Usually it’s a problem when you can’t remember a password. But in this particular case, it’s by design. A new security technique mashes up cryptography with neuroscience to create passwords that are stored in users’ brains but cannot be recalled, recited, or otherwise extracted by another party.
The system is based on an idea known as implicit learning, in which the brain subconsciously learns a pattern without consciously recognizing it. In tests, Stanford University researchers put test subjects in front of a computer game in which they had to catch falling objects on the screen by pressing a key, with each key corresponding to one of six positions on the screen.
