Drawbacks of existing methods to protect the material objects against falsification are discussed. The alternative protection method is offered which is based on creation of the hidden encoded microimages in protective holograms by means of laser micropunching. The algorithm of encoding to obtain the protective hologram with the hidden encoded image is described as well as the algorithm of registering and decoding of the hidden encoded image to identify the protective hologram. The algorithm of operation of the soft-and hardware complex for individualization and identification of protective holograms with hidden encoded image is considered.
