Privacy Enhancing Technologies: An Introduction for Technologists

Making data open and available to all helps us all understand our world
and are thus better informed to shape the policies to run it. But such openness
does come with problems – one in particular is the invasion of people’s
privacy. Detailed census information about household income helps debate
and planning for local government, but can reveal personal information that
citizens reasonably prefer to keep private. Privacy Enhancing Technologies
are tools that can finesse this problem. My colleague Katharine Jarmul is a
data scientist who is also an activist for personal privacy. Here she
introduces three of these tools that are usable now: Differential Privacy,
Distributed & Federated Analysis & Learning, and Encrypted Computation.
