[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0045] The purpose of the present application is to provide a seal with a physical anti-fake function and a manufacturing method, so as to accurately trace the engraver of the physical seal.

[0046] In order to fully express the characteristics of the engraved seal and determine the engraver of the physical seal, the seal is digitized, and a physical characteristic code is engraved in the interval ring (i.e. in a place where the physical seal is not visible, or by a secondary machine manufacturing method, the essence is to engrave the physical anti-fake code in the invisible part of the seal, only the process flow is different) after the seal content is engraved once, so as to realize the method of determining the engraver of the physical seal.

[0047] In order to make the above-mentioned purposes, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0048] Embodiment one

[0049] The present application provides a seal with a physical anti-fake function, comprising: a seal body; a seal surface of the seal body is provided with a seal working surface, an interval ring and a seal outer ring; the seal working surface, the interval ring and the seal outer ring are sequentially arranged from inside to outside; the seal working surface is printed with seal content; the interval ring is provided with an identity unique code of the seal; the seal outer ring is provided with an anti-fake pattern. The identity unique code and the anti-fake pattern are obtained according to the seal content.

[0050] Embodiment two

[0051] The present application also provides a seal manufacturing method with a physical anti-fake function, which is used to manufacture the seal with a physical anti-fake function in embodiment one. As shown in Figure 2 The method comprises:

[0052] Step 101: Digitizing the seal face to obtain a seal face dot matrix. In a rectangular coordinate system, the seal face is divided into n*n parts to obtain a seal face dot matrix; the position of a dot in the seal face dot matrix is recorded as 1, and the position of a non-dot is recorded as 0. Wherein, n = 1000.

[0053] In practical applications, the physical seal to be engraved is digitally processed in a typesetting system to record data. As shown in the following figure. Figure 3 For example, the position of dot 1 is (Xn+2, Yn+4), and the data is recorded as 0; the position of dot 2 is (Xn+2, Yn+5), and the data is recorded as 1.

[0054] Xn+a, Yn+b are specific coordinate data, and a dot is 0 and a solid dot is 1.

[0055] Step 102: Obtain a preset number of Chinese characters of the seal content as a feature character.

[0056] In the typesetting system, a seal is designed with a security thread, which can be obtained by random line thread, feature character thread, and identity characteristic code, etc. The following lists the method of using “feature character thread” to obtain the actual engraving graph of the seal.

[0057] First, the first five Chinese characters of the seal content in the seal working surface form a “feature character”.

[0058] Step 103: Select the font of the feature character in the computer Chinese character library and determine the size of the feature character to obtain an encrypted character.

[0059] Step 104: Superimpose the encrypted character on the seal face dot matrix to obtain a security thread and generate a first engraving graph. The overlapping part of the encrypted character and the outer ring of the seal in the seal face dot matrix is a security thread. The dots of the security thread in the first engraving graph are recorded as 0. The seal laser engraving machine engraves the dots with a position of 0.

[0060] Figures 4-6 The method of using a feature character is listed to obtain an actual engraving graph (first engraving graph) of a seal with a unique security thread: using the “North Star Shares” character, determine the font in the computer Chinese character library, and set the size of the feature character (character height, character width) to obtain an encrypted character. According to the size of the feature character, superimpose the encrypted character on the seal face dot matrix, as shown in the following figure. Figure 4 Cut out the intersection part of the seal outer ring and the Chinese character, as shown in the following figure. Figure 5 Form an actual engraving graph of a seal with a unique security thread, as shown in the following figure. Figure 6

[0061] Step 105: 16-bit encoding of the feature character, the font of the feature character, and the size of the feature character to determine the identity unique code.​

[0062] The characteristic word is encoded, and the identity code of the seal is calculated.

[0063] The identity code of the seal is represented by a 6-bit hexadecimal number.

[0064] According to the characteristic word data of the "Beixing Shares" Chinese character, the identity code of the seal is calculated as d0d1d2d3d4d5d6d7d8d9+font code+height code+width code=h0h1h2h3h4h5.

[0065] d0d1 represents the encoding of the "Bei" character in the computer Chinese character library.

[0066] d2d3 represents the encoding of the "Ji" character in the computer Chinese character library.

[0067] d4d5 represents the encoding of the "Xing" character in the computer Chinese character library.

[0068] d6d7 represents the encoding of the "Gushi" character in the computer Chinese character library.

[0069] d8d9 represents the encoding of the "Fen" character in the computer Chinese character library.

[0070] The font code is the shape encoding in the computer Chinese character library.

[0071] The height code is the encoding of the overall height of the word in the coordinate system.

[0072] The width code is the encoding of the overall width of the word in the coordinate system.

[0073] The identity code of the seal is h0h1h2h3h4h5.

[0074] Step 106: According to the identity code, the physical anti-fake code image is obtained.

[0075] In practical applications, the identity code is also the physical anti-fake code of the seal.

[0076] The identity code of the seal is the physical anti-fake code h0h1h2h3h4h5.

[0077] According to the physical anti-fake code of the seal, the physical anti-fake code image of the seal is obtained.

[0078] The physical anti-fake code image is designed with a 16-bit pattern (the pattern can be selected). As shown in the following table, the relationship between the physical anti-fake code image and the number is defined. Figure 7

[0079] Figure 7 The physical anti-fake code image in the above table is optional, and the figure number is as follows. Figure 7 ​The graphics in the image are variable, and the graphics number is coded as: 1, 2, 3, 4 and so on.

[0080] For example, when the physical security code h0h1h2h3h4h5=6789AB, and the random pattern number is 3, the physical security code generated for the specific seal is a diamond pattern. The corresponding physical security code is as follows: Figure 8 shown.

[0081] Step 107: Covering the physical anti-counterfeiting code pattern to the set position of the spacer ring of the primary engraving pattern to obtain a secondary engraving pattern.

[0082] Step 108: controlling the laser engraving machine to perform a single engraving on the seal surface according to the single engraving pattern to obtain a single engraved seal.

[0083] Step 109: controlling the laser engraving machine to perform a second engraving on the first engraved seal according to the second engraving pattern, thereby obtaining a seal with a physical anti-counterfeiting function.

[0084] The engraving depths of the first engraving and the second engraving are greater than or equal to a preset depth, which is 0.5 mm.

[0085] Use a laser engraving machine to output with typesetting system Figure 6 The actual engraving drawing of the seal, the outer ring and the spacer ring of the seal (the depth is generally not less than 0.5mm), and the working surface of the seal.

[0086] After the laser engraving machine completes the engraving once, the physical seal is not moved and the typesetting system is used to print the Figure 8 (Specific physical anti-counterfeiting code diagram), covering Figure 6 The upper spacer ring fixed position (set position), such as Figure 9 , forming a secondary engraving Figure 10 As shown, output using the typesetting system Figure 10 , and the seal is engraved for the second time. In the spacer ring position of the first engraving (not visible in the seal text), the physical anti-counterfeiting code is engraved.

[0087] After taking the physical seal out of the seal engraving machine, a seal with a physical unique anti-counterfeiting code is completed, that is, a seal with physical anti-counterfeiting function.

[0088] The typesetting system is not a traditional seal engraving system, but a digital information seal system. Once the seal is digitized, the recorded data, i.e., the dot matrix coordinates, are used to obtain the unique engraving data for the seal. Using the system, the engraved data can be accurately engraved at the specified coordinates.

[0089] After the seal is engraved according to the coordinates, the process of using the seal has both visible and invisible parts. The visible part, as the seal content, has its own encryption method, and here it is simply used to express it, resulting in a physical anti-counterfeiting code. This physical anti-counterfeiting code is engraved at the invisible coordinates of the seal. In other words, the seal is given an invisible digital seal identifier, i.e., a physical seal identification mark.

[0090] By using system recognition, as long as the physical seal image is input into the system, the system will generate seal data and calculate whether the physical seal was engraved by the person or not.

[0091] The key points of this invention are: 1. digitizing traditional seals to make them suitable for computer recognition and processing; 2. using specific pattern data to engrave on the seal, giving it a unique data identifier, which is an excellent method for tracing the physical seal, thereby accurately tracing the physical seal engraver.

[0092] By using the method of the present invention, a mobile phone camera function can be used to take a photo and send it to the system, so that the seal engraving department can be identified, thereby providing the society with a convenient service of timely verifying the origin of physical seals.

[0093] In the above method, the typesetting system compiles the entire seal content at once, generating two images. Using the same machine, the typesetting system first outputs one image, engraving the visible portion of the seal. The second output, however, retains the original seal position and engraves the invisible portion. This completes the engraving of a system-recognizable, physically anti-counterfeiting seal.

[0094] The present invention also provides a secondary machine manufacturing method:

[0095] Step 1: Same as steps 101-104 of the secondary image production method, but the resulting engraved image will be Figure 6 and Figure 10 To synthesize, split, and divide into two parts, e.g. Figure 11 and Figure 12 .

[0096] Step 2: Use a more sophisticated laser engraving machine to engrave Figure 11 The semi-finished product with physical anti-counterfeiting function is produced. The typesetting system also outputs the physical anti-counterfeiting code of the semi-finished stamp, such as: h0h1h2h3h4h5 (6-digit hexadecimal number).

[0097] Step 3: Use a laser engraving machine to engrave the seal, and place the semi-finished product produced in the second step of the secondary machine production method on the machine with a positioning fixture, and the typesetting system outputs Figure 12 , engrave the content, and finally engrave it into a seal with physical anti-counterfeiting function.

[0098] Step 4: In the system, the seal data engraved in the above step is associated with the physical anti-fake code of the seal semi-finished product, such as Figure 13 .

[0099] Physical anti-fake code = h0h1h2h3h4h5 (6-bit 16 hexadecimal number), figure number = 3.

[0100] Step 5: Finally, a system-identifiable seal with physical anti-fake function is completed in the layout system.

The above description of the embodiments is only used to help understand the method of the present application and its core idea; meanwhile, for the general technical personnel in the field, the specific implementation manners and application ranges will be changed according to the idea of the present application. In conclusion, the content of the specification should not be understood as the limitation of the present application.
