METHOD OF FORMING AN IDENTIFICATION CODE OF AN INFORMATION-PROTECTIVE LABEL WITH A GIVEN LEVEL OF UNIQUENESS

FIELD: product identification means.SUBSTANCE: invention relates to methods for production of means of identification of articles, which can be used to protect articles from counterfeiting and copying, as well as for complete identification of trademarks. Technical result is achieved by the following sequence of actions: initial data are entered: k- quantitative value of required uniqueness coefficient of identification codes; information-protective label is coated with a code containing identification and content information; reading a label code containing identification and content information; first identification code is entered into data database; generating an n+1 identification code; converting the physical model of the identification code into a digital form; values of previously recorded digital identification codes are successively extracted from database; calculating k- uniqueness coefficient of the generated n+1 identification code with respect to n codes from the database; calculating Δkis the difference between the results of estimating kuniqueness coefficient and kis the required uniqueness coefficient; if Δk>0, code n+1 is entered into database; if Δk
