METHOD OF PRODUCT CODE GENERATION Russian patent published in 2019 - IPC G06K5/00 

FIELD: computing; counting.

SUBSTANCE: invention relates to means for marking products and is intended to prevent and detect counterfeit goods. Code generation method includes the steps: applying an N-digit number on the product, N-digit numbers are generated based on three constantly changing parameters: GPS coordinates of the enterprise, GLONASS coordinates of the enterprise and the current time, one of them changes every second (time), and the other two (coordinates) change randomly relative to a certain average position during the entire measurement time, since they depend on the number of groups of spacecraft serving GLONASS and GPS; location of the GLONASS and GPS satellites at the time of determining the coordinates; differences in the influence of the Earth’s atmosphere in signal transmission due to different GLONASS and GPS coding systems; various principles of calculating the coordinates of the GLONASS and GPS receivers; unique error, typical for both individual GLONASS and GPS navigators, as well as clocks used to measure time.

EFFECT: technical result of the invention consists in the possibility of generating a product code using three continuously changing parameters.
