Researchers discovered that ears of each person have a unique shape and they have created a system that can scan them. The ear scanning technique uses a technology called image ray transform that highlights all the tubular structures (结构) of the ear and measures them. Professor Mark Nixon, a computer scientist who led the team from the University of Southampton, believes ear scanning could take place as passengers walk through security gates, for example, by placing cameras on either side to record an image of their ears. Comparing the results against a database of ear shapes, the new system could help airport security workers instantly identify passengers.
