1. A method for an individual to disrupt recognition of their facial characteristics by a facial recognition system, said method comprising the steps of: providing an object which is adapted to be worn by the individual adjacent their face; fixing at least one infrared radiation emitter to the object, where the infrared radiation emitter emits mostly infrared radiation; wearing of the object by the individual with the at least one infrared radiation emitter adjacent their face; and at least one of directing the infrared radiation from the at least one radiation emitter a) onto at least a surface portion of the face of the individual, or b) forward of the face of the individual at all times, and said directing step including the step of causing the infrared radiation from the at least one radiation emitter to be received by a camera of the facial recognition system as the face of the individual is viewed by the camera, whereby an image of the face of the individual obtained by the camera is substantially different from an image which would have been obtained were the infrared radiation from the at least one radiation emitter not directed according to the directing step, so that determination of one or more facial characteristics of the individual by the facial recognition system is disrupted.
