for manual security management.
Solution Approach 2:
The patent creates cryptographic copies of access permissions and data ownership rights on the blockchain. Instead of storing sensitive medical records directly on the blockchain, the system stores hashed versions and cryptographic proofs, allowing verification of data integrity and access authority without exposing actual medical data, thus enhancing security while maintaining system simplicity.
2Speed
If patient medical records are stored in conventional systems, then access is relatively easy, but timely access in emergencies is not guaranteed
Solution Approach 1:
The patent implements preliminary action by pre-configuring smart contracts with access policies and permissions before emergencies occur. Access rules, authorized personnel, and data sharing protocols are established in advance and automatically executed when access requests are made, eliminating delays associated with manual authorization during critical situations.
Solution Approach 2:
The system provides real-time feedback through the blockchain ledger, which records all access transactions immutably. This creates a transparent audit trail that provides immediate feedback on who accessed what data and when, enhancing access reliability by ensuring that all accesses are logged and verifiable while maintaining fast access speeds through automated smart contract execution.
3Adaptability or versatility
If patient data is made accessible to multiple providers, then care coordination improves, but data privacy and security risks increase
Solution Approach 1:
The patent applies local quality by allowing different levels of data access for different providers based on their specific needs and roles. Smart contracts can grant granular permissions where each healthcare provider receives only the specific data elements necessary for their treatment responsibilities, rather than providing universal access to all patient records, thus maintaining privacy while enabling necessary data sharing.
Solution Approach 2:
The blockchain smart contracts serve as automated intermediaries that mediate data sharing between patients and multiple providers. These smart contracts enforce privacy policies automatically, ensuring that data is shared only with authorized providers under defined conditions, thereby reducing privacy risks while maintaining versatile data sharing capabilities across the healthcare ecosystem.
4Reliability
If traditional authentication methods are used, then system access is simple, but security against unauthorized access is insufficient
Solution Approach 1:
The patent implements self-service authentication through smart contracts that automatically verify user identities and enforce access policies without requiring manual intervention from administrators. The blockchain system autonomously manages authentication credentials and access permissions, providing strong security through cryptographic verification while maintaining ease of operation through automated, seamless authentication processes for authorized users.
