About the Event
The problem of statistical disclosure control - revealing accurate
statistics about a population while preserving the privacy of
individuals - has a venerable history. An extensive literature spans
multiple disciplines: statistics, theoretical computer science,
security, and databases. Yet privacy breaches abound, both on paper
and in practice.
This talk describes a large body of work revisiting the problem from
the perspective of modern cryptography. We define differential
privacy, the first mathematically rigorous and comprehensive notion of
privacy tailored to private data analysis. We then present general
techniques for achieving differential privacy while simultaneously
preserving utility of the data, together with impossibility results
that guided its development.
Finally, we describe two of the exciting new directions this work has
