Abstract
A mobile device is disclosed. The device includes a communicator, a GPS unit for calculating location information, a memory, a display, and a processor, and the processor is configured to generate movement path information of the mobile device by performing homomorphic encryption of a plurality of pieces of location information stored in the memory, transmit the movement path information to a server apparatus through the communicator, based on operation result data obtained by operating based on the movement path information and comparison target path information being transmitted from the server apparatus, decrypt the operation result data, and output a message notifying whether a route overlaps the comparison target path information based on a decrypted result through the display. Therefore, the route overlap is rapidly and accurately confirmed without invasion of privacy.
