Abstract: Differential privacy is a statistical privacy technique that injects carefully calibrated noise into datasets or computations in order to bound the maximum amount an attacker can learn about any data subjects. Since first introduction in 2006, differential privacy has rapidly become the go-to tool in statistical privacy and has been deployed across industry and government. Unfortunately, many of these deployments have been plagued by controversy and confusion—not because of technical failures, but because of the human-computer interaction challenges that theoreticians did not foresee. In this talk, we draw on a number of our recent results to illustrate some of the challenges of using differential privacy responsibly, and some promising techniques we have developed to try and overcome these challenges.
