IT's easy to replace a phone, a car not so much

Several of my cheapest cars (and quite a few of my cheapest motorcycles) have cost me less than my most expensive phones.

Car titles (and thus vehicle transactions) are public record.

This isn't a generic data privacy counter-measure or concern. This is specifically targeted against stalking, which is pretty much one of only a few cases where this kind of thing would be used against you. Specifically the case where the perpetrator will place a device in or on the victim's car.

Knowing where you are is useful. Knowing where you _aren't_ is equally useful. I can imagine half a dozen ways to use this data against you in all kinds of settings. Sales, divorce, employment, espionage against your employer, burglary, and basic blackmail.

It doesn't necessarily say where you aren't. What if you get in somebody else's car? (Not uncommon for me as we typically carpool to trailheads.)

Interesting research, but the paper does not address the contribution to the arms race of good vs bad. The criminals will likely use this technique to find legitimate car trackers before stealing the vehicle.

Did you not notice the motion sensor bit? Their technique does not work against a stationary tracker because it's not going to say anything. Thus you can't check out the car before you steal it.

What the bad guys do is steal the car, then leave it somewhere as soon as possible and see if anyone comes for it.

Better hope your stalker isn't friends with a law enforcement officer either: https://deflock.me/

They also used to monitor MAC addresses from various wifi access points, the MAC addresses of your computer don’t change. But now I think the vendors started fixing that.

I noticed that in Abrego Garcia's recent indictment they were able to figure out he was in 2022 based on ALPR pulls that showed he was actually putzing around Texas. My understanding was most ALPRs were being stored for no more than 30 days but apparently that isn't the case, since it appears they did not start to build the trafficking case until this year.

There's networks of these things, so you can't trust what is said. The host agency may keep for 30 days, but exchange data with third parties, through organizations like NLETS, private collaborations and informal exchange. I'd assume with NLETS searches that the Feds have an overwatch capability and spy on the spies so to speak. This stuff started with "drug corridors". Police and Feds can and do track vehicles on th…

Why don’t they just use facial and gait and heartbeat recognition everywhere? London and other cities already have CCTV cameras, and an AI can quickly figure out wherr you are. In China it has been deployed at scale!

Simply putting a fake plate would bypass that. Truckers usually have a pulley system on their plates to avoid tolls, so maybe more normal drivers will implement such a system or find a way to create something that messes up their camera OCR.

If you're going to try and track this stuff for real, keep in mind most devices like this use motion sensors to go into low-power mode when stationary and only transmit on the move.

Also that some devices log data locally and require manual pickup + review to avoid detection. Also LEO have been known to temporarily disable such devices when people do scans to detect them for Undercovers.

Any more info on this?

That would probably flag you immediately for a plate that doesn't match the car, a plate that does match but seen in two places that would be impossible to travel in that time.

I don't think cars should have trackers in them to start with unless the owner specifically puts it in there themselves, so I see this as only good.
