Abstract
Most of the current audio media intellectual property rights protection
schemes suffer from one essential drawback: the high quality of any
lineout-linein connection, i.e. the ability to record directly from
the "speaker" so to speak, with a surprisingly minimal distorsion.
[...]
We propose a solution in which content is distributed on regular media
(e.g. CD), but is ``play-able\" only on DMAT-enabled devices. Once this
link is satisfied the next step invloves modifying the devices to
include device-identifying fingerprinting technology in the analog
stream domain (see figure).
