Seven Privacy Worries in Ubiquitous Social Computing

less than 1 minute read

Motahari et. al identify seven privacy threads:

  • Inappropriate use by administrators
  • legal obligations: e.g. police
  • inadequate security
  • design invasions (poor features): e.g. cell phone localizer
  • social inference through lack of entropie: campuswiki
  • social inference through persistent user observations
  • social leveraging of privileged data: A asks B; "additional" friends in social networks

The authors show that users are more concerened about the threads they know (1-4), than over the (even more dangerous) last three points.
