A study, funded by the UK’s Engineering and Physical Sciences Research Council, is being conducted to see if the sound given off by human ears when specific frequencies are sent to them, called otoacoustic emissions (OAE), are unique enough to be used in future biometric systems as identification verification, according to a New Scientist article.
The intention behind the potential technology would be to outfit call centers to be able to correctly validate a customer’s identity for sensitive transactions.
These systems would require very specialized equipment to operate properly, however, as standard microphones cannot pick-up the sounds. So far, the team, led by University of Southampton engineer Stephen Beeby, can say conclusively that all the different tests have proven that each person has a distinct OAE, however, they are not yet sure if they are distinguishable enough to be used for identification.
