They were so preoccupied with whether or not they could, they didn’t stop to think if they should.


As someone who has frequent dental work done, this would be a nightmare to update.


what happens when you grind your teeth down every day for a year and your “key” no longer works?


Two recent papers from the US and China have suggested systems of biometric authentication based on the aural patterns created when a user grinds or collides their teeth. Both research projects use neural networks to process custom-made datasets as proof-of-concept authentication systems. The fact that the aural print created by the user must pass through and be transformed by the auditory canal before being received through an ear-worn device (a cheap earbud that can be used also for music listening, etc.), makes this approach difficult to spoof or mimic, as well as potentially very cheap to implement.


Can someone in layman’s terms tell me what’s goin on here?
