摘要： A watermark in the form of an added message is attached to a digital recording so that a significant content of the recording is completely unchanged by the process in the sense that any reader commonly used for such recording will extract from the recording exactly what would have been extracted in the case the added message had not been attached. This is done by hiding the added message in the error correcting code (ECC) for the significant content of the recording.
