The Internet of Things makes the invisible visible. That’s the IoT’s greatest feature, but also its biggest potential drawback. More sensors on more people means the IoT becomes a visible web of human connections that we can use to, say, track down a virus.
Track-and-trace programs are already being used to monitor outbreaks of COVID-19 and its spread. But because they would do so through easily enabled mass surveillance, we need to put rules in place about how to undertake any attempts to track the movements of people.
