What is Neurosecurity?
Originally used to refer to the security of neural devices, we define neurosecurity as the application of neuroscience to behavioral information security to better understand and improve users’ security behaviors. One ultimate goal of neurosecurity is to design more effective user interfaces (UIs) that can help users make informed decisions.

This TED-style presentation at USENIX Enigma 2017 summarizes the research of the BYU Neurosecurity Lab.We also have published a research agenda for using neurosecurity to study security messages. The purpose of our research agenda is to highlight the promise of using neurophysiological measures, and encourage more research in this area.
The below 10-minute video gives an overview of fMRI and how it can be used to research security and privacy behavior. The presentation was given at the Symposium on Usable Privacy and Security (SOUPS) 2015.
Overview of Neurocognitive Methods
Although neurosecurity is new to the field of information systems, there is a wide range of well-established neurocognitive methods from the field of neuroscience. We summarize below some of the most prominent methods.[3-5]
|Image||Neurocognitive Tool||Focus of Measurement||Strengths||Weaknesses|
|Eye Tracking||Eye pupil location ('gaze') and movement||Identify visual activity; clear visualization of what was viewed at any given moment||Doesn't capture peripheral vision; can't ensure gaze equates with thought or attention; artificial setting may bias behavior.|
|Skin conductance response (SCR) or electrodermal activity (EDA)||Sweat in eccrine glands of the palms or feet||Low cost; easy to use; minimal intervention on subjects||Lack of predictable measurement; habituation; still some debate on interpretation|
|Facial electromyography (fEMG)||Electrical impulses on face caused by muscle fibers||High degree of precision, widely accessible, minimally invasive||Only a small number of muscles can be measured; difficulty with interpretation; setting may bias behavior|
|Electrocardiogram (ECG or EKG)||Electrical activity on skin caused by muscles of the heart||Minimally invasive; low cost; widely accessible||Heart rate may be affected by a wide variety of factors|
|Cortisol||Level of cortisol (commonly called the stress hormone) in one’s bloodstream or saliva.||Minimally invasive; low cost||Cortisol levels peak 10–40 minutes after stressor onset|
|Mouse-cursor tracking||The cursor location and movement properties on the screen||Inexpensive; noninvasive; mass-deployable; useful in natural and non-laboratory settings; surrogate for attention; changes in movement precision correlate with emotional changes||Can’t capture attention if the mouse cursor is not moving. Can’t ensure movement equates with thought or attention.|
|Brain imaging tools|
|Functional magnetic resonance imaging (fMRI)||Blood flow changes (BOLD response) in the brain due to neural activity||Noninvasive; standard data analysis methods; spatial resolution||Artificial setting; temporal resolution (few seconds’ delay); need to be careful with correlation vs. causation|
|Positron emission tomography (PET)||Metabolic changes in the brain due to neural activity||Spatial resolution||Invasive (due to injected tracer); potentially harmful; low temporal resolution (2–3 minutes)|
|Electroencephalography (EEG)||Electrical potentials on the scalp due to neural activity||Inexpensive; tolerant of a little subject motion; directly measures electrical activity; temporal resolution in milliseconds||Spatial resolution; only sensitive to outer layers of cortex|
|Magnetoencephalography||Magnetic field changes due to neural activity||Temporal resolution in milliseconds; deeper capability than EEG||Spatial resolution|
|Transcranial magnetic stimulation (TMS)||Weak electrical current causes activity in specific parts of the brain—measure activity and function of specific connections/pathways||Noninvasive; less expensive than fMRI||Can only stimulate 2 in. deep; may induce seizure or fainting|
|Functional near-infrared spectroscopy (fNIR)||Blood flow changes (BOLD response) in the brain due to neural activity||Noninvasive; less expensive and more portable than fMRI||Can only measure cortical activity 4 cm deep|
