Cyber security experts warn that criminals will start using thermal detection cameras to crack passwords and PIN numbers.
Fingertips leave heat marks on recently used keypads, and AI could potentially help hackers determine which keys have been pressed.
Researchers at the University of Glasgow used thermal imaging to create a tool called “ThermoSecure,” which was able to accurately identify PIN numbers up to a minute after using a keyboard.
The researchers found that those who typed slowly were more prone to cheating, as they typically pressed each key longer.
The system cracked 86 percent of passwords when thermal images were captured within 20 seconds and 76 percent after 30 seconds had elapsed. Success rates dropped to 62 percent when 60 seconds elapsed.
The researchers also said that the system was able to hack long 16-character passwords with a success rate of about 67 percent when presented with a thermal image within 20 seconds. 12-character passwords were recognized correctly 82 percent of the time. Six-digit passwords were cracked in 100 attempts.
Mohamed Khamis, from the University of Glasgow’s School of Computing Science, said that as thermal imaging cameras become more affordable than ever and machine learning becomes more accessible, it is “likely that people will develop similar systems to steal passwords”.
