[0004] In summary, there is a need for a new dot code suitable for use as an anti-counterfeiting mark of goods to overcome the above-mentioned shortcomings. SUMMARY

[0043] The application will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the application, but do not limit the application in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the application. These all belong to the protection scope of the application.

[0044] At present, most dot matrix code encoding is positioned by positioning points in fixed positions. This mode is easy to find the positioning points by people, so that the positioning points in the dot matrix code are destroyed, resulting in that the correct information cannot be identified.

[0045] In view of the problems in the prior art, the application provides a dot matrix code generation, decoding and anti-counterfeiting method, which aims to solve the problems that the dot matrix code is easy to be positioned and destroyed, and improve the concealment of the dot matrix code so that it can be used as an anti-counterfeiting label of a product.

[0046] Fig. 1 is a flowchart of a dot matrix code generation, decoding and anti-counterfeiting method provided by an embodiment of the application, as shown in Fig. 1, the method in the embodiment can comprise:

[0047] Step S101, generating dot matrix code.

[0048] In an example embodiment, the dot matrix code comprises: a locating point and a data storage area; wherein the locating point is used to indicate the starting position of the data storage area, and the data storage area is used to store anti-counterfeiting information.

[0049] In an example embodiment, the position of the locating point can be randomly distributed, and the locating point comprises a specified shape composed of three or more points, thereby improving the difficulty of identifying the locating point by the human eye.

[0050] In an example embodiment, the specified shape is composed of three points, for example, the locating point is 110, 010, or 011, 010, or 0110, 0100. The specified shape is composed of four points, for example, the locating point is 0100, 0111. The specified shape is composed of five points, for example, the locating point is 0101, 0111.

[0051] It should be noted that the number of locating points is not limited, and the length of the binary string is not limited.

[0052] In a preferred embodiment, at least two digits 1 in a 2-row matrix composed of two binary strings are located in the same column. Correspondingly, if 1 in the binary string represents a black dot in the dot matrix, and 0 in the binary string represents a white dot in the dot matrix, it is equivalent to setting at least two black dots in the same column in the dot matrix. Such a setting mode can effectively prevent misreading of the locating point and improve the identification accuracy of the locating point.

[0053] In an example embodiment, the points in the locating point are located in multiple rows, and there are staggered rows between at least two of the multiple rows. The multiple rows are different odd rows or are located in different even rows. Data can be stored in multiple groups to improve redundancy, so that even if part of the data is damaged, the correct reading of the data can still be ensured.

[0054] In an example embodiment, the row data is grouped in pairs, and each group contains a locating point.

[0055] It should be noted that in the present embodiment, the multiple consecutive rows refer to multiple rows arranged from top to bottom, for example, the first row, the second row, and the third row are consecutive rows, the second row and the third row are consecutive rows, and so on. In the present embodiment, the staggered rows refer to the interval of one N+1 row between the Nth row and the N+2th row. Similarly, in addition to an interval of one row, an interval of more than one row can also be provided, for example, an interval of two rows, an interval of four rows, and further preferably an interval of any odd number of rows, for example, an interval of three rows, an interval of five rows, and the like.

[0056] The points in the positioning points are located in multiple rows, for example, in the 3rd row, the 4th row, and the 6th row, for example, in the 3rd row, the 4th row, and the 5th row, for example, in the 3rd row, the 5th row, and the 7th row.

[0057] For example, the positioning points in the embodiment can include a specified shape composed of at least three black points, which can identify the direction from left to right. FIG. 2 is a schematic diagram of dot matrix code provided by the embodiment, and FIG. 3 is a schematic diagram of dot matrix code provided by the embodiment. As shown in FIG. 2, the positioning points include three points, the 2nd row and the 4th row in the even rows form a T shape (see the boxed black points), and the 18th row and the 20th row form a T shape; the 5th row and the 7th row in the odd rows form a T shape, and the 17th row and the 19th row form a T shape. As shown in FIG. 3, the positioning points include three points, the 2nd row and the 4th row in the even rows form a shape similar to the number 7 (see the boxed black points), and the 18th row and the 20th row form a shape similar to the number 7; the 5th row and the 7th row in the odd rows form a shape similar to the number 7, and the 17th row and the 19th row form a shape similar to the number 7.

[0058] It should be noted that the embodiment does not limit the number of specific points that constitute the positioning points, and the shapes formed by the points.

[0059] In an optional embodiment, the points in the positioning points are located in different odd rows or different even rows. Specifically, the odd rows or the even rows as a whole can be offset by half the interval to identify the time zone.

[0060] In the embodiment, the data is formed by the rows as a whole, so that the dot matrix code has no regularity in vision and is more concealed, and is not easy to be imitated and damaged.

[0061] In another optional embodiment, the dot matrix code includes multiple positioning points, and the positioning points are alternately distributed in the left and right regions as a whole. Such a setting mode belongs to a redundant design. If the left region is polluted, the positioning points can still be identified from the right region, so that the identification rate of the effective data can be improved.

[0062] For example, in the data storage region, the data is converted into a binary form for encoding and storage, in which: the value 1 is represented by a black point in the dot matrix code, the value 0 is represented by a white point in the dot matrix code, and the points in the dot matrix code maintain a fixed interval in the horizontal direction and the vertical direction.

[0063] In yet another optional embodiment, the effective data appears uniformly and multiple times in the data storage region, wherein the effective data refers to data containing anti-fake information.

[0064] In step S102, the generated dot matrix code is printed according to a preset anti-counterfeiting manner.

[0065] In this embodiment, the dot matrix code can be printed on the carbon-free package by carbon printing, which is not easy to be recognized by naked eyes and is not easy to be copied. Then, the dot matrix code is scanned by a special infrared device to read the data.

[0066] In step S103, after the dot matrix code on the printed matter is recognized and mapped into corresponding numerical values, the dot matrix code is converted into decoding data.

[0067] In this embodiment, the dot matrix code image collected by the camera can be subjected to grayscale processing to obtain a grayscale image. Then, the grayscale image is subjected to contour detection to obtain contour information of each code point in the image. According to the contour information, the position of each code point is determined. Finally, each code point is mapped into binary data according to the position.

[0068] For example, FIG. 4 is a schematic diagram of the principle of decoding the dot matrix code according to an embodiment of the present application. As shown in FIG. 4, the dot matrix code image is scanned by a device including a camera, and then the scanned image is subjected to perspective correction processing to obtain the dot matrix code. The contour of each code point in the dot matrix code is obtained, and is further mapped into numerical values. Finally, the decoding data is obtained.

[0069] In step S104, the decoding data is subjected to legality verification by a server.

[0070] In this embodiment, the decoded data is sent to the server for verification of legality.

[0071] Specifically, the server pre-stores the to-be-encoded data, and the anti-counterfeiting information in the to-be-encoded data is associated with the product identification information. The server queries the anti-counterfeiting information according to the received product identification information, and compares the received anti-counterfeiting information with the locally stored anti-counterfeiting information. If the comparison result is consistent, the dot matrix code is considered to be a genuine product. Otherwise, the dot matrix code is considered to be a counterfeit product.

[0072] In this embodiment, the dot matrix code is generated, the generated dot matrix code is printed according to a preset anti-counterfeiting manner, the dot matrix code on the printed matter is recognized and mapped into corresponding numerical values, and the dot matrix code is converted into decoding data. The decoding data is subjected to legality verification by a server. Thus, the positions of the positioning points in the dot matrix code are not fixed and accumulated, and the randomness is high, so that the dot matrix code is not easy to be recognized by artificial recognition, and the threshold for imitation is indirectly improved. When the positions of the positioning points cannot be accurately recognized, the region for storing data is effectively protected, so that the dot matrix code can be widely used as a product anti-counterfeiting label.

[0073] The present application also provides an anti-counterfeiting label, which comprises a dot matrix code. The dot matrix code is recognized and mapped into corresponding numerical values to be converted into decoding data. The decoding data is subjected to legality verification by a server.

[0074] It should be noted that the anti-counterfeiting mark in the embodiment can be generated by the method shown in Figure 1. The dot matrix code of the anti-counterfeiting mark includes: a positioning point and a data storage area; wherein the positioning point is used to indicate the starting position of the data storage area, and the data storage area is used to store anti-counterfeiting information; the position of the positioning point is randomly distributed, and the positioning point includes a specified shape composed of at least three black points.

[0075] For example, the points in the positioning point are located in multiple rows; there are staggered rows between at least two of the multiple rows; the multiple rows are different odd rows, or are located in different even rows.

[0076] It should be noted that the multiple consecutive rows in the embodiment refer to multiple rows arranged from top to bottom, for example, the second row, the third row, and the fourth row are consecutive rows, the second row and the third row are consecutive rows, and the like. In the embodiment, the staggered rows refer to the interval of one N+1 row between the Nth row and the N+2th row. Similarly, in addition to one row, more than one row can be staggered, for example, two rows, four rows, and further preferably more than one odd row, for example, three rows, five rows, and the like.

[0077] In the embodiment, the dot matrix code includes multiple positioning points, and the positioning points are alternately distributed in a spiral shape as a whole. In the data storage area, the data is converted into a binary form for encoding and storage, wherein: the value 1 is represented by a black point in the dot matrix code, and the value 0 is represented by a white point in the dot matrix code, and the points in the dot matrix code maintain a fixed interval in the horizontal and vertical directions; the effective data uniformly and multiple times appears in the data storage area, wherein the effective data refers to data containing anti-counterfeiting information; and the dot matrix code is printed on a carbon-free package by carbon printing.

[0078] Further, the dot matrix code image captured by the camera can be processed by grayscale processing to obtain a grayscale image; the grayscale image is subjected to contour detection to obtain contour information of each code point in the image; the positions of the code points are determined according to the contour information; the positions of the code points are mapped into binary data; then, the positioning points are searched for; starting from the starting position determined by the positioning points, the data is read in the order of encoding.

[0079] The anti-counterfeiting mark in the embodiment can randomize the positions of the positioning points in the dot matrix code, so that the positions of the positioning points in the dot matrix code are more concealed, the positioning points are not easily identified, the anti-counterfeiting information of the data storage area is effectively protected, and the dot matrix code can be widely used as a product anti-counterfeiting label.
