Scientists
have developed a system that can identify the people using
their brain waves or 'brain print' with 100% accuracy , an
advance that may be useful in high security applications .
Researchers at Binghamton University in the in the US recorded brain activity of 50 people wearing a electro-encephalogram(EEG) headset while they looked at a series of 500 images designed specifically to elicit unique responses from person to person -for example a slice of pizza ,a boat,or the word "conundrum"
They found that participants' brains react differently to each image, that a computer system was able to identify each volunteer's 'brain print' 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 Laszo.
According to Laszo brain bio metrics are appealing because they are cancellable and can not be stolen by malicious means the way a finger print or retina can.The results suggest that brain waves could be used by security system to verify a person's identity.
"If someone's finger print is stolen, that person can't just grow a new finger to replace the compromised finger prints .In the unlikely event that attackers were actually able to steal a brain print , the authorized user could then 'reset' their brain prints,"Laszlo said.
