Abstract

The invention discloses a watermark-embedded anti-counterfeiting two-dimensional code generation method and device. The method comprises: acquiring a printing stock, evenly printing magnetic ink on one side of the printing stock, generating the printing stock containing magnetic ink patterns after UV curing is conducted, generating an initial two-dimensional code image according to a two-dimensional code digital content database generated in advance, and performing color matching on the initial two-dimensional code image and a watermark image; decomposing the initial two-dimensional code image and the watermark image into multi-scale subset images respectively to complete embedding of the watermark image; performing inverse process operation of multi-scale decomposition on the sub two-dimensional code image embedded with the watermark image, and performing image fusion to generate a target two-dimensional code; and spraying and printing the target two-dimensional code on the magnetic ink printing area of the printed material to generate the anti-counterfeiting two-dimensional code. According to the embodiment of the invention, the two-dimensional code technology is applied to the cigarette packet product, the two-dimensional code image cannot be copied, one-product one-code, product traceability and online anti-counterfeiting are realized, and the anti-counterfeiting performance of the cigarette packet product is improved.

Description

technical field [0001] The invention relates to the technical field of commodity anti-counterfeiting, in particular to a method and device for generating an anti-counterfeiting two-dimensional code embedded with a watermark. Background technique [0002] Two-dimensional code is a new generation of barcode technology for recording data symbol information. It has multiple advantages such as high-density coding, large information capacity, wide coding range, strong fault tolerance, high compilation reliability, low cost, and easy production. Combined with mobile Internet technology, the QR code can point to any URL, text, picture, or video. [0003] QR codes have been widely used in the Internet of Things and product traceability. The construction of the Internet of Things in the fast-moving consumer goods (such as tobacco, etc.) industry is conducive to optimizing the product circulation system, realizing the optimal allocation of logistics resources in the entire industry, a...
