The Basics
When the airport camera scans your face, does it compare you to a passport photo or a social media profile?
A Passport/Visa photo (from the Government database).
If you are a U.S. Citizen, do you have the right to say "No" to the facial scan and ask for a manual document check?
Yes! (Citizens have the right to a manual document check instead)
Your phone uses 1-to-1 matching (is this me?). Does the airport use 1-to-1 matching or 1-to-Many matching?
1-to-Many (It looks for you among all the passengers on the flight).
True or False: If a hacker steals your biometric data (like your face scan), you can just reset it like a password.
False! (You can't get a new face, which is why biometric leaks are so dangerous).
Some algorithms have a harder time telling people apart if they are from certain groups. What is the name for this "unfairness"?
Algorithmic Bias.
For non-citizens, the government keeps their biometric data for a very long time. Is it 5 years or 75 years
75 years!
What is the name of the government biometric database system that stores long-term identity records referenced in the retention policy slide?
HART
Legally, the government must post signs telling you that you can "Opt-Out." Where are these signs usually found?
Near the cameras (though they are often very small or hard to find—this is called "Minimal Consent").
What is the name of the cloud system used by CBP to match traveler photos against government databases?
Traveler Verification Service (or TVS)
