A Blockchain-Based Secret-Data Sharing Framework for Personal Health Records in Emergency Condition

Area of Science:

• Computer Science
• Information Security
• Healthcare Informatics

Background:

• Blockchain offers immutable and irreversible transaction security.
• Personal Health Record (PHR) systems require robust data management and privacy controls.
• Current PHR systems face challenges in emergency access and data tampering.

Purpose of the Study:

• To propose a blockchain-based healthcare management framework.
• To enhance security, privacy, and emergency access for personal health records.
• To ensure tamper-proof data and efficient auditing capabilities.

Main Methods:

• Implementation of a decentralized blockchain network for healthcare data.
• Integration of extensible access control and auditing policies.
• Development of tamper-resistant mechanisms for emergency scenarios.

Main Results:

• The proposed framework demonstrated superior performance in accessibility and privacy.
• Enhanced emergency access control was achieved without compromising data integrity.
• Effective data auditing and tamper resistance were validated through experiments.

Conclusions:

• Blockchain technology provides a secure and reliable solution for healthcare data management.
• The proposed framework effectively addresses limitations in current PHR systems.
• This approach offers significant improvements in patient data security, privacy, and emergency accessibility.
