A research paper that looks at the legal protections and implications of using and sharing personal data as part of the Covid-19 track and tracing systems developed as an urgent response.  There are surveillance consequences of the pandemic’s aftermath as any apps: transport, education, health systems and offices are being turned into vast surveillance networks. The collective nature of big data means people are more impacted by other people’s data than by data about them. Like climate change, the threat is societal and personal.  By Martin Tisné, Luminate via the Stanford Cyber Policy Centre.
