Yep, I don’t trust this very much. Two of the same iPhones that are fully updated and in the same region should be essentially indistinguishable by the things they mentioned.
It isn't. I've worked with a company in past that has the most advanced tech available. It can uniquely identify iPhones of same model/make/year/os/safari version in the same region under the same ip address.
They promised that the tech would always give a stable and unique id from the browser. And it worked too, but it wasn't public and not for ad tech purposes.
Oh, fascinating. I've suspected this is possible for a long time, but have never seen any ideas on implementing it.
I have a POWER9 desktop, and a fair share of other users do so for privacy/security concerns, pretty hardcore Tor browser guys and the like. I've mentioned before that fingerprinting firefox on ppc64le would be very easy because of timing the non-JIT'd JS engine. I guess there's potential for much more specific fingerprinting.
