[March 20, 2020] By
TAIPEI (Reuters) - Taiwan, which has won
global praise for its effective action against the coronavirus, is
rolling out a mobile phone-based "electronic fence" that uses
location-tracking to ensure people who are quarantined stay in their
Governments around the world are combining technology and human efforts
to enforce quarantines that require people who have been exposed to the
virus to stay in their homes, but Taiwan's system is believed to be the
first to use mobile phone tracking for that purpose.
"The goal is to stop people from running around and spreading the
infection," said Jyan Hong-wei, head of Taiwan's Department of Cyber
Security, who leads efforts to work with telecom carriers to combat the
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. Jyan said authorities will contact or visit those who trigger an
alert within 15 minutes.
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. But the system has drawn
few complaints in Taiwan, which has reported only reported 108 cases of
the virus, compared with more than 80,900 in neighbouring China.
Many Asian countries are on a war footing to prevent further spread
after a surge of infections among people travelling from other
countries, especially Europe.

In Hong Kong, location-tracking wristbands are given to those put under
quarantine. In Singapore, the government uses text messages to contact people,
who must click on a link to prove they are at home.
Thailand has rolled out a mobile app that anyone arriving at an airport must
download to help monitor where they have been in the event that they test
positive for the virus. Vietnam's capital, Hanoi, this week also launched a
mobile app to help track cases, and it could be used to enforce quarantines.
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. China has used a wide range of methods
to monitor the health and whereabouts of people and enforce restrictions on
Taiwan's electronic fence has drawn some complaints for its intrusiveness.
"It's creepy that the government is teaming up with telecommunications companies
to track our phones," said a flight attendant in Taipei who was put under 14-day
quarantine after returning from Europe in mid-March.
The woman, who identified herself as Xiaomei, said she was scolded by a local
administrator after failing to pick up a check-in phone call in the morning when
she was asleep.
"They said the police will come to me if I missed another phone call," she said.
"I'm treated like a prisoner."
Quarantine violators can be fined up to T$1 million ($32,955).
