Just been reading about the AOL scandal and the fact that someone was identified via there search terms. Was wondering if there were any cases of anyone else who had ever been identified from so called anonymous data? Given that click-stream data even in a anonymous form is probably allot more raveling as to a persons identity rather than just a string of search terms how come people don't get identified all the time? There must be tons of this data lying around surely some gets leaked or hacked once in a while how incriminating is it? I mean Thelma Arnold could of just denied it was her and no one would of been able to prove otherwise, is this the same with with click-stream data, if there is any personally identifiable information contained within the stream it's just an educated guess as to who that person is and not 100% conclusive I would assume.
