Abstract
An electronic apparatus determining whether an external device spoofs a location thereof includes a communicator, a memory, and a processor configured to receive a first beacon signal and a second beacon signal from a first external device and a second external device, respectively, through the communicator, obtain information on a first distance between the electronic apparatus and the first external device, and information on a second distance between the electronic apparatus and the second external device, based on the first beacon signal and the second beacon signal, respectively, receive information on a third distance between the first external device and the second external device from at least one of the first external device and the second external device through the communicator, and identify whether the first external device spoofs an actual location of the first external device relative to the electronic apparatus, based on the first distance, the second distance, and the third distance.
