Web site 'cookies' create
footsteps in cyberspace
Imagine shopping at a grocery store and, as you enter, you get a piece of paper with the store name and the time you arrived. Then each time you walk down an aisle, you receive another piece of paper with the name of the aisle, the date and the time. Anyone with enough interest could piece together your visit to the store, based on these bits of information.
Tourbus, a web site dedicated to examining the Internet, recently posted an article reminding 'Net surfers that cookies cannot store any personal data such as names or telephone numbers unless you actually key the information into a form at the web site sending the cookie. Web privacy may have less to do with the fact that information is stored and more to do with who has access to it and what might be done with it. Suppose you were denied a job because of a visit to a web site advocating marijuana or received a hike in your health insurance premiums because of a visit to an AIDS information site, the Tourbus article wondered.
