Is Homeland Security's Face-Scanning At Airports An Unreasonable Search? (technologyreview.com) 146

schwit1 shares an article from MIT's Technology Review: Facial-recognition systems may indeed speed up the boarding process, as the airlines rolling them out promise. But the real reason they are cropping up in U.S. airports is that the government wants to keep better track of who is leaving the country, by scanning travelers' faces and verifying those scans against photos it already has on file... The U.S. Department of Homeland Security has partnered with airlines including JetBlue and Delta to introduce such recognition systems at New York's JFK International Airport, Washington's Dulles International, and airports in Atlanta, Boston, and Houston, among others. It plans to add more this summer...

As facial-recognition technology has improved significantly in recent years, it has attracted the interest of governments and law enforcement agencies. That's led to debates over whether certain uses of the technology violate constitutional protections against unreasonable searches... Harrison Rudolph, a law fellow at Georgetown Law's Center on Privacy and Technology, and others are raising alarms because as part of the process, U.S. Customs and Border Protection is also scanning the faces of U.S. citizens... They say Congress has never expressly authorized the collection of facial scans from U.S. citizens at the border routinely and without suspicion.

"We aren't entirely sure what the government is doing with the images," the article adds, though it notes that the Department of Homeland Security is saying that it deletes all data pertaining to the images after two weeks. But Slashdot reader schwit1 is still worried about the possibility of an irretrievable loss of privacy, writing that "If the DHS database gets hacked, it's hard to get a new face."

    Airports are very public locations so there's no reasonable presumption of privacy under the 4th Amendment. This is not an unreasonable search. Now, for general policy reasons I by and large *don't want the government doing this* for what amount to privacy concerns as well as concerns about too much data being gathered with little oversight, but that doesn't make it an "unreasonable search" in any legal sense. It is possible for something to be a bad idea without it being unconstitutional.

      People are not, in general, boycotting airports. Nor are they refusing to vote for candidates that are pushing for more invasive security theater.

      Therefore, the government will continue to push for ever-more invasive security measures. They will not stop until they are stopped. The only thing I don't understand is why people think this is cynical. This is how the world has always worked.

      I guess it may meet the definition of a public place. But it doesn't SEEM like it should since everyone inside the secured area has paid a rather large fee to be there, there is security to keep others out, etc. The location is owned by a company. It seems like it would be a private place. But if the definition of public is that anyone not on the 'no fly' list who ponies up a large fee and doesn't carry weapons or even water can enter a privately owned facility - then it is a public place.

    • the reality of walking through the airport without having to show a boarding pass is going to win this argument in the end

      Really? Showing a boarding pass is just about the least onerous thing you do in an airport. If it allowed them to reduce the security theatre required then I'd say it is perhaps worth it. However, since a boarding pass contains information about your seat, gate number and boarding time I am still going to want one whether or not I have to show it and once you have it showing it to someone is not really that hard.

    • Consumers want what? Consumers want speed and convenience. I don't think there's any consumer that at all thinks the process of showing an ID or a boarding pass would actually improve either of the two things they care about.

    No.

    Your face is already visible to the public. And if it's an issue of tracking people _leaving_ the country, there are numerous ways to leave with no supervision whatsoever. The country you are entering may want to run a check, which is perfectly reasonable.

    As for the issue of collecting facial scans, I assume that they are capturing an image for the purpose of facial recognition. Meaning that they already have a picture of you on file somewhere. Which has been true since the first person ever sat for a passport or drivers license photo.

      >Which has been true since the first person ever sat for a passport or drivers license photo.

      Yeah but those were done with very different technology.

      For instance, my state added the photo to the driver's license but, by law, didn't authorize or intend to create a central catalog of photos. The law merely said the state could add a photo to the license. Years later when they went to digital licenses, the state just adopted the central database. And as time has gone on, they have increased the quality of the photos captured so they can be used for biometric matching. Several generations of technology improvements have occurred and yet the state still never got authority to keep a central photo archive. Taking a mile from an inch.

      In the same way, the passport has you send in two pictures. But there is a world of difference between operating a central passport photo database with facial recognition, and having a paper file somewhere with the 2nd picture sitting in it, which can only be referenced manually by a human.

If they automate a deep dive into your background then somewhere along the line they probably have crossed a line violating 4th amendment rights. But merely attaching names to faces in a place where they are already asking for your id anyway probably isn't too big a deal. It just automates basically what they are doing already.

    The checking of ID / boarding passes has never been the limiting factor when boarding the plane. All this would achieve is moving more people from the queue outside the gate to the queue inside the airbridge or worse on the tarmac as we wait for several hundred people to one after the other get their shit together, find some space in an overhead compartment, sit down, and then stand up again when the next person needs to move past them.

    If airlines wanted to speed up boarding that would abolish priority boarding and board by seat row only and additionally actually enforce which rows they are boarding. Though they pretty much have given up on priority anyway since every schmuck has a priority card now. Heck I flew in a flight once where there were 7 people who *didn't* have priority boarding, and then some business class passenger got upset when the airline refused to let him push infront of the other priority passengers.

    The more the USA tries to 'fight terrorism' with these kind of measures, the more the terrorist will win. Terrorist organisations come and go. Look back in history. IRA, ETA, Osama Bin Laden, Taiban, Al-Qaida, Boko Haram, Islamic State, and the list goes on. For one a terrorist, for the other a freedom fighter. But, they never last. The only thing changes is the way countries deal with it. If you look at the amount of terrorist attacks over the years, you come to the conclusion that the world has become a saver place. Yes, although we hear more of terrorist attacks due to better news coverage, there are less terrorist attacks today then 10 or 20 years ago. But governments somehow don't see that. They come up with more and more 'security' measures. But those measures don't make this world safer, they only take away freedom and privacy.

    The USA has very strict anti-terrorism measures, but the attack in Boston still happened. The anti-terrorism measures in Europe also become more strict, but the attacks in Madrid, Brussels and Paris still happened. Airports are becoming a hard target, so terrorist move to other tactics, like simply taking a van and drive it into a crowded place. We have to accept that you can't stop it.
