Scientists have developed a new system that can identify people using their brain waves or 'brainprint' with 100% accuracy, an advance that may be useful in high-security applications. Researchers at Binghamton University in U.S. recorded the brain activity of 50 people wearing an electroencephalogram (EEG) headset while they looked at a series of 500 images designed specifically to elicit unique responses from person to person -- e.g., a slice of pizza, a boat, or the word "conundrum." They found that participants' brains reacted differently to each image, enough that a computer system was able to identify each volunteer's 'brainprint' with 100% accuracy. "When you take hundreds of these images, where every person is going to feel differently about each individual one, then you can be really accurate in identifying which person it was who looked at them just by their brain activity," said Assistant Professor Sarah Laszlo.
