To overcome password fatigue, many smartphones include facial recognition, fingerprint scans, and other biometric systems. The trouble with these easy-to-use tools, however, is that once compromised—and yes, they can be hacked—you can’t reset them. You can’t grow a new fingerprint or iris if that information is divulged.
Developing a new type of password—one that measures your brainwaves in response to a series of pictures. Like a password, it’s easy to reset; and like a biometric, it’s easy to use.
The “brain password,” which would require users to wear a headset, could have implications in banking, law enforcement, airport security, and other areas.
In this System reconfigured a virtual reality headset, reducing the number of electrodes to six. Three record brain activity, two serve as grounds, and the last acts as a reference point. Typically, these headsets have 32 to 64 electrodes.
The electrodes recording brain activity measure three areas of the organ: the intra parietal sulcus (controls declarative memory), the inferior parietal lobule (processes face recognition), and the temporo parietal junction (reading comprehension).
Researchers chose specific image types to stimulate each brain region. They used animal pictures for the intraparietal sulcus because one’s memory of a certain animal can be highly individualized
For the inferior parietal lobule, researchers relied on recognizable celebrities such as Leonardo DiCaprio. For the temporo parietal junction, they used encouraging phrases such as “aspire to inspire.”
Brain passwords were more than 95 percent effective. The performance dipped slightly, by 1 percent, on the last test. These passwords contain information gathered from only three channels in less than five seconds.
