A vehicle (2) is prevented from being operated by a fraudulent action. A vehicle-mounted device (100) includes a control unit (110) that generates a request signal, a transmission unit (104) that sequentially transmits a request signal generated by the control unit (110) from a plurality of respective transmission antennas (102), (202), a reception unit (108) that receives a response signal to the request signal, and a storage unit (112) that stores a history of information included in a response signal received by the reception unit, and, in a case where the response signal is newly received by the reception unit (108), the control unit (110) determines whether or not a vehicle (2) is caused to perform a predetermined operation on the basis of the information included in the response signal and the history of the information included in the response signal stored in the storage unit (112).
