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…
This is why I use multiple web browsers for different sites and workflow :)
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.
