Biometric Brainwaves, Your Unique Signature
European scientists are developing security systems that uniquely identify people through the pattern of electrical activity in their brain.
This latest and most unique entry into the field of biometrics was developed by researchers at the Centre for Research and Technology Hellas, Greece. It makes use of the EEG (electroencephalograph) which measures the fluctations in brain activity through electrodes placed on the scalp. It is the voltage difference between different parts of the brain that produces the traces known as EEG, the so-called brainwaves.
Each person has a unique pattern of neural pathway which determines their brain activity. This makes the EEG biometric system hard to forge and therefore desirable for use in high security systems.
