Google researchers warn of "merging social gra

holy_calamity writes: Researchers from Google have written a paper about how social networks can undermine privacy. The most interesting scenario they discuss is "merging social graphs" — when correlating multiple social networks makes it possible to reveal connections that a person has intentionally kept secret. For example, it may be possible to work out that a certain LinkedIn user is the same person as a MySpace user, despite their attempting to keep their profiles separate. The Google solution is to develop software that screens new data added to a social network, attempting to find out if it could be fodder to such data mining. Full paper pdf.
