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

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.

      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.

      airports may be "public" in terms of facility ownership, but they are hardly "public locations". they have extremely specific conditions on entry to the portions of the facility in which this technology is being deployed. you can't simply walk in and go straight to a gate unhindered and without cost. compare that experience to walking out your front door and to a public sidewalk or street. totally different.

      they're doing this so they can conduct warrantless background checks without cause or justification on everybody that passes through ANY airport, even fully-domestic travelers, not just international ones entering through customs. we let them do this, then what's next? train stations? bus stations? local mass transit vehicles, stops and stations? facial rec at every street corner? implemented into every atm machine? if we don't stop THIS, it WILL snowball into much, much worse.

      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.

    You think that perhaps it is time to do away with the drivers license? At least for non-commercial drivers.

    The drivers license is mission creep at its worst. Had it not been for the creation of the drivers license we'd likely not have so many other interactions, public and private, needing the showing of ID. Buying alcohol would not likely require the showing of ID today if so many adults did not already have an existing ID that met that requirement. Can you imagine the outrage if everyone had to go to some state office to have their picture taken to buy a beer? I imagine a large portion of the population don't even think much of the nonsense to show a driver license to get into a bar or buy a six pack at the grocery store. I thought we wanted people that drank alcohol to not drive?

    Now we have "motor voter" laws where people can register to vote at the DMV. Can I go to the county auditor's office to get my license to drive? If it goes one way then why not the other? Then there is "Real ID" which wanted to turn the driver license into a passport. There are laws to indicate organ donation preferences on a driver license. People go to the DMV to get a non-driver identification card. So, you have no intention to drive, or are unfit to drive, but you must go to the DMV to get a card that let's you vote, indicates organ donor preferences, allows you to travel as a passenger on a bus, train, or plane, allows to to buy alcohol and tobacco, and basically everything but allow you to drive. At the Department of Motor Vehicles.

    Yes, I have a problem with the DMV taking my picture. I have a problem largely because the license to drive is no longer a license to drive. If it were then the only person I'd be required to show it to are law enforcement investigating a traffic violation. I should get an odd look for showing my driver license to a bank teller when making a withdrawal. As an experiment I once gave a different form of ID to a teller, a government issued and perfectly valid form of ID by the way, and I was asked if I had a driver license to show.

    Once after I had moved I went to buy a rifle for some hunting. My license did not show my current address so I brought ample, and I mean AMPLE, forms of identification to meet ATF requirements to buy the rifle. The store refused to do the paperwork for the transfer until I had a current ID from the DMV. (Having to show who you are at all to buy a rifle is another rant.)

You can argue on if it's been "hacked" if it's being used for things like ID to vote, or buy a beer, but I mentioned nothing about how people have abused the driver license system for fraudulent means.
