If a file is saved using Microsoft word or some other type of program, you can right click on the file to find the properties, which will indicate the computer that created the file.

Is there anyway to find out who created an ISO disk image on a CD or DVD? I assume that there should be no meta data on the disk because an ISO disk image should be an exact duplicate of the original. Is my assumption correct?

To illustrate with an example, let's say you found a CD at a cafe or something. You decide to look at the CD with your computer. You find out that it is an "Ubuntu live CD" that was obviously created from an ISO file. Is there any way to find out who burned the CD? Or, on the flip side, let's say you were the one that burned the "Ubuntu live CD" and you lost it. Would somebody be able to know that it was you who made the CD? Can they get any info about the maker?
