- 🌐 Accessibility: Global sharing of medical information
🔑 Key Takeaways
- 🌍 Global Reach: The system allows for medical information sharing across borders.
- 🔑 Biometric Authentication: Ensures that only authorized personnel can access sensitive medical data.
- 💡 Practical Implementation: The blockchain’s fee structure has been tested, confirming feasibility.
- 🚑 Emergency Preparedness: Facilitates immediate access to critical health records in emergencies.
- 👨⚕️ Family Doctor Involvement: Enables family doctors to share health records securely with emergency responders.
- 🛡️ Security Assurance: The pendant’s features prevent unauthorized access even if stolen.
- 📈 Future Potential: This system could revolutionize emergency medical care by improving information accessibility.
📚 Background
The transition from paper-based to electronic medical records has been a significant advancement in healthcare. However, sharing these records during emergencies remains a challenge, particularly when patients are incapacitated. Traditional systems often rely on permissioned blockchains, which limit access to pre-designated participants, making it difficult to share vital information with local emergency doctors when needed most.
🗒️ Study
The authors of this study propose a novel solution: an emergency access control system that leverages a public blockchain. This system is designed to be inclusive, allowing anyone to participate in the sharing of medical information. The key innovation is a pendant worn by the patient, equipped with biometric authentication capabilities, which can be used by emergency doctors to access the patient’s medical records securely.
📈 Results
The study demonstrates that the proposed system is not only innovative but also practical. The testing of the blockchain’s fee structure indicates that the system can be implemented without prohibitive costs, making it a viable option for healthcare providers. The use of the Diffie-Hellman key exchange protocol ensures that the sharing of information is secure and reliable.
🌍 Impact and Implications
This breakthrough in emergency medical access could significantly enhance patient care during critical situations. By enabling immediate access to medical records, healthcare providers can make informed decisions quickly, potentially saving lives. The implications extend beyond individual cases, as this system could lead to a more interconnected and responsive healthcare ecosystem globally.
🔮 Conclusion
The proposed emergency medical access control system represents a significant step forward in the integration of blockchain technology into healthcare. By addressing the challenges of information sharing in emergencies, this system has the potential to improve patient outcomes and streamline emergency medical responses. Continued research and development in this area could pave the way for broader applications of blockchain in healthcare.

Emergency Medical Access Control System Based on Public Blockchain.
Abstract
IT has made significant progress in various fields over the past few years, with many industries transitioning from paper-based to electronic media. However, sharing electronic medical records remains a long-term challenge, particularly when patients are in emergency situations, making it difficult to access and control their medical information. Previous studies have proposed permissioned blockchains with limited participants or mechanisms that allow emergency medical information sharing to pre-designated participants. However, permissioned blockchains require prior participation by medical institutions, and limiting sharing entities restricts the number of potential partners. This means that sharing medical information with local emergency doctors becomes impossible if a patient is unconscious and far away from home, such as when traveling abroad. To tackle this challenge, we propose an emergency access control system for a global electronic medical information system that can be shared using a public blockchain, allowing anyone to participate. Our proposed system assumes that the patient wears a pendant with tamper-proof and biometric authentication capabilities. In the event of unconsciousness, emergency doctors can perform biometrics on behalf of the patient, allowing the family doctor to share health records with the emergency doctor through a secure channel that uses the Diffie-Hellman (DH) key exchange protocol. The pendant’s biometric authentication function prevents unauthorized use if it is stolen, and we have tested the blockchain’s fee for using the public blockchain, demonstrating that the proposed system is practical.
