EEG Identification Can Steal Your Most Closely Held Secrets

Fingerprints can be stolen, iris scans spoofed, and facial recognition software fooled. It has become increasingly challenging to unassailably authenticate a person's identity, so academic teams have turned to brain waves as the next step in biometric identification. Many of these efforts seek to outdo one another, boasting how accurately and accessibly they can verify a person's identity using electroencephalograph (EEG) data. In April, for example, a team in New York achieved 100 percent accuracy at identifying individuals using a skullcap with 30 electrodes. Last week, we reported on a simple set of earbud sensors that worked with 80 percent accuracy.
