I can see the logic in this but two issues occur: 1) do you get immunity after you have had the virus? and 2) could this lead to discrimination over time against those who haven’t had the virus if it brings immunity?
Tech firms are in talks with ministers about creating health passports to help Britons return safely to work using coronavirus testing and facial recognition.
Facial biometrics could be used to help provide a digital certificate – sometimes known as an immunity passport – proving which workers have had Covid-19, as a possible way of easing the impact on the economy and businesses from ongoing physical distancing even after current lockdown measures are eased.
The UK-based firm Onfido, which specialises in verifying people’s identities using facial biometrics, has delivered detailed plans to the government and is involved in a number of conversations about what could be rolled out across the country, it is understood.
Its proposals, which have reached pilot stages in other countries, could be executed within months, it says. The firm could use antibody tests – proving whether someone has had the virus – or antigen tests, which show current infections.
Digital identity experts say they are in the “discovery stage” of what could be tailored for the UK government, but developing a type of health certificate through app technology is gaining traction.
