The invention discloses a peripheral device, an authorization device, and a peripheral device management method and system. According to the peripheral device, the authorization device, and the peripheral device management method and system, communication between the peripheral device and the authorization device is built for fulfilling authorization and device management functions. The authorization device is independent of a host machine employing the peripheral device. Via use of the peripheral device, the authorization device, and the peripheral device management method and system, the peripheral device can be managed in short range conditions and long range conditions, independent of application environment and network environment of the host machine employing the peripheral device. Steps in a usage scenario can be reduced, dependence on usage environment can be reduced, and the peripheral device can be applied in a plug-and-manage-and-use manner anytime anywhere.
