Information processing device for restricting operation of application by operator

The mobile device is provided with an operation restriction unit, and the operation restriction unit determines which seat of the vehicle is being operated from the captured image of the back camera. When determining that the captured image is captured by the driver's seat, the operation restriction unit restricts the operation of the process execution unit. Accordingly, in the mobile device, it is possible to prevent the mobile device from being operated in the driver's seat, which is appropriately restricted from being operated in the driver's seat in a vehicle or the like.
