Looking for a friendly, accessible way to learn about differential privacy? 🧐 Prefer simple explanations to ugly equations? 😇
Introducing my ✨ newly revamped ✨ blog post series about differential privacy, now with an intro page & table of contents 🌈

Hahahaha I'm hearing that posts that mention other social networks by name are de-prioritized in "for you" timelines. What a loser move 🤣
Anyway I'm over there ⤵️

I now have a presence on Bluesky: bsky.app/profile/desfontain.… 🦋
If your main presence is on Bluesky, it'd be fantastic if you could follow bsky.app/profile/ap.brid.gy, so your posts are also mirrored on Mastodon, and I can follow you from there 💖

Super excited about this ✨ new blog post ✨, where I try to offer a super simple & intuitive explanation of the exponential mechanism, a fundamental building block in differential privacy 🧱
Feedback welcome! 💝

New, by me: what do we know about differential privacy composition theorems? What's missing, and would be useful to folks who are building practical DP software? 🔧
This blog post surveys existing results and raises a bunch of overlooked open problems. Feedback welcome! 💖

New blog post co-written by yours truly! In which we look at data clean rooms, what they do, what they often don't do, and why that can be a Problem™ 😬
Feedback super welcome as always! 🌈

If you're at @PET_Symposium next week, don't miss Marika Swanberg's talk about her research at @TumultLabs last summer: a novel DP mechanism for partition selection which, in contrast to prior work, scales horizontally 📈
In collaboration with Sam Haney & yours truly 😊

"When we want to protect individuals whose data is distributed across multiple rows, protecting individual rows is not enough." @TumultLabs introduces privacy IDs, .. "privacy identifiers enable the protection of individuals across large datasets, no matter how often they appear"

And now for something different: during a customer engagement, we stumbled upon a natural, but surprisingly tricky open problem in differential privacy. We couldn't figure it out, so we posted a simplified version of it as an open problem on DifferentialPrivacy.org 👀

Woo-hoo, this is a huge step for Tumult Analytics! 🤩
Privacy IDs are a super important feature, and making it work with all our other advanced features was no small feat 😊
Check out the blog post we wrote to explain what problem it solves, and how it works in practice ✨

excuse me while I earnest-post about my work for a sec!! along with @TumultLabs I helped @Wikimedia release ~250 million private pageview stats, covering ~1 *trillion* pageviews from wikipedia and other projects from 8 years of browsing activity
21 Jun 2023
Did you know that we release data about pageviews of every Wikimedia project hourly?
But we were asked to go further.
In partnership with @TumultLabs, we released today almost 8 years of pageview data divided by country, project, and page. Take a look ⬇️

It was such a privilege to work with @Wikimedia folks on this data release 💙
They care a *ton* about the privacy of Wikipedia users, and also wanted to uphold the nonprofit's commitment to transparency and open data 🔓
A perfect job for differential privacy! ✨
