METHOD FOR IDENTIFYING INFORMATION CARRIER Russian patent published in 2021 - IPC B42D25/21 G08B13/24 G01N27/72 

FIELD: information technology.

SUBSTANCE: invention relates to the field of identification of an information carrier made on a paper or plastic substrate, such as drawings, regulatory and technical documentation, document forms, plastic cards, passports, books and other printed products, and is aimed at preventing unauthorised reproduction or copying, moving and storage thereof. When the method is implemented, an encoding element is introduced into the information carrier, based on at least one multi-core amorphous-metal fibre with a given response to the impact from an alternating magnetic field, a sensor is installed at a preset distance from the information carrier, for contactless identification of the encoding element in the alternating magnetic field, connected to a microprocessor unit with software, assigning to the information carrier, based on the data received from the sensor, a specific type in the accepted hierarchical system wherein, depending on the type of the carrier, a set of permitted actions therewith is established, and generating a control signal to allow/prohibit performance of these actions with the information carrier.

EFFECT: invention allows identifying information carriers made on a paper or plastic substrate.
