HEALTHSOLID 4.0: A NOVEL SOLID-POD AND BLOCKCHAIN-ENABLED FRAMEWORK FOR ROLE- BASED ACCESS CONTROL AND SECURE HEALTHCARE INFORMATION EXCHANGE

Several blockchain-based models have surfaced in recent years to offer a safe method of storing and accessing delicate electronic medical records (EMRs) and role-based access control mechanisms across the healthcare industry. However, single points of failure, Security, privacy and unauthorized access of data are measure concerns for health records access management. Blockchain technology is a decentralized digital ledger that records transactions across multiple computers to ensure security, transparency, and immutability. Solid is a decentralized platform that provides patient centric access control of Electronic Medical Records (EMRs). In this study, a blockchain and solid-pod enabled secure framework has been proposed for EMR transactions and healthcare clouds. This has a significant impact on how quickly and easily emergency EMRs may be shared in a smart healthcare system. Solid and Blockchain prioritize privacy and security by enabling users to set immutable, transparent, and fine-grained access controls for their data using solidity-based smart contracts. For the performance evaluation of our proposed system, solid-pod computing and storage results are analyzed.
