Abstract

This work presents initial findings from an investigation into the
use of otoacoustic emissions (OAEs) for identifying individuals.A data set of
2009 neonate transient otoacoustic emissions was quantified for uniqueness
using the Euclidean distance separation of the power spectra. Each sample
was compared to all the others and the minimum separation recorded. The
percentage separation for 50%, 95%, and 99% of the sample set was calculated
and the distribution of the minimum separation plotted. The minimum
separation between samples was 1.84% while 99% of the samples had a separation
of 3.68%.A simple technique was able to achieve a separation of 3.68%
for 99% of the data set, indicating it is highly likely that otoacoustic emissions
are unique to an individual and of potential use as a biometric variable in an
identification system.
