Panel Discussion

Digital Vaccination Passports

The Covid-19 pandemic has created many challenges, some of them with potential technical solutions. Last year, one of the main international discussions was how to assist contact tracing efforts with digital means, and the research and mobile device communities together came up with a decentralized, privacy-preserving solution to record mobile phone proximity and help mitigate spreading chains through infection alerts. Triggered by the more recent availability of vaccines, the next global question is how to digitally assist in verifying the vaccination (or antibody, testing, etc.) status of individuals. The same challenges to data privacy remain, especially in the balance of international travel and local, frequent presentation of vaccination certificates throughout daily life. Finding the best trade-off between unforgeability, usability, and privacy is difficult.

In this panel, international experts with various professional backgrounds and different points of view will discuss the currently proposed solutions and their expected regional as well as global impact in the next few months.
