Abstract

The invention discloses a digital security encoding method with universality and high-strength characteristics, which includes a marking code encoding method developed to adapt to various sales scenarios and product shapes, a digital pairing algorithm constructed to enhance the efficiency of the marking code marking process and provide real-time marking ability, and a mathematical validation method based on overall verification and branch verification constructed to achieve accurate authenticity identification and to ensure the accuracy of verification. Digital encoding is used as the core ofthe method. The two-dimensional code is used as a demonstration body, and digital encoding serves as an assistant. Multiple levels of security are provided. The method can adapt to various anti-counterfeiting application scenarios, and is of low cost and high adaptability. Moreover, the method is of very high safety, accuracy, security and usability, and is very inexpensive.

Description

technical field [0001] The invention relates to the technical field of digital anti-counterfeiting, in particular to a digital anti-counterfeiting coding method with the characteristics of universality and high strength. Background technique [0002] Since its birth, digital anti-counterfeiting technology has gradually become a trend of product authenticity verification due to its unique advantages. At present, it has transitioned from a single digital code anti-counterfeiting technology to a two-dimensional code anti-counterfeiting technology, which can be divided into single-digit anti-counterfeiting codes and combinations. Two technical categories of digital anti-counterfeiting codes. [0003] The core number set of the single-digit anti-counterfeiting code generally adopts the traditional digital code scheme, using a simple multi-digit number as the product mark, which does not cover any physical information of the product itself, but adds a string used to point to the s...

AI Technical Summary

Problems solved by technology

[0008] 1. A single code is easy to be forged. The common method of forgery is to use one real code to forge multiple ones. This method is easy to be identified, but because consumers lack the habit of verifying the authenticity, or lack the network environment to verify before purchasing. The real operation is often exploited by the counterfeiters in a short period of time

[0009] 2. It can be judged whether the product is used by judging whether the film is damaged or not. However, for products placed in public areas such as supermarkets, the film may be maliciously damaged, causing direct losses to the merchant. Counterfeiting by means of lamination, so it is impossible to truly eliminate counterfeit goods

[0010] 3. Since the anti-counterfeiting code composed of a single number set needs to be based on a certain digital standard and algorithm to generate the unique mark of the product, as long as the generated algorithm is cracked, the counterfeiter can fake it without showing any traces. In particular, most of the current anti-counterfeiting codes are plaintext records or simple universal encryption. As long as there is a certain batch of anti-counterfeiting data samples, it is possible to crack the algorithm.

[0011] 4. In the process of commodity circulation, there may also be cases of malicious code scanning. If the judgment rules in the background system are too strict, the genuine product may be judged as counterfeit. If it is not strict enough, the goal of authenticity judgment may not be achieved at all. As a result, many anti-counterfeiting platforms currently on the market can only provide the authenticity of the anti-counterfeiting digital string and the record of the scanned code, but cannot effectively distinguish the authenticity of the product

[0012] 5. Due to the lack of a pre-sale verification mechanism in the circulation of commodities, many consumers scan the codes of the commodities out of curiosity, resulting in the anti-counterfeit codes being scanned multiple times after the commodities are sold. Information prompt that the anti-counterfeiting code has expired

[0013] 6. The production process of using combined codes is very complicated and lacks universality. It can only be used for specific industries or packaging methods. It requires special coding equipment and software systems, and must be completely embedded in the production and packaging of products to form combined codes. One-to-one relationship; therefore, it will inevitably increase production costs and require continuous investment, which directly affects the enthusiasm of enterprises for brand building

[0014] 7. It is very inconvenient to use the combination code. It is necessary to obtain the code inside the package after opening the package to determine the authenticity. Consumers must verify the authenticity after purchase. However, because the outer package has been damaged, merchants often Excuse on the grounds that the product has been used or the package has been damaged, which makes it difficult for consumers to protect their rights

[0017] 10. The existing technical solutions for the authenticity identification method of bulk commodities cannot be solved

[0018] 11. It is impossible to identify the authenticity in the absence of the network, and only return to the area with the network to scan the code after purchase, so that time and space have changed, which will lead to difficulties in counterfeit rights protection

[0019] 12. There is a lack of a pre-sale verification method, which will not affect the sales of the product, but also allow consumers to understand the situation and authenticity of the product before buying

[0020] The main reason is that there are limitations in the consideration of the application environment, the consideration of the encoding method, the consideration of the data model, the consideration of the core algorithm and the consideration of the judgment standard.
