In coming years, allowing a machine to momentarily observe your mental activity may be the key to open your email account or front door. Via Dark Reading:
It sounds like something straight out of science fiction: brainwaves taking the place of passwords in the name of authentication. A new study by researchers from the U.C. Berkeley School of Information examined the brainwave signals of individuals performing specific actions to see whether they can be consistently matched to the right individual.
Participants were asked to imagine performing a repetitive motion from a sport of their choice, singing a song, watching a series of on-screen images and silently counting the objects, or choose their own thought and focus on it for 10 seconds.
To measure the subjects’ brainwaves, the team used the NeuroSky Mindset, a Bluetooth headset that records Electroencephalographic (EEG) activity. In the end, the team was able to match the brainwave signals with 99 percent accuracy.
