It would be nice to hammer a manually created fingerprint into the browser and share that fingerprint around. When everyone has the same fingerprint, no one can be uniquely identified. Could we make such a thing possible?
No it isn’t.
And this is really important. If you go on Google tracked websites without tor, Google will still know it’s you when you use tor, even if you’ve cleared all your cookies.
Tor means people don’t know your IP address. It doesn’t protect against other channels of privacy attack.
Yes, it is… Tor prevents against fingerprinting as well. It isn’t just relay plumbing to protect your IP… This can easily be tested on any fingerprinting site with default config of Tor demonstrating a low entropy https://blog.torproject.org/browser-fingerprinting-introduction-and-challenges-ahead/
Not really. The “fingerprint” is not one thing, it’s many, e.g. what fonts are installed, what extensions are used, screen size, results of drawing on a canvas, etc… Most of this stuff is also in some way related to the regular operation of a website, so many of these can’t be blocked.
You could maybe spoof all these things, but some websites may stop behaving correctly.
I get that some things like screen resolution and basic stuff is needed, however most websites don’t need to know how many ram I have, or which CPU I use and so on. I would wish for an opt-in on this topics: So only make the bare minimum available and ask the user, when more is needed. For example playing games in the browser, for that case it could be useful to know how much ram is available, however for most other things it is not.
