For the National Security Agency, the fingerprint reader on your smartphone just isn't secure enough. Lockheed Martin has confirmed to Nextgov that the intelligence outfit is testing Mandrake, an identification system that verifies who you are based on the way you swipe your finger across the screen. The technology measures not only the shape of your movements, but the acceleration and speed. It can tell whether you draw in broad, fast strokes or tend to be cautious. Lockheed doesn't know whether or not the NSA is deploying Mandrake in the field, but it wouldn't be shocking. Given that it's possible to fake fingerprints, gesture-based authentication may the best way of proving that the right person really is present.
