RANDOM TEXTURE-BASED ANTI-COUNTERFEITING METHOD, ANTI-COUNTERFEITING IDENTIFICATION SYSTEM, ANTI-COUNTERFEITING SYSTEM, AND ANTI-COUNTERFEITING PRODUCT

摘要

A random texture-based anti-counterfeiting method, comprising the steps of: 1, selecting an anti-counterfeiting marker (2) provided with randomly distributed texture elements (1); 2, acquiring a distribution image of the texture elements (1) randomly distributed on the anti-counterfeiting marker (2) and/or a feature of the distribution image to be a distribution feature, and acquiring an intrinsic feature (4) of the texture elements; step 3, attaching the anti-counterfeiting marker (2) to an anti-counterfeiting object or a package of the anti-counterfeiting object; and step 4, during an identification operation, acquiring a distribution feature to be identified (3') and an intrinsic feature (4') to be identified from texture elements (1') randomly distributed on an anti-counterfeiting marker (2') to be identified, and comparing the distribution feature to be identified (3') and the intrinsic feature (4') to be identified respectively against a stored distribution feature (3) and a stored intrinsic feature (4). The anti-counterfeiting method can effectively ensure high reliability of a random texture-based anti-counterfeiting marker. Also provided are an anti-counterfeiting identification system, anti-counterfeiting system, and anti-counterfeiting product corresponding to the anti-counterfeiting method, each providing the same advantageous technical effects.
