On the podcast this week, the hosts chat with Dr Chris Hicks and Dr David Butler, who work as post-doctoral researchers in security and cryptography at The Alan Turing Institute. In an episode that focusses on one of the projects the institute has undertaken to help tackle the pandemic, they discuss how to build a privacy-preserving system for issuing and verifying Covid19 antibody certificates, a technology that could be used to help with the easing of pandemic measures in some scenarios.
