There is a lot out there. You could just start by the wiki entry and then go down the rabbit hole from there. I already linked to browserleaks, that lets you test all the vectors in their uniqueness on your machine. The thing is, that the companies that use those technologies not wish to show their hand, you know. Those things are hidden from the public eye and until now have not leaked in whole. The ad-industry is heavily using those techniques to auction off your page views to the highest bidder. You ever noticed when you go on a website and it takes the ads a second or two to load? That is the time frame where your fingerprint was determined and connected to a profile and then is offered to the ad-services "I have a male, white, mid-30, high income, from new york, looking for past interests [a,b,c], .... " and then ad-systems bid against each other to get the spot as they betting on being able to lure you in with their offer and will bet on their chance of converting their bid into a sell of a product. That all has nothing do to with just an IP. This goes waaay beyond that. Just google for this topic or "Fingerprint Analysis" in detail and you can find a lot of stuff. Check out the privacy boards of lemmy to find out more and how to protect yourself - if possible at all.
