Phase Locking Value(PLV) is an algorithm describing different signals' correlation (synchronization)

which is based on the concept of phase synchronization and its effectiveness has been verified in the field of EEG(Electro Encephalo Graphy).Aiming at the issue of extracting EEG signal's feature in the current lie detection method

this study applied PLV to the field of EEG of lie detection for the first time.We find lying cognitive mechanism with the correlation between different brain regions under lying cerebration

and use support vector machine (SVM) to execute pattern recognition between liars and honest' signal utilizing the correlation as a feature.The result of classificationaccuracy is 88.50%.Therefore

the proposed method verified that the application of PLV in lie detection is effective and it provided a new way to EEG lie detection signal.
