Séminaire SAMOVAR

Connections and synergies between syntactic privacy models and differential privacy

présenté par : Josep Domingo-Ferrer

19 novembre 2013 à 15h30 salle A003 à TELECOM Sudparis à Evry


There are two main families of privacy models when
anonymizing data : syntactic models and differential-privacy
related models. Among the former, k-anonymity and its extensions
l-diversity and t-closeness stand out.

Syntactic models
tend to offer more data utility than differential privacy
but their privacy guarantees are less strict.

Contrary to a line of thought that labels syntactic
models as "the past" and differential privacy as "the future",
in this talk we will highlight several synergies between
both families of models.

Specifically, we will show that
the utility of differential privacy can be improved
via microaggregation-based k-anonymity. Also,
we will show that differential
privacy can be achieved via t-closeness and conversely.
