NYTimes: As Coronavirus Surveillance Escalates, Personal Privacy Plummets by Natasha Singer and Choe Sang-Hun:
In South Korea, government agencies are harnessing surveillance-camera footage, smartphone location data and credit card purchase records to help trace the recent movements of coronavirus patients and establish virus transmission chains.
In Lombardy, Italy, the authorities are analyzing location data transmitted by citizens’ mobile phones to determine how many people are obeying a government lockdown order and the typical distances they move every day. About 40 percent are moving around “too much,” an official recently said.
In Israel, the country’s internal security agency is poised to start using a cache of mobile phone location data — originally intended for counterterrorism operations — to try to pinpoint citizens who may have been exposed to the virus.
