Design of a Vaccine Passport Validation System Using Blockchain-Based Architecture: Development Study [open pdf - 1MB]
From the Abstract: "COVID-19 [coronavirus disease 2019] is an ongoing global pandemic caused by SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2]. As of June 2021, 5 emergency vaccines were available for COVID-19 prevention, and with the improvement of vaccination rates and the resumption of activities in each country, verification of vaccination has become an important issue. Currently, in most areas, vaccination and reverse transcription polymerase chain reaction (RT-PCR) test results are certified and validated on paper. This leads to the problem of counterfeit documents. Therefore, a global vaccination record is needed. [...] The main objective of this study is to design a vaccine passport (VP) validation system based on a general blockchain architecture for international use in a simulated environment. With decentralized characteristics, the system is expected to have the advantages of low cost, high interoperability, effectiveness, security, and verifiability through blockchain architecture."
