These "passports" could prove to be a solution for travelers crossing borders, but they also come with their own set of challenges
As the number of people getting vaccinated against Covid-19 rises, it's time to review the ways that people can prove they have been inoculated when they want to cross international borders.
These so-called “vaccine passports” have been in development over the past year and are starting to go through various trials and beta tests. The passports would be used by travelers to supplement their actual national passport and other border-crossing documents as they clear customs and immigration barriers. The goal would be to have your vaccination documented in a way that it could be accepted and understood across different languages and national procedures.
As you might imagine, it's a tall order. Already, the Australian airline Qantas is talking about requiring proof of vaccination against Covid-19 for all of its passengers — both domestic and foreign— at some point in the future.
Part of the challenge is that the vaccine passports can take a variety of physical forms, such as a physical card or a mobile app. The proof could be indicated by either a QR code or a paper sticker (that would presumably be difficult to forge). I’ll focus on the digital passport forms for this post, which hopefully would be less likely to be lost and can be made part of passengers' existing travel records.
Issues to consider
There are several major issues around these passports:
Are the passports truly protecting data end-to-end? Obviously, encryption is a must. But how the encryption is applied and where it can be compromised are important details in ..
