Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and the accompanying drawings are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For a better understanding of the embodiments of the present application, some nouns or translations of terms that appear during the description of the embodiments of the present application are explained first as follows:
RGB values: RGB refers to the optical three primary colors, red (Red), green (Green) and Blue (Blue), respectively, and RGB values are specifically reflecting luminance (i.e., intensity values), which are generally expressed by integers of 0 to 255, wherein 255 corresponds to the maximum luminance and 0 corresponds to the minimum luminance, and thus R, G, B each has 256-level luminance.
Example 1
For documents with large business value or confidential documents in enterprises or organizations, such as business contracts, agreement documents, personnel qualification documents in organizations and the like, protection is needed to avoid malicious leakage of a knowledge management platform of the enterprises or organizations.
At present, a commonly adopted method is to mark a document through a data watermarking technology so as to distinguish a user of the document and a responsible person for illegal distribution, and the method is used for performing post-mortgage on the responsible person for illegal distribution. However, since such watermarked documents are typically stored in the form of scanned items, their file types are typically divided into two categories, PDF format and image format.
For the PDF format document, the watermark can be added in the PDF format document through a PDF Reader, such as an Acrobat Reader and a Fuxin Reader, but the user can also use the same software or the software with the same brand and a higher-order version to remove the document watermark in the PDF format document. Or a large number of text boxes are inserted into the PDF format document, watermark text information is input into the text boxes and stored, but the method only works for Acrobat Reader and Fuxin readers without editing rights, otherwise, related personnel with editing rights can easily remove the watermark through the PDF Reader software. Whereas for documents in image format, image editing software may be used to form the watermark image shown in fig. 1. However, since the watermark color and the background color of the document are distinguished in detail, a user can acquire the RGB value of the watermark image through the image file and modify the RGB value into the background color of the document, so that the watermark information is easily removed.
Thus, the document watermark generated by the related art is easy to clear, resulting in lower document security.
In order to solve the above-mentioned problems, the embodiments of the present application provide a text document processing method, which makes it difficult to eliminate a document watermark by setting the document watermark to a gradation color or an irregular color.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
FIG. 2 is a flow chart of an alternative text document processing method according to an embodiment of the present application, as shown in FIG. 2, the method at least includes steps S202-S206, wherein:
step S202, a first text document in an image format is acquired.
In the technical solution provided in the above step S202 of the present invention, the first text document in the image format may be a scanned document of a text document such as a business contract, a corporate qualification, a protocol contract, etc., where the image format may be, but is not limited to, a JPG image or a PNG image, etc., and is not limited herein.
Step S204, determining a document watermark to be added, wherein the document watermark information comprises: watermark content and watermark location.
In the technical scheme provided in the step S204, the document watermark to be added is used for writing the attribution information or the information of the downloader for the document on the premise of ensuring that the reading of the document is not influenced, so as to play a role in protecting the document copyright and avoiding the leakage of the document caused by secondary forwarding.
In step S206, a document watermark is added at a target position of each page of image file in the first text document, so as to obtain a target text document, wherein the color of each pixel point corresponding to the document watermark is any color in the first target color range.
In the technical scheme provided in the step S206, the color of each pixel point corresponding to the watermark of the document can be any color within the first target color range, wherein the first target color needs to be distinguished from the background (i.e. white) of the document, so that the user is prevented from obtaining the RGB value of the watermark image from the image file and modifying the RGB value into the background color of the document, and the user can easily clear the watermark of the document.
In the embodiment of the application, a first text document in an image format is acquired; determining a document watermark to be added, wherein the document watermark information comprises the following steps: watermark content and watermark orientation; and adding a document watermark at a target position of each page of image file in the first text document to obtain the target text document, wherein the color of each pixel point corresponding to the document watermark is any color in a first target color range. Therefore, the document watermark is set to be in gradual change color or irregular color, so that the document watermark is difficult to eliminate, and the technical problem that the document watermark generated by the related technology is easy to clear, and the document security is low is solved.
The specific implementation steps of this embodiment are described in detail below.
As an optional implementation manner, in the technical solution provided in step S202 of the present invention, the method includes: acquiring a text document to be processed, and judging the document type of the text document to be processed, wherein the document type comprises: 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; and when the document type of the text document to be processed is in the image format, determining that the text document to be processed is a first text document.
In this embodiment, after the document watermark is added to the text document, the document watermark is usually saved in a PDF format scanner or an image format scanner, so when the text document is processed, a software package such as PyMuPDF package of Python can be used to convert the PDF format text document into the image format text document first, so that the document watermark can be conveniently added to the image format text document later.
For example, when a user sends a download request for a first text document to the knowledge management platform of the enterprise, the knowledge management platform may identify text document information in the first text document and determine whether the first text document is in PDF format or image format, and if the first text document is in PDF format, use the PyMuPDF package of Python to convert each page of the first text document into an image file, thereby obtaining the first text document in image format.
As an optional implementation manner, in the technical solution provided in step S204 of the present invention, the method includes: determining a document watermark to be added, comprising: and setting watermark content and watermark direction of each page of image file in the first text document according to a preset watermark rule.
In this embodiment, the watermark rule may set the position and content of the watermark of the document in each page of the image file, and may set the watermark content as copyright attribution information or information of a downloader 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 from a responsible person who illegally distributes the text document, the watermark content of the text document may be set as related attribute information such as a name of the downloader; when a text document to which an individual belongs needs to be uploaded to a public platform such as a webpage, in order to avoid being stolen by other people, watermark content equipment of the text document can be used as related attribute information such as the name of the attribution.
For example, when the user sends a download request for the text document one to the knowledge management platform of the enterprise, information that can uniquely identify the document downloadable may be obtained, where the information includes a name, an ID, a mobile phone number, a download time, and the like that can uniquely identify the document downloadable. The knowledge management platform may generate corresponding document watermarks with such information as: zhang three 001587 15313033316 2022-05-26 00:12:25 is used for marking a document download person so as to perform post-responsibility following the illicit distribution responsibility person when accidents such as document leakage occur.
As an optional implementation manner, in the technical solution provided in step S206 of the present invention, the method includes: for each page of image file in the first text document, scanning each pixel point at the target position in sequence, and determining the color of the pixel point; when the target color is white, determining to adjust the target color of the pixel point to any color in a first target color range to obtain a document watermark, and adding the document watermark at a target position to obtain a target text document; and when 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.
In the embodiment, in order to avoid that a user easily removes the document watermark processed at the target position, selecting to sequentially scan the colors of each pixel point, when the color of the pixel point is white, namely the RGB value is RGB (255, 255, 255), indicating that the pixel point corresponds to the document background, determining to adjust the target color of the pixel point to any color in the first target color range at this time to obtain the document watermark, and adding the document watermark at the target position to obtain the target text document; when the color of the pixel point is black, namely the RGB value is RGB (0, 0), the pixel point is corresponding to the document content information, and at the moment, in order to avoid the document watermark covering the document content information and affecting the viewing of a user, the color of the document watermark is not changed, and the document watermark with the target color is continuously added at the position, so that the target text document is obtained.
As an optional implementation manner, in the technical solution provided in step S206 of the present invention, the method further includes: when the RGB value of the pixel point is equal to the first numerical value, determining that the target color is white; adjusting the target color of each pixel point at the target position to be any color in a 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 sequentially setting the target color of each pixel point at the target position as the color in the first target color range to obtain the document watermark, and adding the document watermark at the target position to obtain the target text document.
In this embodiment, when the RGB values of the pixel points are equal to RGB (255, 255, 255), the target color is determined to be white, and the target color of each pixel point at the target position is randomly set to any color within the first target color range, or the target color of each pixel point at the target position is sequentially set to the 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 the document watermark is prevented from being easily removed by others by setting the RGB values of the watermark to the RGB values of the document background color. The first target color range may be any color from RGB (90, 90, 90) to RGB (255, 255, 255).
For example, the color of the document watermark "confidential" in the image file shown in fig. 2 may be set to any one of the colors in the first target color range corresponding to RGB (90, 90, 90) to RGB (255, 255, 255), making it difficult for the watermarking software to distinguish the document information content from the document watermark information, or the color of the document watermark "confidential" in the image file may be set for each of the colors in the first target color range corresponding to RGB (90, 90, 90) to RGB (255, 255, 255) in a cyclic manner.
As an optional implementation manner, in the technical solution provided in step S206 of the present invention, the method further includes: when the RGB value of the pixel point is equal to the second value, determining that the target color is black; and 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.
In this embodiment, when the RGB value of the pixel is equal to RGB (0, 0), it is determined that the target color is black, and this indicates that the pixel is a pixel corresponding to the document information content, so as to avoid the watermark of different colors from blocking the document information content, and therefore, the target color of the pixel is continuously maintained, so as to obtain the document watermark.
Further, in order to prevent a user from distinguishing black background document content and document background color of the same color, when the target color is black, the embodiment of the application adjusts the target color of each pixel point corresponding to the document information content at the target position to any color in a second target color range to obtain a target text document; or sequentially setting the target color of each pixel point corresponding to the document information content at the target position to be the color in the second target color range to obtain the target text document.
For example, for the original document content information, the target color of each pixel point corresponding to the document information content at the target position may be adjusted to any gray color in the second target color range corresponding to RGB (10, 10, 10) to RGB (110, 110, 110), or the color of the document information content in the image file may be set for each color in the second target color range corresponding to RGB (10, 10, 10) to RGB (110, 110, 110) by recycling.
In the embodiment of the application, the irregular distribution or gradual distribution of the document watermark color is realized by setting the document watermark color added to the text document as any color within a first target color range or sequentially setting the document watermark color added to the text document as the color within the first target color range, so that the document background color and the document watermark color can be distinguished; in addition, the color of the document information content in the text document is set to be any color in the second target color range, or the color of the document information content in the text document is sequentially set to be the color in the second target color range, so that irregular distribution or gradual distribution of the document information content is realized, irregular distribution or gradual distribution of the document information content color is realized, the document background color and the document information content color can be distinguished, and the technical problem that the document watermark generated by the related technology is easy to clear, and the document security is low is solved.
