Anti-counterfeiting identification with interference element layer and method and device for identifying anti-counterfeiting identification with interference element layer

Abstract

The invention provides anti-counterfeiting identification with an interference element layer. The color of an identification layer and the color of the interference element layer belong to the same color system, the identification layer is covered with the interference element layer and characterized in that coatings capable of absorbing light invisible to the eyes are attached to a carrier, and light used for reading raster graphics can reach the raster graphics through the interference element layer. A method for identifying the anti-counterfeiting identification includes the steps that the light passes through the interference element layer to read the raster graphics; images of the raster graphics are analyzed to form raster graphic data capable of being identified; the raster graphic data are verified to distinguish the authenticity of the raster graphics and feed back relevant information. A device for achieving the method comprises an infrared reading module, a judgment module, a raster graphic image feedback module, an analysis module, a raster graphic database and a feedback module. According to the anti-counterfeiting identification and the method and the device for identifying the anti-counterfeiting identification, the identification layer can be shielded and covered with the interference element layer, and influences on identifying of the identification layer are avoided.

Description

technical field [0001] The invention relates to an anti-counterfeit mark, in particular to an anti-counterfeit mark with an interfering element layer and its identification method and device. Background technique [0002] At present, the anti-counterfeiting label generally consists of a substrate, an identification layer and a visible pattern layer printed on the substrate. The Chinese patent with the publication number CN102968927A published on March 13, 2013 relates to an anti-counterfeit label, an identification device and method for an anti-counterfeit label, the anti-counterfeit label includes a substrate, and an infrared ink coding layer and infrared ink printed on the substrate The anti-counterfeiting layer, the infrared ink coding layer is located above the infrared ink anti-counterfeiting layer. By adding an infrared ink anti-counterfeiting layer to the traditional anti-counterfeiting label, the specific spectral attenuation characteristics are used as the first an...

Problems solved by technology

[0003] However, since the infrared ink coding layer is located above the infrared ink anti-counterfeiting layer, and both are made of infrared ink, when the infrared identification device identifies the label, the infrared rays sent from the infrared identification device must pass through the coding layer to be detected. Reaching the anti-counterfeiting layer will inevitably affect the accuracy of anti-counterfeiting layer identification
