A processor with a personal verification function has a mouse used by a hand to operate a terminal (personal computer or personal computer main body) and being able to output a photographic blood vessel image obtained by photographing a blood vessel image of the palm of the hand, and a verifying unit carrying out personal verification at a desired time on the basis of the photographic blood vessel image outputted from the mouse and a registration blood vessel image. The mouse has a radiating unit radiating near-infrared light toward the palm of the hand, and a photographing unit photographing the photographic blood vessel image with reflected light from the palm of the hand. The processor with a personal verification function and an operating device make possible personal authentication and personal identification at any time, and are operable within a saved-space without placing a burden on the user.
