What score does your browser(s) get?
I’ll start: I got:
one in ~25000 browsers have the same fingerprint as yours
Heh, nice try FBI
1:46157.75 using mobileSafari on iOS with NextDNS.
0 because I have scripts disabled.
Within our dataset of several hundred thousand visitors tested in the past 45 days, only one in 93387.5 browsers have the same fingerprint as yours.
Currently, we estimate that your browser has a fingerprint that conveys 16.51 bits of identifying information.
But also
Your browser has a nearly-unique fingerprint
I don’t get it
There’s a couple issues going on here. Number one is it’s unique amongst the people who go to EFFs website cover your tracks. That’s not all of the internet users. Hell that’s not even most of the internet users. It’s pretty niche community.
The bits of identifying information are the critical key here. 16 bits, 2 ^ 16… 65,000 different possibilities. Each piece of information you give, makes it a little bit easier to track you. Things like language, time zone… The more bits, the easier it is to identify you. The less bits, the more you blend into the crowd.
This is why multiple people, including myself, have talked about fingerprint.com they’re professional service, who’s targeting websites, who want to track users. So they’re incentivized to track as best as able.
Even if you’ve got a great EFF score, you should always check fingerprint.com, to see if they can track you.
Mine said -
Your browser fingerprint appears to be unique among the 184,486 tested in the past 45 days.
Don’t get it either, just stock FF on stock Android
Stock browsers give a lot of information, supported system fonts, supported system languages, time zone, canvas size, browser window size, there’s a lot of data that leaks out from the browser itself.
Install a weird game that installed a weird font into your system? Well now the entire world can uniquely identify your font combination as you.
CreepJS is much better (and scarier) at fingerprinting you than EFF. I’ve not managed to completely fool it yet but I’ve got my score down to 0% trust, meaning the fingerprint it generates is pretty useless. I suspect the only way to totally fool it (by which I mean spoof my devices) would be to turn JS off completely.
On Safari 17 every time I visit the site it claims it’s my first visit, despite a trust score of 57%. Not sure if I’m interpreting the results wrong or ITP is just doing its job.
Do you have js enabled?
Trying to figure out how to accomplish this - doesn’t even work on tor
Yea, I’m just using the browser on my phone, with Private Relay and intelligent tracking prevention on for all websites. I’ve visited it a bunch of times now and I’ve gotten it to count consecutive visits a few times, but if I just wait a little while and refresh it goes back to 1 and the fuzzy fingerprint is wildly different
iOS 17 Safari (especially with enhanced fingerprint protection on) is really good at fingerprint protection. It rotates a few data points like canvas ID so that it makes you look like a new fingerprint each time.
Fingerprint analyzers can find out lots about your fingerprint that way, but if your fingerprint keeps changing, it becomes difficult to identify you. Unique fingerprints don’t mean anything if your fingerprint keeps changing.
That’s what I was kind of thinking/hoping based on the results, but I wasn’t sure if I was understanding it right. Thanks for elaborating!
