Far out technology: Brain wave authentication?

What if you could one day unlock your door or access your bank account by simply "thinking" your password?
Researchers at Carleton University in Ottawa, Canada, are exploring the possibility of a biometric security device that will use a person's thoughts to authenticate her or his identity, Wired News reports.
Their idea of using brain-wave signatures as "pass-thoughts" is based on the premise that brain waves are unique to each individual. Even when thinking of the same thing, the brain's measurable electrical impulses vary slightly from person to person. Some researchers believe the difference might just be enough to create a system that allows someone to log in with their thoughts.
A pass-thought could be anything from a snatch of song, the memory of your last birthday or even the image of your favorite painting. A more achievable alternative might present you with predetermined pictures, music or video clips, to which you would think "yes" or "no" while the machine monitors your brain activity.
"It is known there are differences between people's brains and their signals," says Carleton researcher Julie Thorpe, who's working on the project with Anil Somayaji and Adrian Chan. "Can we observe a user-controllable signal encoding hundreds or thousands of bits of information in a repeatable fashion? That's the real question. We think it may be possible."
The system has the potential to become a new kind of biometric security tool that -- in contrast to fingerprint readers, iris scanners or facial recognition -- would allow users to change their pass codes periodically.
The research is an outgrowth of efforts to build a brain-computer interface, or BCI, by trying to extract the meaningful parts of brain-wave signals measured by an electroencephalogram, or EEG, and translate them into recognizable computer commands that allow disabled people to control and manipulate prosthetic devices. A chief challenge facing BCI technology is that brain-wave signatures are unique, so a system trained to recognize a particular user can be quite difficult for another to manipulate.
