From the very outset of the COVID-19 outbreak, public health officials have identified the potential of contact tracing applications to both assist in conventional contact tracing activities and to warn individuals that they may have been in close proximity to someone who tested positive for the virus. The apps have unsurprisingly proven controversial, with some doubting their effectiveness and others concerned about the broader privacy and security implications. The Government of Alberta was first off the mark with its ABTraceTogether app that launched in May 2020. Alberta Information and Privacy Commissioner Jill Clayton recently completed her review of the application with an extensive investigation into its privacy implications that included an examination of the technical details, how the app functions, the role of third parties, and access to the data by contact tracers and other officials. Commissioner Clayton joins me on the podcast to discuss her report, the positive aspects of the app implementation, and the ongoing concerns that her review uncovered.
