Yes, thank you Liam!
NCSL also held a webinar on this topic a few months ago - https://youtu.be/PAqE27VcWvs; what the Census calls disclosure avoidance<https://www.census.gov/about/policies/privacy/statistical_safeguards.html>.

3Blue1Brown<https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw> offers great content similar to Minute Physics—yay, free education!

Great related deconstruction of contact tracing here: https://youtu.be/D__UaR5MQao

I wanted to endorse this video as well. Very interesting. One application in the VC space (perhaps there are others, but this one occurs to me) might be to monitor which fields are selectively disclosed to a specific verifier (in one or multiple proving interactions), and apply the mathematics to know how close the holder is getting to being strongly identified. I was familiar with this idea already, but unaware that there were formally proven mathematics to measure it. Cool stuff!

Thanks for sharing this Liam. I'm very interested in mathematical/formal approaches to privacy guarantees. Any such content will be eagerly absorbed!

Thanks again!

A great video on differential privacy in U.S. Census statistics (made by MinutePhysics): https://www.youtube.com/watch?v=pT19VwBAqKA. 2020 is the first year the Census can guarantee mathematically robust privacy!

This is from way back in September, but thought this would be of interest to the community.
