Description
Technical Field
The invention relates to a three-dimensional anti-counterfeiting label based on a two-dimensional random pattern, and belongs to the field of anti-counterfeiting.
The term "two-dimensional random pattern", wherein "dimension" is a directional dimension in the concept of a spatial system, in this patent "two-dimensional random pattern" refers to a random pattern in which one directional dimension in a three-dimensional random pattern is relatively weakened so as to be negligible; in colloquial terms, "two-dimensional random pattern" may be expressed as a "planar random pattern", or, to be relatively precise, "two-dimensional random pattern" may be expressed as a "pattern having a very small thickness, whose appearance is exhibited predominantly by two parallel outer surfaces", or as a "pattern having a very small thickness such that its two outer surfaces appear to be on a single plane", for example, a sheet of arbitrarily shaped, very thin, flat paper.
The term "mechanically coupled": including riveting, bolting, keying, elastic snap-on, etc.
The term "weld": refers to a mode of combining two objects by using electric energy, chemical energy and mechanical energy.
Background
Through years of development of anti-counterfeiting technology, various categories of anti-counterfeiting technologies have been formed, such as anti-counterfeiting film technologies represented by laser holographic films, laser holographic electrochemical aluminum films, laser holographic fluorescence anti-counterfeiting films, flexible laser holographic anti-counterfeiting films, optical color changing interference films, optical reflection films, nuclear microporous films, optical lens three-dimensional display anti-counterfeiting films, three-dimensional imaging anti-counterfeiting films, pressure-sensitive polymer multi-void coincidence films and the like, anti-counterfeiting paper (packaging) technologies represented by color point encryption paper, fluorescent encryption paper, anti-copying paper, invisible printing anti-counterfeiting coated paper, anti-counterfeiting pressure-sensitive paper, layered dyeing anti-counterfeiting paper, atomic nucleus encryption anti-counterfeiting paper and the like, anti-counterfeiting tape technologies represented by self-inspection tamper protection tapes, plastic film packaging sealing materials, image-text vanishing anti-counterfeiting tapes, optical fiber anti-counterfeiting sealing materials and the like, and special material anti-counterfeiting technologies represented by document anti-counterfeiting materials, atomic nucleus double-card encryption films, anti-counterfeiting gold foils, polypropylene anti-counterfeiting fibers, nanometer anti-counterfeiting materials and the like.
However, for a large number of consumer products, the public has never become a participant in commodity inspection, and even has a desertification state for most of anti-counterfeit labels, and three main reasons are: firstly, the fake-verification technology is complex or the fake-verification equipment is expensive, the public is difficult to participate in, and the extremely low participation degree of the public leads to difficulty in forming public confidence; secondly, most of anti-counterfeiting technologies take one-dimensional or two-dimensional label products as carriers, and anti-counterfeiting labels lower than three-dimensional labels are inevitably easy to copy, recover or forge; thirdly, the cost problem is that a lot of anti-counterfeiting technologies are difficult to crack, but the anti-counterfeiting label is high in price and is difficult to accept by commodity manufacturers.
In summary, in the current anti-counterfeiting industry, an anti-counterfeiting label capable of simultaneously considering the following elements is not found: (1) facilitating the mass participation of the public in the verification; (2) realizing commodity sale pre-verification; (3) cannot be duplicated; (4) cannot be recovered; (5) the forging probability is low; (6) low cost; (7) a plurality of goods suitable for each industry; (8) the forging cost is high.
