LEVERAGING BLOCKCHAIN FOR SECURING AND MANAGING MEDICAL IOT DATA
Velivela Gopinath, K. Venkata Rao, S. Krishna Rao · 2023
The rapid proliferation of Internet of Things (IoT) devices in the healthcare sector has ushered in transformative possibilities for patient care and medical data management. However, the integration of IoT devices also introduces significant challenges related to data security, privacy, and trust. In this paper, we propose a novel framework that leverages blockchain technology to enhance the security and management of medical IoT data. Our framework capitalizes on the inherent properties of blockchain, including decentralization, immutability, and cryptographic security, to establish a robust foundation for medical data storage and sharing. By utilizing smart contracts and cryptographic mechanisms, we enable fine-grained access control, ensuring that only authorized entities can interact with sensitive medical data. This not only enhances data security but also fosters patient trust in the IoT ecosystem. Moreover, we address the issue of data integrity by employing blockchain's tamper-resistant nature. Every data transaction is recorded on the blockchain, creating an immutable audit trail that ensures transparency and accountability. This feature proves crucial for compliance with regulatory standards and for detecting unauthorized data alterations. Through a comprehensive evaluation, we demonstrate the efficacy of our proposed framework in comparison to traditional approaches. We assess its performance, security, and scalability to showcase its viability for real-world deployment. The results underscore the potential of blockchain to revolutionize medical IoT data management by mitigating security risks, improving data access controls, and ensuring data integrity. As a contribution to the intersection of blockchain and healthcare technology, our work offers a foundation for a more secure and transparent healthcare ecosystem. By securing medical IoT data and streamlining its management, our framework holds the promise to drive innovation and improve patient outcomes in the increasingly interconnected world of healthcare.
