Presentation
Quantifying privacy: challenges, pitfalls, and ways forward


Many privacy metrics have been proposed in the last two decades to measure how much privacy users would enjoy if different privacy protections were built into modern technologies.
In this talk, I will explore what makes it difficult to measure privacy and analyze whether existing privacy metrics are good at measuring privacy accurately and consistently (not all of them are). I will then show how metrics suites – weighted combinations of different privacy metrics – can make privacy measurement stronger and more consistent.
Finally, I will discuss how measuring user privacy on the web is different from measuring the privacy gain offered by privacy protections. As an example, I will show the research methods and metrics that can be used to measure how much privacy is promised to users in privacy policies.
