Biometric - Ear Noise

Scientists at the University of Southampton have developed a system that can authenticate your identity by eliciting and listening to specific sounds emitted by your ear. The concept is based on otoacoustic emissions (OAE), which are sounds emitted by the mammalian inner ear in response to an audio stimulation. Their existence was first demonstrated experimentally by David Kemp in 1978 but, since then, the noises have not found an application beyond testing for hearing defects.
