This doesn’t worry me too much, the value seems like it should be the exact same hash for any iOS Safari visitor with the same screen resolution and browser language? I’d be fingerprinted as part of a group of (probably) several hundred thousand.

It’s a shame that browsers leak things like font presence, but of course when sites can read back canvas contents without querying the user is when it all goes out the window.



Chrome (Safari) on iPhone 13 Pro Max: db9df4c8c770242aaf1e0efdd5cf8ab2

There’s likely enough info in the hash to figure out exactly what device I’m on since nothing else will have the same pixel density, screen height, and screen width: https://stackoverflow.com/questions/46313640/iphone-x-8-8-pl...

Dark mode adds on one more bit, but everything else should be the same across iOS devices. Not sure if that’s enough to track individuals among a small userbase every time their IP address changes.


I'm pretty sure the Pro Max 12 has the same screen settings. I also wonder about maximized windows on a 1080p monitor. I know DPI of desktop monitors at one point was a constant returned value.
