In Spectre how does the DNA match work?
So I have seen Spectre twice now and I'm confused about one thing.
When 007 gives Q the ring he puts it on his magical scanner thingie and his laptop eventually pops up with "DNA Match" (or something along those lines). The program he is running then promptly puts it into a nice graphic with the faces of all the villains with lines connected the baddies to each other (Also inside an octopus shape... lol).
My question is how is the DNA found on the ring meant to match the 8-ish bad guys? My current running theory is that maybe the ink in the ring matched some rare octopus or something. Did I miss an explanation for this in the movie?

This issue was dealt with in a podcast interview between Empire Magazine and the film's Director, Sam Mendez:
To quote from Reddit
One of the biggest plot holes, the SPECTRE ring identifying previously encountered SPECTRE members is explained: Q's analysis (if you freeze frame it) is supposed to indicate the ring is made of iridium, which is an extremely rare element known for having high density and resistance to corrosion. Toxicology from the shown members was to indicate traces of this element discovered in autopsy, which is how Q links it together. Apparently Mendes left out the exposition on this scene because outside of the members, it's basically telling you information you already know: That Obenhauser is the head of SPECTRE.

Its been a few days since I've seen it, by my impression was that it wasn't a DNA match, it was a fingerprint match.
When he put the ring on the magical scanner thingie it uses some magical super-high-tech cameras to take high res scans of the ring and pick out the fingerprints (which actually sort of already exists). From that point, its just a matter of matching fingerprints in a database, plus some silly Hollywood style illogical UIs and you get the scene!
