Hi All, can anyone tell me if it's possible to tamper-proof an audio recording in such a way that it can still be played on a normal audio CD player? I'm not worried about the recording being copied, but I am worried about it being modified and want to guard against it. Its for a voice recorder project in a lawyers office where they want to be able to prove conclusively that a certain audio recording was made on a specific machine and hasn't been tampered with. I understand that it is impossible to make anything completely tamper-proof, but I would like to make it at least difficult for someone to do without some very substantial resources and skills available to them. The recording unit is a standalone PC running FreeBSD 5.4-RELEASE, and it would be nice not to have to change that. Please contact me off-list with details.
