Blockchain EHR Platform with Micro-Identifier Chains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems face challenges in scalability, security, and compliance with international data privacy laws, particularly due to their inability to efficiently handle electronic health records (EHRs), which are often stored on incompatible systems, leading to inefficiencies and legal violations.
Innovation Solution
A transaction platform utilizing a notary distributed ledger or blockchain combined with micro-identifier chains (MIDCs) enables secure, compliant storage and sharing of EHRs by allowing for the creation, updating, and deletion of data while maintaining transaction party confidentiality and preventing chain poisoning, using a partitioned RAFT replication protocol and non-fungible tokens (NFTs) for secure data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional EHR systems are used with multiple providers, then each provider can maintain their own records, but data interoperability is poor and doctors cannot easily share patient data
Solution Approach 1:
The patent implements a universal blockchain-based EHR system where a single standardized data structure can be accessed and shared across multiple healthcare providers. The common data model with standardized fields (patient demographics, clinical observations, lab results, etc.) allows any authorized provider to read and write EHR data without needing to integrate with proprietary systems, achieving multi-functionality across diverse healthcare organizations.
Solution Approach 2:
The blockchain network acts as an intermediary layer between different healthcare providers' EHR systems. Rather than directly integrating disparate systems, providers interact with the blockchain through standardized interfaces, and the blockchain mediates data sharing by providing a trusted, shared ledger that all parties can access according to their permissions.
2Reliability
If EHR data is shared across multiple providers, then patient care can be improved, but data security and privacy compliance become more difficult to maintain
Solution Approach 1:
The patent implements preliminary action by establishing cryptographic identity verification and access control permissions before any EHR data is shared. The system pre-configures which providers can access which patient data based on authorized relationships, and these permissions are enforced automatically by the blockchain smart contracts before data access occurs, preventing unauthorized sharing while enabling legitimate care coordination.
Solution Approach 2:
The blockchain system provides continuous feedback through its immutable ledger, recording all data access transactions with timestamps and authorization verification. This creates an audit trail that allows real-time monitoring of data sharing activities, enabling security personnel to detect and respond to potential breaches while maintaining compliance with privacy regulations through transparent, verifiable access control.
3Reliability
If blockchain systems store EHR data, then data integrity and security are improved, but transaction throughput and scalability are limited
Solution Approach 1:
The patent applies segmentation by dividing EHR data into discrete, standardized record types (patient demographics, clinical observations, lab results, medications, etc.) that can be independently stored and managed as separate blockchain transactions. This modular approach allows the system to process and store different data elements efficiently, with each segment being self-contained and verifiable, improving overall transaction throughput while maintaining data integrity.
