Spherical anti-counterfeiting label based on dynamic password

Abstract

The invention relates to a spherical anti-counterfeiting label based on a dynamic password. The spherical anti-counterfeiting label includes a label identity carrier unit, a dynamic password display unit, a dynamic password arithmetic unit and a spherical anti-counterfeit label shell. Through adoption of a primary encryption algorithm or iteration encryption algorithm, the anti-counterfeiting performance of the label is ensured, and 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 a spherical anti-counterfeiting label based on a dynamic password, which belongs to the field of anti-counterfeiting. Background technique [0002] After years of development of anti-counterfeiting technology, many categories have been formed, such as laser holographic film, laser holographic anodized aluminum film, laser holographic plus fluorescent anti-counterfeiting film, flexible laser holographic anti-counterfeiting film, optical color-changing interference film, optical retro-reflective film, nuclear micro Anti-counterfeiting film technology represented by porous film, optical lens spherical display anti-counterfeiting film, three-dimensional imaging anti-counterfeiting film, pressure-sensitive polymer porous composite film, etc., color dot encrypted paper, fluorescent encrypted paper, anti-copy paper, invisible printing anti-counterfeiting coating Anti-counterfeiting paper (packaging) technology represented by paper, an...

Problems solved by technology

[0003] 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, and anti-counterfeiting labels that are lower than spherical 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

[0004] 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

[0005] Two invention patents with application numbers 201410605962.x and 201410606036.4 respectively disclose a clock-synchronized dynamic password anti-counterfeiting label and an event-type dynamic password anti-counterfeiting label, both of which can effectively realize anti-counterfeiting, but have the following defects: (1) spherical The label system is complex, including at least 6 units, resulting in a large overall label size; (2) The image acquisition unit in the user verification terminal module must collect both the dynamic password data and the label ID, which leads to: either two-step acquisition is required 1. Increase the user's fabrication steps; or put the dynamic password data and label ID on the same (or parallel) plane, increasing the limiting factors of the label making process; (3) directly output the dynamic password on the display interface, and according to It is common knowledge in this field that the dynamic password must be at least 4-8 digits (mostly Arabic numerals). In order to meet the requirements of the identification device, each number must also ensure that it occupies a sufficient two-dimensional area, resulting in the overall area of ​​the label must be large enough, It cannot be as small as possible; (4) There is no public dynamic password algorithm; (5) The image data of the dynamic password data display interface must be collected, which means that image recognition operations such as positioning, segmentation, and analysis must be performed on the collected image data. However, this calculation is not necessary; (6) There is no technical constraint on the position of each component
