Ensuring Access Control Reliability and Security of Lightweight Blockchain-Based IOT Cloud-Based Electronic Medical Records Sharing

EMRs, or electronic medical records, and their accessibility have undergone a significant transformation as a result of the healthcare industry’s growing adoption of cloud computing & Internet of Things, or IoT, technology. In order to address the crucial safety and effectiveness concerns in sharing of fog-assisted Internet of Things based on the cloud EMRs, this research proposes a novel approach for constructing a lightweight control system for access based on blockchain. The outsourcing of secured electronic medical records, or EMRs, has come to be a vital component of the contemporary healthcare landscape, mostly due to the collection of data from several healthcare application and Internet of Thing devices. This strategy has unmatched benefits, such as increased accessibility, efficient interprofessional collaboration, and a significant decrease in computational operation expenses. The goal of this research project is to maximize the effectiveness of EMR sharing while simultaneously strengthening the security of sensitive medical data. The suggested framework leverages blockchain technology to provide an intuitive and safe access control mechanism for the Internet of Things, with assistance from Fog. By doing this, the system delivers strong resistance to unwanted access, transparent access, and data integrity. Privacy Preservation using cutting-edge encryption methods to safeguard medical data privacy.Blockchain Protection implementing access control on blockchain to raise the general security of the system. Increasing Efficiency Making use of Fog-assisted IoT to reduce computing expenses and optimize data-sharing procedures.
