Researchers are developing a security system that analyzes brain waves to determine the user’s mental state, and provide or deny access to resources based on them. A research paper titled “Brainwave authentication using emotional patterns” by Violeta Tulceanu was published to the latest issue of the International Journal of Advanced Intelligence Paradigms, and describes the use of brainwave biometrics to supplement access control systems.
Applications of a security system based on mental state could include control of access to buildings, computer resources, and bank accounts to protect those under emotional stress or the influence of narcotics from harming themselves or others. It could be used to protect military, electronic learning, and healthcare systems, according to the research.
The system is initially trained to identify the user’s emotional “fingerprint” based on electrical brainwave patterns produced in response to auditory stimulus. Once patterns are matched to emotional states they can be used to evaluate access requests.
“The true engine of motivation is our capacity to perceive pleasure and fear pain, and thus, reward and punishment,” explains Tulceanu. “Our ability to react to dangerous situations is directly related to our capacity to relate to our environment, and our sense of self-preservation.”
Tulceanu mentions depression, stress, anxiety, and substance abuse as causes of changes in brainwave patterns which could detrimentally affect an individuals decision-making, and says future research on predicting slow variations in emotional state may also enable identification of degenerative mental illness or chronic depression.
Technology currently exists to evaluate a person’s emotional state based on a facial image, such as that developed by IMRSV before it was acquired by Kairos in 2015.
