Problems solved by technology

[0002] Existing anti-counterfeiting technologies mostly use printed marks and patterns for anti-counterfeiting. The anti-counterfeiting marks or anti-counterfeiting codes provided are highly reproducible and the anti-counterfeiting effect is poor, making it difficult for consumers to verify the authenticity of products.
Unscrupulous elements use the defects of existing anti-counterfeiting technology to produce counterfeit products for personal gain, endanger the interests of consumers, and cause serious adverse effects on social and economic order.
In this environment, the use of dynamically variable anti-counterfeiting technology can overcome the reproducibility defects of existing anti-counterfeiting technology, and has the advantages of good anti-counterfeiting effect and high reliability. Therefore, it is possible to identify and verify dynamically variable anti-counterfeiting marks It is of practical significance to verify the authenticity of the product, and even further trace the product after the verification is completed. Therefore, it is necessary to propose an identification and verification method that matches the anti-counterfeit label for dynamically variable anti-counterfeit labels

Embodiment 1

[0039] Embodiment 1 provides an identification and verification method based on a dot matrix screen anti-counterfeit label, including two parts: image recognition and counterfeit verification comparison, identifying the anti-counterfeit area of ​​the dot matrix screen anti-counterfeit label to obtain a sequence code representing a random pattern, It provides comparison data for the counterfeit verification process of the subsequent dot matrix screen anti-counterfeit labels. During the counterfeit verification comparison process, the dynamic verification template is used for synchronous clock comparison to realize dynamic counterfeit verification; random graphics are dynamically changed under different clock data, It has randomness, so it is non-reproducible. Using a dot matrix screen anti-counterfeiting label that dynamically displays random graphics has a better anti-counterfeiting effect. Based on this kind of dot matrix screen anti-counterfeiting label, a counterfeit verifica...

Embodiment 2

[0053] The difference between this embodiment and the above-mentioned embodiment is that, according to the sequence code algorithm, the target sequence code in the anti-counterfeit label image of the dot matrix screen is identified, and the sequence code recognition algorithm is introduced, as follows image 3 As shown, it includes the following steps:

[0054] Obtaining the anti-counterfeiting label image of the dot matrix screen, and preprocessing the anti-counterfeiting label image of the dot matrix screen;

[0055] Extracting the target anti-counterfeiting area from the preprocessed dot matrix screen anti-counterfeiting label image;

[0056] Thresholding the target anti-counterfeiting area to obtain a binarized image, dividing the binarized image into 8×8 blocks, and these blocks have the same size, of course, in other embodiments, these 8×8 blocks The blocks can also be unequal, and the proportion of the foreground pixels in each block is calculated. If the proportion is...

Embodiment 3

[0078] Embodiment 3 discloses a device corresponding to the identification and verification method based on the dot matrix screen anti-counterfeit label corresponding to the above embodiment, which is the virtual device structure of the above embodiment, such as Figure 4 As shown, a kind of identification verification device based on dot matrix screen anti-counterfeiting label, it comprises:

[0079] The image acquisition module 410 is used to acquire the anti-counterfeiting label image of the dot matrix screen, and identify and upload the barcode information in the anti-counterfeiting label image of the dot matrix screen;

[0080] The serial code identification module 420 is used to identify the anti-counterfeiting label image of the dot matrix screen to obtain the target serial code, and upload the target serial code for counterfeit verification comparison;

[0081] The result display module 430 is used to receive and display the counterfeit verification and comparison resu...
