The biometric potential of transient otoacoustic emissions

A comparison of verification in the temporal and cepstrum-transformed domains of Transient Evoked Otoacoustic Emissions for biometric identification

“…For example, differences in the frequency and number of spontaneous OAEs have been previously observed between the genders (Bilger et al, 1990) and different ethnic backgrounds (Whitehead et al, 1993). This paper will extend the work of Swabey et al (2009) who devised a biometric analysis based on time-series TEOAE data, and will compare this temporal domain analysis with one in the cepstral domain.…”

“…To further test and compare the performance of the Euclidean distance algorithm within the temporal and cepstrum domains, the Transverse Adult TEOAE Corpus with its greater number of individual subjects has been used. To compare the performance of the two domains, the same protocol as used by Swabey et al (2009) has been used. This protocol builds on the work of Mansfield and Wayman (2002) who address evaluating the performance of a biometric with statistical tools where there is a lack of data.…”

An Evaluation of Otoacoustic Emissions as a Biometric

“…Furthermore, the appearance of the TEOAEs suggests a high degree of idiosyncrasy. A more comprehensive analysis to support this argument is provided by Swabey et al [12].…”

“…The sets of genuine and impostor distances generated are then quantified by fitting parametric statistical distributions. The protocol used is described in detail by Swabey et al [12] and is based upon the work of Mansfield and Wayman who address the use of statistical tools to evaluate the performance of a biometric where there is a lack of data [15]. The protocol consists of standard statistical estimation (described below) along with numerical checks to ensure their validity:…”

“…The motivation for the research is that OAEs offer potential to perform an unobtrusive biometric analysis during any process where the individual is using headphones, telephone handsets or mobile phones. This paper summarizes the early work of Swabey et al [11,12] who devised a biometric analysis based upon TEOAE data in the time domain, which is presented with new data, and includes the latest results from an expanded cohort of test subjects. In addition to the expanded early work, this paper presents an evaluation of DPOAEs for use as a biometric along with a combination of DPOAE and TEOAE results to form a multimodal analysis.…”
