Brain waves for human biometric identification

The potential use of brain waves for human biometric identification was first announced in 2013. Experts consider that the development of such applications would greatly improve the security of existing authentication methods.

In this regard, a new research project from Spain points out to the meaning of words as a specific identifier.

A team lead by Blair Armstrong, head of the Basque Center on Cognition, Brain, and Language, has recorded the brainwaves of 45 individuals as they read through a list of 75 acronyms such as “DVD” and “FBI.” The researchers scored a 94% accuracy rating in using the brain waves of the patients to distinguish their identities.

Word meanings are often more stable and irremovable in the brain than episodic memories. For example, the meaning Americans attach to the word “dollar,” or Europeans attach to the word “euro,” doesn’t change, even if currency exchange rates do.

Long time stability of word meanings in the brain makes them good candidates for pass thoughts.

Past thoughts could become the measuring standard for biometric identification in the near future, as they reside within an individual and are very difficult to manipulate. However, this concept needs further deveolpment before becoming a form of mainstream security.
