This New York Times article demonstrates how easy it is to figure out who did the searching on a search engine, the one we use every days like Google, Yahoo or MSN.
But there’s a program that help us and gives us the possibility to avoid the tracking. It’s TrackMeNot:
TrackMeNot runs in Firefox as a low-priority background process that periodically issues randomized search-queries to popular search engines, e.g., AOL, Yahoo!, Google, and MSN. It hides users’ actual search trails in a cloud of indistinguishable ‘ghost’ queries, making it difficult, if not impossible, to aggregate such data into accurate or identifying user profiles. TrackMeNot integrates into the Firefox ‘Tools’ menu and includes a variety of user-configurable options.
Every twelve seconds the program picks a random pair of words from a dictionary and sends it to either AOL, Yahoo, MSN, or Google. The problem is that some search made by the program are worse than that one someone, like me, can do. The random dictionary cantains words like:
HIV, atomic, bomb, bible, bibles, bombing, bombs, boxes, choke, choked, chokes, choking, chain, crackers, empire, evil, erotics, erotices, fingers, knobs, kicking, harier, hamster, hairs, legal, letterbomb, letterbombs, mailbomb, mailbombing, mailbombs, rapes, raping, rape, raper, rapist, virgin, warez, warezes, whack, whacked, whacker, whacking, whackers, whacks, pistols
Probably a search on “erotic rape” will not make the legitimate searches less noteworthy….
But my one is only an opinion
