This vehicle-mounted device is provided with the following: a positioning unit that outputs a positioning result indicating the current location of a vehicle on the basis of a positioning signal received from an artificial satellite; a positioning-result memory unit that associates positioning results with times and stores said positioning results; and a processing unit that uses past positioning results stored in the positioning-result memory unit and the current positioning result from the positioning unit to detect spoofing on the basis of whether or not the movement of the vehicle satisfies prescribed criteria.
