Access your computer with thought

With a device like a headset, computer users can use their mind to make passwords whenever they use the machine.

John Chuang, an associate professor at the School of Information Technology at the University of California, Berkeley, and colleagues have created a device that can identify brain wave users. Instead of using a password with a character, the system looks like this headset uses the thought password. Neurosky Mindset , the name of the device, communicates with the computer via Bluetooth to authenticate a person's identity, Discovery reported.

Some volunteers experimented with Neurosky Mindset. The team asked them to perform 7 neural activity to measure brain waves. First, every volunteer performs three tasks: focusing on breathing activity, imagining a finger moving up or down, listening to a tone of sound, and then looking at a dot on the paper after the melody. resounded. The brain waves of each volunteer are completely different from the brain waves of others.

In the next 4 quests, volunteers can choose the type of thoughts they like to increase the level of secrecy - like imagining that they are kicking the ball, singing, swinging baseball bats, cycling. In addition, they can also think of one or several objects for 10 seconds.

By measuring the volunteer's brain waves in the following four tasks and referencing them with brain waves in the first three tasks, the team created their own passwords. Even if the volunteers think of the same tasks, the password of each person is not the same as the others.
