Smart city solutions have proved handy for curbing the contagion, but recent experience has also shown how much they rely on public trust. And that in turn depends on transparency and robust safeguards
COVIDSafe uses Bluetooth radio waves. These can only measure how physically close two people are, but not if those people are in the same room, or even in different cars passing each other.
Only 51% of survey participants said they supported linking the number of COVIDSafe app downloads with an easing of lockdown restrictions.
From conflicts with specialised medical devices, through to unresolved problems with iPhone functionality, COVIDSafe is in need of updates. A major one may come within the next few weeks.
A critical problem with the bill is it allows the federal government to collect much more personal data from COVIDSafe users than is necessary for contact tracing.
One bespoke contact tracing device is a bluetooth 'pen' device, which can be handed in if diagnosed without relying on smartphones.
While preliminary tests indicate user data isn't being sent to the government, a publicly-available source code is needed to ensure the app's transparency.
