Description
Translated fromChinese技术领域technical field
本发明涉及一种堆叠三维码的生成方法、系统、设备和存储介质，属于编码符号处理技术领域。The invention relates to a method, system, device and storage medium for generating stacked three-dimensional codes, and belongs to the technical field of coding symbol processing.
背景技术Background technique
随着二维码应用越来越广泛，现在无论是商品包装还是产品防伪溯源都出现了二维码的应用。在商品包装中，通过给产品赋码，可让用户扫码了解产品的详细信息，让用户进一步了解产品的优势，从而达到一定的营销效果；同时也可让用户扫码通过后台查询验证所购买商品的真伪。As the application of two-dimensional codes becomes more and more widespread, the application of two-dimensional codes has appeared in both commodity packaging and product anti-counterfeiting traceability. In the product packaging, by assigning a code to the product, users can scan the code to understand the detailed information of the product, so that users can further understand the advantages of the product, so as to achieve a certain marketing effect; at the same time, users can also scan the code to verify the purchase through the background query The authenticity of the product.
二维码虽然在商品流通和防伪溯源领域得到了广泛的应用，但由于其自身缺陷带来了一些无法解决的问题，一是二维码由黑白块组成，人眼不容易辨识其内容，所以容易被篡改和替换，从而给不法分子带来可趁之机；二是二维码的防伪溯源通常要结合后端系统，而后端系统也容易被伪造，所以通过该种方式的防伪仍存在不可信因素；三是二维码虽然有一定的容错能力，但容易遭到污损破坏从而无法识别，从而给防伪溯源工作带来一定难度。Although the two-dimensional code has been widely used in the field of commodity circulation and anti-counterfeiting traceability, it has brought some unsolvable problems due to its own defects. It is easy to be tampered with and replaced, which brings opportunities for criminals; second, the anti-counterfeiting traceability of the two-dimensional code usually needs to be combined with the back-end system, and the back-end system is also easy to be forged, so the anti-counterfeiting through this method still exists. The third is that although the two-dimensional code has a certain fault tolerance, it is easy to be defaced and damaged and cannot be recognized, which brings certain difficulties to the work of anti-counterfeiting and traceability.
为了解决上述技术问题，专利号为“CN103489026B”公开了一种彩色二维码及其生成方法，具体公开了以下技术方案：“S1、基于第一目标物信息生成原始二维码，在所述原始二维码的部分或者全部区域填充颜色；S2、基于第二目标物信息生成点阵码；S3、将生成的点阵码叠加到填充了颜色的原始二维码的部分或者全部区域，以生成彩色二维码，通过在填充了颜色的原始二维码的部分或者全部区域叠加点阵码从而生成最终的彩色二维码，进一步提高了整体的编码密度，加密性强，提高了破解和仿造的难度。另外，基于第一目标物信息计算预定个数的颜色代码，然后按照填充顺序将预定个数的颜色代码分别填充到原始二维码被划分出的预定个数的区域中，从而生成了颜色按照一定逻辑变化的二维码。”In order to solve the above technical problems, the patent No. "CN103489026B" discloses a color two-dimensional code and its generation method, and specifically discloses the following technical solutions: "S1. Generate the original two-dimensional code based on the information of the first object, in the Part or all of the original two-dimensional code is filled with color; S2, generating a dot matrix code based on the second target information; S3, superimposing the generated dot matrix code on part or all of the original two-dimensional code filled with color, to Generate a color two-dimensional code, and generate the final color two-dimensional code by superimposing the dot matrix code on part or all of the original two-dimensional code filled with color, which further improves the overall coding density, strong encryption, and improves cracking and Difficulty of imitation. In addition, calculate the color code of predetermined number based on the first object information, then according to filling sequence, the color code of predetermined number is respectively filled in the area of predetermined number that original two-dimension code is divided, thereby A QR code whose color changes according to a certain logic is generated."
上述现有技术通过融合点阵码以及颜色代码，提高了二维码的编码密度和破译难度；但是本质上是在二维码上加上颜色，生成方式复杂麻烦，且改造后的二维码还是容易被篡改、伪造。The above-mentioned existing technology improves the coding density and deciphering difficulty of the two-dimensional code by fusing the dot matrix code and the color code; It is still easy to be tampered with and forged.
