For decades now many of us have lived in surveillance societies where it’s difficult not to be within the view of a camera. When being noticed depended on the attention span of a minimum wage security guard perhaps this mattered less, but in an age of AI, the vigilance has become always-on. To address this problem the German designer [Simon Weckert] has created a fabric designed to confuse an AI scanning an image, and cause it to not recognize the wearer as a person.
The result is perhaps best described as “loud”, a pattern of saturated colors that targets the algorithms used in recognition. The tests he shows appear to work, but perhaps the most obvious thing from them is that he sticks out like the proverbial sore thumb to the eye wearing such a… vibrant garment. Also we wonder for how long it will remain effective, as algorithmic improvements seek to mitigate its attack.
This is no doubt only one salvo in what is likely to be an ongoing battle of wits. It’s certainly not the first time we’ve seen things designed to confound an AI.
they will tune them to look for exactly that – and put them at the top of the monitor stack..
It’s exploiting the fact that the pattern looks like something else to the machine, so adding it to the list increases the rate of false positives dramatically. False positives lead to false alarms, the need for human interventions, and cost.
Suppose the algorithm was tuned to find people in Ghilly suits in public spaces. Sure, you can do that, but now every other bush in the park looks like a person to the computer.
Clothes that mimic plants/flowers? Not quite so noticeable as a Ghilly suit but sufficient to confuse the system.
not like they care about false positives, these companies would sacrifice the people to baal if it meant that they could squeeze out more clients (PDs, private corporations, schools, and so on)
I would say that if the human recognition algo can’t figure out people wearing patterned clothing, it is insufficient.. Otherwise you’re going to get some kind of Warriors-style street gang that all dress in Hawaiian shirts
No need to, the self-driving cars will take care of the problem.
Specifically, the really dangerous self driving cars without LiDAR. The ones with LiDAR won’t be fooled by some patterns printed on your clothes.
I suspect that it might tell us something interesting about how the data is actually being used.
If anyone is actually running the tapes to check “people who were on the likely exit routes immediately after the murder”, or whatever the question surveillance is being relied on to answer, the anti-bot pattern might as well be a clown suit and the human analyst will have your height worked out and face neatly cropped in a matter of moments.
If, though, there’s a lot of really lazy dragnet stuff being done, because it is easy, against bot-generated extracts of tape that is never analyzed by humans(and may or may not even be retained as long as some of the machine vision results are) you might well simply not exist in that dataset without anything to indicate that this is abnormal.
Ah, Cory Doctorow et al.
Put a pebble in your shoes and the machine can’t track you by your walk anymore.
Or this from “Anon”:
“I have nothing to hide, I just don’t want you to see it.”
How come we protect our freedom by restricting it? Let me guess: “National Security” (TM).
Not for the masses. Stuff costs $90 to $120 and only comes in children’s size (max. 3xl).
I looked at the price as well as I believe the idea is interesting. But I’ll have to give it a miss. The max of 3XL is quite normal for European sizes, sadly. Making it difficult to find larger clothing for those who need it.
I may just be missing a joke, but if you consider 3XL a children’s size you guys have a BIG problem in the US.
It’s a troll. Americans don’t know the umlaut.
Unfortunately, the phenomenon is spreading globally:

Doubt camouflage will be all that effective. More to it than just an image. Movement as well. We are dealing with video, not just still images. Also facial identification is like more focused on, than the whole person. The body disguise might not be so great for some applications. Self driving cars might just need to know there is a human. Automatic doors or gates. Cameras can apply an endless array of digital filters as well. Cameras don’t entirely replace humans either. Still need boots on the ground to physically interact with issues. Cameras mostly document events. Even if they can detect an issue, an alert will still come after it happened. Might speed up response, but may still not be enough. The video is more like a witness. Ai will be a better trained witness than the average human.
Indeed. That’s why I doubt the efficacy of speed cameras for the purposes of “public safety”. They do nothing but generate revenue with a ticket in the mail a month later. They do nothing for “safety”.
The person committing the infraction just keeps on going committing the infraction, supposedly putting the community “at risk” – the quoted purpose of the laws – without immediate intervention.
In the Netherlands, people with multiple speed infractions in a time period are actively being shadowed by police to punish them on the spot, and (if necessary) confine their license.
The irony is that speeding does not increase the accident rate, which is why the people who advocate for more policing and more speed cameras do not use that statistic as the argument. Speeding itself is not all that dangerous.
The argument is rather the fatality rate, the “speed kills” argument, because while the accident rate remains largely unchanged, since it has little to do with people driving over or under the speed limit, the severity of the accidents increase with speed. That is the observation that as the average traffic speed approaches zero, road fatalities approach zero, which is also used to argue for lower speed limits all around, which frustrates people and compels them to break the law by speeding.
Speeding is a contributing factor in 29% of accidents in the US (2024 data). Your premise is just patently false.
@Bebop – how is that measured? By actually showing that the speed had a casual effect on the accident? I really doubt that. How could one even prove that most of the time?
More likely it’s just a percentage of accidents in which someone was speeding. Or.. since no one is going to admit it and make their insurance go even higher post-accident.. when the police officer who wasn’t even there guesses they were speeding.
Now imagine for a moment that there is zero connection between speeding and accidents. In that case one would expect the percentage of people that are speeding to be the same both among people in accidents and not.
29% seems pretty low. Do you think less than 29% of drivers at any given moment are speeding? Give me a break. Drive the speed limit exactly on any roads I know and almost everyone under the age of 95 is passing you.
If only 29% of drivers in accidents are speeding then I would say speeding must make one LESS likely to crash!
Yeah, yeah, global warming doesn’t exist, either. EVs are more harmful than ICE vehicles, and vaccinations make you autistic, right?
There’s tons of studies and evidence that contradict these claims, but no, “my gut feeling, my preferences and my peer group tell me otherwise”…
I won’t go into detail, as that would be futile, because, everytime, “My one obscure study (retracted) by someone with a traceable agenda, outweighs your 10, 20 or 100 studies by the leftist, green so called “scientists”!”
I’m tired, boss…
I think it was Norway (correct me) that made speeding fees indexed with the taxpayer bracket. Meaning, if you are filthy rich and caught speeding you will be paying a bloody large fee.
IMHO, We need pro-rate ALL fees in the US in the same way, and make sure tax-avoidance is NOT awarded with smaller fees.
Vehemently – VEHEMENTLY – disagree about the “generate revenue” comment.
Keep in mind one only has to do one ONE simple thing.
OBEY THE SPEED LIMIT !!! “easy peezy”.
Don’t obey, well guess what ? – you just made a VOLUNTARY donation.
No one forced you to ignore, violate, feel you are above the law. If the
sign says 25 mph – do 25 mph ! (not 40).
As a OTR driver and Uber driver. I’ve driven millions of miles staying
under the radar of traffic enforcement. The trick ? As explained – obey
the law !!
That’s fine it if was so simple.
But when they drop the speed limit for a quarter mile and put a camera right there to trap people, the line between “obeying the law” and getting milked by the road authority becomes rather blurred.
Around here, they like to change the speed limit half-way down a hill, and put the camera down in the valley, so you can’t just lift your foot off the gas pedal and coast to slow down before the camera. If safety was the concern, they’d put the lower speed limit on the other side of the hill, so people would start coming down slower. Putting it in the middle of the hill on the way down just makes people panic and hit the brakes before they run the camera.
They’re called speed traps for a reason.
For urban areas, school zones etc. with 25 mph limit, that’s another thing entirely. That’s justified. What makes the money though is the extra-urban traffic where the speed limit is rather arbitrary in the first place, and enforcing it becomes a point of revenue.
If you can pay your way out of a violation, it is not a penalty, it is a fee.
A fee is a penalty.
Speed limits are dumb. Because it will cost too much to make it smart.
Indeed. AI does not have some kind of Achilles heel where it can’t see a guy who is wearing a shirt covered in apples and melons. Would be funny if it did.
I have seen much more ambitious executions of this adversarial-visual-pattern concept (probably on this website actually) which are found by experimenting and iterating until you distill an inadvertent feature of the trained model and use it to subvert the computer vision. Those only work on a very specific model, and updating or changing the model removes the effect.
And even the effective ones aren’t effective if you, say, change your pose or angle. If you’re on video–forget it, the AI will pick you out of some (or most) frames.
COVID-19 and those masks.
Pretty sure it would be trivial to train a model to recognize faces with the mask, and it’s probably even possible to train one to figure out from context what expression is hidden beneath the mask with some passable degree of accuracy.
This is along the same lines as the “dazzle” makeup patterns meant to foil facial recognition.
Just get your cosplay mojo working and dress up as a humanoid ‘bot, you’ll be fine.
Just wear a QR code that initiates camera calibrating.
Check XKCD one about the little Bobby Tables.
Next add link for rickrolling.
Or one containing DROP TABLE table_name;
If the camera system is using SQL to monitor and keep track of objects, it might screw up the system.
Poisoning the images I see.

You know, you should probably open up a web store on some platform selling prompt injection shirts. Even if they don’t necessarily work, there’s a good amount of people who would buy those. Actually I should steal your idea and do it myself, but I’m feeling lazy tonight.
Silly.
Instead of worrying about state surveillance, the guy at Kottbusser Platz in Berlin ought to be concerned about his physical safety. The area around Kottbusser Platz is the turf of Turkish, Iranian, and Albanian clans and mafia gangs; acts of violence and shootings frequently occur there.
Good attempt at maximising Godwin’s law convergence.
Although if you aren’t involved in those circles and don’t ‘poke the bear’ by, say, walking round filming them, then they are going to leave you alone. Not saying it’s good that they’re there, but they are there and you just need to act accordingly.
Compare this to Sweden where there’s not an insignificant level (much reduced in the last few years for some unknown reason…) of innocents/mistaken identity unalivings. A very sad case of a man walking with his son when a small gang of youths said something not nice to them. As any good citizen would do, he calmly responded that that’s not how to behave. Result – unalived with a sharp instrument in front of his son.
For places like the US, the more important thing is to be realize that many of our rights (search and seizure in this case) must extend out to protect from non-governmental entities as well, and thus the government can’t do a legal runaround by buying info that companies legally can’t have.
Yep, same applies to first amendment rights (online censorship) and public domain availability (refusal to generate pubdom mickey by ai). Everything.
“Non-Governmental Organization” is one of the funniest neologisms in my opinion… It’s so obviously a lie. Like there’s really no (legitimate) reason to call yourself that except for making a shell org for the government that can do things the government itself isn’t allowed to do.
Having it not recognize your body doesn’t mean it won’t recognize your face, I have some code to test a couple of common face finding algorithms against adversarial clothing >> https://github.com/greg-randall/adversarial-pattern-test

Put a T-shirt with <|endoftext|> on it.
It is good to raise awareness, again. But adverserial “attacks” against a neural network are crafted towards a certain neural network. I this case demonstrated against a yolo object detection model. You optimize the pattern for this network and then this specific network might give lower scores when seeing this pattern.
It is unlikely this will have any effect against a different detection network.
I would even call it dangerous as this gives a sense of security while making you stick out even more.
I do not know which models this is supposed to deceive, but standard YOLOX from OpenCV detects the shirt guy just fine: https://imgur.com/a/CKhHlev
WWI ships patterns here we come again 100 years later. Cubism, too, while at it.
Back to the perpetual question – “who watches the watchers?. Second question, are we even sure those para-watchers are not being watched as well?
Who watches the watcher-blinders
seems like an ir halo hat would probibly do a better job blocking the cameras. remember surveillance cameras do not have ir filters (for night vision capability).

It is possible to print IR patterns on cloth. That would remove the “loudness” issue, and could be nimble enough to defeat the detection.
