FIELD: textiles, paper.

SUBSTANCE: present invention refers to labels resistant to forgery and/or falsification, and namely to random features of the labels, which are used for restricting forbidden attempts of label forgery and/or falsification. The method involves encoding of many label features by means of a private key in order to produce the bottom layer certificate in which the variety of the label features contains the coordinates of two ends of the variety of optical fibre strands on the label. The bottom layer certificate is decoded by means of a public key. The decoded bottom layer certificate is verified as per many features of the label for determining the label authenticity. At that, verification includes obtaining of at least two label photos, data extraction from label photos, determination of conversion function of the extracted data movement and forming multi-dimensional map for distributing the variety of the label features.

EFFECT: high degree of label protection against being copied and forged.
