The obvious answer is browser fingerprinting. You probably already knew that. I'm just mentioning the missing context of this post.

  Yeah, you can fingerprint by using fonts on canvas. The are oh so slightly differently aliased. If i recall correctly.

  Yes I do already know that.. I find it criminal that they call themselves private then take your fingerprint.. Even Google and Bing don’t do that!
