Anti-counterfeit label based on trace amount two-dimensional random graphics

Abstract

The invention relates to an anti-counterfeit label based on trace amount two-dimensional random graphics. The label includes 1-3 two-dimensional random graphics and a three-dimensional carrier capableof accommodating all the two-dimensional random graphics. The two-dimensional random graphics in the three-dimensional carrier are randomly distributed; image features of combination of the two-dimensional random graphics and the three-dimensional carrier are recorded in a database; and the two-dimensional random graphics are used for being compared and recognized by an image recognition device.Pre-sale inspection on a counterfeit of goods can be achieved; and the label has the characteristics of non-replicability and non-recyclability, and provides the possibility for the public to participate in inspection on the counterfeit of the goods.

Description

technical field [0001] The invention relates to an anti-counterfeiting label based on trace two-dimensional random graphics, which belongs to the field of anti-counterfeiting. [0002] The term "two-dimensional random graphics", where "dimension" is the direction dimension in the concept of space system, "two-dimensional random graphics" in this patent means that one direction dimension in the three-dimensional random graphics is relatively weakened so that it can be ignored Generally speaking, "two-dimensional random graphics" can be expressed as "plane random graphics", or more precisely, "two-dimensional random graphics" can be expressed as "thickness is extremely small, and its appearance is mainly based on two a figure embodied by two parallel outer surfaces" or "so thin that its two outer surfaces appear to be on a plane", for example, a sheet of arbitrarily shaped, extremely thin flat paper. [0003] The term "mechanical connection" includes riveting, bolt connection, ...

Problems solved by technology

[0006] However, so far, for bulk consumer products, the public has not only never become a participant in the counterfeit inspection of commodities, but even ignores most of the anti-counterfeit labels. There are three main reasons for this: First, the counterfeit inspection technology is complex Or the counterfeit inspection equipment is expensive, and it is difficult for the public to participate in it, and the extremely low participation of the public makes it difficult to form credibility; second, most anti-counterfeiting technologies use one-dimensional or two-dimensional label products as carriers, while anti-counterfeiting labels lower than three-dimensional are all Inevitably, it is easy to be copied, recycled or forged; the third is the cost issue. It is true that many anti-counterfeiting technologies are difficult to crack, but the anti-counterfeiting labels are expensive and difficult to be accepted by commodity manufacturers

[0007] In short, in the current anti-counterfeiting industry, no anti-counterfeiting label has been found that can take into account the following elements at the same time: (1) facilitate the public to participate in large-scale counterfeiting verification; (2) realize pre-sale counterfeiting inspection of products; (3) cannot be copied; (4) Cannot be recycled; (5) Low probability of counterfeiting; (6) Low cost; (7) Applicable to a variety of commodities in all walks of life; (8) High cost of counterfeiting
