MONEY CODE, METHOD OF ITS MANUFACTURE AND METHOD OF CONFIRMATION OF ITS GENUINENESS AND UNIQUE CHARACTERS Russian patent published in 2018 - IPC G07D7/00 

FIELD: information technology.

SUBSTANCE: according to the invention, banknote has nano- and micropowders introduced into the paper base in the size range from 50 to 1000 Nm as micronutrients, and the paper base is also provided with a two-dimensional barcode, in which by means of an electronic digital signature alphanumeric codes, a series and number of a note, coordinate grid, coordinates and size of microelements on the grid are inserted. Method of manufacturing implies that the formation of a physical label is carried out by a stochastic process on specialized nano-paper, obtained by preliminary added nanopowder to the pulp with the subsequent manufacture of sheets of nanopaper and simultaneous fixation of the arrangement of nanoparticles relative to each other, and the obtained compressed binary digital image of the physical label, brief information about the denomination of the denomination, the series and the digital code is signed with a digital signature (private key), signed image is converted into a two-dimensional bar code and printed on this bill next to the physical label. Verification method is that the examiner reads the bar code printed on the document, discloses a digital signature using a public key and learns the characteristics of the image of the physical label, and the document verification for individuality is performed by comparing the characteristics of the mark image from the scanned mark on the barcode with the existing physical label on the same bill.

EFFECT: invention relates to the identification of monetary denominations, and is intended to verify the identity of monetary denominations and the detection of counterfeits.
