Three-dimensional anti-counterfeit label based on random liquid drops

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...

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
