First question to ask yourself, are those identifications copyrightable?
Sounds like they are simply facts about the data, so probably not copyrightable. You could require a contract containing forced disclosure in order to download and use the software, but this would be very non-free and GPL incompatible.
If they were copyrightable, then they would be owned not by you, but by the person using your software to create the identifications. You could require copyright assignment for anyone who uses your software, but that would be very non-free and GPL incompatible.
