An american company developed a biometric system to identify the user with the way he uses the keyboard and mouse on his computer.
The main and first use of this software is to identify government workers in the United States when using their computers. They will remove all passwords and replace them with a completely automated system.
How does it work? The system measures the cadence when typing on the keyboard, the rhythm and speed when moving the mouse and even the language used when writing e-mails. The first tests showed 99% user identification accuracy.
