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 (PDF). 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."
