Imagine sitting down at your work keyboard, typing in your user name and starting work right away – no password needed.
That’s a vision that the Defense Advanced Research Projects Agency, part of the Defense Department, wants to turn into a reality. It will distribute research funds to develop software that determines, just by the way you type, that you are indeed the person you say you are.
Darpa’s purpose is to sponsor “revolutionary, high-payoff research” for military use. But technology developed under Darpa’s auspices – the Internet itself being only one among many achievements traceable to its initiatives- eventually tends to find its way into the civilian world.
Passwords like “6tFcVbNh-TfCvBn” meet the Defense Department’s definition of “strong,” says Richard Guidorizzi, a program manager at Darpa. “The problem is, they don’t meet human requirements,” he says. “Humans aren’t built to understand random connections of characters.”
