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, endangering the interests of consumers, and causing serious adverse effects on social and economic order.

Example Embodiment

[0038] Example 1

[0039] Embodiment 1 provides a method of identifying and verifying forgery based on LCD anti-counterfeiting labels, including two parts: character password recognition and verification and comparison. The dynamic character password obtained by recognizing the LCD anti-counterfeiting label is the subsequent verification of the LCD anti-counterfeiting label. The process provides comparison data. In the verification and comparison process, the dynamic verification template is used to synchronize the clock to achieve dynamic verification. The dynamic character password has randomness and uniqueness under different clock data, so it cannot be copied. LCD anti-counterfeiting labels that use dynamic character passwords have better anti-counterfeiting effects. Based on this LCD anti-counterfeiting label, a method of verification is introduced for users to use.

[0040] Such as figure 1 As shown, the method for identification and verification based on LCD anti-counterfeit...

Example Embodiment

[0052] Example 2

[0053] The difference between this embodiment and the foregoing embodiment is that the target character password in the LCD anti-counterfeiting label image is recognized according to the character password recognition algorithm, and the character password recognition algorithm is introduced, such as figure 2 As shown, it includes the following steps:

[0054] Acquiring an LCD anti-counterfeiting label image, and preprocessing the LCD anti-counterfeiting label image;

[0055] Extracting the anti-counterfeiting area from the pre-processed LCD anti-counterfeiting label image;

[0056] A character positioning model is used to locate the character area of ​​the anti-counterfeiting area, and a convolutional neural network is used to recognize the character password in the character area to obtain the target character password.

[0057] In this embodiment, the operation of preprocessing the LCD anti-counterfeiting label image is: converting the LCD anti-counterfeiting label...

Example Embodiment

[0086] Example 3

[0087] Embodiment 3 discloses a device corresponding to the method of identifying and verifying forgery based on LCD anti-counterfeiting labels corresponding to the above embodiment, which is the virtual device structure of the above embodiment, such as Figure 4 As shown, an identification and verification device based on an LCD anti-counterfeiting label includes:

[0088] The image acquisition module 410 is configured to acquire an LCD anti-counterfeiting label image, and to recognize and upload the barcode information in the LCD anti-counterfeiting label image;

[0089] The character password recognition module 420 is used to recognize the target character password in the LCD anti-counterfeiting label image, and upload the target character password for forgery verification and comparison;

[0090] The result display module 430 is used to receive and display the result of the verification and comparison.

[0091] Preferably, identifying the target character password...

Abstract

The invention discloses an LCD anti-counterfeit label-based identification and counterfeit detection method, and relates to the technical field of counterfeiting prevention, for solving the problem ofdynamic counterfeit detection of an LCD anti-counterfeit label. The LCD anti-counterfeit label-based identification and counterfeit detection method comprises the following steps: acquiring an LCD anti-counterfeit label image, identifying and uploading bar code information in the LCD anti-counterfeit label image; identifying a target character password in the LCD anti-counterfeit label image, anduploading the target character password to perform counterfeit detection comparison; and receiving a counterfeit detection comparison result. The invention also discloses an LCD anti-counterfeit label-based identification and counterfeit detection device, electronic equipment and a computer storage medium. According to the invention, the LCD anti-counterfeit label is subjected to dynamic passwordidentification and authenticity verification comparison, so that identification and authenticity verification of the LCD anti-counterfeit label are completed.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to a method, device, equipment and medium for identifying and verifying counterfeit based on LCD anti-counterfeiting labels. Background technique [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, but the anti-counterfeiting effect is poor, making it difficult for consumers to verify the authenticity of products. Unscrupulous elements take advantage of 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 technol...
