[0002] In the process of building and operating the knowledge management platform, how to balance the strength of intellectual property protection and the convenience of knowledge acquisition has become a difficult problem that is difficult to solve perfectly. If the method of grouping users and setting corresponding permissions is adopted, this method is more suitable for small enterprises, but for large enterprises it will generate a lot of workload and will seriously affect the convenience of knowledge acquisition; if users are not grouped and the corresponding permissions are not set, it may lead to corporate knowledge leakage.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] In order to better understand the embodiments of the present application, some nouns or terms that appear in the description of the embodiments of the present application are first translated and explained as follows:

[0024] RGB value: RGB refers to the three primary optical colors, namely red, green and blue, and the RGB value specifically reflects the brightness (i.e., intensity value), which is usually represented by integers from 0 to 255, where 255 corresponds to the maximum brightness and 0 corresponds to the minimum brightness. Therefore, R, G, and B each have 256 levels of brightness.

[0025] Example 1

[0026] Enterprises or organizations need to protect confidential documents with high commercial value, such as business contracts, agreement documents, and internal personnel qualification documents, to avoid malicious leakage of the enterprise or organization's knowledge management platform.

[0027] Currently, the commonly used method is to mark documents with data watermark technology to distinguish between document users and those responsible for illegal distribution, so as to hold those responsible for illegal distribution accountable afterwards. However, since such watermarked documents are usually saved in the form of scanned copies, their file types are usually divided into two categories, PDF format and image format.

[0028] For documents in PDF format, you can use PDF readers, such as Acrobat Reader and Foxit Reader, to add watermarks to PDF documents, but users can also use the same software, or advanced versions of the same brand, to remove document watermarks from PDF documents. Alternatively, insert a large number of text boxes into the PDF document, enter the watermark text information in the text boxes, and save it, but this method only works for Acrobat Reader and Foxit Reader without editing permissions. Otherwise, relevant personnel with editing permissions can still easily remove watermarks through these PDF reader software. For documents in image format, you can use image editing software to create a watermark. Figure 1 The watermark image shown. However, since the watermark color and the document background color are clearly distinguished, the user can obtain the RGB value of the watermark image through the image file and modify it to the document background color, thereby easily removing the watermark information.

[0029] Therefore, the document watermark generated by the related technology is easy to remove, resulting in low document security.

[0030] In order to solve the above problems, an embodiment of the present application provides a text document processing method, which makes it difficult to remove the document watermark by setting the document watermark to a gradient color or an irregular color.

[0031] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 2 is a flowchart of an optional text document processing method according to an embodiment of the present application, such as Figure 2 As shown, the method at least includes steps S202-S206, wherein:

[0033] Step S202: Acquire a first text document in image format.

[0034] In the technical solution provided in the above step S202 of the present invention, the first text document in image format can be a scanned copy of a text document such as a commercial contract, company qualifications, agreement contract, etc., wherein the image format can be but is not limited to JPG image or PNG image, etc., and no specific limitation is made here.

[0035] Step S204: determine the document watermark to be added, wherein the document watermark information includes: watermark content and watermark position.

[0036] In the technical solution provided in the above step S204 of the present invention, the document watermark to be added is used to write the ownership information or the downloader's information into the document without affecting the reading of the document, so as to protect the copyright of the document and avoid the leakage of the document due to secondary forwarding. In addition, the watermark position is preferably set at a key position in the document content information, such as signature, amount, time, etc., so as to ensure the protection of key information.

[0037] Step S206, adding a document watermark at a target position of each page of the image file in the first text document to obtain a target text document, wherein the color of each pixel corresponding to the document watermark is any color within the first target color range.

[0038] In the technical solution provided in the above step S206 of the present invention, the color of each pixel corresponding to the document watermark can be set to any color within the first target color range, wherein the first target color needs to be distinguished from the document background (i.e., white), thereby preventing the user from obtaining the RGB value of the watermark image from the image file and modifying the RGB value to the document background color, which causes the user to easily remove the document watermark.

[0039] In the embodiment of the present application, a first text document in image format is obtained; a document watermark to be added is determined, wherein the document watermark information includes: watermark content and watermark direction; a document watermark is added at a target position of each page of the image file in the first text document to obtain a target text document, wherein the color of each pixel corresponding to the document watermark is any color within the first target color range. Thus, the document watermark is set to a gradient color or an irregular color, making it difficult to remove the document watermark, thereby solving the technical problem that the document watermark generated by the related technology is easy to remove, resulting in low document security.

[0040] The specific implementation steps of this embodiment are described in detail below.

[0041] As an optional implementation, in the technical solution provided in the above step S202 of the present invention, the method includes: obtaining a text document to be processed, and determining the document type of the text document to be processed, wherein the document type includes: image format and PDF format; when the document type of the text document to be processed is PDF format, converting the text document to be processed into a first text document in image format; when the document type of the text document to be processed is image format, determining that the text document to be processed is a first text document.

[0042] In this embodiment, since the text document is usually saved as a scanned copy in PDF format or a scanned copy in image format after adding a document watermark, when processing the text document, a software package such as Python's PyMuPDF package can be used to convert the PDF format text document into an image format text document first, so as to facilitate the subsequent adding of a document watermark to the image format text document.

[0043] For example, when a user sends a download request for text document one to the enterprise's knowledge management platform, the knowledge management platform can identify the text document information in text document one and determine whether text document one is in PDF format or image format. If text document one is in PDF format, Python's PyMuPDF package is used to convert each page of text document one into an image file, thereby obtaining text document one in image format.

[0044] As an optional implementation, in the technical solution provided in the above step S204 of the present invention, the method includes: determining the document watermark to be added, including: setting the watermark content and watermark direction of each page of the image file in the first text document according to a preset watermark rule.

[0045] In this embodiment, the watermark rule can be used to set the location and content of the document watermark within each page of the image file, and the watermark content can be set to copyright ownership information or downloader information according to actual needs. For example, when a user needs to download the text document, in order to distinguish the user of the text document and the person responsible for illegally distributing the text document, the watermark content of the text document can be set to the downloader's name and other related attribute information; when an individual text document needs to be uploaded to a public platform such as a web page, in order to prevent it from being stolen by others, the watermark content of the text document can be set to the owner's name and other related attribute information.

[0046] For example, when a user sends a download request for a text document to the enterprise's knowledge management platform, information that uniquely identifies the document downloader can be obtained. The information contains information that can uniquely identify the document downloader, such as the name, ID, mobile phone number, download time, etc. The knowledge management platform can use this information to generate a corresponding document watermark, such as: Zhang San 001587 15313033316 2022-05-26 00:12:25, to mark the document downloader, so that when an accident such as a document leak occurs, the person responsible for the illegal distribution can be held accountable afterwards.

[0047] As an optional implementation, in the technical solution provided in the above step S206 of the present invention, the method includes: for each page of the image file in the first text document, scanning each pixel at the target position in turn, and determining the color of the pixel; when the target color is white, determining to adjust the target color of the pixel to any color within the first target color range to obtain a document watermark, and adding the document watermark at the target position to obtain a target text document; when the target color is black, maintaining the target color of the pixel to obtain a document watermark, and adding the document watermark at the target position to obtain a target text document.

[0048] In this embodiment, in order to prevent the user from easily removing the document watermark processed at the target position, the color of each pixel is scanned in sequence. When the color of the pixel is white, that is, the RGB value is RGB (255, 255, 255), it means that the pixel corresponds to the document background. At this time, it is determined to adjust the target color of the pixel to any color within the first target color range to obtain the document watermark, and add the document watermark at the target position to obtain the target text document; when the color of the pixel is black, that is, the RGB value is RGB (0, 0, 0), it means that the pixel corresponds to the document content information. At this time, in order to prevent the document watermark from covering the document content information and affecting the user's viewing, the color of the document watermark is not changed, and the document watermark of the target color continues to be added at this position to obtain the target text document.

[0049] As an optional implementation, in the technical solution provided in the above step S206 of the present invention, the method also includes: when the RGB value of the pixel point is equal to the first value, determining that the target color is white; adjusting the target color of each pixel point at the target position to any color within the first target color range to obtain a document watermark, and adding the document watermark at the target position to obtain a target text document; or, setting the target color of each pixel point at the target position to a color within the first target color range in turn to obtain a document watermark, and adding the document watermark at the target position to obtain a target text document.

[0050] In this embodiment, when the RGB value of the pixel is equal to RGB (255, 255, 255), the target color is determined to be white, and the target color of each pixel at the target position is randomly set to any color within the first target color range, or the target color of each pixel at the target position is sequentially set to a color within the first target color range, so that the document watermark color is irregularly set and gradually set, so that the document watermark is no longer single, and it is prevented that others can easily remove the document watermark by setting the RGB value of the watermark to the RGB value of the document background color. Among them, the first target color range can be any color from RGB (90, 90, 90) to RGB (255, 255, 255).

[0051] For example, you can Figure 2 The color of the document watermark "Confidential" in the image file shown is set to any color within the first target color range corresponding to RGB (90, 90, 90) to RGB (255, 255, 255), making it difficult for the watermark removal software to distinguish between the document information content and the document watermark information. You can also cyclically use each color within the first target color range corresponding to RGB (90, 90, 90) to RGB (255, 255, 255) to set the color of the document watermark "Confidential" in the image file.

[0052] As an optional implementation, in the technical solution provided in the above step S206 of the present invention, the method also includes: when the RGB value of the pixel point is equal to the second value, determining that the target color is black; maintaining the target color of the pixel point to obtain a document watermark, and adding the document watermark at the target position to obtain a target text document.

[0053] In this embodiment, when the RGB value of a pixel is equal to RGB (0, 0, 0), the target color is determined to be black. This indicates that the pixel is a pixel corresponding to the document information content. In order to avoid watermarks of different colors from obscuring the document information content, the target color of the pixel is maintained to obtain a document watermark.

[0054] Furthermore, in order to prevent users from distinguishing between the document content and the document background color of the same black background, the embodiments of the present application also adjust the target color of each pixel corresponding to the document information content at the target position to any color within the second target color range when the target color is black, to obtain the target text document; or, set the target color of each pixel corresponding to the document information content at the target position to a color within the second target color range in turn, to obtain the target text document.

[0055] For example, for the original document content information, the target color of each pixel corresponding to the document information content at the target position can be adjusted to any gray within the second target color range corresponding to RGB (10, 10, 10) to RGB (110, 110, 110), or each color within the second target color range corresponding to RGB (10, 10, 10) to RGB (110, 110, 110) can be cyclically used to set the color of the document information content in the image file.

[0056] In an embodiment of the present application, by setting the color of a document watermark added to a text document to any color within a first target color range, or by setting the color of a document watermark added to a text document to colors within the first target color range in sequence, an irregular distribution or a gradient distribution of the document watermark color is achieved, thereby making it possible to distinguish between the document background color and the document watermark color; in addition, by setting the color of the document information content in the text document to any color within a second target color range, or by setting the color of the document information content in the text document to colors within the second target color range in sequence, an irregular distribution or a gradient distribution of the document information content color is achieved, thereby making it possible to distinguish between the document background color and the document information content color, thereby solving the technical problem that the document watermark generated by the related technology is easy to remove, resulting in low document security.

[0057] Example 2

[0058] According to an embodiment of the present application, a text document processing device for implementing the above-mentioned text document processing method is also provided. Figure 3 is a schematic diagram of the structure of an optional text document processing device according to an embodiment of the present application, such as Figure 3 As shown, the text document processing device at least includes an acquisition module 31, a determination module 32 and a generation module 33, wherein:

[0059] The acquisition module 31 is used to acquire a first text document in image format.

[0060] As an optional implementation, the acquisition module 31 can acquire the first text document in image format in the following manner: acquire the text document to be processed, and determine the document type of the text document to be processed, where the document type includes: image format and PDF format; when the document type of the text document to be processed is PDF format, convert the text document to be processed into a first text document in image format; when the document type of the text document to be processed is image format, determine that the text document to be processed is the first text document.

[0061] Since text documents are usually saved as scanned copies in PDF format or image format after adding document watermarks, when processing text documents, you can use Python's PyMuPDF package and other software packages to convert PDF format text documents into image format text documents first, so as to facilitate the subsequent addition of document watermarks to image format text documents.

[0062] For example, when a user sends a download request for text document one to the enterprise's knowledge management platform, the knowledge management platform can identify the text document information in text document one and determine whether text document one is in PDF format or image format. If text document one is in PDF format, Python's PyMuPDF package is used to convert each page of text document one into an image file, thereby obtaining text document one in image format.

[0063] The determination module 32 is used to determine the document watermark to be added, wherein the document watermark information includes: watermark content and watermark position.

[0064] As an optional implementation, the determination module 32 may determine the document watermark to be added in the following manner: Determining the document watermark to be added includes: setting the watermark content and watermark direction of each page of the image file in the first text document according to a preset watermark rule.

[0065] The watermark rules can set the location and content of the document watermark within each page of the image file. The watermark content can be set to copyright ownership information or downloader information according to actual needs. For example, when a user needs to download the text document, in order to distinguish the user of the text document and the person responsible for illegally distributing the text document, the watermark content of the text document can be set to the downloader's name and other related attribute information; when an individual text document needs to be uploaded to a public platform such as a web page, in order to prevent it from being stolen by others, the watermark content of the text document can be set to the owner's name and other related attribute information.

[0066] For example, when a user sends a download request for a text document to the enterprise's knowledge management platform, information that uniquely identifies the document downloader can be obtained. The information contains information that can uniquely identify the document downloader, such as the name, ID, mobile phone number, download time, etc. The knowledge management platform can use this information to generate a corresponding document watermark, such as: Zhang San 001587 15313033316 2022-05-26 00:12:25, to mark the document downloader, so that when an accident such as a document leak occurs, the person responsible for the illegal distribution can be held accountable afterwards.

[0067] The generating module 33 is used to add a document watermark at a target position of each page of the image file in the first text document to obtain a target text document, wherein the target color of each pixel point corresponding to the document watermark is any color within the first target color range.

[0068] As an optional implementation, the generation module 33 can obtain the target text document in the following manner: for each page of the image file in the first text document, scan each pixel at the target position in turn and determine the color of the pixel; when the target color is white, determine to adjust the target color of the pixel to any color within the first target color range to obtain a document watermark, and add the document watermark at the target position to obtain the target text document; when the target color is black, maintain the target color of the pixel to obtain a document watermark, and add the document watermark at the target position to obtain the target text document.

[0069] In order to prevent users from easily removing the document watermark processed at the target position, choose to scan the color of each pixel in turn. When the color of the pixel is white, that is, the RGB value is RGB (255, 255, 255), it means that the pixel corresponds to the document background. At this time, it is determined to adjust the target color of the pixel to any color within the first target color range to obtain the document watermark, and add the document watermark at the target position to obtain the target text document; when the color of the pixel is black, that is, the RGB value is RGB (0, 0, 0), it means that the pixel corresponds to the document content information. At this time, in order to prevent the document watermark from covering the document content information and affecting the user's viewing, the color of the document watermark is not changed, and the document watermark of the target color continues to be added at this position to obtain the target text document.

[0070] Optionally, when the RGB value of the pixel point is equal to the first value, the target color is determined to be white; the target color of each pixel point at the target position is adjusted to any color within the first target color range to obtain a document watermark, and the document watermark is added at the target position to obtain a target text document; or, the target color of each pixel point at the target position is set to a color within the first target color range in turn to obtain a document watermark, and the document watermark is added at the target position to obtain a target text document.

[0071] In this embodiment, when the RGB value of the pixel is equal to RGB (255, 255, 255), the target color is determined to be white, and the target color of each pixel at the target position is randomly set to any color within the first target color range, or the target color of each pixel at the target position is sequentially set to a color within the first target color range, so that the document watermark color is irregularly set and gradually set, so that the document watermark is no longer single, and it is prevented that others can easily remove the document watermark by setting the RGB value of the watermark to the RGB value of the document background color. Among them, the first target color range can be any color from RGB (90, 90, 90) to RGB (255, 255, 255).

[0072] Optionally, when the RGB value of the pixel is equal to the second value, the target color is determined to be black; the target color of the pixel is maintained to obtain a document watermark, and the document watermark is added at the target position to obtain a target text document.

[0073] In this embodiment, when the RGB value of a pixel is equal to RGB (0, 0, 0), the target color is determined to be black. This indicates that the pixel is a pixel corresponding to the document information content. In order to avoid watermarks of different colors from obscuring the document information content, the target color of the pixel is maintained to obtain a document watermark.

[0074] Furthermore, in order to prevent users from distinguishing between the document content and the document background color of the same black background, the embodiments of the present application also adjust the target color of each pixel corresponding to the document information content at the target position to any color within the second target color range when the target color is black, to obtain the target text document; or, set the target color of each pixel corresponding to the document information content at the target position to a color within the second target color range in turn, to obtain the target text document.

[0075] For example, for the original document content information, the target color of each pixel corresponding to the document information content at the target position can be adjusted to any gray within the second target color range corresponding to RGB (10, 10, 10) to RGB (110, 110, 110), or each color within the second target color range corresponding to RGB (10, 10, 10) to RGB (110, 110, 110) can be cyclically used to set the color of the document information content in the image file.

[0076] It should be noted that each module in the text document processing device in the embodiment of the present application corresponds one-to-one to each implementation step of the text document processing method in Example 1. Since a detailed description has been given in Example 1, some details not reflected in this embodiment can be referred to Example 1 and will not be repeated here.

[0077] Example 3
