The purpose of the fingerprinting is not to identify you, as in name and address and SSN, but to track you as you go from site to site, where each site is using a common ad server, such as doubleclick.

They don't know who you are (although some cross checking might reveal your identity in some cases), but they want to know if you are the same you that they've seen before.
