"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," NEC's Shigeki Yamagata explained.

If you're hoping to try out the in-ear tech sometime soon, you're going to have to be patient. NEC says it's working to commercialize the system during the 2018 fiscal year. As far as implementation goes, the company sees the best uses for the authentication technology to ensure security of critical infrastructure and continually verifying someone's identity during confidential calls. NEC also aims for the system to be used in navigation or voice guidance situations where the directions are only intended for one person.
