Abstract: A method of processing image for authenticating of image liveness is identified by detecting a fake image based on the background light conditions and determining its liveness by analyzing the properties of the lighting source. The system includes image sensor for capturing image from a scene for a flicker detecting unit to detect the presence of flicker in the image to identify inactivity and the captured image is then fed to a flicker analyzing unit to determine whether the image that is being processed is actually a live image and not just a replaced static image.
