MALINTENT is technological system that was developed by the U.S. Department of Homeland Security to be implemented for detection of potential terrorist suspects.[1]
The system does various test scanning for elevated blood pressure, rapid heart and breath rate, and non-verbal cues. According to the scientists, the MALINTENT system uses a barrage of non-invasive sensors and imagers to detect and evaluate a person's facial expressions to gauge whether he or she could be planning to commit an attack or crime.
In its current development, it can recognize seven primary emotions and emotional clues and will eventually have equipment which can analyze full body movement, an eye scanner and a pheromone-reader.[2]
If the sensors pick up anything considered alarming, analysts can decide whether to subject a person to questioning.[3]
