ABSTRACT:
Reproduction means of a general-purpose computer (1) reproduces a digital content only when a device ID included in the digital content corresponds to a device ID of a device by which it is intended to reproduce the digital content. When the device ID of the general-purpose computer (1) is altered, a recovery program for recovering an original device ID is downloaded from a recovery program generation server (2), thereby the device ID is recovered. With this arrangement, it is possible to provide a communication system which is capable of recovering a device ID when, for instance, the device ID is altered on account of the reinstall of a program such as an OS or content player.
