Abstract

A two-dimensional bar code-based anti-counterfeiting method, a label, and a method for manufacturing the label. A two-dimensional bar code (11) and a graphic (12) are integrated for anti-counterfeiting; this prevents the problem of cracking by an unscrupulous person using brute-force attack via a digital code. A second printing carrier is used to obscure the graphic (12); this prevents the problem of the graphic (12) being directly visible to and scanned by the unscrupulous person. The presence or absence of a demarcation line between the first printing carrier and the second printing carrier allows for the distinction of a computer-generated two-dimensional bar code image from a two-dimensional image read by an image-reading device; this prevents the problem of a two-dimensional bar code database being cracked by the unscrupulous person via brute-force attack. Because the second printing carrier is affixed randomly onto the first printing carrier, and information of relative positions of the demarcation line between the first printing carrier and the second printing carrier and of the two-dimensional image is stored in data, consistency of the position of the demarcation line can be analyzed and determined; this prevents the unscrupulous person from manufacturing a counterfeit label by imitating the manufacturing process of the label.

Description

Method, label and label making method based on two-dimensional code anti-counterfeiting

[Technical Field]

The invention relates to an anti-counterfeiting method, a label and a label manufacturing method, in particular to a method, a label and a label making method based on two-dimensional code anti-counterfeiting.

【Background technique】

Anti-counterfeiting is to solve a problem that is not easy to forge and easy to identify. The purpose of anti-counterfeiting is mainly to distinguish products of different merchants. Before the development of computer, network and 3C technology, the anti-counterfeiting method is mainly for consumers to realize the identification of authenticity directly through the naked eye without tools. The principle of this anti-counterfeiting technology is to make anti-counterfeiting marks with special printing technology, such as Holographic anti-counterfeiting, because this printing technology is difficult, especially the template is difficult to plagiarize, so the anti-counterfeiting cost is very high. It is difficult to know the template through reverse engineering after printing, so the anti-counterfeiting is still very high, but it is because of its template. It is difficult to stop, and the printing cost is high. Therefore, it is difficult to print different holograms for each product. The same hologram will be printed on a large number of products, so if it can crack the template, it will be damaged by counterfeiting. It will be very huge.

With the continuous development of technology, it is difficult to directly distinguish the authenticity by the naked eye, so special equipment is needed. This kind of anti-counterfeiting is a special mark made by special equipment and technology, such as laser anti-counterfeiting code and recessive ink anti-counterfeiting. , anti-counterfeiting, anti-counterfeiting, etc., because this kind of anti-counterfeiting features are difficult to identify with the naked eye, it is necessary to use a special inspection instrument to distinguish the authenticity, so its applicability is not wide, it can only be used for the anti-counterfeiting of valuables.

With the development of computers, the Internet and 3C technology, people began to use the remote server to identify the authenticity, such as password anti-counterfeiting technology, which is to compile a set of digital random passwords for the product, print the password on the logo and cover it. The password is stored in a computer database that can be queried by the consumer. After the product is purchased, the consumer tears the password on the identifier by phone, fax or the Internet for comparison and identification. The same is true, the difference is false, and this A password is obtained through a complex operation. It is difficult to calculate the algorithm after the password 4, and it is difficult to know all the other correct passwords through a password, which has certain anti-counterfeiting. However, since a series of numbers can be solved by a computer program exhaustive algorithm, its anti-counterfeiting is not high.

In order to prevent criminals from cracking digital passwords through computer program exhaustive methods, two-dimensional code anti-counterfeiting technology has been introduced. It is to record data symbol information in a black and white pattern distributed in a plane (two-dimensional direction) by a certain geometric pattern according to a certain rule; skillfully use "0", "1" which constitutes the internal logic foundation of the computer in code preparation. "The concept of bit stream, using several geometric shapes corresponding to binary to represent literal numerical information, automatic reading by image input device or photoelectric scanning device to achieve automatic information processing: 2D barcode / QR code can be in landscape The information is expressed simultaneously with both longitudinal directions, so that a large amount of information can be expressed in a small area. Therefore, the QR code can not only identify each item but also perform anti-counterfeiting. Although the two-dimensional code is more difficult to crack by computer programs than the digital code, the two-dimensional code is actually a digital code consisting of "0" and "1", or can be solved by the exhaustive method of computer programs. The criminals can still scan the QR code and then print it out for counterfeiting, so its security is not particularly high.

In order to prevent the graphics from being copied and printed, a method of anti-counterfeiting through texture is conceived, mainly to change the anti-counterfeiting feature of the anti-counterfeiting printing of the electronic code into a structural texture inherent to the non-human-made marking material, which is to intentionally manufacture the fiber-optic structure. The graphics on the paper are scanned and stored in a database that can be queried, and then the anti-counterfeiting mark is divided into 12 small squares. The consumption is used to query the 12 small squares for the presence or absence of fibers or cores to identify the true and false. Although the method prevents the illegal elements from copying the graphics, the query procedure is also complicated, the comparison is very complicated, the consumer query rate is also very low, and a large number of identifiers are not queried, which means that no anti-counterfeiting is used.

Summarizing the existing anti-counterfeiting technology, the inventor believes that a good anti-counterfeiting technology must have the following elements:

1. The consumer is easy to identify, without the aid of tools, or with the help of a single tool; 2. The consumer can easily obtain the real information and compare it with the product in his hand; 3. The logo is easy to print and easy to make, so Production cost is low; 4. The production technology of the logo cannot be obtained by using the reverse engineering principle of the logo itself; 5. The identification of each product is different, so the cost of copying the illegal elements will be 4艮.

However, the existing anti-counterfeiting technologies cannot all meet the above requirements, so the security of their anti-counterfeiting. Not high.

The beneficial technical effects of the present invention are:

Combining the two-dimensional code with the graphic text for anti-counterfeiting, avoiding the problem that the criminals use the digital code to perform the exhaustive method. If the criminals crack the QR code, they need to print the graphic on the product. Adding the cost of counterfeiting is more secure than using only two-dimensional code for anti-counterfeiting. If the graphic and the two-dimensional code are directly printed on the product, the criminals can scan and print the genuine graphic and two-dimensional code for a small amount of counterfeiting, so the second printing carrier is used to cover the graphic, avoiding the The problem that the criminal molecule can directly see and scan the graphic, and since the two-dimensional code is simultaneously printed on the first print carrier and the second print carrier, when the criminal molecule tears the second print carrier to view the cover under the second print carrier After the graphic, it is difficult to restore the second printing carrier, which increases the cost of illegal imitation.

Since the first print carrier and the second print carrier are not on the same plane, the boundary line can be read by the image reading device, and the computer-generated two-dimensional code image and image reading device can be distinguished by the presence or absence of the boundary line. The two-dimensional code image is read, thereby avoiding the problem that the illegal molecules generate the two-dimensional code image by the computer, and the problem that the criminals can crack the two-dimensional code database by the exhaustive method can be prevented, and the security of the present invention is improved.

By randomly bonding the second print carrier to the first print carrier, and storing the positional information of the boundary between the first print carrier and the second print carrier and the two-dimensional code image in the data, and analyzing and determining the boundary line Whether the positions are the same, this can prevent the criminals from making fake labels by imitating the label making process.

By punching holes in the image area, and the position of the holes is randomly changed, if the criminals want to imitate both the position of the holes and the precise positioning of the holes by the machine, the cost of counterfeiting is increased, and the safety is further improved. .

The various advantages of the anti-counterfeiting technology of the present invention are integrated: 1. The consumer can easily recognize the anti-counterfeiting query by using ordinary tools (such as a mobile phone); 2.

【detailed description】

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in FIG. 1, a two-dimensional code-based anti-counterfeit label includes a two-dimensional code 11 and a graphic 12 printed on the outer package 10 of the product (which can also be printed on the outer casing of the product). The text 12 is located at the periphery of the two-dimensional code 11. In the specific embodiment, the graphic 12 is a bird (which may also be a logo of other animal graphics or products, etc.), and is located above the two-dimensional code 11.

The two-dimensional code 11 and the graphic 12 are in a corresponding relationship in a database of the server, and the graphic 12 has a specific encoding in the database, and the specific encoding is associated with the two-dimensional code through a special algorithm. .

When the security label is produced, the two-dimensional code 11 and the graphic 12 in a one-to-one correspondence in the database are simultaneously printed on the outer package of the product. The two-dimensional code 11 and the graphic 12 are bound in advance in the server.

When the consumer performs the anti-counterfeiting identification, the image reading device (such as a camera or a scanner) is used to read the two-dimensional code, and the two-dimensional code is sent to the server on the network side by wire or wirelessly, and the server acquires the image. Reading the two-dimensional code information read by the device, determining whether the two-dimensional code information read by the image reading device is consistent with the two-dimensional code information stored in the database; if consistent, finding the opposite of the two-dimensional code information The graphic is displayed on the display device (such as the screen of the display or the mobile phone); at this time, the consumer compares the graphic image on the product with the displayed graphic image. If the two images are consistent, it indicates that the product is genuine. If the two images are inconsistent, it indicates that the product is a fake. The combination of the two-dimensional code and the graphic text for anti-counterfeiting avoids the problem that the criminals use the digital code to perform the exhaustive method. However, if the graphic and the two-dimensional code are directly printed on the product, the criminal can also take the genuine map. The text and the QR code are scanned and printed for a small amount of counterfeiting, and the illegal elements can also continuously test the correct two-dimensional code by using the exhaustive method, and the graphic corresponding to the two-dimensional code is downloaded and printed on the outside of the product. On the box.

Example 2

The present embodiment proposes a new two-dimensional code anti-counterfeit label for the shortcomings of the above embodiments. As shown in FIG. 2, the graphic 12 in the label is printed on the outer package 10, and the second The center portion of the dimension code 11 is printed on the paper strip 13 pasted on the outer package, and the peripheral portion of the two-dimensional code 11 is printed on the outer package 10, and the center of the peripheral portion of the two-dimensional code 11 is a figure. The paper strip 13 is covered on the graphic 12, and the graphic 12 is covered. The paper strip 13 is a fragile sticker and is adhered to the outer package 10.

There is a boundary line 131 between the paper strip 13 and the outer package 10, and the paper strip 13 is randomly adhered to the outer package 10, so the relative position of the boundary line in the two-dimensional code image is randomly changed. The relative position information of the boundary line in the two-dimensional code image is stored in the middle database of the server corresponding to the two-dimensional code, and the two-dimensional code 11 and the graphic text 12 also have a corresponding relationship in the database of the server.

Since the two-dimensional code 11 is printed on two print carriers on different planes, and two different print carriers have a boundary line, it can be judged by the presence or absence of the boundary line that the two-dimensional code is printed on two different prints. On the carrier, it is still on the same printed carrier, which can prevent the illegal molecules from synthesizing the two-dimensional code through software and then performing exhaustive methods to try to verify. If the criminal wants to pass the verification, the two-dimensional code must be printed on two print carriers, and then the two-dimensional code is read by the image reading device, and then the verification is performed, which undoubtedly adds a huge cost to the counterfeiter.

As shown in FIG. 3, the method for making the anti-counterfeit label is as follows:

S1: Printing graphic 12 on the outer box of the product;

S2: the paper strip 13 is randomly attached to the outer package 10 and covers the graphic 12; S3: printing a two-dimensional code 11 corresponding to the graphic 12 in the area where the paper strip 13 is pasted;

S4: Reading the two-dimensional code printed on the paper strip 13 and the outer package 10 by using a two-dimensional code reading device

11;

S5: Obtain the position information of the paper strip 13 in the two-dimensional code 11 and the outer box 10 boundary line 131, and store the position information in the database corresponding to the two-dimensional code 11.

When the consumer performs anti-counterfeiting identification, the consumer first reads the two-dimensional code printed on the paper strip and the outer packaging box by using an image reading device (such as a camera or a scanner), and the two-dimensional code is wired or wireless. The method is sent to a server on the network side, the server acquires the two-dimensional code image, and analyzes whether the two-dimensional code read by the image reading device includes a boundary line between the paper strip and the outer package, and if not, passes the The display device informs the consumer that the two-dimensional code is invalid; if yes, further determines whether the two-dimensional code information read by the image reading device is consistent with the two-dimensional code information stored in the database, and if not, the consumption is notified by the display device. The two-dimensional code is illegal; if there is a match, the boundary position information in the two-dimensional code read by the image reading device is compared with the position information of the boundary line stored in the database; if they are consistent, The two-dimensional code information is opposite to the graphic, and the graphic is displayed on the display device. At this time, the consumer identifies the graphic on the product. Displayed graphic comparison, if the two graphic consistent, it indicates that the product is genuine, if the two are inconsistent graphic, it indicates that the item is counterfeit goods. If they are inconsistent, the display device notifies the consumer that the two-dimensional code is invalid.

Since the paper strip is randomly adhered to the outer package, and the relative position information of the boundary between the first print carrier and the second print carrier and the two-dimensional code image is stored in the data, and the position of the boundary is analyzed and determined. Consistently, this prevents the criminals from making fake labels by mimicking the label making process. In other words, the above embodiments are only intended to illustrate the technical solutions of the present invention, and the present invention is not limited thereto. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or equivalent. The spirit and scope of the present invention should be construed as being included in the scope of the appended claims.
