Taiwan 'electronic fence' leads wave of monitoringPupils sit in desks with yellow dividers, set up as a measure against the coronavirus disease at Dajia Elementary school in Taipei on March 13. The system monitors phone signals to alert police and local officials if those in home quarantine move away from their address or turn off their phones. Officials also call twice a day to ensure people don't avoid tracking by leaving their phones at home. Privacy concerns have limited the use of location data for anti-coronavirus efforts in countries such as the United States. Other countries, including South Korea and Israel, are using satellite-based phone tracking for so-called contact tracing to see where infected individuals might have passed Sars-CoV-2 to others.
