Abstract

Изобретение относится к защите документов от подделки. Способ включает изготовление защитной метки, содержащей трехмерный рельеф, и идентификацию ее подлинности. Рельеф метки получают путем контактного тиражирования на полимерной пленке. На рельефе метки находится отражающее покрытие, на которое наносят клеевой слой. Рельеф содержит участки, имеющие шероховатую поверхность. При идентификации подлинности участок рельефа проверяемой метки, имеющий шероховатую поверхность, освещают пучком когерентного излучения и сравнивают спекл-картины, рассеянного им излучения, со спекл-картиной излучения, рассеянного соответствующим участком подлинной метки. Хаотические неровности шероховатой поверхности имеют характерные размеры, соизмеримые с длиной волны освещающего излучения. Рельеф метки может содержать элементы, доступные визуальному наблюдению (невооруженным глазом или в оптический микроскоп) при идентификации. Технический результат заключается в повышении надежности защиты за счет исключения возможности голографического копирования метки.The invention relates to the protection of documents from counterfeiting. The method includes manufacturing a security tag containing a three-dimensional relief and identifying its authenticity. The relief of the label is obtained by contact replication on a polymer film. On the relief of the mark is a reflective coating on which the adhesive layer is applied. The relief contains areas having a rough surface. When identifying the authenticity, the site of the relief of the checked mark, having a rough surface, is illuminated with a beam of coherent radiation and the speckle pattern of the radiation scattered by it is compared with the speckle pattern of the radiation scattered by the corresponding portion of the genuine mark. The chaotic irregularities of the rough surface have characteristic dimensions commensurate with the wavelength of the illuminating radiation. The relief of the label may contain elements that are accessible to visual observation (with the naked eye or through an optical microscope) for identification. The technical result consists in increasing the reliability of protection by eliminating the possibility of holographic copying of the label.
