Brain scans might replace passwords one day

Biometric authentication is seen by many to be the natural successor to passwords, but nobody has been able to figure out which method is the best. Fingerprint scanning is the most-popular option at the moment, with retina scanning coming in at a distant second, but some researchers from Binghamton University are working on a method that’s about as futuristic as they come: brain scans. They’ve developed a system known as Brainprint, which uses an electroencephalogram cap to scan their brains while they view 500 images in succession. According to the researchers, the system has a 100% accuracy rate so far, but obviously they’re going to need to refine the process significantly before it sees any serious adoption.
