Title: On the Internet Someone Knows You Are a Dog
Date/time: 4:30pm Wed Oct 7 (tea at 4pm in tea room)
Location: CS 105 (small auditorium)

Abstract:
  We have been examining the leakage of privacy on the Internet:
  how information related to individual users is aggregated as they
  browse seemingly unrelated Web sites. Thousands of Web sites across
  numerous categories, countries, and languages are studied to generate
  a "privacy footprint". I report on a longitudal study consisting of
  multiple snapshots of examination of such diffusion over five years.
  I'll talk about the technical ways by which third-party aggregators
  acquire data, the depth of user-related information acquired, the
  techniques for protecting privacy diffusion and limitations of such
  techniques. Such increasing aggregation of user-related data is  
carried
  out by a steadily decreasing number of entities: a handful are able  
to track
  users' movement across almost all of the popular web sites.  
Virtually all
  the protection techniques have significant limitations highlighting  
the
  seriousness of the problem and the need for alternate solutions.

  I will also talk about a recent discovery of large-scale leakage of
  personally identifiable information (PII) via Online Social Networks  
(OSN).
  Third-parties can link PII with user actions both within OSN sites and
  elsewhere on non-OSN sites.
