S Korea unleashes all-out policy assault on virus - ‘Big Brother’ on steroids (Asiantimes)
The Korea Center for Disease Control and Prevention is in charge of the new digital surveillance system. It combines information from 27 public and private organizations including the National Police Agency, the Credit Finance Association, three mobile carriers and 22 credit card firms. This vast collection of big data is amassed, trawled through and analyzed by AI. The system is a comprehensive upgrade to a previous program under which “data detectives” combined CCTV footage, GPS location information, credit card payments and other metrics to track down persons who may have been in contact with the infected person.
