A group of Australian researchers published a paper on how swipes, taps, key strokes, and handwriting on touch screen devices can be used to identify individuals. “While regular tracking tracks virtual identities such as online profiles, touch-based tracking has the potential to track and identify the actual (physical) person operating the device…it can also detect if multiple people are using the same device,” according to the paper. The U.S. Department of Defense has been exploring how it can ensure department devices are used by their proper employees, and they may turn to this, or similar technologies like hand pressure measurements, to achieve this.
