Google is open-sourcing a library that it uses to glean insights from aggregate data in a privacy-preserving manner. Called Differentially Private SQL, the library leverages the idea of differential privacy (DP) — a statistical technique that makes it possible to collect and share aggregate information about users, while safeguarding individual privacy. This allows developers and organizations to build tools that can learn from aggregate user data without revealing any personally identifiable information. (Source: The Next Web)
