The amount of healthcare data is increasing. However, issues with unstandardized data formats and the reliability of provenance make the data challenging to share with other institutions. This paper proposes a standards-based sharing framework, SHAREChain, which incorporates two features to deal with reliability and interoperability issues. First, it improves reliability by using the data integrity of a Blockchain-registry and constitutes a Consortium Blockchain Network to share data solely between authenticated institutions. The second feature improves interoperability with standards relating to healthcare data sharing: Fast Healthcare Interoperability Resources and Cross-Enterprise Document Sharing.
