Does anyone know of a system utility (for Windows) which, when toggled on, would return a spurious System Fonts Listing, a listing that looks like a typical virgin install or which has other limited uniqueness value, in order to interfere with browser fingerprinting attempts as described here?

The goal of this "stealth" mode would be to blend in with the herd, so to speak, so that the fingerprint would look like too many others to be of much value in tracking.

The act of disabling JavaScript/Flash/Java should stop the font check, since those are the primary methods. This can be done in any major browser. I use the Firefox NoScript addon, which allows me to selectively enable JavaScript I wish to allow to run on sites, or specify some sites as trusted. It also blocks embedded objects, such as Flash and Java, until explicitly allowed.

Thanks, Bob, but I don't really want to suffer the consequences of turning off javascript. I would prefer to "stealth" the piece of info that makes me 1 in 2,037,948 -- the installed fonts list. – mrblint Feb 26 '12 at 16:34
