From "Law and Order" to "CSI," not to mention real life, investigators have used fingerprints as the gold standard for linking criminals to a crime. But if a perpetrator leaves prints from different fingers in two different crime scenes, these scenes are very difficult to link, and the trace can go cold.
Congratulations to AI researchers for figuring something we knew pretty much since the first proposal of fingerprinting as a bio ID tech. We know that fingerprints aren’t unique. That’s why they’re being rejected everywhere. They don’t know what they’re talking about and refuse to work out how their research fits into established forensics knowledge. They have no prior knowledge about forensics and insist on overturning decades of forensic knowledge with “I don’t know, something with the curvatures of the lines inside the fingerprints, I guess. We don’t actually know what the AI model is doing.”
