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.
