An electronic security system that identifies people by monitoring the unique pattern of electrical activity within their brain is being tested by European scientists.
This novel biometric system should be difficult to forge, making it suitable for high-security applications, claim the researchers behind it. The system was developed by two companies - Starlab in Spain and Forenap in France - in cooperation with researchers at the Centre for Research and Technology Hellas, in Greece. It uses an established method for measuring activity in the brain, called electroencephalography (EEG).
EEG measurements identify the location and intensity of millisecond-long fluctuations in electrical activity in the brain via electrodes positioned around a person's scalp. This can help neuroscientists understand the function of different brain areas and may also be used to diagnose and monitor neurological conditions such as epilepsy and dementia...
