In this paper, we explore the use of keyboard strokes as a means to access the real-time writ-ing process of online authors, analogously to prosody in speech analysis, in the context of deception detection. We show that differences in keystroke patterns like editing maneuvers and duration of pauses can help distinguish be-tween truthful and deceptive writing. Empiri-cal results show that incorporating keystroke-based features lead to improved performance in deception detection in two different do-mains: online reviews and essays. 1
