Problems solved by technology

[0008] 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 complicated 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
[0009] 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

Embodiment 1

[0081] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random droplets includes two basic components: 10-18 random droplets 1 and a three-dimensional carrier 2 capable of accommodating all random droplets 1, and the three-dimensional carrier 2 is made of PC material , can pass through visible light so that the random droplet 1 can be identified by the image recognition device; the positions of the random droplet 1 in the three-dimensional carrier 2 are randomly distributed, and there are at least 3 random droplet 1 whose center of gravity coordinates are in 3 On parallel but different planes; the image features of random droplet 1 and three-dimensional carrier 2 are recorded in the database for comparison and recognition by image recognition equipment; three-dimensional anti-counterfeiting labels are divided into front and back, and the front is used for being recognized by image recognition equipment. The image recognition equipment scans and...

Embodiment 2

[0083] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random droplets includes two basic components: 15-25 random droplets 1 ; and a three-dimensional carrier 2 capable of accommodating all random droplets 1 . The three-dimensional carrier 2 is made of PMMA material, and the three-dimensional carrier 2 can pass through visible light so that the random droplets in it can be recognized by the image recognition equipment; in the photos obtained by taking the three-dimensional anti-counterfeiting label from any angle, the area of ​​the random droplet 1 occupies The proportion of the total area of ​​the three-dimensional anti-counterfeiting label is 80-90%; the front of the three-dimensional anti-counterfeiting label is photographed by an image acquisition device, and the image characteristics of the combination of the random droplet 1 and the three-dimensional carrier 2 are obtained and recorded in the database for use by the image recognition dev...

Embodiment 3

[0085] Such as figure 1 As shown, a three-dimensional anti-counterfeiting label based on random droplets includes two basic components: 20-25 random droplets 1 and a three-dimensional carrier 2 capable of accommodating all random droplets. The three-dimensional carrier 2 is made of PS material, It can transmit visible light so that the random droplets 1 can be recognized by the image recognition equipment; the positions of the random droplets 1 in the three-dimensional carrier 2 are randomly distributed, and there are at least 7 random droplets 1 whose center of gravity coordinates are in 7 different positions. On a parallel plane, the distance between two droplets is not particularly limited; the image features of the combination of random droplets 1 and 3D carrier 2 are recorded in the database for comparison and identification by image recognition equipment; 3D anti-counterfeiting The label is divided into front and back, where the front is used to be scanned and recognized...

Abstract

The invention relates to a three-dimensional anti-counterfeit label based on random liquid drops. The three-dimensional anti-counterfeit label includes random liquid drops and a three-dimensional carrier capable of accommodating all the random liquid drops. The random liquid drops in the three-dimensional carrier are randomly distributed; image features of combination of the random liquid drops and the three-dimensional carrier are recorded in a database; and the random liquid drops are used for being compared and recognized by an image recognition device. Pre-sale inspection on a counterfeitof 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 counterfeitof the goods.

Description

technical field [0001] The invention relates to a three-dimensional anti-counterfeiting label based on random liquid droplets, belonging to the field of anti-counterfeiting. [0002] The term "mechanical connection" includes riveting, bolt connection, key pin connection, elastic snap connection and other methods. [0003] The term "welding": refers to the use of electrical energy, chemical energy, mechanical energy to join two objects together. [0004] The term "centroid coordinates": refers to the coordinates of the geometric center of gravity of an object, regardless of the density factor of the object. [0005] The term "random droplet" refers to a droplet with random shape and volume, which is located inside the three-dimensional carrier and formed by wrapping the gas in the three-dimensional carrier. [0006] The term "random droplet on the bonding surface" refers to a droplet with random shape and volume, which is located on the bonding surface between one outer surfa...
