The NSA has developed a new technology, dubbed Mandrake, that can identify users from the way they swipe strokes and text on a smartphone screen. The news was reported by officials with Lockheed Martin who helped design the technology. Mandrake is able to remotely analyze the curve, unique speed and acceleration of a persons finger stroke across the touch screen of their smartphone. The technology could be used for emergency responders who do not have the capability to access an incident command website.”]
