A key issue addressed by Face Au Virus is how to leverage mobility data in the modeling of the outbreak dynamics. To complement the health data provided by public authorities, the Initiative gathers additional data, provided by private companies (including Facebook and Roofstreet), which enable the monitoring of the evolution of mobility according to its various characteristics.
Face Au Virus pays great attention to ensure that the use of data is carried out with respect for fundamental rights and freedoms and in no way aims to identify individual behavior. The initiative does not collect any personal data and only processes statistical summaries of mobility data.
