A Secure Blockchain-Based Solution for Management of Pandemic Data in Healthcare Systems

This article tackles the issue of data manipulation in pandemics wherein often the data is manipulated or underreported for various reasons by certain government and public institutions. This problem came to light during the first few months of the COVID-19 pandemic and had a major effect on the public health response in countries around the globe. To solve this issue, a blockchain-based system and implementation is proposed to allow hospitals and testing centres to transmit their data while also minimising the risk of manipulation from government bodies. The article makes use of the United States CDC framework for data reporting by testing labs and hospitals in order to develop this proposal for a blockchain system. Under this framework, certain pieces of data are shared with the other parties in the healthcare system based on their role and position. To accomplish this, the article then delineates the implementation of private data collections and other features of the Hyperledger software. A potential web–app interface is also presented and the transaction logic has been described in detail. Along with this, an evaluation of the risks, limitations and potential extension of the system has been performed
