Your ear is your new password
This technology, designed by NEC corporation, promises to make the ear the new password. It involves an earbud detecting the characteristics of each ear cavity with a sound signal. An embedded microphone detects subtle variations in the signal that occur due to the unique differences in our ears. By Bluetooth, the device can be used to unlock your phone, for example.
2018, year of the ear? Biometric authentication is becoming increasingly popular and one advantage of this device is that the authentication is hand-free, so can be done while moving without requiring the wearer’s attention (unlike typing a password on your smartphone).
