Use Your Brainwaves As A Password
Brainwave authentication is one of many biometric identification systems being studied as an alternative to passwords. Could you authenticate your identity with electroencephalogram (EEG) readings?
"Brainwaves can be easily manipulated by external influences such as drugs [like] opioids, caffeine, and alcohol", Chin says. "This manipulation makes it a significant challenge to verify the authenticity of the user because they drank an immense amount of alcohol or caffeinated drink."
Tommy Chin, a security researcher at cybersecurity consultancy firm Grimm, and Peter Muller, a graduate student at the Rochester Institute of Technology, decided to test this theory experimentally, by analysing people’s brainwaves before and after drinking shots of Fireball, a cinnamon-flavoured whisky.
Chin and Muller presented their findings at security conference ShmooCon in Washington DC, last weekend, with initial results from a small number of tests indicating that brainwave authentication accuracy could fall to 33 per cent in inebriated users. They recruited more participants at SchmooCon to gather more data.
So it has a way to go before it is really usable in security situations. But Philip K. Dick was quite interested in brain scans in the 1960's. In his 1965 novel The Zap Gun, he suggests that the scans of CEO's could be used to keep their office contents secure. Consider the cephalic pattern door.
