TITLE: Data Privacy Technologies: From Alchemy to Engineering Discipline

SPEAKER: Arvind Narayanan

ABSTRACT:
Established practices for data privacy focus on simplistic data
transformations such as the removal of “personally identifiable
information.” On the other hand, academia has produced a long line of work
on privacy-preserving computation that has yet to be translated into
practice. I envision privacy technologies as an engineering discipline
grounded in a solid understanding of what technological mechanisms can and
cannot do. In this talk I will describe my past, ongoing and planned work
towards this goal. The first part of this research program — now nearing
completion — is to demonstrate the inadequacy of the current paradigm by
developing reidentification and statistical inference algorithms for
various types of “anonymized” data: our preferences, transactions, social
relationships, and behavior. The second part is to develop an approach to
building systems based on lightweight cryptography, a hybrid of centralized
and decentralized architectures, and incorporation of policy-based
defenses. I will describe how I have applied these principles to my work on
location privacy
and behavioral ad targeting.

BIO:
Arvind Narayanan is a post-doctoral computer science researcher at Stanford
and a junior affiliate scholar at the Stanford Law School Center for
Internet and Society. He completed his Ph.D at UT Austin in 2009. Narayanan
studies information privacy and security, and moonlights in policy. His
paper on deanonymization of large datasets won the 2008 Privacy Enhancing
Technologies award and his 2011 paper on location privacy at NDSS won the
distinguished paper award.
