Car security: Bums indentify drivers
Tokyo - Put your fingerprint scanners away. Stand aside iris measurers. Buttocks are the new way to prove who you are.
A team of Japanese scientists claims their pressure sensor sheet can accurately identify an individual's backside and when placed on a driver's seat could be used as a last line of defence to stop someone else driving away your motor.
"The sheet has 360 sensors, which collect data for 39 features to recognise a person, such as pressure patterns and the dimensions of the buttocks," said Dr Shigeomi Koshimizu, who led the research.
Koshimizu, an associate professor at Tokyo-based Advanced Institute of Industrial Technology, said his device is 98% accurate and far less onerous than conventional biometrics as it requires nothing more than someone to sit naturally.
But, he added, there are still a few hurdles to clear before the technology makes it to market.
"The recognition tends to be compromised by different clothes," he said. "Sensors read different signals from a pair of trousers and a pair of jeans."
