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.
- na85 6y agoPalantir? How would you defend against that profiling tech?
- saagarjha 6y agoHow does it work?
- from 6y agoNot the original commenter but my guess is that it is some kind of fine-grained CPU fingerprinting. Something like: http://s3.eurecom.fr/docs/ccs18_iskander.pdf http://s3.eurecom.fr/docs/ccs18_iskander.pdf
- spijdar 6y agoOh, 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.
