This talk will be rescheduled:
Collections of personal and sensitive data, previously the purview of governments and statistical agencies, have become ubiquitous. The social benefits of analyzing these databases are significant: better informed policy decisions, more efficient markets, and more accurate public health data, to name a few. At the same time, releasing information from repositories of sensitive data can cause devastating damage to the privacy of individuals or organizations whose information is stored there. The challenge is to discover and release global characteristics of these databases, while protecting the privacy of individuals' records.
I will discuss a recent line of work exploring the tradeoff between these conflicting goals -- first, how the goals can be formulated precisely and second, to what extent they can both be satisfied.
The focus of the talk will be on recent results about *learning tasks* that can be carried out privately. Specifically, we show a private version of Occam's razor and also characterize the learning tasks that can be achieved in the "input perturbation" model.
This is based on several works, joint with (subsets of) Cynthia Dwork, Ranjit Ganta, Shiva Kasiviswanathan, Homin Lee, Frank McSherry, Kobbi Nissim, and Sofya Raskhodnikova.
