The Pentagon's intelligence branch is developing new tech to help it track the mass movement of people around the globe and flag "anomalies." The project is called the Hidden Activity Signal and Trajectory Anomaly Characterization (HAYSTAC) program and it "aims to establish 'normal' movement models across times, locations, and populations and determine what makes an activity atypical," according to a press release from the Office of the Director of National Intelligence (DNI). HAYSTAC will be run by the DNI's Intelligence Advanced Research Projects Activity (IARPA). It's kind of like DARPA, the Pentagon's blue-sky research department, but with a focus on intelligence projects. According to the agency, the project will analyze data from internet-connected devices and "smart city" sensors using AI. "An ever-increasing amount of geospatial data is created every day," Jack Cooper, HAYSTAC's program manager, said. Cooper also mentioned privacy, or rather a lack of it. "Today you might think that privacy means going to live off the grid in the middle of nowhere," he said. "That's just not realistic in today's environment. Sensors are cheap. Everybodys got one. There's no such thing as living off the grid." In one project, [contractor] AIS simulated a cyber attack. "Devices included traditional desktop systems, laptops, tablets, and mobile platforms," the firm said. "The technology tracks users through biometric features, including keystroke biometrics, mouse movement behavior, and gait detection."
