The rapid growth of the Internet of Medical Things (IoMT) is transforming modern healthcare by enabling continuous patient monitoring, early disease detection, and improved clinical decision-making. However, healthcare data is often distributed across multiple hospitals, medical institutions, and digital platforms, creating significant challenges related to interoperability, secure data sharing, privacy, and efficient data management. To address these issues, this project proposes a blockchain-enabled framework for the secure, interoperable, and privacy-preserving validation and storage of IoMT-generated healthcare data. The proposed system utilizes Hyperledger Fabric, a permissioned blockchain platform, to provide controlled access, tamper-resistant data management, secure transactions, and transparent auditing within healthcare environments. Edge computing is also incorporated to process data closer to IoMT devices, thereby reducing communication latency, minimizing network congestion, and improving the efficiency of real-time healthcare services. The decentralized architecture enables authorized healthcare stakeholders to securely exchange patient information while maintaining data integrity, confidentiality, and privacy. The framework can support important applications such as remote patient monitoring, preventive healthcare, and timely clinical intervention. Experimental evaluation indicates that the proposed approach has the potential to enhance healthcare workflow efficiency, accelerate clinical decision-making, and support a more patient-centered model of healthcare data management. Overall, the proposed framework contributes toward the development of a secure, scalable, interoperable, and efficient digital healthcare infrastructure for future IoMT-based healthcare systems.
