Those skilled in the art can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0058] Please refer to Figures 1 to 6. An embodiment of the present application provides a ring code 100 used in an electronic seal or digital seal, the content of which corresponds to the electronic document having the electronic seal or digital seal, and the content of different electronic documents corresponds to different ring codes. The ring code 100 includes an anti-counterfeiting code 101 and a ring encryption area 102, and the anti-counterfeiting code 101 fills the ring encryption area 102.

[0059] The anti-counterfeiting code of the embodiment of the present application is filled around the ring encryption area, circling 360 degrees, uniform and beautiful, and the overall visual effect is more unified with the traditional seal, making the ring code more secure and difficult to decipher.

[0060] Specifically, the shape of the electronic seal or digital seal or the ring code in the embodiments of the present application can be circular, oval, square, rectangular or triangular, and providing seals of different shapes increases the variety of seal uses.

[0061] Specifically, electronic seals or digital seals can also be applied to electronic products such as PC terminals, smartphones, mobile terminals, handheld printing devices, tablets, and in-vehicle computers, and the electronic seals or digital seals can be displayed through the displays of the above terminals, making the use of electronic seals and digital seals more convenient.

[0062] Specifically, the ring code may be a ring code of a single encryption graphic, a mixed code combining two types of encryption graphics, or a code combining multiple types of encryption graphics. The embodiments of the present invention do not limit the number of encryption graphics, as long as the encryption graphics can be identified and the corresponding anti-counterfeit code can be identified. The embodiments of the present application form the anti-counterfeit code through the encryption graphics, making the anti-counterfeit code more beautiful and increasing the recognizability of the ring code.

[0063] Specifically, the ring code used in the electronic or digital seal provided by the embodiments of the present application may be a barcode, or a bar-mix code that combines a barcode with one or more other encrypted graphics, or any other encrypted graphic form and identifiable anti-counterfeit code. The embodiments of the present invention facilitate the identification and authentication of the ring code through the barcode, making the ring code structure simpler and easier to identify.

[0064] Specifically, the Barmix code is formed by combining a barcode and a two-dimensional code. The Barmix code in the embodiment of the present application is formed by combining a barcode and a two-dimensional code, which increases the variety of barcodes, allows different information to be expressed using a ring code, and enhances the universality of the ring code. The anti-counterfeit code is formed after the head and tail of the barcode or Barmix code are joined, and the head of the code is a start code and the tail of the code is an end code.

[0065] Specifically, the anti-counterfeit code is a code93 barcode. The code head and code tail of the code93 barcode are joined to form the anti-counterfeit code, with the code head being a start code 300 and the code tail being an end code. The anti-counterfeit code is formed by removing the start code and end code from the barcode of the code93 standard and then joining the start and end. The anti-counterfeit code is a code93 barcode, Or it is a code93 barcode and a code93 barmix code consisting of one or more other encrypted graphics. The code head and code tail of the code93 barcode or code93 barmix code are joined to form the anti-counterfeit code, the code head being a start code and the code tail being an end code. The anti-counterfeit code is formed by removing the start code and the end code from the code93 standard barcode or code93 barmix code and then joining the start and end codes.

[0066] In the limited space of the ring encryption area, removing the "start and end positions" increases the amount of data that can be stored in the improved ring encryption area.

[0067] Specifically, it further includes an indicator code for indicating the start position of the anti-counterfeiting code. The indicator code may be a Chinese character or a graphic. The indicator code may be a number, a Chinese character, or a character or letter in another language. The number, Chinese character, or a character or letter in another language is the name of the department to which the seal belongs, and the connecting line between any pixel point of any character in the department name and the geometric center of the ring encryption area is the starting line, and the intersection point of the starting line and the ring encryption area is the starting point. The electronic or digital seal includes, but is not limited to, seals of party committees, government agencies, the military, diplomacy, finance, social organizations, and academic research institutes, seals of various types of enterprises and entities, various types of administrative review and approval seals, seals dedicated to receipts and financial bills, and personal seals.

[0068] Specifically, the starting position is set based on an element within the barcode, making identification easier and improving the speed at which the ring code is identified.

[0069] Specifically, the kanji character is used as the department name, the connecting line between any pixel point in any character in the department name and the geometric center of the ring encryption area is used as the starting line, and the intersection point of the starting line and the ring encryption area is used as the starting position 200.

[0070] Specifically, the start position is set based on the structure and components within the barcode, making identification easier and improving the speed of identifying the ring code.

[0071] Specifically, the indicator symbol is a graphic, including, but not limited to, a five-pointed star located in the center of the seal, a party emblem, or a national emblem. The graphic is a five-pointed star, and the starting line is a line connecting one of the corners of the star to the geometric center of the ring encryption area, and the intersection of the starting line and the ring encryption area is the starting position.

[0072] Specifically, at least one anti-counterfeit code is set.

[0073] As shown in Figure 4, the same ring code is placed multiple times on the circumference of one circle in the ring encryption area, and each ring code can independently decode the same data. In this way, even if the seal is damaged or destroyed, or the paper carrying the physical seal is torn, the ring code information can still be identified, thereby increasing security.

[0074] Specifically, the ring encryption area includes at least one closed loop, and the anti-counterfeit code is disposed inside or outside the closed loop.

[0075] As shown in Figure 5, the ring encryption area may have an outer frame but not an inner frame. Without an inner frame, interference during code scanning can be reduced, and the speed and recognition rate of code scanning can be improved.

[0076] As shown in FIG. 6, the ring encryption area does not need to have an outer frame. If there is no outer frame, interference during code scanning can be reduced, and the speed and recognition rate of code scanning can be improved.

[0077] The ring encryption area may or may not have an outer frame. If it does not have an outer frame, it will reduce interference when scanning the code and improve the speed and recognition rate when scanning the code.

[0078] Specifically, an embodiment of the present application provides a ring code used in a real seal, which is the ring code described above.

[0079] The ring code used in the physical seal provided by the embodiment of the present application facilitates the authentication and identification of the ring code, and the structure of the ring code is simpler, making it easier to identify.

[0080] Another aspect of the present application provides an encoding method, as shown in FIG. 7, comprising: Step S10: acquiring data to be encoded and converting the data to be encoded into a forgery prevention code; and S11, filling the ring encryption area with the anti-counterfeit code.

[0081] Specifically, after the data to be encoded is converted into a forgery prevention code, the start code and end code are removed.

[0082] Specifically, the anti-counterfeit code is filled into the ring encryption area by: At least one of the anti-counterfeiting codes is filled into the ring encryption area, the ring encryption area includes at least one closed ring, and the anti-counterfeiting code is disposed inside or outside the closed ring.

[0083] Specifically, as shown in FIG. 8, an embodiment of the present application provides a method for identifying a ring code, Step S30: randomly dividing the ring code into a barcode shape from an arbitrary position and expanding it; Step S31: Dividing the barcode into two segments according to the positions of the start and end codes of the barcode; Step S32 of recombining the two segments to form a barcode format beginning with a start symbol and ending with an end symbol; and step S33 of scanning, analyzing and acquiring data.

[0084] Specifically, embodiments of the present invention encode data using barcodes to form ring codes, and then use cut and splice to improve the speed of barcode identification.

[0085] Specifically, an embodiment of the present application provides a method for identifying a ring code, as shown in FIG. 9, the method includes: Step S20: obtaining the start position of the anti-counterfeit code; Step S21: dividing and expanding the counterfeit prevention code from a starting position to form a barcode; and step S22 of scanning the barcode to obtain the encoded data.

[0086] Specifically, as shown in FIG. 10, the start position of the anti-counterfeit code is obtained as follows: S40: acquiring an arbitrary pixel point of an arbitrary character in the name of the department to which the seal belongs and the geometric center of the ring encryption area; Step S41: connecting an arbitrary pixel point in an arbitrary character of the department name with the geometric center of the ring encryption area to set the starting line; and step S42 of obtaining the intersection position of the start line and the ring encryption area.

[0087] Specifically, as shown in FIG. 11, the start position of the anti-counterfeit code is obtained as follows: Step S50: obtaining any specific pixel point of the ring code internal figure and the geometric center of the ring encryption area; Step S51: connecting the location of the pixel and the geometric center of the ring encryption area to form a starting line; and step S52 of acquiring the intersection position of the start line and the ring encryption area.

[0088] Specifically, the internal figure is a five-pointed star, the specific pixel point is the location of any corner of the five-pointed star, and the location of any corner of the five-pointed star and the geometric center of the ring encryption area are connected to form a starting line.

[0089] An embodiment of the present application provides a stamp, which includes a stamp base and a stamp face, and the stamp face is provided with the ring code described above.

[0090] Specifically, the ring code in the embodiment of the present application can be formed by making one revolution based on the barcode of the Code 93 standard. The ring code is also classified into "start code---data area---check code (two check codes, C and K)---end code" based on the Code 93 standard.

[0091] Specifically, if the barcode is deformed around the ring encryption area and the beginning and end are joined, it is difficult to find the starting position of the barcode. However, the Code93 barcode has a fixed starting point, so after encrypting the seal using the Code93 barcode, the barcode can be restored through the fixed feature. By using Code93, the ring code can achieve anti-counterfeiting protection for the seal with just one encryption area. The beginning and end of the ring code can be joined to improve its appearance.

[0092] Specifically, the process of identifying a ring code is the inverse of the encoding process and is further described below.

[0093] As shown in FIG. 13, after scanning the code, randomly dividing and expanding the barcode into barcode shapes of any two segments from any position; Dividing the barcode into two segments according to the positions of the start and end codes of the barcode, as shown in Figure 14a and Figure 14b; recombining the two segments to form a standard barcode format, as shown in FIG. 15; scanning, analyzing and acquiring data.

[0094] It should be understood that the present embodiment can also directly identify the start position, i.e., the position of the start code and end code, and separate them from the start position.

[0095] Specifically, in actual application, the barcode uses the start and end positions in the Code93 standard to determine the start position of the 2D code. In the Code93 standard, the start and end codes are "11141" and "11141" respectively, which means that each contains the number "4". These two positions have particularly thick barcodes, which not only looks bad, but also makes them difficult to dry when used to print physical seals. They are also prone to getting on hands or other papers, making the barcode unreadable. However, according to the Code93 rules, there are only two widths of black barcodes in the "data area", namely "1" and "2". Although a black barcode with a width of "3" may appear accidentally in the check code, the probability of this occurring is not high. Therefore, after removing the barcodes with a width of "4" at the start and end positions, most of the remaining black barcodes have a width of "1" or "2". The black barcodes are delicate and neat, which greatly improves the visual effect. Also, with limited spatial location in the seal ring region, removing the start and end locations increases the amount of data stored in the improved ring code.

[0096] After canceling the start position / end position, it is necessary to re-acquire the start position and identify the code. It should be understood that in the embodiment of the present application, the start position is determined using the orientation of the tip of the five-pointed star in the center of the seal. The specific identification method is as follows: 1. Identifying the vertical direction of the seal based on the layout position of the characters in the seal; 2. Identify the center position of the seal and the relative positions of the five pointed corners of the five-pointed star and the vertical direction based on the vertical direction of the seal; 3. Select a sharp corner (for example, the sharp corner where the center of the seal is connected to the tip of the five-pointed star and overlaps with the vertical direction of the seal), and connect the sharp corner to the center of the seal to form a straight line; 4. Obtaining the intersection position between the straight line and the seal external barcode; 5. Using the intersection position as a starting data position, the ring code is divided and expanded to form a barcode pattern; 6. Scan the barcode pattern to obtain the data. In this step, if decoding is performed using the conventional Code93, the start and end positions must be added to the expanded barcode to form a complete Code93 barcode, which must then be scanned. Of course, the Code93 decoding method can be modified appropriately to directly scan the expanded barcode to obtain the data.

[0097] Of course, data can be obtained in other ways, for example, by connecting the center of the seal to a specific position of a specific character on the seal to indicate the start position of the ring code.

[0098] The specific position of a particular Chinese character may be the position of the rightmost pixel of the last character, or the position of the leftmost pixel of the first character, or the position of the rightmost pixel of the third Chinese character, etc.

[0099] For example, (1) when generating a seal, a center portion is generated that does not include the surrounding ring code, and the center portion includes a central five-pointed star and the company name surrounding the arc of the five-pointed star. (2) A line is connected between the center of the seal and the rightmost pixel of the last Chinese character in the company name. (3) The intersection point of the connecting line and the ring code is set as the start position of the ring code. (4) A ring code is generated according to the start position.

[0100] Specifically, the same ring code is placed multiple times on the circumference of one circle in the ring encryption area, and each ring code can independently decode the same data. In this way, it is possible to identify the ring code information even if the seal is damaged or destroyed, or the paper carrying the physical seal is torn.

[0101] When generating or decoding such an "arc segment" type ring code, the start position of the ring code can be determined by bending the Code93 standard barcode to form a ring code, as in the above-mentioned Examples 1 and 2, or by removing the start / end positions of the Code93 barcode and using the orientation of the pointed corners of a five-pointed star or the orientation of a specific position of a specific Chinese character in a seal.

[0102] Each of the ring codes may or may not have an outer frame. If the ring code does not have an outer frame, interference during code scanning can be reduced, and the speed and recognition rate of code scanning can be improved.

[0103] The ring code in the embodiments of the present application may be a seal pattern encrypted by a barcode, and may be stored in the storage medium of a device such as a personal computer, a notebook computer, a mobile device, or a mobile phone.

[0104] It can also be used for electronic seals. Generally, when a document with an electronic signature is printed on a paper document, it is difficult to verify its authenticity. Therefore, by signing a PDF document or other document using an encrypted barcoded seal, the signed document can be printed on a paper document, and the pattern can be captured using a mobile phone, tablet, or other camera-equipped device. The barcode can then be decoded and the original electronic document can be retrieved and compared, verifying the signature on the electronic document and determining its authenticity.

[0105] The electronic seal described above can directly output a seal pattern with a barcode encrypted by a dedicated smart seal onto a paper document.

[0106] Specifically, an embodiment of the present application provides a seal, and the ring code is provided on the seal surface of the seal.
