I know you just saw me sitting on a giant turtle and now I have some pop science to share. See I am a random thinker.
What about a computer that can read your mind? I know, read further and see if you think this is as forward thinking as I do. I think the obvious purpose would be for law enforcement purposes.
The Emotiv brain-computer interface was designed to let users control their computers with their thoughts alone, opening up a new avenue for hands-free computing as well as a potential means for those with disabilities to communicate through machines. So much for good intentions. Scientists at the University of California and the University of Oxford in Geneva have devised a way to steal a user’s sensitive information–account numbers, PIN numbers, etc.–via Emotiv’s off-the-shelf brain signal-reading technology.
The $300 Emotiv device works by sensing electrical signals in the brain and interpreting them as commands for a computer. But the researchers in this case were interested in another application that essentially boils down to mind-reading. Using the Emotiv, could they tap into signals that would reveal sensitive information?
Specifically they were monitoring for the P300 signal in their test subjects, a brain signal that is associated with recognition–a tip-off that a particular word or image is meaningful to the user. The researchers placed their Emotiv-clad subjects in front of monitors displaying a series of random images of banks, numeric keypads, PIN numbers, and various people, looking for P300 signals that showed a flicker of recognition. They found that over time they could reduce the randomness of the imagery and focus in on what the user found relevant. Slowly, they were able to zero in on the images–and numbers, and banks–most relevant to the subjects.
In order to execute a fraud on someone the victim would have to be a willing participate.
