ABSTRACT
Health information exchanges have gained dominance for sometime due to their immense relevance. Despite their pressing needs and frequent use, one persistent problem is that data owners are unable to govern data once it has been transmitted. The lack of a technical mechanism to accurately govern patient health data in the network has an impact on health and medical institutions' participation, while also perpetuating a silo-based data management network that locks in the value and potential discovered in data application. Researchers are thus not only able to get these data accurately, but they also generate a lack of data for research and analysis, which is detrimental to the life of patients. We develop a blockchain-supported architectural framework for safeguarding personal data in a health information exchange by combining user-generated acceptable policies with smart contracts. We discuss the advantages of our system, such as its user-centric focus, and provide experimental results as well as future directions for our research. We accomplish this by devising a technique that poses a minimal danger to data.
