FIELD: physics, signalling.
SUBSTANCE: invention relates to identification of material resources and can be used to label electroconductive articles. The method of making and installing non-reproducible identification label on an electroconductive article includes applying an identification number, an information grid and a non-reproducible matrix, as well as combined input of the identification number and the non-reproducible matrix into a database. The non-reproducible matrix is formed in advance separately from the article on a nanofilm by random point-by-point evaporation of areas of the nanofilm to obtain perforations of different size and shape or obtaining bulging areas of the surface of different size and shape on the nanofilm during electric discharge treatment thereof, after which the nanofilm is placed on the article by pressure sintering.
EFFECT: invention enables to obtain a non-reproducible identification label on an article, which enables to apply information and prevent forgery.
