The present invention relates to the technical field of biometrics recognition. Disclosed in embodiments of the present invention are a liveness detection method and device, an electronic apparatus, a storage medium, and a payment system, a video monitoring system and an access control system using the liveness detection method. The liveness detection method comprises: acquiring an image of an object to undergo detection; performing critical point detection on regions in the image corresponding to biological features of the object; constructing a constraint box in the image according to detected critical points; acquiring a shape change of the constraint box constructed in the image; and if the acquired shape change of the constraint box is abnormal or no critical points have been detected, determining that the object is fake.
