With security been a paramount step to take regarding smartphones, several techniques had been used to help users apply and bypass security measures inorder to have access to their devices, of such is fingerprint scanners in recent smartphones which are commonly used to verify the user’s identity. NEC has shown that biometric authentication goes way beyond fingerprints and has developed a new way to verify your identity with your ears.

The unique technology by NEC enables earbuds to verify your identity. The sound-capturing earbuds verifies a users identity by the way sound resonates in the ear canal.

We all have unique ear shapes, same goes for the acoustics, NEC created a way for microphone-equipped earbuds to measure the acoustics after sending out sound. When the earphone and microphone produce sounds into the users ear, the resonating sounds will determine the person (which is unique based on the user). This resonating sounds bounce against the cavities of the users ear, it is the cavity bounce response that acts as the means of identification thereby determining who you really are.

Speaking of how accurate this unique technology is, the company says the process takes about a second to take its measurements and it works with 99% accuracy.

Since the new technology does not require particular actions such as scanning a part of the body over an authentication device, it enables a natural way of conducting continuous authentication.

This innovation shouldn’t be expected anytime soon, NEC says that it’s going to commercialize this technology in the 2018 fiscal year. According to the company it sees the use of this technology “in a wide range of applications, including the prevention of identity fraud in operations related to safety and security”, NEC also aims for the system to be used in navigation or voice guidance situations where the directions are only intended for one person.
