Safe Blues: A Method for Estimation and Control in the Fight Against COVID-19
How do fine modifications to social distancing measures really affect COVID-19 spread? At the moment, we don't know! In an imaginary world, we would develop a harmless biological virus that spreads just like COVID-19 but is traceable via cheap and reliable diagnosis. Then by spreading such an imaginary virus throughout the population, the spread of COVID-19 could be estimated because the benign virus would respond to population behaviour and social distancing measures in a similar manner to COVID-19. However, such a benign biological virus does not exist. Instead, we developed a safe and privacy-preserving digital alternative. We call this framework Safe Blues.
