Abstract

The present invention relates to a method for verifying the authenticity of an image recorded in a person identifying process and belonging to a person to be identified, the method comprising the steps of recording a sequence of consecutive individual images of the person and determining the authenticity of the recorded image if at least in two consecutive individual images of the sequence intrinsic movements are detected, i.e. movements which are carried out by the person to be identified consciously or unconsciously and without changes in his or her center of gravity.
