Researchers create headset with biometric reader

Researchers at Buffalo University in New York are working on a curious way to protect a smartphone. They are creating a headset capable of biometrically reading the user's ear canal before unlocking a smartphone. Most surprisingly, the prototype has had 95% efficacy so far.

Like the design of each single ear canal, it means that the research is quite promising and only needs to be improved. According to Zhanpeng Jin, the chief designer, the researchers saw so many students circling with earbuds in their ears that they began to wonder what kind of innovation they could do involving the gadget.

Only 1% of Americans find mobile phone input really important

Jin PhD is a professor in the Computer Science and Engineering Department at the university and leads the research entitled EarEcho. The headset model used for the studies connects with the smartphone via Bluetooth and has recently gained prominence in a scientific publication by the Association of Computer Machines, highlighting its high effectiveness.

The University has filed a provisional patent for the technology developed and revealed how the device works. When a sound travels in someone's ear, reflected and absorbed through the channel and all people produce a single signal which can be recorded by a small microphone built into the unit.

"No matter what the sound, everyone's ears are different and we can show it in the audio recordings. This uniqueness can lead to a new way of confirming the identity of the user, fingerprint equivalent."Zhanpeng Jin, professor and researcher at Buffalo University

The reading information passed to the smartphone via Bluetooth is analyzed, if it matches the one recorded on the mobile phone, the device unlocks. The gadget has been tested in different environments such as streets and malls. To be more precise, it has also been tested with the testers' heads in different positions and angles, sitting with them, and with their heads tilted.

With a response time of 1 second, EarEcho was 95% accurate, but that number increases to 97.5% when given 3 seconds to read.
