I didn't set a cookie.

PrivacyOn my Android, Brave gave a different fingerprint both times I visited.
The site thinks both times was my first visit.
The site believes I have either a 4 core or 2 core cpu. I have an Octa-core.
Also, it shows a different display size both times.
Nearly all sites like this can do nothing without javascript turned on.
I'm curious to see how Librewolf is, but that will wait until after work.
Visited it with LibreWolf (javascript turned on). The only thing that it got right was that I am on Linux, that I have an x86 processor and that I have LaTeX fonts installed.
I refreshed the page, the data shown was the same, but the fingerprint was different.
Does it know i like watching girls lick each others vaginas?
Amazing and terrifying. Thanks for the link. I am not very technical when it comes to the web so this was eye opening.
I used to have a small Firefox extension that would stagger my key presses to muddy the waters, but it made typing impractical, so I eventually removed it.
I wonder what else I can do on my end. And most importantly, what browsers can do for all their users, technical and not, by default.
I mean "1 in 122.7 million browsers look like" mine meaning it got me down to one out of about 2% of all internet users globally. I'd say it's still pretty difficult to target anything at that many people and have it be relevant. Just knowing my location and that it's a weekend basically gets down to that many or maybe fewer people on it's own since fewer than that live in my city permanently, and adding tourists/visitors and people who work on weekends, that might be about right for how many devices are online in my city right now. And that was browsing with my less locked down browser on my phone.
Actually, looking with ironfox, though, actually reduced that to about 112m. I think part of that is that ironfox apparently still seems to enable the "do not track flag" even though it was removed from Firefox because it actually made people more easy to track and no sites who track are ethical so they are not going to obey something like that. So now it's rare and makes for a really good tracking point. Need to figure out how to remove it from ironfox I guess.
Your math is not mathing, 100/122,700,000=0.000000814995925% not 2%
Also this seems to be a vibe coded website and probably doesn't use the most advanced fingerprinting techniques. Most likely your browser is actually unique if you go to https://amiunique.org/ you might get a more accurate answer.
What it got right,
- My OS. It's in the user agent header, which I hate.
- I read the page methodically at a human reading pace.
- I am using a VPN.
What it got wrong,
- Location.
- Screen res.
- Num of CPU cores.
It's good for ppl to think about fingeprinting. So demo pages like this are good. But I'm sure the identity resolution industry is MUCH better at it. They have capabilities like TLS fingerprinting, outside the browser. For most ppl, not the privacy crowd so mcuh but normal ppl, they fingerprint resource fetches to diff geographic servers. They can run 100's of scripts on a single page from every identity broker. They employ the best data scientists, to figure out every possible way.
I'm pretty careful. More than 99.999% will ever do. Can commercial fingerprinters still ID me? IDK. But like Skywalker, I have a bad feeling about it.

The impact of this is probably greatly reduced by anti-JS measures like NoScript. Some sites probably still bundle fingerprinting code into their own scripts, but the really big players contract that out to companies whose entire purpose is data-harvesting, and that's easily defeated by denying scripts from outside domains
Today all websites that have anti bot protection using pow (proof of work) already use cookies. Which is before they "ask you if you want to agree with cookies" haha. Dammit eu rules.
ya the cookie law is outdated and short sighted, the law should instead extend to ability to consent to send any identifying information instead. (Easier to investigate and potentially punish websites that do not respect the setting)
I loaded the site and went through the stuff and it worked fine. Then I turned on my VPN, and it gave me a new ID.
Changing my VPN endpoint and refreshing the page didn’t work, it still knew who I was, but closing the window and quitting the browser before changing the VPN again gave me a third ID.
They seem to know quite a bit about my phone, but it doesn’t seem like there is much that it could differentiate it from another person with the same model of phone.
This was a fun exercise.
Are you using a browser which rotates the fingerprint like Brave?
I did a private window in Safari on iOS.
It probably is rotating the fingerprint. Have you tried it in Chrome?
It's interesting to me because while it's mostly correct in each instance I tried it (phone, desktop) it actually gets some pertinent information incorrect.
For one, it only recognized the one monitor I had the browser open on, I have four monitors, so it got the resolution correct for a single monitor, but fails to capture the others, and so technically if I opened it on a different monitor with a different resolution (I had two that have different resolutions), that aspect of the fingerprint should change.
Secondly, when I went to this link from my cell phone it registered it as me typing the link in by hand while on PC it correctly registered where the link originated from (here on lemmy). Although I was using Jerboa on Android so perhaps it can't read link origin from Jerboa (which is good).
Finally, it registers my Wayland session as X11, although I'm not sure if that's a current limitation of browsers since Wayland isn't the dominant compositor yet and perhaps hasn't been added to browser user-agent info yet.
Interesting. The only thing that really surprised me was the time zone thing. Can I hide that somehow?
I know IronFox and some other forks have a setting to change your timezone to UTC-0. But you'll have to live with remembering to convert time on most websites unless you log in and your profile sets the timezone. Not a huge deal, but it trips me up more than I'd like to admit. Especially since I avoid sites that require logins. I have heard that you can get a browser plugin to change the time locally, but you'd have to trust the plugin since it will need access to all content on all sites.
Yes, the time zone can be spoofed via browser settings or with an ad-on.
Needed to enable JS.
Honest question, do you browse without JS enabled? I suppose you could just whitelist sites that you need it for.
I'm using uMatrix. I set JS as off by default.
So yeah, more complex whitelisting.
On my computers I enable js only for the url I connect to, and then if nothing works, I start enabling it for other urls or skip using the site.
You get pretty handy with it pretty soon.
I've used ublock for like +10 years if not more
Some folks browse using Tor or other high-privacy respecting browsers, in which things like NoScript are a default.
Anyway, yeah, NoScript is still pretty popular and if I recall correctly you can whitelist and regex with it. I just use the same functionality to disable javascript that is in uBlock Origin, personally.
Though uBlock doesn't set javascript.enabled to false, only blocking any kinds of js. Meaning, the <noscript> tag (with the ever so useless error message) doesn't get triggered, which results in some sites built in a defective framework just being empty.
The <noscript> messages seem to work for me with uBO.
Wha, they do? For me, only in Dillo and the likes. But none of javascript. flags is touched, so maybe there is a extension API trigger?
Ironfox seems to do its job. Me fingerprint every time. Vanadium as well (though it does disclose more in-depth device data).
A small point but it assumes that your browser's self-declared timezone is "true" to where you live. My timezone is spoofed to UTC+0; my VPN server is in a different country; and my browser language is set to en-us. I feel like if you see a user whose settings are all of the above then you can assume that none of those three data points actually describe the user, unless they coincidentally are a US English speaker or live in UTC+0, but that'd just be them coincidentally living where anti-fingerprinting browsers report you as.
Anti-fingerprinting is a fingerprint too.
Only if too few people do it.
I know that...? I'm not sure how this relates to the comment you replied to.
they are just warning other readers who might read your comment and think "oh I should spoof timezone and language too". To those readers: don't spoof these yourself, find a browser that has fingerprint resistance on by default, like Tor or Mullvad Browser, and don't change the defaults. The goal is to blend into a crowd of users with the same fingerprint
Ah ok, sorry I read that as correcting me and got confused. But yes, you are right, it is a fingerprint, the point is to just share as much of your fingerprint as possible with other users to make it hard to differentiate you.
My comment was about how the OP website has a line that claims that the reported timezone/language is the "truth" rather than my IP address, and I was just pointing out that that wasn't the case.
"Remember me on this device"
