What Apple's differential privacy means for your data and the future of machine learning

But with the rollout of iOS 10, Apple will begin using differential privacy to collect and analyze user data from its keyboard, Spotlight, and Notes. Roth is a computer science professor who has quite literally written the book on differential privacy (it's titled Algorithmic Foundations of Differential Privacy) and Federighi said Roth described Apple's work on differential privacy as "groundbreaking." Differential privacy builds on the introduction of deep linking in iOS 9 to improve Spotlight search. Although iOS 10 will only use differential privacy to improve the keyboard, deep linking, and Notes, Smith points out that Apple may use the strategy in maps, voice recognition, and other features if it proves successful.
