Research project: OtoAcoustic Biometrics

Currently Active: 
Yes

A spin-off of interests in information processing has been development of a project on biometrics in collaboration with Steve Beeby (ECS; funded by EPSRC).

We have established that the otoacoustic emission for a persons’ ear is an individual characteristic that supplies good identification information. This could be potentially useful as a biometric ‘signature’. We have shown that a computer generated sound can induce a person’s ear to actively generate sound which has a characteristic frequency profile. We have been exploring ways in which this could be exploited to allow automatic confirmation of a person’s identity on-line.
