continue to be a glaring weakness in digital security. And while biometric
alternatives, such as fingerprint readers, are finding their way onto more
consumer electronics devices, they are not without their limitations either. So
what about tightening the security screw further by applying a continuous
biometric — such as a keyboard that knows who’s typing on it in real-time and
could lock out an intruder based on sensing unfamiliar keystrokes?
have developed a self-cleaning, self-powered smart keyboard that can identify
computer users by the way they type. The device can help prevent unauthorized
users from gaining direct access to computers, said Zhong Lin Wang of the
Georgia Institute of Technology. It can potentially replace passwords, biometrics, and other incomplete security methods we use today to secure our computer systems.
including the pressure applied to keys and speed – that can accurately
distinguish one individual user from another. So even if someone knows your
password, he or she cannot access your computer because that person types in a
different way than you would.
also can harness the energy generated from typing to either power itself or
another small device. “The keyboard could provide an additional layer of
protection to boost the security of our computer systems,” Wang said. According
to him, password protection is one of the most common ways we control who can
log onto our computers – and see the private information we entrust to them.
as many recent high-profile stories about hacking and fraud have demonstrated,
passwords are themselves vulnerable to theft. This keyboard is a more secure
and still cost-effective and user-friendly approach to safeguarding what’s on
our computers, the authors concluded.
better than the security aspects of the keyboard are its other benefits. For
one thing, it harnesses the energy generated from typing to power itself or
other small devices. For another, it is coated with a dirt-repellent coating,
which means the keyboard cleans itself by repelling dirt and other grime. The
bad news is that, for now at least, it’s still in prototype form—but should
research continue to progress nicely, there’s every chance we could eventually
see this up for sale.
