Did you find any realistic way person can prevent being fingerprint? most idea i have seen, like a tor browsing, is focusing on changing fingerprint and not so much on making fingerprint non-unique. But it always are easy for to connect change fingerprint to former fingerprint, so what we are really need is blending in with same fingerprint as other persons.

I don't know how it can be fully prevented other than disabling javascript, but in my opinion firefox with "privacy.resistFingerprinting" is a good start, though you'll still stand out because few people are using it.

I've seen a script that performed two canvas fingerprints - a complex, and a simpler one. The latter being so simple always returned the same value regardless of the browser, so it was there to see if you have altered the canvas value. That's why changing your fingerprint might still leave you trackable.

Not sure if I exactly understand what you're trying to say here, but the Tor Browser itself certainly focuses on making its users' fingerprints identical. At least it's the only browser I know of that passes fingerprint tests (Panopticlick and friends) with JavaScript enabled.
