Description

Technical Field

[0001] This utility model relates to the field of document anti-counterfeiting feature recognition, and in particular to a device for cloud-based collaborative document anti-counterfeiting feature recognition. Background Technology

[0002] In recent years, with increasingly frequent global personnel exchanges, business interactions, and tourism activities, the number of people entering and leaving the country has exploded. Border inspection departments are facing significantly increased pressure to control illegal entry and exit, making passport authentication a crucial link in ensuring border security. Passports typically integrate multiple anti-counterfeiting features, which border inspection personnel must use to determine passport authenticity. However, traditional authentication methods have significant limitations: during manual authentication, staff must rely on visual inspection or simple tools to check each feature individually, requiring extremely high levels of professional experience and time-consuming per passport. In high-traffic scenarios, this can easily lead to queues and congestion, making it difficult to meet demand.

[0003] Meanwhile, existing passport verification methods lack efficient technical support: although some stand-alone verification devices can assist in collecting anti-counterfeiting features, they mostly rely on locally stored standard anti-counterfeiting information and cannot synchronize the anti-counterfeiting features of passports from different countries in real time (for example, after a country adjusts its anti-counterfeiting features, the device needs to manually upgrade the database, which is highly lagging); moreover, the core structure of the device is rudimentary, and it only collects features through simple components, lacking the ability to coordinate with the backend system, and thus cannot provide accurate and stable technical support for border inspection work.

[0004] Therefore, there is a need to provide a device based on cloud-based collaborative document anti-counterfeiting feature recognition to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a device for cloud-based collaborative document anti-counterfeiting feature recognition, which solves the problems of unreasonable structural design and unreasonable distribution of various components in existing cloud-based collaborative document anti-counterfeiting feature recognition devices.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a device for cloud-based collaborative identification of anti-counterfeiting features of documents, which includes a data acquisition terminal and a server, wherein the data acquisition terminal is connected to the server; The data acquisition terminal includes: The outer casing is provided with a collection port; A camera, housed within the housing, is positioned facing the acquisition port; and The controller is located inside the housing. The controller is used to send the anti-counterfeiting information of the certificate collected by the camera to the server. The server stores standard anti-counterfeiting information and is used to compare the collected anti-counterfeiting information with the standard anti-counterfeiting information, and send the comparison result to the collection terminal.

[0007] In this invention, the collection port is located at the bottom of the outer casing, and a display screen is provided at the top of the outer casing. The display screen is electrically connected to the controller and is used to display the comparison results.

[0008] In this invention, the outer shell surface is provided with a hand grip with anti-slip texture.

[0009] In this invention, the acquisition terminal further includes a counterfeit detection light source, which is disposed inside the housing and includes at least two of infrared light sources, ultraviolet light sources, and visible light sources, used to illuminate the document to display different types of anti-counterfeiting features.

[0010] In this invention, the anti-spoofing light source is located on the side of the camera facing the acquisition port.

[0011] In this invention, the acquisition terminal further includes a lifting assembly, which is disposed inside the housing, and the camera is fixed on the lifting assembly; the lifting assembly is electrically connected to the controller and is used to drive the camera to move in a direction close to or away from the acquisition port in order to adjust the camera's shooting focal length.

[0012] In this invention, the acquisition terminal further includes a rotating component, which is disposed between the housing and the camera and electrically connected to the controller. The rotating component is used to drive the camera to rotate around a vertical or horizontal axis to change the shooting angle of the camera for the anti-counterfeiting features of the document.

[0013] In this invention, the acquisition terminal further includes a rotating component, which is disposed between the lifting component and the camera and electrically connected to the controller. The rotating component is used to drive the camera to rotate around a vertical or horizontal axis to change the shooting angle of the camera for the anti-counterfeiting features of the document.

[0014] In this utility model, the data acquisition terminal further includes: A light-transmitting plate is fixed inside the housing and blocks the acquisition port. The light-transmitting plate is located between the camera and the acquisition port.

[0015] In this invention, the data acquisition terminal further includes at least two support members, which are fixed to the bottom of the outer casing and evenly distributed around the data acquisition port. The bottom end of the support protrudes from the bottom of the outer shell to reduce the contact area between the data collection terminal and the document, making it easier for the data collection terminal to move on the surface of the document.

[0016] In this utility model, the data acquisition terminal further includes a first pressing block and a second pressing block. The first pressing block and the second pressing block are respectively fixed to the bottom of the outer shell and located on opposite sides of the acquisition port. The bottom end is flush with the bottom end of the support member. They are used to flatten the certificate when collecting anti-counterfeiting information to avoid the certificate wrinkles causing distortion of anti-counterfeiting feature acquisition.

[0017] In this utility model, the data acquisition terminal further includes: The input module, fixed to the outer surface of the housing and electrically connected to the controller, is used to acquire information about the country of issuance of the document. Input methods include key press, voice or image recognition input. The magnification module, located inside the housing and electrically connected to the controller, is used to magnify microtext, laser holographic patterns, or watermark-type anti-counterfeiting information. The extraction module, housed within the casing and electrically connected to the controller, is used to extract multiple independent anti-counterfeiting information from the captured image; and The alarm module, electrically connected to the controller, is used to issue visual or audible alarms when the comparison results are inconsistent.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The cloud-based collaborative document anti-counterfeiting feature recognition device of this utility model adopts a collaborative architecture of acquisition terminal and server. The server undertakes the storage and comparison functions of anti-counterfeiting information, and the acquisition terminal does not need to integrate complex storage and computing modules. It can realize miniaturized and lightweight design, which is convenient for border inspection personnel to operate by hand. The data acquisition terminal uses a camera to accurately capture anti-counterfeiting features of passports, such as microtext, laser holographic patterns, and infrared ink images. Combined with a controller, the information is transmitted in real time. This avoids overlooking or misjudging features due to manual observation or simple tools, significantly reducing the time required to authenticate a single passport. It effectively adapts to high-traffic border inspection scenarios resulting from increased global travel, reducing queues and congestion. Simultaneously, the server pre-stores and updates standard anti-counterfeiting information for passports from different countries in real time. This overcomes the limitations of manual experience-based methods by using standardized data, reducing errors caused by staff unfamiliar with the anti-counterfeiting features of foreign passports and accurately identifying highly counterfeit passports. It also dynamically adapts to the iterative upgrades of passport anti-counterfeiting standards in various countries, avoiding the database lag issues of traditional stand-alone devices. Furthermore, it simplifies the operation process, lowers the business threshold and training costs for border inspection personnel, and ensures the stability and timeliness of authentication results in different scenarios.

[0019] The data acquisition terminal integrates a counterfeit detection light source, a lifting component, and a rotating component. The counterfeit detection light source can excite ultraviolet and infrared latent anti-counterfeiting features and can adapt to different types of anti-counterfeiting features. The lifting component can adjust the focal length to ensure clear imaging, and the rotating component can collect multi-dimensional states of angle-sensitive anti-counterfeiting features, comprehensively covering the types of anti-counterfeiting features on documents and improving the accuracy of authenticity judgment.

[0020] The light-transmitting plate extends the equipment's lifespan, the support components reduce operating resistance, and the first and second pressure blocks prevent image distortion caused by document wrinkles, further enhancing the device's practicality and reliability.

[0021] The inclusion of input, magnification, extraction, and alarm modules gives the device additional functions such as "country-specific adaptation," "fine magnification," "efficient extraction," and "anomaly alerts." These features not only assist border inspection personnel in quickly and comprehensively collecting anti-counterfeiting information but also provide timely warnings of counterfeit documents, further enhancing the efficiency and accuracy of border inspection work.

[0033] The following is a preferred embodiment of a cloud-based collaborative document anti-counterfeiting feature recognition device that can solve the above technical problems.

[0034] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the overall structure of a preferred embodiment of the cloud-based collaborative document anti-counterfeiting feature recognition device of this utility model. Figure 2 This is a three-dimensional view of the overall structure of the data acquisition terminal of a preferred embodiment of the cloud-based collaborative document anti-counterfeiting feature recognition device of this utility model.

[0035] In the diagram, units with similar structures are represented by the same labels.

[0036] This utility model provides a device for cloud-based collaborative identification of document anti-counterfeiting features, including a data acquisition terminal 1 and a server 2, which are communicatively connected; the data acquisition terminal 1 includes a housing 11, a camera 12, and a controller 21 (see...). Figure 3 The outer shell 11 is a hollow box structure with a collection port 111. The camera 12 is installed inside the outer shell 11 and is aligned with the collection port 111. The controller 21 is installed inside the outer shell 11 and is connected to the camera 12.

[0037] Server 2 stores standard anti-counterfeiting information for documents from different countries. Controller 21 is used to send the document anti-counterfeiting information collected by camera 12 to server 2. Server 2 is used to compare the collected anti-counterfeiting information with the standard anti-counterfeiting information and feed the comparison result back to collection terminal 1.

[0038] The following is a detailed description of the cloud-based collaborative document anti-counterfeiting feature recognition device in this embodiment: Combination Figure 3 The acquisition port 111 is located at the bottom of the housing 11, and the top of the housing 11 is equipped with a display screen 13. The display screen 13 is electrically connected to the controller 21 and is used to display the comparison results. The comparison results may simply be consistent or inconsistent, or they may be further specified, such as including the number of identified features, the comparison status of individual features, and whether the overall results are consistent.

[0039] The acquisition terminal 1 also includes a lifting component 15, which is fixed inside the housing 11. The camera 12 is fixed to the moving end of the lifting component 15. The lifting component 15 is electrically connected to the controller 21 and can drive the camera 12 to move in the direction of approaching or moving away from the acquisition port 111 under the control of the controller 21, thereby adjusting the shooting focal length of the camera 12 to ensure that anti-counterfeiting features of different sizes and distances can be clearly imaged.

[0040] A fixing plate 113 is provided inside the outer casing 11. The controller 21 is located between the top surface of the fixing plate 113 and the inner top surface of the outer casing 11. The outer contour of the controller 21 together forms a closed receiving slot. The internal size of the receiving slot is adapted to the controller 21. The controller 21 is embedded in the receiving slot, which effectively avoids collision damage caused by shaking of the outer casing 11. At the same time, the bottom surface of the fixing plate 113 is provided with a mounting interface (such as an internal threaded hole or a snap-fit ​​structure) adapted to the top of the lifting assembly 15. The top of the lifting assembly 15 is detachably connected to the interface by bolts or snaps. The central axis of the lifting assembly 15 is vertically aligned with the center of the bottom acquisition port of the outer casing 11, ensuring that it always faces the acquisition area when driving the camera 12 to move. In addition, the fixing plate 113 divides the interior of the outer casing 11 into an "upper control area" (the receiving slot is used to install the controller) and a "lower execution area" (the lifting assembly, camera, etc. are installed), realizing the partitioned layout of components and avoiding the tangling of component wires.

[0041] In this embodiment, the outer surface of the outer shell 11 is provided with a handhold with anti-slip texture 112, which makes it convenient for the user to hold and use.

[0042] Combination Figure 4Furthermore, the acquisition terminal 1 also includes a counterfeit detection light source 14, which is disposed inside the housing 11. The counterfeit detection light source 14 includes at least two of the following: infrared light source, ultraviolet light source, and visible light source. By switching between different types of counterfeit detection light sources 14, different types of anti-counterfeiting features (such as colorless fluorescent graphics and infrared graphics) on the document can be displayed, facilitating the camera 12 to fully acquire anti-counterfeiting information. In this embodiment, the counterfeit detection light source 14 is located on the side of the camera 12 facing the acquisition port 111. In other embodiments, the counterfeit detection light source 14 can be flexibly arranged inside the housing 11, such as on the inner wall of the housing 11.

[0043] Furthermore, the acquisition terminal 1 also includes a rotating component 16, which is disposed between the housing 11 and the camera 12, and is electrically connected to the controller 21. The rotating component 16 can drive the camera 12 to rotate around a vertical or horizontal axis, changing the shooting angle of the camera 12 for the anti-counterfeiting features of the document. Specifically, for "angle-sensitive" anti-counterfeiting features such as optically variable ink patterns, the feature state at different angles can be collected by rotating the camera 12, improving the accuracy of authenticity judgment. In this embodiment, the rotating component 16 is disposed between the moving end of the lifting component 15 and the camera 12. In other embodiments, the lifting component 15 can also be disposed between the rotating component 16 and the camera 12.

[0044] Combination Figure 2 and Figure 3 The data acquisition terminal 1 also includes a light-transmitting plate 17, which is fixed inside the housing 11. The light-transmitting plate 17 blocks the acquisition port 111 and is located between the camera 12 and the acquisition port 111. In this embodiment, the light-transmitting plate 17 is made of high light transmittance wear-resistant glass, which can ensure that the camera 12 can clearly collect anti-counterfeiting information, and can also prevent dust and impurities from entering the housing 11. At the same time, it can prevent the certificate from directly contacting the camera 12 and causing wear, thus extending the service life of the data acquisition terminal 1.

[0045] Combination Figure 3 The data collection terminal 1 also includes at least two support members 18. The support members 18 are fixed to the bottom of the outer shell 11 and are evenly distributed around the data collection port 111. Their bottom ends protrude from the bottom of the outer shell 11. The support members 18 can reduce the contact area between the data collection terminal 1 and the surface of the document, reduce the resistance to movement, and make it convenient for border inspection personnel to hold the data collection terminal 1 and slide it on the surface of the document to quickly collect anti-counterfeiting features at different locations.

[0046] Furthermore, the data acquisition terminal 1 also includes a first pressing block 19 and a second pressing block 20. The first pressing block 19 and the second pressing block 20 are respectively fixed to the bottom of the outer shell 11 and located on opposite sides of the acquisition port 111. The bottom ends of the first pressing block 19 and the second pressing block 20 are flush with the bottom end of the support member 18. When collecting anti-counterfeiting information, the first pressing block 19 and the second pressing block 20 can flatten the surface of the document, avoiding unclear imaging or distortion of anti-counterfeiting features due to document wrinkles or curling, and preventing document wrinkles from causing distortion in the acquisition of anti-counterfeiting features, thus ensuring the accuracy of the collected information.

[0047] Furthermore, the data acquisition terminal 1 in this embodiment also includes an input module, which is fixed to the outer shell 11 and electrically connected to the controller 21. The input methods include key input, voice input, or image recognition input. This module is used by border inspection personnel to input the country of issue for their documents. The controller 21 can send this country information to the server 2. The server 2 retrieves the corresponding country's document anti-counterfeiting feature database (including the quantity, location, and shape information of anti-counterfeiting features) and feeds it back to the data acquisition terminal 1, assisting border inspection personnel in comprehensively collecting anti-counterfeiting information. Specifically, the input module can be fixed to the outer surface of the outer shell 11.

[0048] Furthermore, the acquisition terminal 1 in this embodiment also includes an amplification module, which is located inside the outer shell 11 and is electrically connected to the controller 21. The amplification module can amplify the "small and precise" anti-counterfeiting features such as microtext, laser holographic patterns, and watermarks collected by the camera 12, so as to facilitate accurate comparison by the server 2 and manual verification by border inspection personnel.

[0049] Furthermore, the acquisition terminal 1 in this embodiment also includes an extraction module, which is located inside the housing 11 and electrically connected to the controller 21. The extraction module can extract multiple independent anti-counterfeiting information from a single image captured by the camera 12, avoiding repeated shooting and improving acquisition efficiency. Optionally, the anti-counterfeiting features magnified by the magnification module can be displayed on the display screen 13.

[0050] Furthermore, the data acquisition terminal 1 in this embodiment also includes an alarm module. The alarm module is electrically connected to the controller 21. When there is an inconsistency in the comparison results fed back by the server 2 (i.e. the document may be forged), the alarm module can issue a visual alarm (such as the display screen 13 flashing) or an auditory alarm (such as a buzzer) to promptly remind border inspection personnel to conduct key checks.

[0051] In this embodiment, the acquisition terminal 1 includes an input module, a magnification module, an extraction module, and an alarm module. In other embodiments, some modules may be omitted.

[0052] Combination Figure 5 The working principle of this utility model is as follows: 1. Preliminary Preparation and Country-Specific Adaptation: Border inspection personnel use handheld data collection terminal 1 to input document issuance country information via the input module (button, voice, or image recognition input) on the outer surface of the casing 11. After receiving the country information, controller 21 sends it to server 2. Server 2 retrieves the document anti-counterfeiting feature database (including the quantity, location, and shape of anti-counterfeiting features) for the corresponding country and feeds the database information back to data collection terminal 1 to provide guidance for subsequent accurate data collection.

[0053] 2. Anti-counterfeiting feature acquisition and adjustment: Border inspection personnel align the acquisition port 111 at the bottom of the acquisition terminal 1 with the area to be inspected on the document. The support 18 at the bottom of the outer shell 11 reduces the contact area between the terminal and the document, facilitating sliding along the surface of the document. At the same time, the first pressing block 19 and the second pressing block 20 flatten the document, avoiding wrinkles that could cause image distortion. Depending on the type of anti-counterfeiting feature to be acquired, the controller 21 switches the anti-counterfeiting light source 14 (e.g., ultraviolet light source to excite colorless fluorescent images, infrared light source to excite infrared images).

[0054] If it is necessary to capture small features such as microtext, the controller 21 activates the magnification module to magnify the image; for angle-sensitive features such as optically variable ink patterns, the rotating component 16 drives the camera 12 to rotate around the vertical or horizontal axis to adjust the shooting angle; if the image is blurry, the lifting component 15 drives the camera 12 to move closer to or further away from the acquisition port 111 to adjust the focus until the image is clear. During this process, the light-transmitting plate 17 blocks dust and impurities, protecting the camera 12 without affecting the image quality.

[0055] 3. Information Transmission and Cloud Comparison: After camera 12 captures a clear image of the anti-counterfeiting features, the extraction module extracts multiple independent anti-counterfeiting information from a single image. Controller 21 sends the extracted anti-counterfeiting information to server 2. Server 2 calls the pre-stored corresponding national standard anti-counterfeiting information and compares the captured information with the standard information one by one, generating a comparison result. The comparison result can simply be consistent or inconsistent, or it can be further specified, such as including the number of identified features, the comparison status of individual features, and whether the overall results are consistent.

[0056] 4. Result Feedback and Anomaly Alerts: Server 2 feeds back the comparison results to acquisition terminal 1. Controller 21 controls the top display screen 13 to display the results for border inspection personnel to view intuitively. If the comparison results are inconsistent (the document may be forged), the alarm module immediately triggers a visual alarm (such as flashing display screen 13) or an audible alarm (such as a buzzer) to remind border inspection personnel to conduct a thorough check. If the comparison is consistent, border inspection personnel can continue to collect features from other areas using the mobile terminal, or end the document verification process and enter the next document detection cycle.

[0057] This completes the working process of the device based on cloud-based collaborative document anti-counterfeiting feature recognition in this preferred embodiment.

[0058] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
