Embodiment 1

[0035] Such as figure 1 As shown, an anti-counterfeiting label is composed of four layers, including a substrate 1, an infrared ink anti-counterfeiting layer 2, an infrared ink coding layer 3 and a visible pattern layer 4 from bottom to top. The infrared ink anti-counterfeiting layer 2 , the infrared ink coding layer 3 and the visible pattern layer 4 are all arranged on the substrate 1 by printing. The substrate 1 shown can be a paper surface, a plastic surface, a cloth surface, or the like. Two-dimensional code patterns arranged in a predetermined manner are formed on the infrared ink coding layer 3 . The two-dimensional code pattern is printed with carbon-containing black ink or carbon-containing colorless ink. The ink used in the infrared ink anti-counterfeiting layer 2 is carbon-containing black ink or carbon-containing colorless ink.

[0036] Wherein, under the irradiation of infrared light, the spectral attenuation characteristics of the infrared ink coding layer 3 ar...

Embodiment 2

[0050] Such as Figure 4 As shown, the difference between the present embodiment and the first embodiment lies in the structure of the anti-counterfeiting label. Specifically, the anti-counterfeit label of this embodiment has a three-layer structure, which is a substrate 1, an infrared ink coded anti-counterfeit composite layer 2' and a visible pattern layer 3' from bottom to top. The infrared ink coding anti-counterfeiting composite layer 2' includes an infrared ink coding layer and an infrared ink anti-counterfeiting layer, that is, the infrared ink coding layer and the infrared ink anti-counterfeiting layer are located on the same layer. The implementation method is that before printing, the ink of the infrared ink coding layer and the ink of the infrared ink anti-counterfeiting layer can be blended together, and then printed on the substrate in the form of a two-dimensional code pattern. This can save one layer of printing and simplify the process of making anti-counterfe...

Embodiment 3

[0053] Such as Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the structure of the infrared light source. Specifically, the infrared light source in this embodiment is an infrared LED 5 ′, that is, the same infrared LED is used as the illumination source. Certainly, a plurality of infrared LEDs having the same wavelength as the infrared light of the infrared LED 5 ′ can also be added to be used as auxiliary light sources when the light intensity is insufficient.

[0054] The anti-counterfeit label of this embodiment may be the same as that of Embodiment 1 or Embodiment 2, and the identification method of the anti-counterfeit label of this embodiment is the same as that of Embodiment 1.

Abstract

The invention relates to an anti-counterfeit label as well as a recognizing device and a recognizing method thereof. The recognizing method comprises the following steps of utilizing an infrared source to radiate an infrared ink anti-counterfeit layer of the anti-counterfeit label; utilizing a photosensitive receiving tube to detect spectrum attenuation characteristics of the infrared ink anti-counterfeit layer after being radiated; and utilizing a processor to compare the spectrum attenuation characteristics detected by the photosensitive receiving tube with the spectrum attenuation characteristics prestored in a storage device, instructing the infrared source to radiate an infrared ink code layer of the anti-counterfeit label so as to allow an image sensor to read a two-dimensional code pattern of the infrared ink code layer if the detected spectrum attenuation characteristics are matched with the spectrum attenuation characteristics prestored in the storage device, utilizing the processor to decode the two-dimensional code pattern, and stopping the work if the detected spectrum attenuation characteristics are not matched with the spectrum attenuation characteristics prestored in the storage device. Through the double recognition, the anti-counterfeit label can be prevented from being cracked by copying the two-dimensional code pattern.

Description

technical field [0001] The invention relates to anti-counterfeiting technology, in particular to anti-counterfeiting labels, identification devices and methods for anti-counterfeiting labels. Background technique [0002] The current anti-counterfeiting labels are generally composed of a substrate, an infrared ink coding layer printed on the substrate, and a visible pattern layer. The infrared ink coding layer has a two-dimensional code pattern arranged in a small dot matrix, and the ink that constitutes the two-dimensional code pattern The dots can be carbon-containing black ink or carbon-containing colorless ink, and the two-dimensional code pattern is an invisible two-dimensional code. When identifying, the infrared ink coding layer is irradiated by the infrared LED, and then the two-dimensional code pattern of the infrared ink coding layer is read by the camera, and then the processor is used to decode the two-dimensional code pattern and judge whether the two-dimensiona...
