Let me ass you a question: did you know your bottom has a signature like a fingerprint?
You may have answered no, butt you would be mistaken according to scientists at the Advanced Institute of Industrial Technology in Tokyo.
They have been working hard on a new vehicle security system based around backside identification technology.
With reportedly 98 per cent accuracy the researchers at AIIT reckon they can distinguish drivers – and presumably motorcycle riders -- by bum pressure.
The system measures bum force via 360 sensors in a specially built car seat, which provide pressure level aggregate data to identify a driver.
The research team now hopes to work together with companies to produce a commercial version of the technology. It is unclear how the system will react to an unauthorised bottom, but it could be unpleasant...
