SENSIBLE: SEquestered aNd SynergIstic BLockchain Ecosystem

Abstract

Health care interoperability unfolds the way for personalized health care services at a reduced cost. Furthermore, a decentralized system holds the promise to prevent compromises such as cyber-attacks due to data breaches. Hence, there is a need for a framework that seamlessly integrates and shares data across the system stakeholders. We propose SEquestered aNd SynergIstic BLockchain Ecosystem (SENSIBLE), a blockchain-powered, knowledge-driven data-sharing framework that gives patients complete control of their medical history and can extract rich information hidden in it using knowledge graphs (KGs). By incorporating both blockchain and KGs, we can provide a platform for secure data sharing among stakeholders by maintaining data privacy and integrity through data authentication and robust data integration. We present a Proof-of-Concept of the SENSIBLE network with Ethereum to share dynamic knowledge across stakeholders. Dynamic knowledge generation on the blockchain provides a two-fold advantage of cooperation and communication amongst the stakeholders in the health care ecosystem. This leads to operational ease through sharing relevant portions of complex information while also ensuring the isolation of sensitive medical data.

The Hyperledger fabric as a Blockchain framework preserves the security of electronic health records

“… Knowledge graphs can be dynamically created but cannot be stored on chains. It prevents the data from being tampered with ( 80 ). However, the use of the PoW algorithm on Ethereum makes the system vulnerable when all nodes simultaneously stop working.…”

“…However, the use of the PoW algorithm on Ethereum makes the system vulnerable when all nodes simultaneously stop working. This problem can be addressed by shifting toward the HF framework and using the Byzantine protocol as a consensus algorithm ( 80 , 81 ). Moreover, knowledge graph data, a popular data type, may be used to support authenticated queries, which can be easily manipulated on the blockchain.…”
