NEC is developing a new biometric personal identification technology that uses the resonation of sound determined by the shape of human ear cavities to distinguish individuals. The new technology instantaneously measures (within approximately one second) acoustic characteristics determined by the shape of the ear, which is unique for each person, using an earphone with a built-in microphone to collect earphone-generated sounds as they resonate within ear cavities.
