An electronic security system that identifies people by monitoring the unique pattern of electrical activity within their brain is being tested by scientists at the Centre for Research and Technology Hellas, in Greece.

The authentication system requires a user to have EEG measurements taken beforehand. The result of each authentication test is compared with the user’s pre-recorded measurements, using signal-processing algorithms.
