An interesting take on browser extensions which hope to prevent fingerprinting
With respect to native browser functionality:
Browser vendors have already invested a considerable amount of work into anti-fingerprinting. However, they usually limited themselves to measures which wouldn’t break existing websites…
And extensions:
Privacy protection extensions on the other hand aren’t showing as much concern. So they will typically do something like:
screen.width = 1280;
screen.height = 1024;
There you go, the website will now see the same display resolution for everybody, right? Well, that’s unless the website does this:
delete screen.width; delete screen.height;
And suddenly screen.width and screen.height are restored to their original values…
Actually. Everybody tries to get rid of tracking by making everyone look the same. Wouldn’t it be easier to just randomize a person to every site/session instead?
What do you mean in practice ?
All the properties that are fingerprinted (resolution, canvas output, etc) should be made as unique as possible, but different for every site a user visits. So instead of trying to make everyone have the same face, make everyone’s face change every minute.
