YouTube video on Differential Privacy

Published on

There's this cool video on YouTube today explaining in non-technical terms how differential privacy works, and I really enjoyed it. Hopefully you will, too.


I was introduced to differential privacy at Uber while our team worked with a pair of UC Berkely grad students on a system to automatically calculate what the sensitivity of a query was and adjust amount of noise injected appropriately. Ask for a million users' data in your aggregation and your noise is negligable, even with an aggressive privacy budget. Ask for a thousand, or a hundred, or one, and you're out of luck.



There's something interesting about the idea of quantifying, both on a personal level and societal level, the jitter ranges that people are comfortable with for various personal facts, or collections of them, but I haven't spent much time thinking about how that would work.
