In work the way of formation of latent images intended for protection of polygraphic production against falsification is presented. The way includes introduction of the latent image in the core at rastering and revealing of the latent image with use of a digital filtration. Introduction of the latent image occurs because parts of the basic image to rastering to use of various stochastic raster structures. The developed way allows to provide protection against falsification of polygraphic production of a wide circulation, for example, packing, practically not influencing on its cost and on quality of reproduction of the original.
