Many governments are looking at Singapore where apps are playing a crucial role in finding contacts who may have been infected. This enables infected people to be isolated early, before they potentially infect many others.

Numerous initiatives have already sprung up to develop apps to anonymously track who you have been in contact with.

Apple and Google have a lot of experience with keeping sensitive data secure, likely far more experience than many individual developers or even governments have. We would even go so far as to highly recommend both Google and Apple make this an open-source project.

The question is: Will Tim Cook & Sundar Pichai get this done?

First of all, no, they can’t. And secondly, would you want them to by this method?
