Interesting article about password problem solving idea based on tactile passwords appeared in NewScientist.
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.
