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 homes.

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 virus.
