Traveling this summer? Maybe don’t let the airport scan your face.

  • Travelers can opt out of facial recognition at US airports by requesting manual ID verification, though resistance or intimidation may occur.
  • Facial recognition poses privacy risks, including potential data breaches, misidentification, and normalization of surveillance.
  • The Algorithmic Justice League’s “Freedom Flyers” campaign aims to raise awareness of these issues and encourage passengers to exercise their right to opt out.
merde ,

For international flights, US citizens can opt out but foreign nationals have to participate in face scanning, with some exceptions.

Zacryon ,

Which exceptions?

1024_Kibibytes ,

I’ll bet one of the exceptions is having a bunch of money.

Dagnet ,

I remember when travelling in the US (Im a foreigner) there was a vip pass thingy to skip lines and enter without even talking to a migration officer (I think). Really seemed like a rich person pass

noseatbelt ,

I’m Canadian and I used to have a pass like that. It was $50 at the time and valid for 5 years.

Hey everyone, this guy’s loaded!

M500 ,

Yeah, there are two different programs. One is for domestic flights and one is for domestic and international.

I did the domestic flight one once because it was free with my credit card.

But I had to fill out some forms and interview in person.

I only got to use it once because they vip lanes were always closed.

It’s only worth it if you need to travel a lot.

Additionally, I’ve never really suffered long lines through airport security.

The long lines are typically at immigrations and you can’t skip those outside of being a diplomat or private jet rich.

Dagnet ,

They can skip it yeah, that’s the whole point of the international one

www.cbp.gov/travel/…/global-entry

And you can also skip them if an employee gives you TCC pass when your connecting flight will leave soon so you need to get there fast (had that happen to me once)

CeeBee_Eh ,

Stupid privacy people. What’s the worst that could happen? Surveillance companies that have already scoured the internet for photos of people to build a giant database of people?

It’s also not like they could ever use the hundreds of other cameras all over the airports. What would they do with all that data anyways?

StereoTrespasser ,

If you already have a passport and opt out of facial recognition, you’re only deluding yourself into a false sense of privacy. In fact, if you enter the screening area at all in an airport, you are kidding yourself if you think you can maintain some semblance of privacy. The government knows what you look like. Calm down and move on with your life.

ByteOnBikes ,

I went vacationing in another country and it was kinda uncomfortable being scanned by cameras, then scanning my passport, then moving across country lines and getting cameras and another scanning of my passport.

Imgonnatrythis ,

Fuck calming down. That’s how we got into this mess in the first place. People are to complacent with privacy. Anyone that thinks this attitude won’t lead to terrible things is a fool.

huginn ,

You’re never going to live in a world where you’re allowed to fly without photo id amigo.

CyaL8r ,

That’s not what the other user is saying - we have to fight to keep what rights we have, and maybe one day gain some of the ones we lost

kautau ,

Their message is correct but they’re mad at that “calm down” part and addressed it poorly

User 1: if you fly using a passport, the government knows what you look like, whether or not you opt out of facial recognition, being a Karen at the airport won’t help with you

User 2: Fuck that, if we are complacent, more privacy will be taken away from us

User 3: You can’t fly without a photo id

Seems to me the user you responded to knows what they are saying, and you’re both right. You don’t have a right to fly on an airplane without a legal verification of who you are. We should have a right to verify our identity without facial recognition software. But that happens with laws, not making scenes at airports

sugar_in_your_tea ,

Honestly, we should have a right to fly w/o providing ID as well. I don’t need it to ride the bus or local train, and I don’t think I need it for a greyhound bus (if I pay w/ cash). I’ve heard you can maybe get away w/o ID on Amtrak, but their official policy says it’s required.

So why are airplanes so different? Fatalities per mile on airplanes are among the lowest of any form of transportation, so I highly doubt terrorism is a significant, statistically relevant factor here. I think they do it because they can, not because it actually helps reduce risk in any meaningful way. I don’t see any basis for needing an ID for any form of mass transit, you should only need it for driving to prove that you have the privilege to do so.

I really don’t understand why law enforcement is so infatuated with checking my ID…

Yes, but Cinnabon doesn’t need to scan my face while I’m there. Every little bit helps.

dgriffith ,

You’re never going to live in a world where you’re allowed to fly without photo id amigo

Move to a different country.

Eg in Australia I can book a domestic ticket and have two interactions after that:

  • x-ray/security where they scan my carry on
  • boarding at the gate where they scan my pass.

No photo ID - or any ID really - needed. Now there’s enough dribs and drabs of information when I book the ticket and etc etc that they can identify me, but there’s nothing stopping someone from booking a ticket for someone else under their name.

GBU_28 ,

Wait are you really arguing Australia as a privacy and security IMPROVEMENT on three rest of western countries?

Cocodapuf ,

It sounds like it is an improvement for domestic flights. I don’t see anything that invalidates that argument…

JayObey711 ,

I don’t know but have you ever taken a domestic flight? Or even a Schengen one? Open border policy woks wonders for data security and also quality of life in general

That’s a strawman, who said otherwise? Showing ID is one thing, storing your ID and tracking your trips is another.

pastermil ,

You really don’t think your trip can’t be tracked?

SulaymanF ,

Is that what I said? No. Of course it can be and is tracked. But I’m not going to Hand over my biometrics and make it easier for them.

sugar_in_your_tea ,

Exactly. If they need it, they can issue a lawful order, and that has certain prerequisites here in the US. I’m guessing international airports have special rules, but I’m only going to hand over what I’m legally obligated to and force them to dance around my 4th amendment rights or face a lawsuit.

Cosmicomical ,

won’t lead

I would say we are already seeing / have already seen bad things happening because of this complacency. Buf of course worse things will happen if we don’t take measures.

CeeBee_Eh ,

The reality is that the ship for that kind of privacy has shipped a long time ago. Like a hundred years ago. The reality is that the authorities know details about every single person that passes through an airport. You can’t get in or out without a passport/identification.

There is virtually no expectation to privacy at an airport. It’s a public place that is heavily monitored for good reason. And that fact isn’t hidden in the slightest. You are legally required to freely and honestly identify yourself to the authorities.

If this was at your local bus stop, then you’d have a point. But not at airports.

Also, the serious discussion about privacy should have started with the introduction of the smartphone. That’s when the conversation would have mattered and made a difference. But that ship has sailed.

Imgonnatrythis ,

For hundreds of years women couldn’t vote and minorities were categorically segregated. Things aren’t perfect for those groups now either but those ships had sailed and it was only because some people were vocal and outraged about it. If you’re not pissed off and making a little bit of a scene about what’s happening to human rights including privacy rights you’re part of the problem. If you see somebody protesting their picture in an airport security line, don’t be one of the sheep in the line saying hurry up buddy, you’re slowing us down. Tell the people around you he’s got every right to be upset about this. A bit of awareness and resistance is a good thing.

CeeBee_Eh ,

For hundreds of years women couldn’t vote and minorities were categorically segregated.

That’s a strawman analogy. We’re not talking about privacy as a whole. The discussion here is about the supposed right to privacy at, what amounts to, a government controlled entrance point into the country. You have to identify yourself no matter which technology is being used. There’s no anonymity at an airport (from the government). Whether it’s technology or a piece of paper, you are legally required to identify yourself.

I keep saying this over and over, but if you want to talk about digital privacy, focus your energy on smartphones and the internet. The impact for privacy violation and the impact for regaining privacy rights is the most effective there.

Only a subset of any population has any interaction with an airport and the privacy implications there are next to nothing (because there is no right to anonymity there).

Imgonnatrythis ,

The more you let a government stick high resolution 3d cameras in your face and shrug it off because you’ve already lost privacy the stronger their database becomes, the more complacent you become, the more willing you become to let them do it at the train station, the post office, the crosswalk, etc. The more willing you become to put your palm on their palm reader and retina in their retina scanner when they deploy that technology. I’m not dismissing better avenues to focus efforts, I’m acknowledging the increase in surveillance and potential for abuse in the absence of any proven benefit to the people that are allegedly protected by these changes.

CeeBee_Eh ,

But they don’t need to do that track where you go and what you do. They’re already doing that with smartphones. That was my point.

And for the record, they don’t need 3D cameras for anything. A photo off of Facebook is enough. I worked in that field and developed that kind of software.

ByteOnBikes , (edited )

I’m going to assume they can photgraph you the moment you walk into the airport.

I used to be extra during the TSA body scan BS. And honestly, I felt like they won.

essteeyou ,

They’ll always win because they can just prevent you from flying.

ByteOnBikes ,

They pulled me in a private room when I refused to body scan and my bag was suspicious.

It was an extra 25 minutes. Enough to be inconvenient as they tried to find two available TSA agents willing to body check me then check every single item in my suitcase.

henfredemars ,

I tried to refuse the face scan and they looked at me like I just grew eye stalks. After a long pause, I said never mind I need to catch this flight, let’s do it.

It’s not a hill I’m willing to die on, even though I’m disappointed with the practice.

techt ,

I refused, it went fine. I had to repeat myself because it was unexpected and dudebro wasn’t prepared, and they had to turn on the other machine and wait for it to start up, but it only delayed me like 2 minutes. The more people ask, the easier it gets.

ThunderWhiskers ,
@ThunderWhiskers@lemmy.world avatar

That’s the fun part about the war for privacy. We have already lost and if you make a big deal about it they’re just going to make your life hell!

techt ,

It’s not such a binary thing as winning or losing, it’s a constantly shifting process. The only way to actually lose is by giving up – instead, consider it making it as hard as possible for your privacy to be infringed upon. Sometimes it’s more inconvenient, but what makes us such a farmable populace is our reluctance to be inconvenienced. Be good at being uncomfortable.

sugar_in_your_tea ,

Yup, go to the airport early, wear something like reflectacles and a mask, and record everything. Who knows, maybe they’ll violate your rights and you can find a lawyer to sue them to recoup some of that inconvenience.

Grandwolf319 ,

And we lost it under W and the patriot act.

explodicle ,

I still opt out of those scans to this day. Why stop?

credo ,

I’m okay with the TSA scan (pre-check) since… you know… they already have you if you took a picture for your ID.

Those “clear” people however. Who TF thinks it’s a good idea to hand your biometric info to a corp?

AbidanYre ,

I’m sure the government would never let biometric data be compromised. Right?

credo ,

As I said. They already have it.

Isn’t reducing the size of the dataset worth it? I’d rather them have a picture from three years ago than a new scan every month or two.

Limonene ,

How did you get into TSA Pre without providing fingerprints? I tried once, and they strictly refused to let me apply because I wouldn’t give fingerprints.

credo ,

Well, I’ve had DLs in multiple states and they all required fingerprints. The little digital ones. Maybe that’s not the case everywhere though.

ThunderWhiskers ,
@ThunderWhiskers@lemmy.world avatar

Oh, weird. They don’t require prints for a DL in TX, but we’re already closing in on an authoritarian state anyways. I didn’t know this was a thing.

toddestan ,

It probably has to do with whether the driver’s license is Real ID compliant or not. Here in Minnesota, you have the option of getting the Real ID license that can be used as a federal ID card for things like flying, or the regular old driver’s license which soon will really only be good for showing you’re allowed to drive a car.

I only have the regular driver’s license so I don’t know what all getting the Read ID involves, but having your biometric data scanned and stored seems like something they’d require.

Oni_eyes ,

Texas is real id compliant. Has been for like seven years iirc

sugar_in_your_tea ,

I’m in Utah and have a “real ID” or whatever (the little gold star) and never had my fingerprints taken, eyes scanned, etc. If they required that, I’d say no and just use my passport instead, which also didn’t require biometrics.

Zectivi ,

Clear is now a TSA “vendor” for the precheck process. The machines they use for the sign up process - at least the airport I was at - don’t have the eye scanning camera in the kiosk.

The Clear representative I was asking questions of had said they don’t require eye scans for Clear, though that is the default. People can ask to use just fingerprints, which he said does disrupt the terminal process as the agents don’t think to ask if fingerprints were what was registered when the eye scans fail.

I am not advocating for Clear. I refuse to use them. I simply do want to call out that they are one of 3 who handle the process for the TSA now. People do have a choice of which of the three to use.

Yes they have facial recognition, the cameras are visible but you don’t notice them.

It isn’t necessarily. Had a police officer greet me by name once (had never interacted with this officer or the station they were from). They’ll have the data necessary to identify you by sight. If you’re a British citizen the British government most likely has a photo of you somewhere if you have any photo ID, not to mention if your face is known to the state through other means eg through interaction with the criminal justice system.

Trust me you’re already a recluse relative to most by being on here. If you observe what passes for a “normal” “person” these days, they will endlessly scroll algorithmic ai-generated incomprehensible horrors on Tiktok, then purchase something through an ad from temu, they do not think. They are gone.

But once you stop worrying that you may be saying no to experiences too much purely on principle, then you’re free to go even further and eradicate surveillance capitalism influence from your life altogether. One day you can ascend to even go smartphone-free.

rottingleaf ,

One day you can ascend to even go smartphone-free.

Ascended to that in late 2014 because using a smartphone was a trigger for my anxiety.

Back to using those since 2020 because of WhatsApp calls, apps for every shit and such being needed in life.

How is that much different from scrolling Lemmy? They are both social media

Cryophilia ,

That’s like saying a Subaru and a submarine are both modes of travel.

LainTrain ,

Because Lemmy is Free, as in Libre and as in free beer, it is open source, and on top of all that, it’s not run for-profit by a single large corporate entity, it’s decentralised structure precludes that by design.

There is nothing actually wrong with websites or forums like this or “social media”, not anymore than there is anything wrong with atoms even if humans found a way to make a weapon of it.

In this case technology is weaponized by capitalism, and they’ll do anything to make you think it’s anything but the corporations who are to blame, misinformation on top of misinformation.

The “mental health effects” of social media or smartphones are all just corporate distractions from the fact all those are really effects of capitalism. Even cryptocurrency isn’t actually bad inherently, I use monero all the time, it’s a great idea actually, especially where power consumption is addressed, but capitalism made it a speculative assets and state backed players wrestle for control. AI too. Open source LLMs benefit everyone, but the lack of tech literacy turned progressives against it and the played right into OpenAI and the rest of those scumbags’ hands.

The fact that those who aren’t immersed in tech don’t know this is why all is lost. For the common man - they won, and it’s all black box products made to exploit people to the last drop.

JackbyDev ,

If you observe what passes for a “normal” “person” these days, they will endlessly scroll algorithmic ai-generated incomprehensible horrors on Tiktok, then purchase something through an ad from temu, they do not think.

Can you just like, not be so damn condescending and elitist? Literally saying people who use TikTok and purchase stuff from Temu are sub-human…

LainTrain ,

Yeah I’m sorry, I just feel pretty strongly about this I guess and Lemmy is one of the few safe places to vent to like-minded folks.

To explain myself a little: It’s not the “normies” that the techy people hate, it’s the perverted messed up world those less savvy in technology live in and everything about it, and with how much we’ve learned to circumvent corporate control it’s often a culture shock to see that people just take it, even stuff like online ads or algorithmic content feeds, stuff I haven’t experienced in probably a decade, like as if that’s just normal, and the sad part is it is for so many.

Imagine if most of the world population was just falling for pyramid schemes or other blatant financial scams constantly. That’s how it feels.

It becomes all too easy to blame the people rather than the systems that led to this, and sometimes it just feels like nobody outside of the hacker circles really gives enough of a shit to take control of the few things they can, and this is late stage capitalism, so I can’t really blame them, we’re all so tired just trying to survive.

JackbyDev ,

If I thought people were just taking it I’d agree, but a lot of people genuinely don’t know what things like ad blockers are. Much less something like using ad guard dns or pi hole. They’ve just never heard of it.

LainTrain ,

But honestly, how?

JackbyDev ,

Tell them!

Wilzax ,

I figure that by being in the airport there’s enough footage of my face from security cameras that I didn’t consent to (other than by being in public) that the scan of my face while boarding is moot.

Opting out of this face scan in particular is like using Chrome to browse the web, but searching with DuckDuckGo “for privacy reasons”

Knock_Knock_Lemmy_In ,

There’s probably a huge difference in resolution.

Wilzax ,

Sure, but what’s stopping them from just adding whatever high res cameras they want in their terminals and jet bridges anyway? How can we be sure they aren’t already doing that? The only thing the face scan does that those cameras can’t is require you to lower your mask.

Spedwell ,

As the article points out, TSA is using this tech to improve efficiency. Every request for manual verification breaks their flow, requires an agent to come address you, and eats more time. At the very least, you ought not to scan in the hopes that TSA metrics look poor enough they decide this tech isn’t practical to use.

Cryophilia ,

More likely they’ll just remove the option to opt out

Knock_Knock_Lemmy_In ,

Sure, but what’s stopping them from just adding whatever high res cameras they want in their terminals and jet bridges anyway?

Budget probably.

ulterno ,
@ulterno@lemmy.kde.social avatar

Yeah, because just adding high-res cameras is not good enough.
They will need a good quality data transfer network with it and also have to use higher powered computers for data processing, to get whatever they want out of those videos.

They might even have to pay shriek C++ devs to rewrite their Python prototype into a more efficient production code (and considering how hard it is to find devs that actually know what they are doing…).

TonyOstrich ,

There is a reason I wear a large hat and a mask when walking through the airport and generally keep my head tilted down. I also wear large sunglasses, but that’s as much because every airport has at least one giant wall that is nothing but glass and inevitably I will walk around a corner and get face fucked by the sun. The privacy is just a bonus 😅

Alph4d0g ,

Opt out. If we don’t exercise our rights, we lose them.

"What if they retaliate and make life difficult for me? "

That’s both illegal and against policy. If someone delays your right to travel for this specific reason, delay their job by asking for their supervisor and their name and employee number. Then file a complaint. That will dissuade that public servant (and their leadership) from exhibiting such behavior and encouraging it respectively.

"But they are capturing your image in 10 skillion other public locations."

  1. Sure, and you have the option to create your own privacy in public.
  2. Further, what’s the real purpose of the scanner at the TSA check if they already have that detailed image of your retina, your facial pore patterns and whatever the fsck else they store? They don’t have that level of detail yet on CCTV.

If you don’t care, then that’s fine. Some people don’t mind the slow encroachments on 4th Amendment protections. Cool. Others do. Cool also. That’s why we can opt out.

Petter1 ,

There should exist a law that orders privacy by default forcing all this intrusive stuff to bi opt-in instead of opt-out. With data, it is often to late if it is only opt-out…

Alph4d0g ,

Agreed. This was rolled out without any regard whatsoever for people’s interest in data privacy. That kind of entitled behavior from any government agency is just plain gross.

retrospectology ,
@retrospectology@lemmy.world avatar

I did this during an international trip last year coming back into the country. The guy mostly seemed confused and kind of suspicious, but it was nbd.

They will potentially take you out of line to a side room to hand you off to someone else. It seemed to be an area where they deal with any oddball kind of things. There was a lady ahead of me who was more raucus and upset about some issue with her ID. The guy who checked mine mainly seemed kind of bemused, like it was unusual.

Be prepared for “We have the biometric data from your photo already, why do you care?”

You’re not obligated to give them a super detailed justification. Just remain polite and unconfrontational, and explain that you prefer not use the system as long as the right remains afforded to you to opt out.

(Note, this right only extends to US citizens)

TragicNotCute ,
@TragicNotCute@lemmy.world avatar

I have global entry, so they already have my biometric data. I'd love to not here scanned, but this point it wouldn't be anything they didn't already have.

NOPper ,

It’s the only real way to push back that other folks will notice if enough of us do it.

Last time I went through DC a few weeks ago they were using these. I saw a sign saying you’re welcome to opt out. Nobody even questioned what they were doing and were just going along. When it was my turn I politely said I’d rather not do the scan. Dude just glanced at my ID and waved me through. The next few folks behind me blinked and said they didn’t want the scan either. If enough people push back it can at least maybe slow down the normalization of constant surveillance.

techt ,

Put your foot down everywhere then – it’s a fallacy to think that it’s not worth it to resist data harvesting because it already gets collected “everywhere” anyway, take one step at a time to make it harder and harder. Opting out of this is just one step.

I’ve never posted any pictures of my face online. But I’m sure many data brokers have them. And some family members many years ago I’m sure posted some.

ealoe ,

Dumbass article, if you go to an airport your face is all over the security cameras and the checkpoints delete your image immediately after scanning so they are the least of your worries.

BaroqueInMind ,

the checkpoints delete your image immediately after scanning so they are the least of your worries.

I’m going to need a source on this bullshit lie.

ealoe ,

Source: the signs on the device itself at an airport I saw last week, also the TSA website www.tsa.gov/digital-id

The photo is immediately deleted unless clear signage is posted ndicating that the checkpoint is undergoing testing as results may be retained for up to 24mo.

BaroqueInMind ,

How do you know it is auto deleted?

What if it relies on specific personnel to actively purge the database? What if said personnel are poorly trained, low pay, exteme limited time, and simply does not care?

How likely does a TSA agent fall under all of those criteria? (Hint: very likely)

Edit: here’s the fucking clincher directly from their website

During periodic testing and development, TSA and DHS Office of Science and Technology (S&T) may retain passenger data for up to 24 months.

I am pretty sure I read somewhere that they plan to test this system for the next decade. So technically they don’t delete anything due to being a long as fuck period of “testing”.

aodhsishaj ,

That testing period, plus 24 months

ealoe ,

Well if that is the case at your specific airport, you’d know because it would say as much on the sign. You know, like it says in the sentence immediately following the line you quoted.

slickgoat ,

The game was lost for me when I started getting fingerprinted at certain airports. This privilege used to be reserved for suspected criminals. Now we’re are all suspected criminals on a default setting.

player2 ,

You’re already on hundreds of cameras by walking into any airport in the world. Do they need your consent to run facial recognition software on the security footage?

Uli ,

I used to work for a company that did various kinds of biometric recognition. I unfortunately was paraded past these cameras many times for testing purposes, so my face was compromised many moons ago.

We had two kinds of products we installed in airports. When looking at large crowds most airports wanted cameras that would monitor the flow of traffic, determining if there were any bottlenecks causing people to arrive at their gate (or baggage claim) after their luggage.

The other product was facial recognition for identification purposes. These are the machines you have to stand right next to. There are various legal reasons airports did not want to use any crowd-level cameras for identification. They hadn’t obtained consent, but also, the low resolution per face would lead to many more false positives. It was also too costly.

But we did have high def cameras installed in strategic locations at large music halls. These private companies were less concerned with privacy and more concerned with keeping banned individuals out of their property. In those cases, we registered faces of people who were kicked out for various reasons and ignored all other faces.

My point I guess is twofold: first, you might not be facially tracked in as many places as you think you are. Second, eventually you will be and there’s not a whole lot we can do to stop it. For many years, Target has identified people with their payment card, used facial recognition to detect when they return to the store, and used crowd tracking to see where in the store you go (and sometimes they have even changed ad displays based on the demographics of people standing nearby).

Mostly, you will be identified and tracked when there is financial incentive to do so.
