An IoMT data security framework with Hyperledger Fabric for smart cities

There is a high-risk privacy issue related to the Internet of Medical Things (IoMT) because of a lack of security in critical and sensitive information. We propose a framework for securing medical data in Healthcare 5.0 generated by the IoMT. Our framework uses Hyperledger Fabric (HF), a permissioned blockchain platform, to provide a decentralized and tamper-proof system for data management and sharing. The proposed framework includes modules for identity management, data encryption, and access control for Healthcare 5.0. Hyperledger is a Linux Foundation-hosted open-source project. The HF is one of the IBM-developed initiatives that eventually contributed to Hyperledger. The paper presents the architecture of the framework, as well as a prototype implementation and evaluation of its performance and security specific to consumer electronics for Smart Cities. This evaluation demonstrated that the proposed framework is efficient and effective at securing medical data in the IoMT, and could be used to develop secure and scalable healthcare systems in the future.
