Description

Technical Field

[0001] The present invention relates to the technical field of document destruction, and in particular to a document destruction method, system, device and storage medium. Background Art

[0002] ID cards, as a symbol of identity, are widely used in everyday life. In some scenarios, to ensure the validity and uniqueness of ID cards, when the ID card expires or when multiple copies of the same ID card exist, the expired or redundant ID card needs to be destroyed to ensure normal use in the scenario.

[0003] The current document destruction method involves placing documents into a destruction machine and then operating it to destroy them. Factors such as document material, feed direction, and document size can lead to incomplete destruction of documents during destruction. This can result in the destruction of documents being recyclable and reusable, reducing the quality of document destruction. Summary of the Invention

[0097] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0098] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0099] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used herein are for the purpose of describing embodiments of the present invention only and are not intended to limit the present invention.

[0100] The existing document destruction method usually requires the user to place the document into the destruction machine, and then operate the machine to destroy the document. However, due to factors such as the document material and the feeding direction, the document destruction is prone to incomplete, so that important document information is still carried on the destroyed document, resulting in the destroyed document still being able to be used on the market, and the quality of document destruction is low.

[0101] In order to overcome the defects in the prior art, the present application discloses a method for destroying a certificate. For ease of understanding, in one embodiment, as shown in FIG. Figure 1As shown, the document destruction method disclosed in this embodiment is applied to the document destruction device. The document destruction device includes a mounting frame 100, a feed assembly 200, a destruction assembly 300, a reader assembly 400, and a controller. The mounting frame 100 includes a loading area 101 and a destruction area 102. The feed assembly 200 is located within the loading area 101, and the destruction assembly 300 is located within the destruction area 102. The feed assembly 200 moves documents in the loading area 101 to the destruction assembly 300 in the destruction area 102, where the destruction assembly 300 can destroy the documents transferred to the destruction area 102. The reader assembly 400 is connected to the mounting frame and located on one side of the feed assembly 200. In one application scenario, the reader assembly 400 is located below the feed assembly 200 and is used to read readable information on the document. This readable information includes QR codes, document thickness, total weight, and document outline. The reading component may adopt OCR recognition or a scanning module with a scanning function, which is not specifically limited in this embodiment.

[0102] like Figure 1 and Figure 2 As shown, the document destruction device also includes a feed module 29 located in the loading area 101. Feed module 29 is located at the end of the feed assembly 200 away from the destruction assembly 300. After a user feeds a document into feed module 29, it is transported along feed module 29 to feed assembly 200. From there, it is transferred by feed module 200 to destruction assembly 300 located in the destruction area 102, where it is destroyed by destruction assembly 300. Exemplarily, feed module 29 includes a feed drive 291, a feed rack 292 driven by feed drive 291, at least one feed channel 293 disposed below feed rack 292, and a plurality of feed ports 294 disposed in each feed channel 293.

[0103] In this embodiment, each feed channel 293 has a feed level difference, and the feed drive 291 can drive the feed rack 292 to move up and down to switch the feed channels 293. Optionally, each feed channel 293 includes a first feed channel 2931 for moving in a personal ID card and a second feed channel 2932 for moving in a card ID card. Generally, the size of a personal ID card is larger than that of a card ID card. Therefore, in this embodiment, the two ends of the first feed channel 2931 are respectively abutted against the two ends of the bottom plate of the feed rack 292, and the second feed channel 2932 can be embedded in the middle of the first feed channel 2931. In addition, the distance between the first feed channel 2931 and the plane where the ID card is inserted is smaller than the distance between the second feed channel 2932 and the plane where the ID card is inserted, thereby ensuring a height difference in feeding between the first feed channel 2931 and the second feed channel 2932. At the same time, the feed port 294 includes a first feed port 2941 set in the first feed channel 2931, and the card-type certificate can enter along the first feed port 2941; the feed port 294 also includes a second feed port 2942 set in the second feed channel 2932, and the card-type certificate can enter along the second feed port 2942.

[0104] In this embodiment, in the initial state, the first feed channel 2931 is arranged to abut against the document insertion plane. At this time, the distance between the second feed channel 2932 and the document insertion plane is just adapted to the thickness of the card-type document, that is, the card-type document can be inserted along the second feed opening 2942 and reach the moving range of the feeding assembly 200. In addition, when the feed drive 291 drives the feed rack 292 to move upward away from the document insertion plane until the distance between the second feed channel 2932 and the document insertion plane is just adapted to the thickness of the card-type document, that is, the card-type document can be inserted along the first feed opening 2941 and reach the moving range of the feeding assembly 200. After the card-type document is inserted, the feed drive 291 drives the feed rack 292 to move downward toward the document insertion plane until it abuts against the document insertion plane, reaching the initial state. By setting up two feeding channels 293 with a feeding height difference and a feeding height difference between the two feeding channels 293, the feeding channels can be quickly switched when feeding different types of documents, thereby improving the feeding efficiency, simplifying the structure and saving production costs.

[0105] Based on the above-mentioned document destruction device, a document destruction method of this application is described in detail. Figure 3 As shown, a document destruction method disclosed in an embodiment of the present application includes:

[0106] 101. After obtaining the authorization instruction for the certificate to be destroyed, obtain the preset certificate feature information corresponding to the authorization instruction and the certificate target information obtained in real time.

[0107] In one embodiment, before destroying a document to be destroyed, it is necessary to first use an identification component to identify basic information of the document to be destroyed, such as the document number, anti-counterfeiting code, etc. After obtaining the basic information of the document to be destroyed, the basic information of the document to be destroyed is stored as document feature information in a storage space.

[0108] The user then authorizes the destruction of the document by operating a human-computer interaction terminal, such as a keyboard, mouse, or touchscreen. During authorization, the user selects and / or enters information such as the document number and the name of the holder of the document. After completing this selection and / or entry, the user signs to complete the authorization. The controller then generates an authorization instruction based on the user's selection and / or entry. Specifically, the authorization instruction includes at least one of the document number, the associated user name, and the associated user phone number of the document to be destroyed. The information contained in the authorization instruction can be used to retrieve the corresponding document feature information from the storage space.

[0109] In another embodiment, when a user applies for a certificate, i.e., when the certificate is associated with the user, the basic certificate information and the associated user information are stored in the storage space as certificate feature information. When the user wishes to destroy the certificate, the controller generates an authorization instruction based on the certificate information and / or user information entered by the user through the human-computer interaction terminal, and then retrieves the corresponding certificate feature information from the storage space based on the certificate information and / or user information contained in the authorization instruction.

[0110] It should be noted that the authorization instruction contains at least one unique identifier of the document to be destroyed. The unique identifier can be the document number or the user ID number associated with the document to be destroyed. This is not specifically limited in this embodiment. The document feature information is associated with, or contains, a unique identifier, and the purpose is to be able to find the document feature information corresponding to the document to be destroyed in the storage space based on the unique identifier. It is not difficult to see that the authorization instruction is generated at the time of authorization; the document feature information is stored in the storage space before authorization. In order to improve the accuracy of document destruction, the document target information of the document to be destroyed after authorization is obtained. In one embodiment, the document target information is obtained by reading the reading component and then transmitted to the controller.

[0111] In one embodiment of the present invention, the document destruction method, after obtaining the authorization instruction of the document to be destroyed and before obtaining the preset document feature information corresponding to the authorization instruction and the document target information obtained in real time, further includes: generating a driving instruction based on the authorization instruction, and the driving instruction is used to control the movement of the feed module 29 of the document destruction device so that the document destruction device reveals the first feed port 2941 or the second feed port 2942.

[0112] 102. When the certificate feature information matches the certificate target information, generate a destruction instruction.

[0113] If the document feature information matches the document target information, it means that the document to be destroyed authorized by the user and the document to be destroyed in the current document destruction device are the same document, which helps to ensure the accuracy of document destruction and avoid the situation where the document actually destroyed is inconsistent with the document the user wants to destroy.

[0114] The destruction instruction is used to control a destruction mechanism to destroy a document to be destroyed. A destruction mechanism refers to an institution with document destruction capabilities. It should be noted that, in one embodiment, when destroying a document to be destroyed, holes are punched into the document based on the document type and / or the target location on the document. Destruction is considered complete when specific information or a specific area on the document is removed through punching.

[0115] 103. Obtain document verification information of the document to be destroyed after destruction.

[0116] The document verification information refers to the information obtained based on the document to be destroyed after it is destroyed. In one embodiment, after the document to be destroyed is destroyed by the destruction component, the feeding component transmits the destroyed document to be destroyed to the reading component, and the reading component reads the destroyed document to be destroyed to obtain the document verification information.

[0117] 104. Generate an instruction when the difference between the verification image information in the certificate verification information and the target image information in the certificate target information is less than a preset difference threshold.

[0118] In one embodiment, in contrast, when the difference value is greater than or equal to the difference threshold, no instruction is generated, and the controller can control the feeding component to return the card, or allow the destroyed document to fall into a recycling box.

[0119] The instruction is intended to initiate subsequent processing of the destroyed document when the difference value is less than a difference threshold. For example, in one embodiment, the instruction is used to control the destruction component to perform a secondary destruction of the document; in another example, the instruction is used to generate and output a warning message indicating a destruction failure. It should be noted that if the difference value between the verification image information and the target image information is less than the difference threshold, it indicates that the difference between the destroyed document and the original document is small. In this case, the instruction is generated to facilitate the secondary destruction of the destroyed document, thereby ensuring the quality of destruction.

[0120] On the one hand, before destroying the document, the document target information of the document to be destroyed is compared with the document feature information. If the two match, it proves that the document to be destroyed is the same document as the document authorized for destruction by the user. It is less likely that the document authorized for destruction is different from the document actually destroyed, thereby ensuring the quality of destruction. On the other hand, after destruction, by comparing the document verification information and the document target information, it is determined whether the destruction is sufficient. If not, an instruction is generated to facilitate subsequent processing of the documents that were not sufficiently destroyed, thereby improving the quality of destruction.

[0121] In one embodiment, the number of times the instruction is generated is accumulated. When the number of times the instruction is generated is greater than a preset threshold, the operation of destroying the certificate is suspended and a warning message is generated.

[0122] In another embodiment of the present invention, in order to further define and illustrate, Figure 4 As shown, the steps of generating the instruction include:

[0123] 201. Obtain first object information of a preset target damage position in the target image information.

[0124] In one embodiment, the target destruction location is preset, with different target destruction locations being preset for different types of documents to be destroyed. The types of documents to be destroyed include, but are not limited to, document types and card types. In another embodiment, the target destruction location includes both preset target destruction locations and user-selected target destruction locations. Specifically, when authorizing document destruction, the user selects the target destruction location they desire.

[0125] In one embodiment, the target damage location is set based on the pixel coordinates of the target image information. For example, if the target image information corresponds to a pixel size of 368*368, i.e., 368 rows and 368 columns of pixels, the target damage location can be one of the pixels, such as (55.55), or a region consisting of four pixels.

[0126] The first object information may be image information corresponding to the target damage location in the target image information, or may be graphic information corresponding to the target damage location, wherein the graphic information is information of text graphics, symbol graphics, and / or digital graphics extracted from the target image information corresponding to the target damage location.

[0127] 202. Obtain second object information corresponding to the target damage position in the verification image information.

[0128] The acquisition method and specific content of the second object information are similar to those of the first object information and will not be repeated here. The difference is that the second object information is obtained from the verification image information, and the target damage position continues to use the target damage position of the first object information.

[0129] 203. Compare the first object information and the second object information, and calculate the overlapping area.

[0130] In one embodiment, image recognition technology is used to identify the same image area in the first object information and the second object information to obtain the repeated area.

[0131] 204. When the repeated area is larger than a preset area threshold, generate the instruction to destroy the document to be destroyed again.

[0132] That is, in this embodiment, the repeated area is greater than the area threshold, which proves that the difference between the verification image information and the target image information is less than the difference threshold. At this time, the document to be destroyed is destroyed again, which helps to improve the quality of document destruction.

[0133] By extracting the target image information and verifying the object information in the image information, calculating the repeated area, and then judging the size of the difference value, the method has high accuracy and small calculation amount, which helps to save resources, improve efficiency, and reduce the time users wait for document destruction, thereby improving the user's document destruction experience.

[0134] In another embodiment, when the repeated area is less than or equal to a preset area threshold, a card return instruction is generated to output the destroyed certificate.

[0135] Returning successfully destroyed certificates to users helps ensure that the destroyed certificates are not easily lost to other people, thereby protecting the user's personal information on the certificate and improving the user's information security.

[0136] In another embodiment of the present invention, for further definition and explanation, before the step of generating the destruction instruction, the method further includes:

[0137] 301. Extract feature identification information from feature image information of the document feature information.

[0138] Document characteristic information includes characteristic image information, which can be image information of a single side of the document to be destroyed, image information of a portion of a single side of the document to be destroyed, or image information of both the front and back of the document to be destroyed. Characteristic identification information is intended to uniquely identify the corresponding document. Therefore, in one embodiment, the characteristic identification information can be the document number extracted from the characteristic image information. In another embodiment, the characteristic identification information can be a user number extracted from the characteristic image information.

[0139] 302. Extract target identification information from the target image information.

[0140] It should be noted that target identification information corresponds to feature identification information, differing only in that feature identification information is extracted from feature image information, while target identification information is extracted from target image information. The correspondence between target identification information and feature identification information means that if the feature identification information is a document number, the target identification information is also the document number; if the feature identification information is a user number, the target identification information is also the user number.

[0141] In addition, there is no order restriction for acquiring the feature identification information and the target identification information. They can be acquired simultaneously or sequentially. When acquiring simultaneously, it is sufficient to set the content attributes corresponding to the feature identification information and the target identification information to be the same in advance.

[0142] 303. Compare the feature identification information and the target identification information to see if they are the same.

[0143] In one embodiment, after extracting the feature identification information and the target identification information, the controller converts both the feature identification information and the target identification information into character form and then compares them. In another embodiment, the controller uses an image recognition program or software to compare the feature identification information and the target identification information to determine whether they are identical.

[0144] If they are the same, it is determined that the document feature information matches the document target information.

[0145] Correspondingly, if they are not the same, it is determined that the document feature information does not match the document target information.

[0146] By extracting corresponding identification information from the image information corresponding to the document feature information and the document target information, and then comparing them, it is determined whether the document feature information and the document target information match. The image information can more fully reflect the characteristics of the document feature information and the document target information, which is conducive to determining whether the corresponding documents are the same document, thereby improving the accuracy of the judgment.

[0147] In another embodiment of the present invention, for further definition and explanation, the document target information also includes target basic information.

[0148] The target basic information may include other document information in addition to the target image information, such as the weight and thickness of the document to be destroyed.

[0149] After determining that the document feature information matches the document target information in step, the method further includes:

[0150] 401. Identify whether the document to be destroyed is a counterfeit document based on the target image information and the target basic information.

[0151] The target image information and target basic information can more comprehensively describe the information of the document to be destroyed, thereby facilitating the determination of whether the document to be destroyed is a counterfeit document.

[0152] If so, execute step 402 to generate an execution instruction corresponding to the counterfeit certificate; the execution instruction corresponding to the counterfeit certificate is used to mark the certificate feature information, destroy the certificate to be destroyed, and output counterfeit warning information.

[0153] If not, execute step 403 to generate the destruction instruction.

[0154] Before generating a destruction instruction, the system determines whether the document to be destroyed is a counterfeit. If so, it is destroyed and marked with the corresponding document characteristics to alert the user to the existence of a counterfeit document. The output of the counterfeit warning information also serves to remind the relevant document management personnel to deal with the counterfeit document.

[0155] By determining whether the document to be destroyed is a counterfeit, the accuracy of the information updated in the document system during destruction is ensured. This prevents counterfeit documents from defrauding the system while retaining genuine documents for continued use. This improves the accuracy of document destruction and further enhances its quality.

[0156] In another embodiment of the present invention, in order to further define and illustrate, Figure 5 As shown, the step of identifying whether the document to be destroyed is a counterfeit document based on the target image information and the target basic information includes:

[0157] 501. Extract target type identification information from the target image information.

[0158] The target type identification information is intended to indicate the document type. For example, in one embodiment, the target type identification information is the outline information of the document to be destroyed; that is, the type of the document to be destroyed can be determined based on the size of the outline. In another embodiment, the target type identification information is the text information of the document type to be destroyed; that is, information containing the type text is extracted from the target image information. If the type text is "Card", it indicates that the document to be destroyed is of the card type; if the type text is "This Class", it indicates that the document to be destroyed is of this class.

[0159] 502. Compare the target type identification information with a preset certificate type model to obtain certificate type information.

[0160] There can be multiple certificate type models of the same type. During comparison, the target type identification information is compared with each certificate type model. When the target type identification information matches one of the certificate type models, the type information corresponding to the certificate type model is retrieved as the certificate type information.

[0161] 503. Extract target anti-counterfeiting identification information from the target image information according to the certificate type information.

[0162] Different types of documents have different anti-counterfeiting information. For example, in one embodiment, the target anti-counterfeiting information for cards is an anti-counterfeiting symbol, while the target anti-counterfeiting information for this category is a QR code. After determining the type of document to be destroyed, the target anti-counterfeiting information can be extracted from the target image information based on the location information of the corresponding anti-counterfeiting identifier.

[0163] 504. When the target anti-counterfeiting identification information is image-type identification information, the target anti-counterfeiting identification information is compared with the corresponding image-type identification model, the similarity is calculated, and it is determined whether the similarity matches a preset similarity threshold to identify whether the document to be destroyed is a counterfeit document.

[0164] The similarity can be calculated as the ratio of the overlapping area to the total area. The similarity threshold can be a single value or a range of values. When the similarity threshold is a single value, the similarity is considered a match when the similarity is greater than or less than the threshold. When the similarity threshold is a range of values, the similarity is considered a match when the similarity is within the range of values ​​corresponding to the similarity threshold.

[0165] And / or, 505 , when the target anti-counterfeiting identification information is scan code identification information, scan the target anti-counterfeiting identification information to obtain authenticity result information, and determine whether the document to be destroyed is a counterfeit document based on the authenticity result information.

[0166] It should be noted that after scanning the target anti-counterfeiting mark information, you will enter the web page or mini program, and you can get the authenticity result information from the web page or mini program.

[0167] By obtaining the target anti-counterfeiting identification information and adopting different acquisition methods for different types of certificates, it is possible to determine whether the certificate to be destroyed is a counterfeit certificate. This helps to improve the authenticity and accuracy of the judgment results. The method is simple and helps to save resources.

[0168] In another embodiment of the present invention, in order to further define and illustrate, Figure 6 As shown, the step of identifying whether the document to be destroyed is a counterfeit document based on the target image information and the target basic information includes:

[0169] 601. Extract target type identification information from the target image information.

[0170] 602. Compare the target type identification information with a preset certificate type model to obtain certificate type information.

[0171] 603. Retrieve corresponding weight threshold and thickness threshold according to the document type information.

[0172] Different types of documents have different weights and thicknesses. Before destroying documents, they can be sorted manually or mechanically to remove foreign objects attached to or contained in the documents to be destroyed, so as to ensure the accuracy of determining the authenticity of the documents to be destroyed.

[0173] 604. Determine whether the target weight information in the target basic information matches the weight threshold, and determine whether the target thickness information in the target basic information matches the thickness threshold, so as to identify whether the document to be destroyed is a counterfeit document.

[0174] For ease of understanding, for example, in one application scenario, image recognition software or a program is used to scan the target image information to obtain information about each region within the target image information. Information within a pre-defined identification region is then obtained and determined as target type identification information. When comparing the target type identification information with a document type model, the outline of the target type identification information is scanned and compared with the document type model. If the outlines are identical, the target type identification information is confirmed to match the document type model, thereby obtaining the document type information associated with the document type model.

[0175] By using the target weight information and target thickness information to judge the authenticity of the document to be destroyed, the logic is simple and the process is fast, which helps to improve the efficiency of document destruction.

[0176] In another embodiment of the present invention, for further definition and explanation, before the step of generating the instruction, the method further includes:

[0177] 701. Acquire text information in the target image information.

[0178] Image recognition technology can be used to extract text from target image information. For example, after scanning the target image, several structural shapes are obtained. These structural shapes are then compared with pre-set text models. If they match, the corresponding structural shapes are determined to be the text corresponding to the text model, thereby obtaining the text information.

[0179] 702. Compare the text information with preset key information.

[0180] Key information refers to information that needs to be destroyed when a certificate is destroyed. Because certificates of the same type are uniform, key information can be preset in advance. In one embodiment, key information includes at least one of the certificate number, user name, user ID number, and user contact information.

[0181] In another embodiment, the key information can be set to the information of the certificate corresponding to the authorization instruction of the current certificate to be destroyed, for example: the certificate information includes at least one of the certificate number, user name, user ID number, and user contact information.

[0182] 703. If there is duplicate information in the text information that is duplicate of the key information, generate first repair and destruction position information according to the position of the duplicate information in the target image information, and execute the generating instruction.

[0183] The instruction is generated according to the first repair and destruction position information, so that the instruction carries the first repair and destruction position information.

[0184] 704. If there is no duplicate information of the key information in the text information, generate second repair and destruction position information according to the position where the first object information and the second object information are repeated, and execute the generating instruction.

[0185] If all key information has been removed, but the repeated area is larger than the area threshold, the repeated part will be removed to ensure the quality and accuracy of document destruction.

[0186] In another embodiment of the present invention, for further definition and explanation, after the step of obtaining the authorization instruction for the document to be destroyed, the method further includes:

[0187] 801. Obtain the document type of the document to be destroyed according to the authorization instruction.

[0188] In one embodiment, the authorization instruction carries the certificate type of the certificate to be destroyed. In another embodiment, the certificate feature information stored in the storage space includes the certificate type, and the certificate type can be obtained by searching the certificate feature information according to the authorization instruction.

[0189] 802. Call a corresponding destruction program according to the certificate type.

[0190] It should be noted that, in combination with the document destruction device mentioned above, since the feeding module has different action modes for different types of documents, after determining the document type, the corresponding destruction program is called to control the feeding module to act in a manner corresponding to the document type.

[0191] By setting different destruction procedures, it is convenient to adopt different insertion mechanisms and destruction mechanisms for different types of documents to be destroyed, so as to improve the quality of document destruction.

[0192] After receiving the authorization instruction, real-time document target information is obtained and compared with the document's characteristic information to ensure that the authorized document and the actual document to be destroyed are the same, thus preventing incorrect destruction. The document to be destroyed is then identified as a counterfeit, thereby improving the accuracy of document destruction. Finally, the document to be destroyed is inspected to determine the difference between the document verification information and the document target information. If the difference is significant, an instruction is generated to re-destroy the document to be destroyed, helping to ensure that the document to be destroyed is authentically and fully destroyed, thereby improving the quality of document destruction.

[0193] The present application also discloses a document destruction system.

[0213] And / or, when the target anti-counterfeiting identification information is scan code identification information, the target anti-counterfeiting identification information is scanned to obtain authenticity result information, and whether the document to be destroyed is a counterfeit document is determined according to the authenticity result information.

[0229] A controller, which is provided on the frame and is used to obtain, after receiving an authorization instruction for the document to be destroyed, document feature information preset corresponding to the authorization instruction and document target information obtained in real time by the reading component;
