Introduction to Differential Privacy

This talk will be aimed at an audience unfamiliar with the literature on privacy preservation (as I was a few weeks ago).  The goal of the talk will be to first illustrate that whether or not the output of some interaction with real data is privacy preserving is not as simple of a concept as it may first seem, motivating the need for a precise definition of privacy preservation. Then I will give one possible definition, that of differential privacy, invented in 2006, for which the authors were awarded the Gödel Prize in 2017.
