Your Thoughts Are Your Password
What if you could one day unlock your door or access your bank account by simply thinking your password? Too far out? Perhaps not. 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.
Their idea of utilizing 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 you to log in with your 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.
