Hi Group,

Crypto seminar at MIT next Friday morning. I *really* want to go this,
but can't due to faculty retreat.  If do you go, I would appreciate if
you could explain the work to me!

Title: How to compute group statistics while preserving individual privacy
Speaker: Eleanor Rieffel,Senior Research Scientist, FXPAL

As sensors become ever more prevalent, more and more information will
be collected about each of us. A long-term research question is how
best to support beneficial uses while preserving individual privacy.
Aggregate statistics are sufficient for many beneficial uses in public
health and medical research, smart metering, and user analysis, and
other areas. W

We introduce "aggregator oblivious" protocols for time series data in
which an individual has full access to her own data, a third party
processes the data without learning anything about the data values,
and analysts learn only statistical information over the whole group
at each time step. We describe two families of non-interactive
aggregator oblivious protocols. We also show how these schemes can be
combined with differential privacy mechanisms to obtain stronger
privacy guarantees, and how encryption makes it possible to obtain a
given level of differential privacy with less noise.
