FIELD: information technology.
SUBSTANCE: identification combination of each identification mark is hashed and the results are sent to the manufacturer. The manufacturer hashes the product design information and sends the results to an identification point. A new code combination is formed, which characterises binding of the product to at least one identification mark. Said code combination is hashed and the results are sent to the identification point. If the identification combination read by the consumer coincides with an identification combination in the data base of the identification point, the identification combination is sent to the product manufacturer where the obtained identification combination is hashed. If there is coincidence after comparing with the result of hashing the identification combination of a mark, earlier stored in the data base of the manufacturer, the said code combination is sent to the identification point, hashed again and the result is compared with the result of hashing the code combination of the binding stored in the data base. If said results coincide, the product design information and information on verification results is sent to the consumer while confirming and stating the date of verification.
EFFECT: high degree of protecting the product.
