The SARS-CoV-2 first surfaced
in 2019 in China and later spread across the globe causing a pandemic.
Immunisation has thus far been considered to be mankind’s weapon of
choice in the frontline fight against the virus defined as Covid-19.
Mass vaccination programmes carried out by nations are closely related
to public health information, data safety and data security. As
countries roll out the immunisation efforts, cyber offenders try to
exploit people’s personal health data and inoculation records while
citizens can also be exposed to fake vaccine certificates issued by
hackers. To prevent such any data breach or data exploitation, an
effective system is urgently required to be in place that ensures the
maximum security at a time of the unprecedented global crisis.
Blockchain can be the perfect solution in this case thanks to its
transparency, trustworthiness, and decentralised operations. We have
proposed a blockchain based framework for covid 19 vaccination process
to provide data immutability, transparency and correctness of
beneficiary registration for vaccination, eliminating identity thefts
and impersonation, tamper proof self-reporting of side effects, person
identification and vaccine certification.
