METHOD OF COUNTERFEIT PROTECTION AND DETECTION OF VALUABLE ARTICLES IDENTITY

FIELD: physics; images processing. ^ SUBSTANCE: invention is related to methods for counterfeit protection of valuable articles and may be used for counterfeit protection of museum valuables, expensive medicines, intellectual property objects, bank notes, credit and other securities. In method passive protective facility of preset structure is formed on valuable article, material of protective facility is magnetic quasi-2D island films Co of nanosize level, and also multi-layers, in which island films Co are separated with nanosize layers SiO2, at that detected informative criteria are abnormal absorption of radiation with foresaid nanostructures, and possibility to control availability and identity of protective facility is provided by means of analysis by optical effects in process of external effect of probing electromagnet radiation of infrared optical range. ^ EFFECT: higher level of counterfeit protection reliability and protection against valuable articles copying. ^ 2 cl, 3 dwg
