Blockchain Technology for Healthcare Data

Nowadays, both medical institutions and individuals generate a large amount of data on health diagnostic. These data are critical and sensitive, so to share securely and storing is hard, conventional healthcare systems are facing multiple challenges including data breaching, medical record tampering, frauds, etc. In this paper, our aim is to extend the functionality of a Blockchain-based platform for healthcare information exchange to securely share data, maintaining privacy, and availability. Because, healthcare data contain a large amount of data, which is not feasible to store on Blockchain likes Ethereum chain, due to heavy cost. Moreover, a centralized database is prone to attack and failure leads to loss of data. Therefore, we propose a model of blockchain to use IPFS (InterPlanetry File System) for secure storation, sharing of data, and availability.
