Enabling trust in healthcare data exchange with a federated blockchain-based architecture

Abstract

We propose a new healthcare data exchange platform for research centers, hospitals and healthcare institutions. Our model is based on a federated blockchain network that interconnect the healthcare institutions and orchestrate the data life cycle from the data publication to the data consumption. The blockchain is responsabible to keep the traceability of the whole process and we use a specially designed smart contract to control the data sharing process. Moreover, we provide the means to enforce GDPR and thus achieve a GDPR compliant model.
