"How can we build the registry concept out into an interactive interface so that it's usable…if you are contributing your personal data for #modeltraining for analysis, wouldn't it be great to be able…to see how your data has been protected?'
Differential privacy is a mathematically formulated definition of #privacy…the process of constructing a post-analysis dataset such that individual information cannot be extracted from it, either unintentionally or otherwise.

Who is using differential privacy? A new registry aims to make it visible
When Apple discovers trending popular emojis, or when Google reports traffic at a busy restaurant, they're analyzing large datasets made up of individual people. Those people's personal information is systematically protected thanks in large part to research by Harvard computer scientists. Now, after two decades of work on the cryptography-adjacent mathematical framework known as differential privacy, researchers in the John A. Paulson School of Engineering and Applied Sciences have reached a key milestone in moving privacy best practices from academia into real-world applications.
