If a system can deliver directly such risk information only
to people who need it, the damage may be possibly reduced.
This research aims at developing a system that detects people's
movement and delivers risk information. For this purpose, we
inspected the accuracy of detection of people’s movement
using geofencing, which dynamically defines geographic area
of interest. By using geofencing, it is possible to detect entries
and exits of people at the specific area. Thus our system can
deliver what is happening at a particular area directly to the
users.
