Description
Technical Field
The invention relates to a three-dimensional anti-counterfeit label based on trace random bubbles, and belongs to the field of anti-counterfeit.
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.
The term "random bubbles": the bubble is positioned inside the three-dimensional carrier, and is formed by wrapping gas by the three-dimensional carrier.
The term "bonding surface random bubbles": the three-dimensional anti-counterfeit label is characterized by comprising bubbles with random appearance and volume, wherein the bubbles are positioned on the bonding surface of one outer surface of the three-dimensional anti-counterfeit label and corresponding goods, and the bubbles are formed by wrapping gas by an adhesive.
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.

Compared with the existing anti-counterfeiting label, the anti-counterfeiting label has the advantages that according to the technical scheme, at least 7 of the following 8 elements (including user requirements, product advantages and technical advantages) can be simultaneously realized: (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.
According to the invention, the three-dimensional anti-counterfeiting label based on the random bubbles can be composed of only two parts, namely at least 18 random bubbles and a three-dimensional carrier capable of containing all the random bubbles, and the anti-counterfeiting label has the advantages of simple structure, easiness in manufacturing and low cost.
According to the invention, random bubbles are randomly generated and distributed in the three-dimensional carrier, compared with random patterns of other physical states (such as solid or liquid), the random bubbles are almost impossible to imitate, and the probability of generating bubbles with the same quantity, the same shape and the same position in two different labels is very low. Under the prior art, the imitation is almost impossible.
According to the invention, when random bubble characteristics are acquired from different angles, the thickness of the three-dimensional carrier between the image acquisition equipment and the bubbles is different, and in addition, an included angle exists between different outer surfaces of the three-dimensional carrier and the complex influence of refraction light rays between the bubbles causes at least two characteristic changes of random bubble images acquired from different angles: the image characteristic change generated based on different random bubble positions and the image characteristic change generated based on the light refraction angle change. Both of these feature changes are recorded in the database. This transient fixed feature is difficult to trace back and difficult to impersonate.
According to the invention, the number of the random bubbles is 1-3, and compared with more random bubbles, the method not only provides the possibility of reducing the manufacturing process cost, but also provides the possibility of miniaturizing the anti-counterfeit label.
According to the invention, the anti-counterfeit label must be comprehensively identified from different angles to confirm the authenticity of the commodity. For the anti-counterfeiting participants, only the image recognition equipment (such as a mobile phone) needs to be rotated, and for the counterfeiters, the counterfeiting cost is very high.
According to the invention, the image features of the random bubbles combined with the three-dimensional carrier are recorded in the database, and the counterfeit label is easily checked and falsified because the contrast information cannot be found in the database.
According to the invention, the random bubble area accounts for not more than 60% of the total area of the three-dimensional anti-counterfeit label, so that the manufacturing cost of the random bubbles is saved, the cost of embedding the random bubbles into the three-dimensional carrier is saved, and meanwhile, the reserved at least 5% blank recognition position can facilitate the positioning and recognition of the image recognition equipment, and the counterfeit difficulty is increased.
According to the invention, all random bubbles can be at least divided into two types according to different shape or volume characteristics, so that the image randomness of the random bubbles at any angle is greatly increased, and the occurrence probability of similar or identical images is reduced. Meanwhile, the invention also provides other technical schemes capable of realizing the same functions, such as: (1) The outer surface of the three-dimensional anti-counterfeiting label at least comprises 3 surfaces, and at least 2 surfaces are plane surfaces; (2) The inside or the outside of the three-dimensional carrier also comprises random fluorescent powder, the position of the random fluorescent powder is random, the maximum particle size diameter of the random fluorescent powder is 0.05-1.2mm, and the random fluorescent powder can be recorded and used as a part of image characteristics when the front of the three-dimensional anti-counterfeiting label is shot by using image acquisition equipment; (3) The three-dimensional carrier also comprises planar glitter powder, wherein the length and the width of the planar glitter powder are within the range of 1.5-8mm, and the thickness of the planar glitter powder is 0.1-0.8mm, and the planar glitter powder can be recorded and used as part of image characteristics when the front surface of the three-dimensional anti-counterfeiting label is shot by using image acquisition equipment; etc.
