ERP method is chosen to identify whether a person is lying or not. It comprises of three steps and utilizes signal P۳۰۰ as marker. For the sake of simplicity, Matlab based program is constructed to take over the processes. Eleven males whose age is between ۲۰ and ۲۷ were subject to the experiment. The gathered data were then divided into training and test data to produce several models. They were then narrowed down using SVM method based on accuracy and computation time. Despite being relatively low in accuracy, the resulting model that is used in the program proved to be able to discern all of the subjects.
