Privacy: personal information, threats, and technologies

The three primary thrusts of this paper are: first, that people do not think enough about their own privacy, in particular, they may not know enough about their privacy that they can really make informed decisions about sharing information; second, that technologies exist that can mitigate some of the problems associated with information sharing; and third, that services (in addition to to technologies) might be a reasonable way to think about addressing the privacy problem.
