Brainwave login fails if you're tipsy… hick

摘要

GETTING drunk can make it harder to enter your password - even if your brainwaves are your login. Brainwave authentication using electroencephalogram (EEG) readings is one of many biometric measures touted as an alternative to passwords. How would it work? A computer could display a series of words on a screen and measure the user's response via an EEG headset. But while research suggests that EEG readings can authenticate someone's identity with around 94 per cent accuracy, there could be confounding factors -including whether you've had a few too many drinks.
