Not quite sure where this question might belong, so I’ll ask it here.
I’m looking for some kind of method or algorithm to identify a CD- or DVD-ROM with a fairly high degree of a probability. I’m not trying to identify the medium, but for a was to say ‘yes, I’m sure I’ve already catalogued the contents of this CD/DVD before’ in something like 1 or 2 seconds. I imagine that someone must already have tried to develop something like that.
In short, I’m looking for something like a CDDB algorithm, but for CD and DVD-ROM instead of CD-DA, and with lower false positives.
A MD5 hash for the contents (with certain restrictions) would probably have been ideal, except that it can’t be done in 1-2 seconds.
Is there anything like this out there?
