Description

An anti-counterfeiting label and anti-counterfeiting verification method based on fractal graphics

technical field

The invention relates to the technical field of identity identification and anti-counterfeiting, in particular to an anti-counterfeiting label and an anti-counterfeiting verification method based on fractal graphics.

Background technique

With the intensification of market competition, all kinds of counterfeit goods flood the market, which not only causes losses to consumers, but also brings loss of integrity to manufacturers and sellers. Manufacturers also look forward to an anti-counterfeiting method that can meet the needs of their products, and with the rapid development of modern logistics sales models, the use of computer network technology to build a traceability network from manufacturers to consumers has become the most basic requirement of modern logistics sales models . Therefore, the current anti-counterfeiting method will be more competitive if it can also meet the requirements of modern logistics network management on the premise of having anti-counterfeiting functions.

Traditional signs are mainly one-dimensional barcodes and two-dimensional codes. One-dimensional barcodes are marks composed of a group of regularly arranged bars, spaces and corresponding characters. The data composed of these bars and spaces express certain information, and can be used in specific device reading. Two-dimensional barcode/two-dimensional code is a black-and-white pattern distributed in a plane (two-dimensional direction) to record data symbol information with a specific geometric pattern, which can be automatically identified by image input equipment or photoelectric scanning equipment. Reading to realize automatic processing of information is a further step forward compared to one-dimensional barcodes. It has high-density coding, large information capacity, strong error tolerance, error correction function, and encryption measures can be introduced. Although they can be marked and meet the requirements of modern logistics network management, a common shortcoming of them is that they can be copied and cannot be used for anti-counterfeiting.

Nowadays, the technology that meets the requirements of anti-counterfeiting and modern logistics network management is mainly represented by RFID radio frequency anti-counterfeiting technology. RFID radio frequency identification is a non-contact automatic identification technology. Its most prominent feature is that it can be read and uniquely identified without contact , anti-counterfeiting, anti-harsh environment, etc. However, the encryption method of RFID has been cracked, the encrypted information can be copied, and the confidentiality has been greatly reduced. In addition, the cost of RFID tags is relatively high, and its cost mainly consists of RFID chips (including radio frequency devices and storage devices) and chip packaging costs, so the cost (basically more than one yuan) has always been the biggest problem restricting its wide application, especially It is for cheap and low-margin goods.

Fractal graphics are a kind of graphics with aesthetic appeal and scientific connotation generated by using specific mathematical functions or models. Different parameters correspond to different fractal graphics. It is obviously different and can be identified by the naked eye and image recognition software, so fractal graphics cannot be forged by means of shooting and scanning, and fractal graphics can be automatically recognized by graphic recognition software.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and to provide a kind of anti-counterfeiting label based on fractal graphics that is widely used, simple to manufacture, low in cost and does not contain any electronic components but possesses most of the functions of RFID tags and Its anti-counterfeiting method.

Technical scheme of the present invention:

An anti-counterfeiting label based on fractal graphics includes an identification code, a fractal graphic number, a label carrier, and a fractal graphic. The identification code, the fractal graphic number label carrier, and the fractal graphic are all set on the label carrier.

The label carrier is also provided with an information writing area, and the information writing area prints encrypted information according to customer needs.

The fractal figure number and the fractal figure are randomly generated by a computer and have relevance; the fractal figure has different shapes with different fractal figure numbers.

An anti-counterfeit verification method applied to anti-counterfeit labels, comprising the following steps:

1) The computer randomly generates relevant identification codes, fractal graphic numbers, and fractal graphics, and prints the identification codes, fractal graphic numbers, and fractal graphics on the label carrier;

2) Print encrypted information or not print information in the information writing area on the label carrier according to customer needs;

3) Store the information of the fractal figure number, fractal figure and information writing area in the anti-counterfeiting database, and stick the label on the item;

4) When the appearance of the label is complete and the fractal figure is the original image, enter the identification code to query, and the query result is consistent with the fractal figure number, fractal figure, and information writing area on the label, then it is genuine, otherwise the item has been repackaged or Counterfeit; when the fractal graph is defective or the fractal graph is not the original image, no query will be performed.

Before the anti-counterfeiting verification, the user also includes the producer or seller scanning the label through a card reader or a device (such as a smart phone) with a camera and fractal analysis software installed to verify whether it is the product it produces or sells.

Among them, the identification code is the unified location assigned by the label association or the government to each label manufacturer, and the global or national unique code of the sub-number is automatically generated by the computer. The identification code is the global or national unique code, which is different in different labels; Graphic code; fractal graphics, the copied and printed ones are visually distinct and can be identified by image recognition software.

Advantages of the present invention:

(1) Identification is unique. The identification code of each label is different. The combination of identification code and fractal graphics is unique. There is no label with the same identification code and fractal graphics.

(2) High security, the information writing area of the label can print encrypted ciphertext according to the needs of customers.

(3) Anti-counterfeiting. The printed fractal graphics are graphics generated by algorithms. The fractal graphics forged by shooting and scanning are images rather than graphics. They are obviously different from printed ones and can be identified by naked eyes and machines. Thereby preventing someone from forging the label.

(4) Anti-harsh environment, the carrier material can choose moisture-resistant, waterproof, heat-resistant and other materials according to the actual requirements of the application environment.

(5) It is widely used and can be applied to the surface of any solid material, including the surface of metal and electrical appliances where RFID tags cannot be applied.

(6) The cost is low, and the material for making the label can be a carrier material that can be written such as plastic or paper, which is much lower than the cost of RFID electronic components.

(7) The network information management and traceability of products can be realized through terminal scanning of product labels and information exchange with network databases. The whole process of product monitoring from factory to logistics to dealers can be achieved.

(8) It is convenient and quick to verify the authenticity. Enter the identification code of the label into the query system of the designated website or use a smart phone with a camera function and Internet access to scan the label and directly log in to the query system of the website for query verification.
