Blockchain-Based Interoperable Electronic Health Record Sharing Framework

Electronic Health Records have proven to be indispensable yet continue to present a host of problems. One of the most pressing concerns is how to share patient information freely and efficiently. Hospitals and clinics may share data internally, but there is an inability due to the lack of infrastructure or an unwillingness to share data between systems. Implementing a peer-to-peer distributed digital ledger, known as a blockchain, to record and transmit transactional data in conjunction with Cloud based technologies may be a solution to bridge the communication gap. This paper sets forth a new approach for a blockchain and cloud computing network utilizing Amazon Web Services and Ethereum blockchain to facilitate semantic level interoperability of Electronic Health Records systems without standardized data forms and formatting.
