Not All Fingerprints Are “Unique”

The most common information about fingerprints is Even within the same person, each is unique.. This fact, beyond being just information, has been seen as a valuable resource used for many years, especially in solving crimes.

However, one of the biggest problems encountered is the finding of traces from different fingers, especially at crime scenes, and the knowledge that each finger is unique. Inability to directly link a single criminal There were situations like this. The new research reverses this situation and provides critical information that will shorten criminal detection and investigation processes in forensic medicine.

”Artificial intelligence saw what experts could not see”

The research, conducted by a group of researchers from the Computer Science and Engineering departments of Columbia University and the University of Buffalo, was initially conducted in the USA. consisting of 60 thousand fingerprints was conducted using a publicly available data set. Tens of thousands of data, including different fingers of the same person and fingers of different people, were examined with an artificial intelligence-supported system.

According to the first results obtained, the prints of different fingers of an individual were not completely unique and the developed artificial intelligence-supported system to identify which fingerprints belong to the same person started to develop gradually. As artificial intelligence is fed with more data, its success rate begins to increase and reaching ten times the efficiency of forensic science demonstrated high efficiency and success.

According to the research team, instead of focusing on the branches and end points in fingerprints that experts focus on, artificial intelligence focuses on the circular structure and shape at the center of the fingerprints. angles and curvatures of the rings was focusing. From this perspective, it was discovered that the prints taken from different fingers of the same person were quite similar to each other.

It is as important for forensic science as it is for artificial intelligence:

Another issue the team emphasizes is the active use of artificial intelligence in scientific research. The team in general a bias against artificial intelligence He states that there are many opinions that AI is just a system that “spewing out information”, but even with a simple data set and a simple artificial intelligence-supported system, many problems that have been overlooked until now can be solved.

The research team also stated that the research should be expanded and fed with much more data. many unsolved criminal cases He states that it can be solved in the light of this information and that the names of many innocent people can be cleared.

Speaking of artificial intelligence;
