Although we are currently working our way into the era of accurate voice print and eye scan verifications, text passwords remain the primary means for securing our data. Now, a new research project has come up with a device that leapfrogs all the aforementioned methods and offers possibly the most secure password of them all: a thought.
Led by John Chuang of the UC Berkeley School of Information, the team of researchers recently introduced a way to authenticate identity via electroencephalograms (EEGs). The experimental method is termed as using a "pass-thought" instead of a text password. Using the Neurosky Mindset headset, the team was able to successfully identify themselves to a computer via Bluetooth during a series of experiments.
Specifically, the experiment's subjects were asked to imagine a series of select actions, such as singing a particular song or imaging a set of objects of a particular color. These pass-thoughts enabled the participants to repeatedly identify themselves to the computer.
According to the research group, despite the futuristic sound of set-up, the use of brainwaves for password authentication could rapidly become a cheap and easy security measure in the near future. In the study group's research paper titled "I Think, Therefore I Am: Usability and Security of Authentication Using Brainwaves," they concluded, "brainwave signals, even those collected using low-cost non- intrusive EEG sensors in everyday settings, can be used to authenticate users with high degrees of accuracy."
