A method of detecting whether an individual is concealing information by utilizing physiological measurements. The individual is presented with a series of stimuli over a period of time, and the response of the individual is determined by measuring the pulse in the finger of the individual to determine cardiovascular changes during the period. The measurements showing changes in pulse rate and pulse amplitude are graphically represented and analyzed. The finger pulse waveform line length is measured, and the response of the individual analyzed by analyzing the line length to determine whether the individual is concealing information. |
