Unfortunately some of the stuff that allows fingerprinting falls into a convenience vs privacy argument. It allows a website / web app to make changes to display things more appropriately, or have helpful functionality. That's why when you use a browser that is very strict about fingerprinting, some stuff will break.

An even simpler example is the screen aspect ratio. On a small screen, you want to use as much of the space as you can, but that information can be used for fingerprinting. This was annoying on browsers like mullvad, before they updated the aspect ratio to something more modern.

That doesn't excuse companies that abuse that data for malicious fingerprinting.

I'd rather have less interactive (or whathaveyou) websites than the fingerprinting. The trade wasn't worth it.

Most of this stuff is done locally by the browser using media queries in CSS. There is no reason for that data to make its way to the server.

Greed. Lack of ethics.

Many years ago. I think it was like 2016-17 ish. I interviewed at a university for a grad program that's basically "psychology -engineering". Designing things to work with human psychology. Aka human factors psychology

(I ended up doing a different degree).

During this interview thing. I was there 2 days. It's like an event. You meet professors and tour labs. See what other grads are working on and you have lunch and dinner with current grads and professors.

So a professor was talking about developing tech to do eye tracking on phones. So they could see what you were looking at on the screen and for how long.

Now at this time I knew a little bit about eye tracking methods. Firstly I pointed out that it would be impossible for it to be very accurate without stabilizing the head (as is done in research), usually with a chin mount that holds the head still. But the guy said it didn't need to be that accurate as the intent was marketing. See what items people look at when scrolling on shopping apps/sites. And see how long they look at it.

I also pointed out that this was highly unethical because it's using physiological data to manipulate someone into spending money. Indiscriminately.

I said What about people with a shopping addiction.? Or kids using their parents credit cards. And you would be using this data to psychologically manipulate people for purchases but the data could be used in all sorts of other ways that really even more unethical.

The idea was that if someone showed interest by looking at an item longer then that item would be presented again by the app. Multiple times even. To encourage purchase.

Or to show items that were similar to try to seal the deal with what the person was finding appealing.

Possibly with price alterations to encourage purchase.

When I said again that this was obviously unethical. As a scientist our goal should not be to manipulate the public I was told "someone's going to do it, it might as well be us so we get paid for it".

I was very surprised that this came with chuckles and agreement from other students.

Another professor I talked to about her work was investigating devices that could help people drive who were hearing impaired. So it was quite the contrast.

I did not get offered a PhD position but they did offer me admission to their masters program that was 50k a year. Near D.C. 2 year program. (Combo positiond are typically "free" in a manner of speaking. Highly competitive but that's how it's done). I wasn't interested in paying them 200k for a master's (after taking loans for living expenses too).

I also learned later they don't even have masters/PhD program combos. Which is what it said on their website and I specifically applied to that. They also gave me a 2 week notice for the interview.

You ever buy a plane ticket 2 weeks ahead? $$$$$

They didn't reimburse me for that either. Which is customary for these interview invites. Typically travel and lodging is covered by the university. They had me stay in some graduates house. They had like 6 roommates.

Cheap-ass, greedy, no ethics, bastards.

Well at least I am pretty sure corruption in academia never had any long-term consequences for the population! /s

What you describe is being used by now. The permanent eye-tracking got low-level support on Snapdragon SoCs by 2023 (Snapdragon 8 Gen 3, "Sensing Hub"), the Honor Magic 6 phone advertised itself as able to "open apps by looking at them"; those desperate fucks really tried to sell this as a good thing to users. Though even this article eventually spilled the beans:

"Content Personalization: Adapt news feeds based on the focus and duration of your gaze."

They want you to think this is a good thing, but it's clearly dystopian. And already 3 years old, so by now they certainly found even more ways to make everyone miserable & manipulated.

The Google Assistant famously still listened to the microphone and uploaded data even if you tried to stop it, so I genuinely always recommend everyone to either flash your phone with GrapheneOS, CalyxOS, /e/OS or iodéOS immediately or throw it away. Modern mainline phones are a health hazard.

We once ran a trial at work for a lead generation software.

It could show who visited your website, what company they worked for, how to contact them, their socials and even a video of exactly where they pointed and clicked their mouse.

No sign up required, all by fingerprinting.

Shit was creepy as fuck, glad we don't use it anymore.

It also made me realize fingerprinting is almost impossible to avoid. There's so many little things gathered to identify you, it seems unavoidable to be traced.

[–] siravious@lemmy.world 21 points 1 week ago (1 children)

Yep, and add the OS itself spying with an unremovable universal ID, by a company who proactively reports on you, and wtf moments really turn surreal.

[–] Katana314@lemmy.world 8 points 1 week ago (2 children)

It upsets me that in working with webpages, I regularly look at “all” the network traffic going to a website - and clearly Microsoft’s GUID is hiding somewhere it won’t even show.

They didn't really develop it, it just kinda happened, because browsers send so much goddamn data to the servers

[–] perishthethought@piefed.social 8 points 1 week ago (1 children)

Sorry but, that's BS. Coders developed it. I should be punching multiple coders but someone somewhere made this happen. They could have said no.

[–] filcuk@feddit.uk 8 points 1 week ago (1 children)

No, this is BS and not how the real world works. If would be fine if you've left it as a meme. Developers (in corps) don't decide what they'll work on.

Alas, but, tragedy of commons and game theory [(and FOMO)] have us racing to the bottom (~ along with a dozen other things impeding an effective collective bargaining, or any of the other things that would otherwise allow us to have nice things).

Lots of little pieces of data about your setup. Combined together they create a combination that is extremely unique and allows companies to track you across the web.

[–] tja@sh.itjust.works 7 points 1 week ago (3 children)

Yes! You are unique among the 5376518 fingerprints in our entire dataset.

Nice

[–] boonhet@sopuli.xyz 3 points 1 week ago (1 children)

Ideally you want to be not unique though. Being unique means you're easy to track

It’s more likely that a scientist invented it than an average coder.

[–] perishthethought@piefed.social 3 points 1 week ago (1 children)

As a coder myself, I can say: we as a group need to learn to say no more often.

You're fired. We'll just hire someone from India for $0.03 a week.

We can dream about getting billions of people to all agree to stop undercutting each other. It's a nice dream
