| abstract | PCT No. PCT/AU81/00190 Sec. 371 Date Aug. 10, 1982 Sec. 102(e) Date Aug. 10, 1982 PCT Filed Dec. 16, 1981 PCT Pub. No. WO82/02111 PCT Pub. Date Jun. 24, 1982.The invention provides for the recording of an audio message and subsequent playback thereof and includes a facility for establishing whether the playback message is an authentic reproduction of the original message. The facility is obtained by producing a first data signal indicative of the audio message and recording it together with the audio message and producing a second data signal indicative of the playback message, and comparing the first and the second data signals to establish that the playback is an authentic reproduction of the original message if parity exists between the data signals. |
