information system called Intelligent Electronic Fences System (IEFS)
(4). If GPS information is not available, based on an individual’s
mobile phone signals and nearby cell towers, it triangulates the
location of quarantined individuals (4). It monitors the nation’s entire
quarantined population and any potential people that they may come into
contact with. It tracks them in real time and retrospectively for up to
a month (4). Taiwan is tracking 55,000 People under home quarantine in
real time (5).</div><div>Complete prevention by isolating all at-risk people plays a key role in
