Joe is absolutely correct. In the US, at least, there are always
legal issues. Anyone that pretends they are not around the corner
needs a heavy dose of reality.
An audit trail, by definition, must be unalterable by anyone with
access to the hardware or software. And in many countries that isn't
just who altered the data ... but who saw it as it is, for example,
under HIPAA.
