Researchers have detailed how research using electroencephalography (EEG) to measure children's brain activity as they learn to read led to a discovery of a potential 'brainprint' biometric.Cognitive neuroscientist Sarah Laszlo was conducting research at Binghamton University, State University of New York, when the method was uncovered, reports the National Science Foundation.The individualized brain readings over different time points caught the attention of bioengineer Zhanpeng Jin, a colleague across SUNY Binghamton's campus.The researchers say that while brainprints could prove an important biometric, that brain readings can only be useful if they are extremely reliable.Laszlo, Jin, and their colleague, Maria V. Ruiz-Blondet, decided to explore whether they could perfect this approach by measuring brain activity in adults who were either focusing on a recurring, easily remembered, thought or looking at specific images of different foods, words, 3-D designs and celebrity faces.By analysing brain activity response to visual and thought stimuli, Laszlo said “We can identify the individual with 100 percent accuracy. When Zhanpeng first came to me with the idea, I honestly didn't think it would work. It's amazing.”
