Once facial recognition becomes commonplace, the impact will be huge. “What were your whereabouts on the night of June 5th?” “I was at home all night.” “You’re lying. We have confirmation your face was recognized at the gas station, grocery store and bank between the hours of 7 and 9pm.” That sends a shiver down my spine.
Do you regularly lie about your whereabouts to the authorities? Or just feel that you should have the right to do so without being found out"

>> The scan takes fractions of a second and has shown to be 99 percent accurate during testing >> Presumably it's 99% effective at matching random faces to the photos I think what they mean is that they carried out laboratory tests where a test subject stood facing the system's camera and the system tried to match their face to a database of pictures of peoples' faces, then decided whether the subject's face matched…
> e.g. use a small database, rather than the entire US passport photo database plus photos of visiting foreigners Doing so would be wildly inefficient. You need your passport to check in for your flight. When boarding the plane, you don't need to check someone's face against the entire passport database, only against the passports which have been checked into the flight, which is particularly important in terminals w…

So that's definitely not just the passports that have been checked into the flight- foreign nationals in particular may have entered the country at any time and place other than before boarding a flight at Dulles.
Which is why there are privacy concerns in the first place- because it can be used to track the movment of people across multiple trips.

> they don't take your photo if you're a US passport holder This is very much in the "you don't have to go through the body scanners" at the airport category. By default they take your photo and fingerprint, even if you're a US citizen; the specific language on CBP's website is: "At this time, CBP does not require U.S. Citizens to have their photos captured when entering or exiting the country. U.S. Citizens who requ…
> By default they take your photo and fingerprint, even if you're a US citizen Photo, yes; fingerprint, no. Every customs station I've been through when re-entering the US has taken photos but not fingerprints. (They do require fingerprints from non-US-citizens.)
