A Critique of EU Digital COVID-19 Certificates: Do Vaccine Passports Endanger Privacy?
Harry Halpin · Proceedings of the 17th International Conference on Availability, Reliability and Security · 2022
Do COVID-19 vaccine passports come at a fundamental cost for personal privacy? Reviewing proposed COVID-19 credentials from a security and privacy standpoint raises concerns that make deploying COVID-19 digital certificates difficult at best. A closer look into the privacy of the EU Digital COVID-19 certificate presents a fundamental contradiction between two essential security properties: unforgeability and privacy. A substantial reconsideration of the very concept of vaccine passports may be needed to preserve fundamental privacy rights.
