It sounds like they disabled the "advertising ID" OS feature, but there are many other ways to fingerprint a device for advertising. Maybe this will lead to real privacy reform, now that the true risks are apparent. Not to mention ICE using the same data against civilians.


On iOS you can apparently simply check the APFS filesystem creation date and that's stable and unique enough to need almost no disambiguation. And any app can do this with no entitlements


Disabling "advertising ID" on iOS makes it extremely difficult to reliably fingerprint phones. Apple doesn't allow SDKs which attempt to bypass this, so the app would have to have a first party auth of some type.


>Disabling "advertising ID" on iOS makes it extremely difficult to reliably fingerprint phones.

You got this flipped. The whole point of "fingerprinting" is to build a stable identifier that works even if a explicit identifier (IMEI or advertising ID) isn't available. And yes, there are shady SDKs that do this without facing repercussions.

Testing that on ten phones is hardly evidence. I am skeptical that the approach described would be very useful for reliable fingerprinting.

IIRC Apple also specifically prohibits exporting device signals like boot time and available disk space, so that SDK would be in violation of their rules if the description is accurate.

That article is pure AI slop.


Dude, FAANG still manage to do it, day in day out.


IIRC they actually don't and it materially reduced Meta's profit when Apple rolled out the advertiser ID system.


"Facebook says Apple iOS privacy change will result in $10 billion revenue hit this year" (2022):

See also perhaps "It’s not Meta - its APPLE who have screwed us small advertisers":

I would be even more shocked if instead of adapting, they’ve continued to lose $10b a year


Wow that number is line an order of magnitude or more than I expected it would be


Won't someone please think of the poor advertisers? /s


That may have been true initially but meta has enough information to heuristically observe unidentified users and compare their behaviors with known consumers. It only takes a few actions to uniquely identify a consumer with a high degree of confidence.


Yes, it was temporary and Meta revenue and profit at all time high (before data center buildout).


Pretty sure Meta doesn't do that on iOS devices because that'll get you banned from the App Store. They just figured out ways to not need individual fingerprinting.


Apple does not enforce the rules uniformly


> app

Do they really allow any app to be downloaded on mil phones?


Everything they do is a framework for consumer protection laws.

It now directly affects the troops and military, who they ostensibly do care about. Maybe the citizens can have a little privacy reform, as a trickle-down treat.


The US will still surveil the troops and citizens. All this does is reduce the commercial attack surface for adversaries, privacy be damned.


The "buying from advertisers" strategy was a workaround, and has yet to be properly tested in court. Hopefully we'll get that loophole closed soon. They also use it heavily for recruitment to pinpoint the most desperate youth.


maybe trickle-down privacy will be more successful than trickle-down economics. one can hope.


Trump has demonstrated repeatedly, emphatically, and publicly that he does not care about the troops, or at least certainly not injured/captured/killed ones. Or minorities. Or non-citizens fighting for the country. Or citizens with non-citizen spouses/fiancees/parents.


If they cared about the troops, they wouldn't send them on bullshit missions like whatever we're doing in Iran.


You insist on using broad brushstroke language like "masked goons". Nobody is going to listen to your lack of nuance on other topics either.


How much nuance is there really to explore in that topic if even longtime ICE agents are themselves decrying the current state of the agency, and rightfully blaming the current administration for opening the floodgates to any redneck who can read a job application

Well you're right, "goon" is a value judgement, but if someone's critical thinking extends no further than 'bad word therefore bad argument' then I'm not sure I could reach them in any case.


The precise word choices have nothing to do with it. Even in this rebuttal you're still projecting an oversimplified perspective.


I mean, they are masked, right?

And they’ve been going around beating people and in a few cases killing them, like goons, right?

Just because terms can and have been used hyperbolically doesn’t mean that the same term cannot accurately describe other situations.


broad brushstroke guess; ICE


Note: much of the privacy work is done by Israeli intelligence firms. If you think that it's "our" government, you'll be disappointed.

Just out of interest, what news sources do you follow?

I ask because those claims are made by a very small few yet debunked by every independent investigation.

And here lies the problem with having intelligent conversations with followers of popularist movements:

I asked a straightforward question and you ramble on about something else entirely. If you actually cared about your country then you’d have answered honestly.

So I won’t bother to engage with you further.


Why worry about facts and evidence when you instead have "vibes from the real world."


> All you losers hang out on HN and Reddit because its the only place you can flag and moderate away reality

Minor correction, but you forgot Wikipedia. Why flag reality when you can rewrite it and police it with bots?

Reverting change, references do not meet WP::59593 subparagraph 4.1
