Future Attribute Screening Technology (FAST) Project
Project Manager: Robert Middleton

Project Overview: The Science and Technology (S&T) Directorate Human Factors/Behavioral Sciences Division (HFD) Future Attribute Screening Technology (FAST) project is an initiative to develop a prototype screening facility containing a suite of real-time, non-invasive sensor technologies to detect cues indicative of mal-intent (the intent or desire to cause harm) rapidly, reliably, and remotely. The system will measure both physiological and behavioral signals to make probabilistic assessments of mal-intent based on sensor outputs and advanced fusion algorithms and measure indicators using culturally neutral and non-invasive sensors.

Emphasis mine.
