----------------------------------
Everyone wants privacy - the ability to control the release and
dissemination of one's personal data. This talk will discuss why
privacy has been so difficult to deal with technically. My argument is
that it is one of the great challenges in Human-Computer Interaction,
and its difficulty results from inherent technical limitations. I will
discuss this in terms of the MIT/W3C Platform for Privacy Preferences
Project (P3P), discuss the issues in P3P, and then show why privacy in
pervasive environments will be even more difficult.
