[0002] With the development of the times, companies and organizations are processing more and more official documents, and efficiency is improving more and more rapidly. Therefore, in order to improve the security of seal use, the industry now generally uses seal control devices to manage the use of seals. A seal control device is an automatic stamping instrument, which is more scientific and standardized than traditional manual stamping. It can separate people from seals to ensure the scientific, safe and efficient use of seals.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0061] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0062] Example 1

[0063] Figure 1 This is a schematic diagram of the seal compartment 1 of a seal device for document encryption provided in Embodiment 1 of the present invention. Figure 2 This is a schematic diagram of the bottom cover 2 of a seal encryptor for document encryption provided in Embodiment 1 of the present invention, as shown below. Figure 1 and Figure 2 As shown, the stamping device for document encryption includes a stamp chamber 1 and a bottom cover 2. The stamp chamber 1 is the component used to stamp the document to be stamped, and the bottom cover 2 is the component used to place the document to be stamped. When in use, the document to be stamped is placed on the bottom cover 2, and then the stamp chamber 1 is used to stamp the document.

[0064] like Figure 1 and Figure 3 As shown, the stamp compartment 1 includes a housing 11, a pressing handle 12, a stamp body 13, an elastic return module 14, a rotation module 15, and a control module 16. The stamp body 13 is rotatably and vertically mounted inside the housing 11. The pressing handle 12 is used to lower the stamp body 13 when pressed. The elastic return module 14 has an elastic return force and is used to provide the pressing handle 12 with the force to return to its initial state. The rotation module 15 is used to drive the stamp body 13 to rotate.

[0065] The stamp body 13 refers to the main component engraved with a stamp pattern for stamping documents. The stamp body 13 is housed within the housing 11, which protects the internal structure and the related circuitry of the stamp compartment 1. The pressing handle 12 is fixedly connected to the upper end of the stamp body 13 via the rotating module 15, allowing the pressing handle 12 to move the stamp body 13 vertically. The elastic return module 14 is a component with elastic restoring force that allows the pressing handle 12 to return to its initial state. In the initial state, there is a certain distance between the stamp body 13 and the lower edge of the housing 11. Therefore, the user can first place the housing 11 in the stamping area of ​​the document to be stamped, and then press the pressing handle 12 to stamp the document.

[0066] Optionally, the elastic return module 14 can be fixedly connected at one end to the housing 11, and at the other end to the pressing handle 12 via the rotating module 15, so that the elastic return force of the elastic return module 14 can drive the pressing handle 12 to return to its initial state. Preferably, the elastic return module 14 includes a spring with good elastic return force.

[0067] The rotation module 15 refers to the module that can drive the seal body 13 to rotate. By setting the rotation module 15, the seal body 13 can be rotated to different angles to stamp the document to be stamped.

[0068] Figure 4 This is a schematic diagram of a stamp document placed on the bottom cover 2 according to Embodiment 1 of the present invention, as shown below. Figure 2 and Figure 4 As shown, the bottom cover 2 is equipped with a position detection module 21 and a document placement area 22. The document placement area 22 is used to place the document to be stamped, and the position detection module 21 is used to detect the position information of the stamp compartment 1. The document placement area 22 refers to the area used to place the document. Since the document to be stamped is usually square, the document placement area 22 is preferably square. The document to be stamped can be partially or entirely located on the document placement area 22. Figure 4Taking a document to be stamped that is larger than the document placement area 22 and partially located within the document placement area 22 as an example. The position detection module 21 is a module used to detect the position of the stamp compartment 1. The position information reflects the location of the stamp compartment 1. During specific detection, different positioning points can be selected on the stamp compartment 1 as needed. The relative position of the positioning point and the coordinate origin set on the base is used as the position information. For example, a point on the central axis of the stamp body 13 can be selected as the positioning point, and the position information reflects the relative position of the positioning point and the coordinate origin set on the bottom cover 2. Preferably, the position detection module 21 includes a position sensor. A position sensor is a sensor that can sense the position of the object being measured and convert it into a usable output signal. It can sense the position of the object being measured and convert it into a usable output signal. By making the position detection module 21 a position sensor, the position information of the stamp compartment 1 can be easily detected.

[0069] like Figure 3 As shown, the control module 16 is communicatively connected to the position detection module 21 and electrically connected to the rotation module 15. The control module 16 is used to acquire position information, determine rotation angle information based on the position information, control the rotation module 15 to drive the seal body 13 to rotate based on the rotation angle information, and store the position information as standard position information and the rotation angle information as standard angle information.

[0070] The control module 16 refers to a module used for logic control, which may include a control circuit, or specifically a programmable chip such as an MCU, DSP, or FPGA. The control module 16 performs logical judgments and processing through programming. The rotation angle information refers to the rotation angle of the seal body 13. The rotation angle information is determined based on the position information, ensuring a correspondence between the rotation angle and position information. When the seal chamber 1 is in different positions, the seal body 13 rotates to different rotation angles to perform the stamping. Simultaneously, the position information is stored as standard position information, and the rotation angle information is stored as standard angle information. Therefore, when determining the authenticity of a stamped document, it is possible not only to judge based on the pattern of the stamp but also based on the position and angle of the stamp on the document.

[0071] The above solution detects the position information of the stamp chamber 1 by setting a position detection module 21 on the base, drives the stamp body 13 to rotate by a rotation module 15, and then obtains the position information through a control module 16. Based on the position information, the rotation angle information is determined, and the rotation angle information is used to control the rotation module 15 to drive the stamp body 13 to rotate. The position information and rotation angle information are stored as standard position information and standard angle information, respectively. Therefore, when judging the authenticity of stamped documents, it is possible not only to determine whether the stamp is correct based on the stamp pattern, but also to determine whether the stamped document is the original stamped document based on the stamp's position and angle. This three-dimensional design greatly enriches the original identification information of the stamped document, making it easier to distinguish. It expands the original method of only focusing on stamp pattern identification to multi-dimensional and multi-information original document identification, solving the problem that existing stamping devices usually just stamp directly on the document, resulting in low accuracy in determining the authenticity of the document later.

[0072] In optional embodiments of the present invention, such as Figure 1 As shown, the rotating module 15 includes a power component 151 and a rotating suction cup 152. The power component 151 provides rotational torque. One end of the power component 151 is fixedly connected to the rotating suction cup 152, and the other end of the rotating suction cup 152 is fixedly connected to the stamp body 13. Since the power component 151 provides rotational torque, it drives the rotating suction cup 152 to rotate when it starts. Because the rotating suction cup 152 is fixedly connected to the stamp body 13, its rotation drives the stamp body 13 to rotate, thus achieving the goal of the power component 151 driving the stamp body 13 to rotate. Preferably, the power component 151 includes a stepper motor. When the stepper motor starts, its output shaft rotates. Therefore, simply fixing the output shaft of the stepper motor to the rotating suction cup 152 is sufficient to drive the rotating suction cup 152 to rotate. In a specific embodiment of the present invention, a stepper motor is fixedly mounted on the pressing handle 12, the output shaft of the stepper motor is fixedly connected to the upper end of the rotating suction cup 152, and the lower end of the rotating suction cup 152 is fixedly connected to the stamp body 13, so that the stamp body 13 can be driven to rotate when the stepper motor is started.

[0073] Based on the above embodiments, the stamp compartment 1 further includes a transmission module 17. The power component 151 is fixedly connected to one end of the rotating suction cup 152 via the transmission module 17, and the other end of the rotating suction cup 152 is fixedly connected to the stamp body 13. The transmission module 17 is used to transmit the rotational torque of the power component 151 to the rotating suction cup 152 to drive the rotating suction cup 152 to rotate the stamp body 13 horizontally. The transmission module 17 is a component capable of transmitting the rotational torque of the power component 151 to the rotating suction cup 152 to make the rotating suction cup 152 rotate horizontally. The transmission module 17 facilitates the horizontal rotation of the rotating suction cup 152. For example, when the power component 151 is placed horizontally, the transmission module 17 may include a pair of vertically meshing gears, thereby transmitting the force of the power component 151 rotating vertically to the rotating suction cup 152, causing the rotating suction cup 152 to rotate horizontally. Consequently, the stamp body 13 also rotates horizontally, resulting only in a change in the angle of the stamp pattern during stamping. Depending on the requirements, the transmission module 17 can also be other components, as long as they can transmit the rotational torque of the power component 151 to the rotating suction cup 152. No specific limitation is made here.

[0074] In optional embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the stamp compartment 1 also includes a first power module 10, which provides power to the control module 16 and the rotation module 15. The first power module 10 is a module capable of providing power; specifically, it can be a battery, thus providing power to the control module 16 and the rotation module 15.

[0075] In an optional embodiment of the present invention, to facilitate the installation of the power component 151, a mounting component is provided between the pressing handle 12 and the transmission module 17. Both the power component 151 and the control module 16 are mounted on the mounting component, thereby facilitating the connection between the control module 16 and the power component 151. Furthermore, when the power component 151 includes a stepper motor, the stamp chamber 1 also includes an encoder. The stepper motor drives the rotating suction cup 152 to rotate via the encoder and the transmission module 17, thereby rotating the stamp body 13 to a specified angle.

[0076] In a specific embodiment of the present invention, such as Figure 1As shown, the elastic recovery module 14 includes two springs, and there are also two first power modules 10. Each first power module 10 includes a battery. The upper end of one spring is fixedly connected to the housing 11, and the lower end is fixedly connected to a battery. The upper end of the other spring is fixedly connected to the housing 11, and the lower end is fixedly connected to another battery. The two batteries are fixedly connected to both ends of the transmission module 17. The upper end of the transmission module 17 is fixedly connected to the power component 151, and the upper end of the power component 151 is fixedly connected to the pressing handle 12, which can be raised and lowered. The lower end of the transmission module 17 is fixedly connected to the upper end of the rotating suction cup 152, and the lower end of the rotating suction cup 152 is fixedly connected to the stamp body 13, which can rotate relative to the housing 11. Thus, when the pressing handle 12 is pressed, the stamp body 13 will also descend accordingly. When the force on the pressing handle 12 disappears, the elastic recovery force of the spring will cause the stamp body 13 to rise back to its initial state. When the power component 151 is activated, it can drive the rotating suction cup 152 to rotate through the transmission module 17, thereby causing the seal body 13 to rotate.

[0077] Based on the above embodiments, such as Figure 1 and Figure 5 As shown, the stamp compartment 1 also includes a first charging contact 101, which is electrically connected to the first power module 10 and used to supply external power to the first power module 10 for charging. The first charging contact 101 can be a charging interface, such as a Type-C interface or a USB interface, so that the first power module 10 can be charged simply by connecting an external power source. Preferably, the first charging contact 101 is located on the housing 11 to facilitate connection to an external power source.

[0078] In optional embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the stamping device also includes a first switch module 18 and a second switch module 19. Pressing the handle 12 to descend to a first height triggers the first switch module 18, causing it to output a first switch signal. Pressing the handle 12 to descend to a second height triggers the second switch module 19, causing it to output a second switch signal. The second height is greater than the first height. The first switch module 18 is the module that can output the first switch signal when triggered; the first switch signal is an electrical signal. The second switch module 19 is the module that can output the second switch signal when triggered; the second switch signal is also an electrical signal. Because the second height is greater than the first height, pressing the handle 12 to descend will first trigger the first switch module 18, and then trigger the second switch module 19. There will be a time difference during the triggering of the first switch module 18 and the second switch module 19. The time difference T = D / V, where D is the difference between the first height and the second height, and V is the speed at which the handle 12 descends.

[0079] The control module 16 is electrically connected to both the first switch module 18 and the second switch module 19. The control module 16 is used to obtain position information when it receives the first switch signal, determine the rotation angle information based on the position information, control the rotation module 15 to drive the seal body 13 to rotate based on the rotation angle information, and store the position information as standard position information and the rotation angle information as standard angle information when it receives the second switch signal.

[0080] Because there is a time difference between triggering the first switch module 18 and the second switch module 19, there is also a time difference between the control module 16 receiving the first switch signal and the second switch signal. The control module 16 will receive the first switch signal first, and then receive the second switch signal. In actual use, when the handle 12 is pressed down, the first switch module 18 is triggered first, and the control module 16 receives the first switch signal. At this time, the control module 16 can obtain the position information, and then determine the rotation angle information based on the position information. Based on the rotation angle information, the rotation module 15 is controlled to drive the stamp body 13 to rotate. Then, pressing the handle 12 to continue to descend will trigger the second switch module 19. At this time, the stamp body 13 has completed the stamping. The control module 16 will receive the second switch signal and then record the current stamp position information and rotation angle information as standard position information and standard angle information, respectively, so that the authenticity of the stamped document can be judged based on the standard position information and standard angle information later. This realizes two-level control, which can first control the rotation of the stamp body 13 based on the position of the stamp chamber 1, and then store the position and angle of the stamp.

[0081] Based on the above embodiment, the pressing handle 12 includes a handle body 121, a first actuating arm 122, and a second actuating arm 123, both of which are fixedly mounted on the handle body 121. Both the first actuating arm 122 and the second actuating arm 123 are vertically arranged, and when the handle body 121 descends, it will cause the first actuating arm 122 and the second actuating arm 123 to descend as well.

[0082] The first switch module 18 includes a first switch contact 181, and a first actuator arm 122 is located above the first switch contact 181. The distance between the first actuator arm 122 and the first switch contact 181 is a first height. Since the first actuator arm 122 is located above the first switch contact 181 and the distance between them is the first height, when the first actuator arm 122 descends to the first height, it will trigger the first switch contact 181, causing the first switch module 18 to issue a first switch signal.

[0083] The second switch module 19 includes a second switch contact 191, and a second actuator arm 123 is located above the second switch contact 191. The distance between the second actuator arm 123 and the second switch contact 191 is a second height. Since the second actuator arm 123 is located above the second switch contact 191 and the distance between them is the second height, when the second actuator arm 123 descends to the second height, it will trigger the second switch contact 191, causing the second switch module 19 to issue a second switch signal.

[0084] With the above scheme, when the handle body 121 descends, the first actuator arm 122 and the second actuator arm 123 will descend simultaneously. When descending to the first height, the first actuator arm 122 will trigger the first switch contact 181 below, causing the first switch module 18 to issue a first switch signal. When descending to the second height, the second actuator arm 123 will trigger the second switch contact 191 below, causing the second switch module 19 to issue a second switch signal, thereby realizing two-level control.

[0085] For example, the first actuator arm 122 has a first inclined surface 1221, and the first switch contact 181 has a first arc surface 1811. The first actuator arm 122 contacts the first arc surface 1811 of the first switch contact 181 through the first inclined surface 1221 to trigger the first switch module 18. When the first actuator arm 122 descends, the first inclined surface 1221 contacts the first arc surface 1811, thereby triggering the first switch contact 181. If the first actuator arm 122 and the first switch contact 181 were of other shapes, the first actuator arm 122 might be blocked by the first switch contact 181 when descending, preventing the first switch contact 181 from being triggered. By setting the first arc surface 1811 and the first inclined surface 1221, the first actuator arm 122 can trigger the first switch contact 181 more effortlessly when descending.

[0086] For example, the second actuator arm 123 has a second inclined surface 1231, and the second switch contact 191 has a second arc surface 1911. The second actuator arm 123 contacts the second arc surface 1911 of the second switch contact 191 through the second inclined surface 1231 to trigger the second switch module 19. When the second actuator arm 123 descends, the second inclined surface 1231 contacts the second arc surface 1911, thereby triggering the second switch contact 191. If the second actuator arm 123 and the second switch contact 191 were of other shapes, the second actuator arm 123 might be blocked by the second switch contact 191 when descending, preventing the second switch contact 191 from being triggered. By setting the second arc surface 1911 and the second inclined surface 1231, the second actuator arm 123 can trigger the second switch contact 191 more effortlessly when descending.

[0087] In an optional embodiment of the present invention, the position information includes coordinate information, and the rotation angle information includes clock angle information; the control module 16 is specifically used for:

[0088] Divide the horizontal axis of the document to be stamped into the first equal part.

[0089] Divide the vertical axis of the document to be stamped into a second division. The first division is one of 12 equal parts or 60 equal parts, and the second division is the other of 12 equal parts or 60 equal parts.

[0090] Based on the first and second divisions, the coordinate information is converted into clock angle information.

[0091] Among them, such as Figure 7 As shown, by dividing the horizontal and vertical axes of the document to be stamped into 12 and 60 equal parts respectively, the document can be divided into 720 equal parts. That is, the 12-part axis is equivalent to dividing it into 12 hours, and the 60-part axis is equivalent to dividing it into 60 minutes. Figure 7 Taking the first division into 12 equal parts and the second division into 60 equal parts as an example, according to the clock conversion rules, the hour indicated by the hour hand and the minute indicated by the minute hand can both be converted into a rotation angle. Therefore, any position of any division on the document to be stamped can be converted into a direction of the clock circle, which is equivalent to dividing the circle into 720 equal parts. So each coordinate can be converted into a clock angle, and the clock angle information is the clock angle corresponding to the coordinate information.

[0092] Using the above method, the clock angle information can be easily determined based on the coordinate information of the seal compartment 1, thereby driving the seal body 13 to rotate to the corresponding angle.

[0093] Based on the above embodiments, the coordinate information includes horizontal coordinate information and vertical coordinate information. The first division is divided into 12 equal parts, and the second division is divided into 60 equal parts. The control module 16 is specifically used for:

[0094] Based on the first and second divisions, the coordinate information is converted into clock angle information using the following formula: θ=(X*30+Y*0.5) / 2.

[0095] Where X represents the horizontal axis information, Y represents the vertical axis information, and θ represents the clock angle information.

[0096] The above method allows for convenient determination of the clock angle information based on coordinate data. For example, when the horizontal coordinate is 10 and the vertical coordinate is 40, the clock angle information can be determined to be 320 degrees. Furthermore, depending on specific needs, clockwise or counterclockwise rotation can be selectively determined, thereby controlling the rotation of the stamp body 13. For instance, when clockwise is determined, if the clock angle information is 320 degrees, the stamp body 13 will rotate 320 degrees clockwise. When counterclockwise is determined, if the clock angle information is 320 degrees, the stamp body 13 will rotate 320 degrees counterclockwise. Since documents requiring stamping are typically rectangular, such as A4 paper, dividing the horizontal axis into 12 equal parts and the vertical axis into 60 equal parts allows for more even division of the document.

[0097] In optional embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the bottom cover 2 is also equipped with an origin fixing component 23, which is used to fix the document to be stamped. The origin fixing component 23 refers to a part that can fix the document to be stamped; specifically, it can be a clip. Simply clamping the corner of the document to be stamped will fix it. Furthermore, the location of the origin fixing component 23 can be the origin of a coordinate system. The position detection module 21 can use this as the origin to determine the position information of the stamp compartment 1.

[0098] In an optional embodiment of the present invention, the bottom cover 2 is further provided with a positioning edge 24, which is used to position the side of the document to be stamped. The positioning edge 24 can be fixed to one side of the bottom cover 2. By positioning the side of the document to be stamped using the positioning edge 24, errors in the recorded position information of the stamp are avoided due to the document being placed off-center, thus improving the accuracy of position information detection and enabling higher accuracy in determining the authenticity of the document later.

[0099] In optional embodiments of the present invention, such as Figure 2 and Figure 5 As shown, the bottom cover 2 is also provided with a communication module 25. The position detection module 21 is electrically connected to the communication module 25. The position detection module 21 is used to wirelessly transmit position information to the control module 16 through the communication module 25. The communication module 25 is a module that enables wireless communication between the position detection module 21 and the control module 16. Preferably, the communication module 25 can be at least one of a Bluetooth module and a WiFi module, thus facilitating wireless communication between the position detection module 21 and the control module 16.

[0100] In an optional embodiment of the present invention, a second power module 26 is further provided on the bottom cover 2. The second power module 26 is electrically connected to the position detection module 21 and is used to supply power to the position detection module 21. The second power module 26 can be a battery or other module capable of providing electrical energy.

[0101] In an optional embodiment of the present invention, the bottom cover 2 is further provided with a second charging contact 27, which is electrically connected to the second power module 26 and is used to supply external power to the second power module 26 for charging. The second charging contact 27 can be a charging interface, such as a Type-C interface or a USB interface, so that the second power module 26 can be charged simply by connecting an external power source.

[0102] Example 2

[0103] Figure 8 This is a schematic diagram of a seal system for document encryption provided in Embodiment 2 of the present invention, as shown below. Figure 8 As shown, the stamp system includes a processing module 3 and a stamping device for document encryption according to any embodiment of the present invention; the processing module 3 is used to communicate with the control module 16 to obtain standard position information and standard angle information.

[0104] The processor can be any general-purpose and / or special-purpose processing component with processing and computing capabilities. Examples of processors include, but are not limited to, central processing units (CPUs), graphics processing units (GPUs), various dedicated artificial intelligence (AI) computing chips, processors running machine learning models and algorithms, digital signal processors (DSPs), and any suitable processor, controller, microcontroller, etc. The processor and control module 16 can communicate in various ways, such as via bus, WiFi, Bluetooth, etc., to easily obtain the standard position and angle information stored in the control module 16, and then determine the authenticity of the seal document based on this information. Therefore, when determining the authenticity of a seal document later, it is possible not only to judge the seal's pattern but also to determine if the document is the original seal document based on the seal's position and angle. This three-dimensional design greatly enriches the original identification information of the seal document, making it easier to distinguish. This expands the original method, which only focused on identifying the seal pattern, to identify original documents with multiple dimensions and more information. This solves the problem that existing seal instruments usually just stamp directly on the document, resulting in low accuracy in determining the authenticity of the document later.

[0105] Example 3

[0106] Figure 9This is a flowchart of a seal document recognition method provided in Embodiment 3 of the present invention, used in a seal system for document encryption in any embodiment of the present invention. This embodiment is applicable to the case of identifying the authenticity of seal documents. The method can be executed by a processing module of a seal system for document encryption, which can be implemented in hardware and / or software. Figure 9 As shown, the seal document recognition method includes:

[0107] S310. Obtain the current seal pattern information of the seal file.

[0108] Among them, the current seal pattern information refers to the detailed information of the seal pattern on the seal document, such as the pattern, color, outline and other information that can represent the characteristics of the seal.

[0109] S320. Obtain the current seal position information of the seal file.

[0110] The current seal position information refers to the specific location of the seal on the seal document. For example, if the horizontal and vertical axes of the seal document are divided into different equal parts, each position in the seal document corresponds to a different horizontal and vertical coordinate. The current specific position of the seal can be determined based on the horizontal and vertical coordinates of its location. Since the area involved by the seal may be large, it will occupy different coordinates in the seal document. Therefore, a specific point on the seal can be selected to represent its specific position. For example, when the seal is circular, the position can be determined based on the coordinates of the center point of the seal. Of course, any point on the seal can also be selected to represent its specific position as needed; this is not a specific limitation but merely an example.

[0111] S330, Obtain the current seal rotation angle information of the seal file.

[0112] The current seal rotation angle information refers to the rotation angle of the seal on the seal document relative to the origin.

[0113] In addition, the current seal pattern information, current seal position information, and current seal rotation angle information of the seal document can be obtained step by step or simultaneously. For example, the seal document can be scanned by image recognition, and the current seal pattern information, current seal position information, and current seal rotation angle information of the seal document can be analyzed at the same time. Alternatively, the current seal pattern information, current seal position information, and current seal rotation angle information of the seal document can be identified sequentially.

[0114] S340. Obtain the standard pattern information, standard position information, and standard angle information of the seal document.

[0115] Among them, standard pattern information refers to the information of the correct seal pattern stored in the seal file during the sealing process; standard position information refers to the information of the correct position of the seal stored in the seal file during the sealing process; and standard angle information refers to the information of the correct rotation angle of the seal stored in the seal file during the sealing process. The standard pattern information, standard position information, and standard angle information of the seal file can be obtained simultaneously or in stages, and no specific limitation is made here.

[0116] S350. Determine the authenticity of the seal document based on the current seal pattern information, current seal position information, current seal rotation angle information, standard pattern information, standard position information, and standard angle information.

[0117] The process involves comparing the current seal pattern information with standard pattern information, the current seal position information with standard position information, and the current seal rotation angle information with standard angle information. If all three match, the stamped document is considered genuine. This allows for convenient verification of the authenticity of stamped documents. This three-dimensional design significantly enriches the original identification information of the stamped document, making it easier to distinguish. It expands the original method, which only focused on seal pattern identification, to multi-dimensional, multi-information original document identification, solving many shortcomings of older technologies. It addresses the issue that existing stamping devices typically only stamp directly on documents, resulting in low accuracy in subsequent document authenticity verification.

[0118] It should be understood that the various forms of processes shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this invention can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this invention can be achieved, and this is not limited herein.

[0119] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
