Title:
MICRO-TEXTURE ANTI-COUNTERFEIT METHOD
Document Type and Number:
WIPO Patent Application WO/2016/177301
Kind Code:
A1
Abstract:
A micro-texture anti-counterfeit method comprises the following steps: a) printing a coding (4) identifier or image-text (5) identifier having random jagged edges (6); b) zooming in and photographing the printed coding (4) identifier or the image-text (5) identifier to acquire photos of jagged edge features of the coding (4) identifier or the image-text (5) identifier; c) storing the photos of the jagged edge features of the coding (4) identifier or the image-text (5) identifier as secondary anti-counterfeit feature information; performing comparison on the coding (4) identifier or the image-text (5) identifier, and next if inconsistency is found, then directly returning that the product is determined to be fake; and if the comparison of the coding (4) identifier or the image-text (5) identifier shows consistency, then performing comparison on photos of the jagged edge features corresponding to the coding (4) identifier or the image-text (5) identifier. Via the micro-texture anti-counterfeit method, a coding (4) identifier or image-text (5) identifier having jagged edges (6) is formed by printing, and photos of the jagged edge features of the coding (4) identifier or the image-text (5) identifier are stored as secondary anti-counterfeit feature information. Therefore, the micro-texture anti-counterfeit method effectively prevents stolen anti-counterfeit data from being used in counterfeiting with a small increase in manufacturing and printing costs, thus realizing a simple process and easy implementation.
