  This work describes an integrated solution to face a civil security problem
in the area of Search And Rescue (SAR) of missing people. This proposal is
based on the use of emerging technologies such as Unmanned Aerial Vehicles
(UAV), also known as drones, and the use of simulated beacons on smartphones.
In particular, in the presented tool, drones fly synchronously in a specific
area so that each drone uses on-board sensors to scan and detect any signal
emitted by Bluetooth Low Energy (BLE) beacons from smartphones of missing
people. This technique allows getting the GPS position of any detected missing
person. This work also includes some security issues related to possible
attacks focused on the perimeter and physical security.
