Diffrential Privacy with AI and the future of health tracking

One of the major reasons people are vary of jumping onto the self-tracking wagon is privacy of their data. Granted, when you're trusting a fitness tracker to record how much you've run and how your heart rate varies, you're trusting a slew of services that are working in the background. How can that balance be achieved? Now with iOS 10, Apple first introduced the concept of differential privacy. And trust Apple to come up with a solution to the whole data gathering / privacy conundrum. While the usage of data driven AI services implies that data collection is necessary, differential privacy brings an entirely new level of identity masking into play.
