Blockchain Based Health Information Exchange Ecosystem: Usecase on Travellers

ABSTRACT

Various international initiatives have been launched in 2021 to generate digital vaccination certificates to address challenges faced by travellers exposed during COVID19. While COVID19 has impacted multiple industries where alternate solutions have emerged at competing rates, airline industry in particular have been hit hard due to highly regulated protocol. Owing to its unique characteristics of transparency and decentralization, block chain technology provides an opportunity to create smart solutions for travel industry. We present a solution that describes a scaled, blockchain-based infrastructure for exchanging COVID-19 pandemic travellers’ history and vaccination status in a secure manner. The proposed approach ensures the travellers are coronavirus-free and check their COVID 19 history and vaccination status across the borders and immigration in particular. The framework employs a permission blockchain and Proof of Authority to check vaccination status on airports using the smart contract. It provides a distributed infrastructure for national and international healthcare systems, to check digital vaccination certificate and individual vaccination history and their verification by relevant stakeholders, such as airport securities, health authorities, governments, border control authorities and airlines. © 2022, Springer Nature Switzerland AG.
