There is no fool rpoof way to detect the origions of the disc. The current method is by reading the ATIP lead in, and comparing it to ATIP lead in databases available on the web, and from different software (inlcuding LiteON's SmartBurn, Plextor's Plextools, Nero CD Speed, and others). The problem with this is, too many discs use the same AYIP lead in numbers!!
A new system is currently being worked on by some. It involves reading both the ATIP lead in AND the ATIP lead out of a discs, and results in much more accurate identification, but at this time, no software or open databases currently support this method (to my knowledge).
Most of my info comes from my own personal database (which I don't share at this time, sorry) and from cross referencing several other databases, including software and web based. I hope this helps! :)
