Privacy Preservation; Blockchain Security; Increasing Efficiency.

The handling and accessibility of Electronic Medical Records (EMRs) have been completely transformed by the growing integration of cloud computing and Internet of Things (IoT) technologies in the healthcare industry. This research presents a new method for implementing a lightweight blockchain-based access control system to meet the critical security and efficiency concerns in the sharing of fog- assisted IoT cloud-based EMRs. Thanks to the integration of data from several medical treatment applications and Internet of Things devices, the outsourcing of encrypted electronic medical records (EMRs) has become a fundamental aspect of the modern healthcare scene. This strategy has unmatched benefits, such as increased accessibility, efficient inter-professional collaboration, and a significant decrease in computational operation expenses. The goal of this research project is to maximise the effectiveness of EMR sharing while simultaneously strengthening the security of sensitive medical data. The suggested framework makes use of blockchain technology to provide a simple and safe access control system 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.
