METHOD FOR APPLICATION OF NANOMARKS ON PRODUCTS Russian patent published in 2009 - IPC G06K1/00 B82B1/00 

FIELD: technological processes.

SUBSTANCE: invention is related to the field of products marking by means of application of visually indistinguishable information on product surface and may be used for protection of products against counterfeit and duplication, also for prevention of their counterfeit in consumer market and complete identification of each product unit. In method for application of nano-mark, product surface area is prepared with high purity of processing, reference points are specified on it, including reference point of coordinates start, position of which is fixed, afterwards nano-mark is applied in the form of specified signs with nanometer level of spatial resolution, application is realised by method of scanning probing microscopy in lithographic mode of microscope operation, detection of nano-mark is carried out by method of scanning probing microscopy in metering mode of microscope operation, besides, to detect nano-mark, number of maximum scanning fields is previously specified relative to selected reference point.

EFFECT: provision of product marking without chemical modification of product surface, which makes it possible to further detect applied marking, and accordingly protect the product against counterfeit or inappropriate use.
