Bottom label of double-layer label for anti-counterfeiting

Abstract

The invention discloses a bottom label of a double-layer label for anti-counterfeiting. The bottom label is arranged as a random grain label. A manufacturing method of the bottom label comprises the following steps: 1) applying a random number generator to a randomly generating blank, gray or appointed color on any pixel position of the random bottom grain of the double-layer label; 2) performing scale invariant feature transform (SIFT) feature detection on the generated random bottom grain, storing and skipping to step 3) if detecting at least 300 obvious local irregular SIFT feature points, and if not, abandoning the generated bottom grain and skipping to step 1); and 3) accurately controlling the length and width size of the random grain when the label is printed onto a commodity package. The bottom grain of the bottom level for the anti-fake double-layer label is simple, special and not complex. The standard configuration for the bottom label is quickly realized according to the bottom grain.

Description

technical field [0001] The invention relates to anti-counterfeit trademark technology, in particular to a bottom label for anti-counterfeit double-layer labels. Background technique [0002] At present, anti-counterfeiting has become an indispensable technology for commodity circulation and sales. The current commodity anti-counterfeiting technology methods mainly include two-dimensional codes, laser holographic technology, fluorescent materials, watermark paper, etc. The semantic information of the two-dimensional code is easy to interpret but also easy to be copied; laser holographic technology, fluorescent materials, watermark paper and other methods focus on anti-counterfeiting materials and complex textures, which are high in production costs, complicated in technology and not conducive to large-scale promotion . [0003] For the double-layer label that solves this problem, a bottom label with simple and special design, low cost and good reliability is needed, which s...

Problems solved by technology

The semantic information of the two-dimensional code is easy to interpret but also easy to be copied; laser holographic technology, fluorescent materials, watermark paper and other methods focus on anti-counterfeiting materials and complex textures, which are high in production costs, complicated in technology and not conducive to large-scale promotion

[0003] For the double-layer label that appears to solve this problem, a bottom label with simple and special design, low cost and good reliability is needed, which solves the high cost problem of purely relying on complex materials and complex textures for anti-counterfeiting
