Technology against COVID-19 A Blockchain-based framework for Data Quality

The effects of COVID-19 have quickly spread around the world, testing the limits of the population and the public health sector. High demand on medical services are offset by disruptions in daily operations as hospitals struggle to function in the face of overcapacity, understaffing and information gaps. Faced with these problems, new technologies are being deployed to fight this pandemic and help medical staff governments to reduce its spread. Among these technologies, we find blockchains and Big Data which have been used in tracking, prediction applications and others. However, despite the help that these new technologies have provided, they remain limited if the data with which they are fed are not of good quality. In this paper, we highlight some benefits of using BIG Data and Blockchain to deal with this pandemic and some data quality issues that still present challenges to decision making. Finally we present a general Blockchain-based framework for data governance that aims to ensure a high level of data trust, security, and privacy.
