Forget cookies, even the ultrasneaky, Flash-based "super cookies." A new type of tracking may identify you far more accurately than any cookie, and you may never know it was there.
The method pulls together innocuous data about your browser, such as plug-ins, system fonts, and your operating system. Alone, they don't identify you. Together, they're a digital fingerprint.
It's like describing a person. Just saying "brown hair" won't identify anyone. But add in "5 feet, 10 inches tall," "chipped right front tooth," "size 12 shoes," and so on, and soon you have enough information to pull someone out of a crowd, even without their name, Social Security number, or any other of the usual identifiers.
