Abstract: A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

Abstract: A location verification system according to an embodiment of the present disclosure includes a plurality of base stations located in respective preset areas and transmitting, to an adjacent mobile communication device, location verification information obtained by signing GPS information on the base stations with a private key. It is possible to expect an effect of re-verifying a location of a mobile communication device, such as a drone or a smart car, at a destination, when the mobile communication device has moved to the destination based on GPS information.
