FIELD: safety.
SUBSTANCE: method of identification of material resources and the protection of identification marks made by this method against forgery. Feature of the proposed method is, that chitinous elements of insects are used as a random structural pattern, for example wings, limb elements, previously placed inside the transparent plastic, and information about these chitin elements and the reference points before being placed in the computer network database are encrypted with the help of an electronic digital signature. Another feature can be recognized, that as a reference information an information grid with a stochastic, random line pitch is used, forming this grid.
EFFECT: technical result consists in expanding the arsenal of means used to create identification marks.
