Apple recently released iOS 13.5, incorporating a new Exposure Notification API in response to the global COVID-19 pandemic. We’ve seen a few people freaking out about this, but seriously, calm down, folks. At best, the Exposure Notification API could lower contact tracing costs, reduce the spread of COVID-19, prevent life-changing health consequences, and save lives. At worst, it won’t prove particularly effective. In neither case does it pose any threat to personal privacy.
Why have Apple and Google—two companies that normally compete tooth and nail—formed this unprecedented partnership? Contact tracing is one of the key techniques employed by public health authorities in slowing the spread of COVID-19. It involves gathering information from an infected person about those they’ve been in contact with, enabling authorities to learn who might have been the source of the infection and who they may have infected. It’s a slow, laborious, and error-prone process—do you know or even remember all the people you’ve come in contact with over the past few weeks?—but it’s helpful nonetheless.
