Tactile passwords could stop ATM 'shoulder-surfing'

Using tactile passwords as a UI for security ...

"Entering passwords using a Braille-like device could prevent snoopers from stealing sensitive computer codes, such as ATM numbers, researchers say.

Computer engineers at Queen's University Belfast, UK, developed the tactile security system – a mouse with a grid of 16 mechanically-controlled pins that sit beneath the first and second finger of a user's hand.

The system was originally developed for visually impaired computer users. Its designers claim the system is more secure than a conventional keyboard as it is impossible for anyone to spy on a user's keystrokes.

To use the system a user moves the mouse over a grid of nine blank squares displayed on a computer screen. Rolling over each square causes a different pattern to appear under their fingertips.

A user is given a sequence of tactons to remember and simply clicks on the squares that match their pass-pattern. The sequence of tactons and squares is randomised each time, making it impossible for anyone to spy on a user as they click."    (Continued via New Scientist Tech)    [Usability Resources]
