EFFICIENT AND SECURE BLOCKCHAIN-BASED ACCESS CONTROL FOR FOG-ASSISTED IOT CLOUD IN ELECTRONIC MEDICAL RECORDS SHARING

As IoT devices proliferate and healthcare organizations need more efficient ways to share patient data, fogassisted IoT cloud environments have arisen. In such setups, it becomes critical to handle access control tosensitive data effectively and securely, including Electronic Medical Records (EMRs). We tackle this challengecreatively using the Efficient and Secure Blockchain-Based Access Control (ESBAC) framework
