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.
Having contributed in large part to the Internet’s very existence, DARPA is now setting out to make its secure networks more secure. But rather than relying upon the conventional notion of a password--a complex string of letters and numerals that an individual must remember--the agency is looking to create a “cognitive fingerprint” for individuals that constantly authenticates that person for the duration of the time he or she has access to a network.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
