Differential privacy is a relatively recent topic, although it is an amalgam of well-known, and long utilized, concepts. Oddly, outside of academic circles, it was almost unknown until Apple made a big deal of it in an announcement in 2016. Differential privacy is, however, the “quantitative risk analysis” of privacy, which is why it has such important points to make to the field of privacy, and why almost nobody is using it. (Including, mostly, Apple.)
Doors open at 13:30, meeting officially begins at 14:00.
