PURPOSE: A portable lie detector is provided to remove a sense of incongruity while miniaturizing by measuring a bio-signal through a small PPG sensor. CONSTITUTION: A portable lie detector includes a sensor unit(110), a signal processing unit(120), and a lie signal generator(130). The sensor unit comprises a skin reflection sensor(111) and a PPG sensor(112). The signal processing unit comprises a signal processing circuit(140), a calculation module(150), a storage(160), and a determination unit(170). Pulse, respiration, electricity reflection from the skin, and a blood pressure signal are measured through a bio-signal.
