Technical News Office – Since OpenAI’s ChatGPT hit the market, AI is becoming more advanced every day. Many large companies, including Google and Apple, have introduced their AI chatbots that can complete hours of work in minutes, but recently scientists from Lund University in Sweden created an AI tool that surprised everyone the world. In fact, scientists here have created an AI tool that can analyze the microorganisms present around you and find out the places you have recently visited. This means that this AI tool can expose you.
Don’t use GPS
With this new method published in the journal Genome Biology and Evolution, it is possible to detect whether or not a person has visited places like the beach, the train station or the park. The particularity is that no GPS is used there. Instead, the tool uses the “fingerprint” of microorganisms found in different locations, which vary from location to location. This new technology can be used in fields like forensics and epidemiology.
How does this AI tool work?
Researchers have reported that some microorganisms like bacteria, fungi and algae are different types in different locations. Special groups of microorganisms, called microbiomes, are found everywhere. In this way, from the micro-organisms present on a person’s body or clothing, it is possible to know where they have been recently. In other words, who were you walking in the park with last night? This AI tool can reveal your secrets.
How was this AI tool prepared?
The AI was built on microbial data collected from different parts of the world, including microorganisms from urban areas of 53 cities, 237 soil samples from 18 countries, and 131 marine microbiomes from 9 different bodies of water . By studying these microorganisms, the AI learned to recognize specific microbial groups from different locations. According to researcher Aron Elhaik, this model takes advantage of the changing composition of microorganisms present in the human body. Additionally, it can also detect the spread of diseases and the source of infection.
How accurate is the AI tool?
The AI tool repeatedly identified various locations with high accuracy. It correctly identified the city of origin in an urban area in 92% of cases. Additionally, this AI tool was also able to differentiate between two Hong Kong subway stations, just 564 feet apart. However, its accuracy was low at London’s older and poorly maintained stations, where it only allowed correct identification 50% of the time.
