AI Overturns Centuries of Forensic Fingerprinting Practice?
Published in Science... Advances
Probably a fair bit to sneer at in the actual study that I'm missing, and the article I first found it in is peak AI Hype. (Big Forensics is trying to keep you from knowing the Truth as found by an undergrad with a GPU) But the part that I found most concerning is that even the whole paper doesn't appear to break down their 77% accuracy index and provide the specific result ratios that go into it. In a field where each false positive represents a step on the road to innocent people being convicted of major crimes I would really like to know that number specifically.
At a <30s glance, I'm going to guess the model is finding correlations in the artefacts of fingerprint taking, digitalisation, presentation and so on instead of fingerprints proper, like every damn time this sort of story comes up.
