EFF Says Forget Cookies, Your Browser Has Fingerprints
alphadogg writes "Even without cookies, popular browsers such as Internet Explorer and Firefox give websites enough information to get a unique picture of their visitors about 94 percent of the time, according to research compiled over the past few months by the Electronic Frontier Foundation. [The Research] puts quantitative assessment on something that security gurus have known about for years, said Peter Eckersley, the EFF senior staff technologist who did the research. He found that configuration information — data on the type of browser, operating system, plugins, and even fonts installed — can be compiled by websites to create a unique portrait of most visitors. This means that most Internet users are a lot less anonymous than they believe, Eckersley said. 'Even if you turn off cookies and you use a proxy to hide your IP address, you could still be tracked,' he said."
I don't care if anyone tracks my preferences or shopping history. What I care about is; 'Is that information "Personally Identifiable"?' In other words its not that they know what I do, its do they know, specifically, who I am.
I am all for research and marketing to tune products and advertising, but they don't need to know my name or various identifiers to do it.

We have a rather annoying vandal by the name of Grawp who likes to visit often and put penis pictures up on pages that little kids like to visit, among other things.
He edits via proxies, while visiting people, open wifi spots, etc... and never figures out how we know it's him.
Shame his laptop has the same fairly unique MSIE-and-toolbars useragent string.
