Blockchain-enabled secure and efficient data sharing scheme for trust management in healthcare smartphone network

Area of Science:

• Computer Science
• Cybersecurity
• Health Informatics

Background:

• The Internet of Medical Things (IoMT) enables remote patient monitoring but faces security risks from compromised devices.
• Healthcare Smartphone Networks (HSN) are vulnerable to data breaches via malicious IoMT nodes.
• Secure and trusted exchange of confidential patient records is crucial for remote healthcare.

Purpose of the Study:

• To propose a novel technique for identifying compromised IoMT nodes within HSNs.
• To enhance the security and privacy of sensitive patient health records.
• To improve the overall reliability and resilience of IoMT-based healthcare systems.

Main Methods:

• Implementation of a Hyperledger blockchain framework to detect malicious IoMT nodes.
• Development of a Clustered Hierarchical Trust Management System (CHTMS) for node blocking.
• Integration of Elliptic Curve Cryptography (ECC) for data protection and Denial-of-Service (DoS) resilience.

Main Results:

• The proposed blockchain-based system significantly improved the detection performance of compromised IoMT nodes.
• Evaluation demonstrated enhanced security and reliability compared to existing methods.
• The system effectively safeguards sensitive health records against unauthorized access.

Conclusions:

• Integrating blockchain technology into HSNs offers a robust solution for IoMT security.
• The CHTMS and ECC provide effective mechanisms for threat mitigation and data protection.
• The proposed approach enhances the trustworthiness of remote patient health monitoring systems.
