How Google, Apple can help assure contact tracing guards privacy

Technology behemoths Google and Apple have joined forces to create functionalities for their popular smartphone operating systems that automatically notify users of potential exposures to people with COVID-19.

In the Google-Apple announcement, the companies say their systems won’t track users’ location, that users control whether they receive exposure notifications, that only public health authorities can use the system, and that neither Google, Apple, nor other users can see a user’s identity. Both Google’s Android operating system and Apple’s iOS require users to opt in to the functionality.

My latest for the AMA. The whole shebang.
