Corporate websites use 'supercookies' to track people without their permission
The WSJ has reported that major websites such as MSN.com and Hulu.com have been tracking online activity using powerful new methods that are almost impossible for computer users to detect.
According to researchers at Stanford University and University of California at Berkeley, the new techniques (which are legal in the US) reach beyond the techniques of traditional cookies. Hulu and MSN have been installing files known as "supercookies," which are capable of re-creating tracking information about people even after they delete their regular cookies.
Many of the companies found to be using the new techniques say the tracking was inadvertent and they stopped it after being contacted by the researchers. If yoiu believe that, I've got some land in Florida I'd like to sell you.
