Hey, that's my line.

Your license plate can also be used to track you

[–] NarrativeBear@lemmy.world 14 points 1 month ago (1 children)

You are correct, the only thing worth mentioning is when the laws were created/written it did not account for someone creating a database that is easily searchable/queried to infer all these extra habits of people.

Its one thing visually seeing someone over and over walk or drive by your house while you sit on your porch. It's another thing to now know where they came from and where they went if you were able to sit on every porch at the same time in a town or city.

This is why police tails need to be granted by a judge, but a interconnected network of cameras at the moment does not recieve the same scrutiny.

[–] FireRetardant@lemmy.world 4 points 1 month ago (1 children)

I think part of why the cameras don't have such scrutiny is the city often has signs stating they use the cameras and will list their locations. This gives a somewhat implied consent from the driver, idk if it holds up in court but its similar to a sign at a store saying you're on CCTV. The sign doesn't say the CCTV could be used to track and monitor you but its implied.

They mention this in the article. The difference is that since the tire sensor sends out an RF signal, direct line of sight isn't necessary. You could throw a tracker up on a roof and grab signals from a block over.

The missing part may be tying that signal to a specific car, but say your car gets pulled over - they could read your tires' sensor ID and compare it to where they captured it and bam! Now you're fucked.

[–] Ilovethebomb@sh.itjust.works 38 points 1 month ago (1 children)

Your car has a series of numbers and letters on the back of it that are unique to the vehicle, and can be used to track you as well. There are even automated cameras that can do this.

Tracking a vehicle is easy, and always has been.

[–] FireRetardant@lemmy.world 9 points 1 month ago* (last edited 1 month ago) (1 children)

However, the researchers found that these tire sensors also send a unique ID number in clear, unencrypted wireless signals, meaning that anyone nearby with a simple radio receiver can capture the signal, and recognize the same car again later

Its not quite the same ball game. Sure its not great that the government can track easily with ALPRs, but this type of tracking is available to nearly anyone and could be used for significant crimes like stalking or human trafficking. It can also be done without a sightline of the car, unlike a camera system.

A local city proudly mentioned on the news that they had a system that could track TPMS sensors. Pretty much all cars after 2008 uses TPMS sensors that each broadcast a unique identifier to the car. They aren't hard to remove, and you can buy valve stems that fit your car (0.452 hole) at any auto parts store.

EDIT: The sheer amount of replies to this post days later that basically state "This is too hard to do, and it won't work anyway, so you are stupid to try and shouldn't do it", all from people who clearly have no real idea how the TPMS system on a car works, have confirmed for me that I was correct in spending a half hour removing these devices.

[–] dual_sport_dork@lemmy.world 53 points 1 month ago (16 children)

By "aren't hard to remove" you actually mean requires dismounting the tire from the rim, remounting it, and then balacing it. This is far beyond the capabilities not to mention equipment of the typical layperson. Plus, your state is likely to conveniently fail your car on its next inspection for a nonfunctioning TPMS system, same as your check engine light.

If you're going to go the distance anyway, get your tire shop to mount aftermarket Autel sensors in your rims. Using the readily available diagnostic tool, you can occasionally reprogram those (wirelessly!) with a set of random IDs and then also program your car to use them. You'll be a lot tougher to track if your signature is different every week.

I'm not about to do this just yet, but I do have the tool for more mundane purposes and I only paid around $200 for it several years ago.

[–] Grostleton@lemmy.dbzer0.com 7 points 1 month ago (6 children)

It seems most states with mandatory vehicle inspections don't fail for TPMS problems.

Dude, my car has GPS and a 4G internet connection as well as my android phone and my work required iPhone ... In a world like this, Tyre sensors are probably not required to track me.

[–] BeardedBlaze@lemmy.world 7 points 1 month ago (5 children)

On the other hand, my 21 year old vehicle has none of it, and my GrapheneOS phone isn't tracking me either. We didn't all just give up like you did.

[–] Ulrich@feddit.org 6 points 1 month ago

Does your GrapheneOS phone have a SIM? Because if not, the cell towers are collecting and storing your location.

[–] partofthevoice@lemmy.zip 6 points 1 month ago

I spoke with my landlord about removing power to the home security cameras, because they were Ring. He obliged my request, but I later discovered that he (in private) regards my preference as that of a rebellious teenager in need of a cause. I had to let that sink in… I’m a rebel without a cause because I don’t sip from the same koolaid as he does. Wow.

among the hundreds of other things that "could be tracking me"

at this point I wouldn't be surprised if my inner most thoughts weren't already uploaded to some giant government server.

They discovered a thing that everyone's known forever. Here's Bruce Schneier in 2008

License Plates, Vin Numbers clearly available on the dash, Tire Sensors, Bluetooth MAC, WIFI MAC, Cellular IDs for most even if you don't pay for the service.

It's an interesting thing to point out, but we're mostly driving around with much higher power sensors than the pressure sensors.

[–] chillpanzee@lemmy.ml 7 points 1 month ago

Not to mention the cell phone most of us carry.

Because each sensor broadcasts a fixed unique ID, the same car can be recognized repeatedly without reading a license plate. This makes TPMS-based tracking cheaper, harder to detect, and more difficult to avoid than camera-based surveillance, and therefore a stronger privacy threat.

This seems like a real stretch.

Cameras and automated license plate recognition are absurdly cheap at this point. And cameras have much greater range and reliability than whatever wireless signal interception this is, which the researchers have said is effective up to 50 meters.

Meanwhile, from the office where I sit (which happens to be more than 50 meters above street level), I can see a highway and read the license plates of all the cars maybe 100-300m away. Plug in a cheap phone as a simple webcam and I can probably log all the license plates that drive by, maybe even correlate that to makes and models of vehicles for redundancy.

And who's going to detect that I've got a cell phone camera pointed out of my office window, or that I'm running that type of image recognition on the phone?

All these "unintentional" tracking devices begin to look intentional.

Eh, the fucking cellular modems in my car that stream the camera data for training can be used to track me. Hell, the anti theft tracker that I paid money for can be used to track me.

Flock in a few months: “introducing a license plate reader that doesn’t need to see the license plate. The magnet leaf you got on Amazon to get through red light cameras won’t be enough to fool our dystopian surveillance system anymore”

[–] ebolapie@lemmy.world 6 points 1 month ago

Flock right now advertises that they can track vehicles by bumper stickers and cosmetic damage.

[–] Doomsider@lemmy.world 8 points 1 month ago (4 children)

Jokes on them, those tire pressure sensors are the first thing I don't replace. I just visually check my tires and put a pressure gauge on them if they look suspect.

[–] how_we_burned@lemmy.zip 5 points 1 month ago

Or just replace your tyres with ones with non sensor.

That said it is a little annoying. My dash is forever telling me it can't talk to the tyres.

Ha the undisableable built in gps does that much better.

[–] bluGill@fedia.io 5 points 1 month ago (2 children)

Depends on the attacker. The GPS is better if you have access to the car, but getting that is hard. Any idiot with a radio can read the TPMS sensors of every car going by - there is nothing that even slows them down.

I made sure my car doesn't come with a cellular modem. But I didn't knew about the pressure sensors.
