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.
They have a specific result though, which is that fingerprints from different fingers of the same person tend to be recognizable as coming from the same person, just from their characteristics. Was that also known for a long time?
Yes, it has been know since forever. It’s not like every finger is a different being. There are three well known chemicals related to the creation of fingerprints patterns. We have sequenced the RNA responsible for determining both the timing and concentrations of these three chemicals. We know thus that people’s fingerprints all have certain commonalities that can be used to identify that two, different, fingerprints came from the same person. It has been used by police forces for at least a decade now.
If you read about Turing patterns you’ll learn more and be already way ahead of these dude’s research. They are trying to parade undergrad knowledge under the AI umbrella. Maybe if they knew a thing or two about forensics they would’ve made a better contribution to science.
