Description

Technical Field

[0001] This application relates to the technical field of security management, and particularly relates to a device security management method, apparatus, electronic device, and storage medium. Background Art

[0002] An image forming apparatus is a device that forms an image on a recording medium through an imaging principle, such as a printer, copier, fax machine, multifunctional image production and copying apparatus, electrophotographic apparatus, and any other similar apparatus. Among them, the common recording medium is paper, and once confidential information is presented on the paper, there is a certain possibility of leakage. Therefore, the control of the copying security of the image forming apparatus is particularly important.

[0003] In the related art, when a user selects to copy, the image forming apparatus saves the scanned image for the administrator to review the copied content.

[0004] However, saving the scanned image in the related art occupies a large amount of memory of the image forming apparatus, and it takes a long time for the administrator to review the scanned image, affecting work efficiency.

[0005] It should be noted that the information disclosed in the background art part of this application is only intended to deepen the understanding of the general background art of this application, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0006] In view of this, this application provides a device security management method, apparatus, electronic device, and storage medium to facilitate solving the problem that saving the scanned image in the prior art occupies a large amount of memory of the image forming apparatus, and it takes a long time for the administrator to review the scanned image, affecting work efficiency.

[0007] In a first aspect, an embodiment of this application provides a device security management method applied to an image forming apparatus. The method includes: Obtain a scanned image; Generate a summary and log information according to the content of the scanned image, and create a retention log according to the summary and the log information; Perform privacy processing on the privacy information in the scanned image, and mark the important information in the scanned image to obtain a retention image, where the important information is the information revealing the content of the scanned image; Save the retention log and the retention image to a retention server.

[0008] In the embodiments of the present application, the archived log includes the summary and log information corresponding to the scanned image. When generating the summary and log information, there is no need to connect to the network, which ensures the security of the content. When the administrator reviews the scanned image, the general content of the entire scanned image can be obtained only through the archived log, without the administrator having to view the specific content of each scanned image one by one, improving the review efficiency. Moreover, the content summary in the archived log does not contain privacy information, which can avoid leaking privacy information to the administrator, thereby ensuring the security of privacy information. In addition, the archived log and the archived image are saved to the archived server, and the archived server is used to save the log file and the archived image, without occupying the memory of the image forming device.

[0009] In a possible implementation manner, the method further includes: If it is recognized that there is dangerous and sensitive information in the scanned image, the archived log, the archived image, and a prompt message are sent to the administrator; The dangerous and sensitive information includes illegal information and / or information that endangers public safety; The prompt message is used to prompt the administrator that there is the dangerous and sensitive information in the scanned image.

[0010] In the embodiments of the present application, if it is recognized that there is dangerous and sensitive information in the scanned image, the archived log and the archived image are sent to the administrator, so as to prompt the user that there is dangerous and sensitive information in this scanned image, so that the administrator can handle this situation.

[0011] In a possible implementation manner, the privacy processing of the privacy information in the scanned image and the marking of the important information in the scanned image to obtain the archived image include: Determine the coordinates of the privacy information and the important information in the scanned image; Perform privacy processing on the privacy information according to the coordinates of the privacy information; Perform marking processing on the important information according to the coordinates of the important information.

[0012] In the embodiments of the present application, first determine the coordinates of the privacy information and the important information, and perform privacy processing on the privacy information according to the coordinates of the privacy information, and perform marking processing on the important information according to the coordinates of the important information. It can be understood that determining the coordinates of the privacy information and the important information in advance can quickly mark the privacy information and the important information, and after marking the privacy information and the important information, it is more convenient for the manager to view the information in the scanned image.

[0013] In a possible implementation manner, the saving of the archived log and the archived image to the archived server includes: Output interaction information through a display unit, where the interaction information is used to prompt the user that the administrator will be notified of the existence of privacy information in the scanned image and obtain an operation instruction selected by the user; Save the archived image to the archived server or stop the image formation job according to the operation instruction.

[0014] In an embodiment of the present application, the user is prompted that the administrator will be notified of the existence of privacy information in the scanned image. If the user chooses to continue, the archived log and the archived image will be saved to the archived server. It can be understood that through information interaction, the operation instruction of the user can be obtained while prompting the user, so that the processing result meets the expectations of the user. When the user chooses to cancel archiving, the image formation job is directly stopped, which can ensure that all images executed for the image formation job are archived, thus ensuring information security.

[0015] In a possible implementation manner, the saving the archived log and the archived image to the archived server includes: Compress the archived image; Save the archived log and the compressed archived image to the archived server.

[0016] In an embodiment of the present application, the archived image is compressed first and the compressed archived image is sent to the archived server. It can be understood that the compressed archived image occupies less space and can avoid wasting resources.

[0017] In a possible implementation manner, the compressing the archived image includes: Reduce the resolution of the archived image and convert the archived image into a grayscale image.

[0018] It can be understood that reducing the resolution and converting the image into a grayscale image can effectively reduce the occupied space of the archived image.

[0019] In a possible implementation manner, the compressing the archived image further includes: Crop the blank area in the archived image and delete the blank page to obtain a remaining image, where the blank area is an area with a blank area greater than or equal to a preset area threshold; Merge the remaining images and perform typesetting processing on the remaining images.

[0020] In an embodiment of the present application, deleting the blank area and the blank page in the archived image can further reduce the occupied space of the archived image to a greater extent, and the blank area in the archived image is determined whether to be deleted through a preset area threshold. It can be understood that setting the preset area threshold is to avoid deleting too large an area, thereby ensuring the integrity of the image and retaining the interval between each image.

Detailed implementation manners

[0027] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0028] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without any creative efforts belong to the scope of protection of the present application.

[0029] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0030] It should be understood that the term " / and / " used herein is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0031] For ease of understanding, the embodiments of the present application provide a schematic diagram of an application scenario.

[0032] See Figure 1 , a schematic diagram of an application scenario provided by the embodiments of the present application. As Figure 1As shown in the figure, the image forming apparatus 100 includes a scanning area 1001, a paper outlet 1002, and a display unit 1003. When a user needs to copy a document, the document to be scanned is placed on the scanning area 1001, and a copy instruction is input into the image forming apparatus 100 through the display unit 1003. After receiving the copy instruction, the image forming apparatus 100 scans the document in the scanning area 1002 to obtain a scanned document, and then presents the scanned document on a recording medium and discharges the recording medium from the paper outlet 1002, thereby completing the copying process. The display unit includes, but is not limited to, the display module of the image forming apparatus and electronic devices such as webpages and display screens outside the image forming device for displaying interaction information and other information.

[0033] It should be noted that Figure 1 the image forming apparatus shown in the figure is only an exemplary illustration. In fact, an image forming apparatus is a device that forms an image on a recording medium through an imaging principle, such as a printer, a copier, a fax machine, a multi-functional image production and copying apparatus, an electrophotographic apparatus, and any other similar apparatus. It should not be regarded as a limitation on the protection scope of the present application.

[0034] In practical applications, the common recording medium is paper. Once confidential information is presented on paper, there is a certain possibility of leakage. Therefore, it is particularly important to control the copying security of the image forming apparatus.

[0035] In the related art, when a user selects to copy, the image forming apparatus saves the scanned image for the administrator to review the copied content.

[0036] However, saving the scanned image in the related art will occupy a large amount of memory of the image forming apparatus, and it takes a long time for the administrator to review the scanned image, affecting work efficiency.

[0037] In view of the above problems, the embodiments of the present application provide a security management method. The retention log in the embodiments of the present application includes the summary and log information corresponding to the scanned image. When generating the summary and log information, there is no need to connect to the network, ensuring the security of the content. When the administrator reviews the scanned image, only through the retention log, the general content of the entire scanned image can be obtained, without the administrator viewing the specific content of each scanned image one by one, improving the review efficiency. Moreover, the content summary in the retention log does not contain privacy information, which can avoid leaking privacy information to the administrator, thereby ensuring the security of privacy information. In addition, the retention log and the retention image are saved to a retention server, and the retention server is used to save the log file and the retention image, without occupying the memory of the image forming apparatus. Details will be described in combination with the accompanying drawings and specific embodiments below.

[0038] See Figure 2, which is a schematic flowchart of a device security management method provided by an embodiment of the present application. As Figure 2 shown, it mainly includes the following steps.

[0039] Step S201: Obtain a scanned image.

[0040] Specifically, the user can pre-place the document to be copied in the scanning area of the scanning device and input a copy instruction through the display unit. After receiving the copy instruction, the image forming device obtains the scanned image in the scanning area through the scanning device.

[0041] It should be noted that the scanning device can be a separate device externally placed on the image forming device or built into the image forming device.

[0042] Step S202: Generate a summary and log information based on the content of the scanned image, and create a retention log according to the summary and log information.

[0043] Specifically, the device security management device understands the content of the scanned image, generates a summary and log information, and creates a retention log according to the summary and log information. Among them, the summary is the theme of the content of the scanned image, and the log information includes but is not limited to the executor of this operation, the copying time, the copying parameters, and the number of copied pages. The retention log at least includes the content theme of the scanned image, the executor of this operation, the copying time, the copying parameters, and the number of copied pages.

[0044] Exemplarily, at 8:00 am on Wednesday, March 12, 2025, user A logged in to his / her account on the image forming device and copied a labor contract. The device security management device on the image forming device can obtain that the executor of this operation is user A, the copying time is 8:00 am on Wednesday, March 12, 2025, the copying parameters are default parameters, and the number of copied pages is 1 page, so as to generate log information containing the above information. And when the user copies, after the image forming device obtains the content of the scanned image, it can generate a summary according to the content of the scanned image, that is, the labor contract. The device security management device can create a retention log according to the above summary and log information for the administrator to review.

[0045] In a possible implementation manner, the content of the scanned image is recognized by the AI module, and a summary is generated according to the content of the scanned image. The AI module combines computer vision and natural language processing technologies and can understand the content of the scanned image.

[0046] The AI module can be set outside the device security management device (i.e., in the cloud server), and the image forming device needs to be connected to the network to use the AI module; the AI module can also be built into the device security management device, so that on the basis of regular maintenance and upgrade, the AI module can be used offline to ensure data security.

[0047] In practical applications, some people may use an image forming device to copy documents that are illegal or harmful to public safety. If such information is only marked and waiting for the administrator to review, it may lead to relatively serious consequences. Therefore, in the embodiments of the present application, if dangerous sensitive information is identified in the scanned image, a retained log, a retained image, and a prompt message will be immediately sent to the administrator. Among them, the dangerous sensitive information includes illegal information and information harmful to public safety, and the prompt message is used to prompt the administrator that there is dangerous sensitive information in the scanned image, facilitating the administrator to process it in a timely manner and preventing the leakage of dangerous sensitive information.

[0048] In a possible implementation manner, the AI module can identify the coordinates and range of the dangerous sensitive information. The device security management device performs special processing on the dangerous sensitive information determined by the AI module, uses the processed scanned image as an attachment, and uses the summary generated by the AI module as the content of the email, generates an email and sends it to the administrator's email box. Among them, the special processing includes, but is not limited to, technical means such as highlighting and boxing.

[0049] It can be understood that when dangerous sensitive information is identified, immediately sending this copying task to the administrator can enable the administrator to discover abnormal situations in a timely manner and make corresponding processing, thereby avoiding serious consequences.

[0050] In addition, in a possible implementation manner, the administrator can control whether to enable the device security management function. Specifically, the administrator can select to enable or disable the device security management function through an administrator visual terminal interface such as a webpage, an administrator APP, or an administrator page of the display unit of the image forming device. If the administrator enables the device security management function, when the user uses the image forming device to scan an image, the device security management method provided in the embodiments of the present application will be automatically executed. In the embodiments of the present application, when the administrator does not set whether to enable the device security management function, the device security management function is enabled by default.

[0051] Step S203: Perform privacy processing on the privacy information in the scanned image, and mark the important information in the scanned image to obtain a retained image.

[0052] Specifically, the device security management device can screen out the privacy information and important information in the scanned image, perform privacy processing on the privacy information, and mark the important information, thereby obtaining a retained image. Among them, the important information is the information that reveals the content of the scanned image and is the indicative information that differentiates the scanned image from other documents. For example, the "labor contract" in the above example. The privacy information includes, but is not limited to, names and ID numbers. The privacy processing includes technical means such as blurring, covering, etc. The means of marking important information include boxing, changing the font color, changing the text background color, and adding underlines, etc.

[0053] It should be noted that the means of marking important information may or may not be the same as the special processing of dangerous and sensitive information. If the dangerous and sensitive information is searched for and marked before screening privacy information and important information, the special processing of the dangerous and sensitive information may be the same as the means of marking important information; if the dangerous and sensitive information is searched for and marked while screening privacy information and important information, in order to avoid confusing the two types of information and ensure that the administrator can quickly view the dangerous and sensitive information, the special processing of the dangerous and sensitive information is set to be different from the means of marking important information.

[0054] It can be understood that by performing privacy processing on privacy information, even administrators cannot view the user's privacy information, thus better protecting the user's privacy, while marking important information can speed up the administrator's review speed, thereby improving the administrator's work efficiency.

[0055] In a possible implementation, the AI module determines the coordinates of privacy information and important information in the scanned image, performs privacy processing on the privacy information according to the coordinates of the privacy information, and performs marking processing on the important information according to the coordinates of the important information.

[0056] It should be noted that the coordinates in the embodiments of the present application are coordinate ranges. For example, the second character in the second row to the sixth character in the second row.

[0057] It can be understood that while the AI module screens privacy information and important information, recording the coordinates of the privacy information and the important information can ensure that the scanned image is traversed only once and does not require multiple screenings, thereby reducing the data processing steps and improving the work efficiency.

[0058] Step S204: Save the retained log and the retained image to the retention server.

[0059] In the embodiments of the present application, the retention server is a server outside the image forming device. Saving the retained log and the retained image to the retention server can not only save the retained log and the retained image, but also avoid occupying the memory of the image forming device. At the same time, the retention server can also be built into the image forming device, which can speed up the data transmission speed and ensure the timeliness of the data.

[0060] For the sake of simplicity of expression, hereinafter, the retained log and the retained picture are collectively referred to as retained information.

[0061] In a possible implementation, interactive information is output through a display unit, and the user is prompted through the interactive information that the administrator will be notified that there is privacy information and / or dangerous sensitive information in the scanned image, and an operation instruction selected by the user is obtained. If the operation instruction indicates to continue the copying operation, the archived information is saved to an archive server, and the administrator is notified that the scanned image contains privacy information and / or dangerous sensitive information; if the operation instruction indicates cancellation, the image forming operation is stopped.

[0062] Specifically, as long as the administrator is notified that there is privacy information and / or dangerous sensitive information in the scanned image, the image forming device will generate archived information and save it in the archive server to ensure the comprehensiveness of information monitoring and prevent privacy information and / or dangerous sensitive information from being missed during auditing.

[0063] Exemplarily, the interactive information can be, but is not limited to, a notification such as "The copied content contains privacy information. The administrator will be notified soon. Please confirm whether to continue" that prompts the administrator that the copied content contains privacy information. If the user selects to continue, the archived information is saved to the archive server.

[0064] It can be understood that through information interaction, the operation instruction of the user can be obtained while prompting the user, so that the processing result meets the user's expectations.

[0065] In a possible implementation, if the operation instruction selected by the user indicates cancellation, when the image forming operation is stopped, no archived information is generated. It can be understood that directly stopping the image forming operation when the user selects to cancel archiving can ensure that all images that perform the image forming operation are archived, thereby ensuring the security of user information and respecting the privacy of users.

[0066] In addition, although the archived information is saved to the archive server, the archived information includes an archive log and an archived image. Directly saving the archived information may require a large amount of data processing and take a long time.

[0067] To address this problem, in the embodiments of the present application, the archived image is first compressed, and then the archive log and the compressed archived image are saved to the archive server. It can be understood that the compressed archived image occupies less space, can avoid wasting resources, and the compressed archived image requires less data processing, can save data processing time, and improve work efficiency.

[0068] In a possible implementation, the way to compress the archived image is to reduce the resolution of the archived image and convert the archived image into a grayscale image.

[0069] Specifically, the device safety management device is equipped with a function to reduce the resolution, and methods such as the adjacent difference algorithm, bilinear interpolation method, and bicubic interpolation method are used to reduce the resolution of the scanned image. Moreover, the device safety management device is equipped with an image grayscale processing function, and methods such as the weighted average algorithm are used to achieve grayscale processing of color images, thereby reducing the consumption of the storage medium for storing images.

[0070] Exemplarily, refer to Figure 3 , which is a schematic diagram of grayscale processing of a scanned image provided by an embodiment of the present application. As Figure 3 shown, the left image is the scanned image before grayscale processing, and the right image is the scanned image after grayscale processing. Obviously, the scanned image after grayscale processing has fewer colors, which is more convenient for the device safety management device to store the scanned image, thereby reducing the consumption of the storage medium for storing images.

[0071] In a possible implementation manner, the operation of compressing and retaining the image further includes cropping the blank area in the retained image and deleting blank pages to obtain a remaining image, where the blank area is an area with a blank area greater than or equal to a preset area threshold, merging the remaining images, and performing typesetting processing on the remaining images.

[0072] Specifically, the device safety management device is equipped with an image blank area recognition function, and methods such as grayscaling, binarization, denoising, contour, region extraction, and calculation are used to identify the entire segment / entire row of blank areas and perform cropping or deletion processing on them.

[0073] Specifically, the preset area threshold is the minimum interval between each image to ensure the integrity of the image and the convenience of user reading.

[0074] Exemplarily, refer to Figure 4 , which is a schematic diagram of blank area removal processing of a retained image provided by an embodiment of the present application. As Figure 4 shown, the left image is the scanned image before blank area removal processing, and the right image is the scanned image after blank area removal processing. In this example, the color scanned image is directly subjected to blank area removal processing, and while removing the blank area of the scanned image, the scanned image is converted into a grayscale image. Of course, in actual applications, the color scanned image can be first converted into a grayscale image, and then the blank area of the grayscale image is removed. The embodiments of the present application do not make specific limitations on this.

[0075] Exemplarily, refer to Figure 5 , which is a schematic diagram of typesetting processing of a retained image provided by an embodiment of the present application. As Figure 5As shown in a of , the left image is the scanned image before typesetting processing, and the right image is the scanned image after typesetting processing. In this example, 4 independent and color scanned images are grayscale processed and the blank areas therein are removed, and the processed scanned images are re-typeset into 1 archived image. Of course, in the embodiments of the present application, there are many page typesetting methods. For example, Figure 5 As shown in b of , it can be typeset vertically, and the embodiments of the present application do not make specific limitations thereto.

[0076] In the embodiments of the present application, deleting the blank areas and blank pages in the archived image can greatly reduce the occupied space of the archived image, and whether the blank areas in the archived image should be deleted is determined by a preset area threshold. It can be understood that setting the preset area threshold is to avoid deleting an overly large area, so as to ensure the integrity of the image and retain the intervals between each image.

[0077] Corresponding to the above embodiments, the present application also provides a schematic flowchart of another device security management method.

[0078] See Figure 6 , which is a schematic flowchart of another device security management method provided by the embodiments of the present application. As Figure 6 shown, it mainly includes the following steps.

[0079] Step S601: Start.

[0080] Step S602: Obtain a scanned image.

[0081] Step S603: Determine whether the copy archiving function is enabled.

[0082] Specifically, the copy archiving function is the device security management method. If so, execute Step S604; if not, execute Step S607.

[0083] Step S604: Process the archived image.

[0084] Step S605: Save the archived image and the archiving log to the archiving server.

[0085] Step S606: Archive and copy.

[0086] Step S607: Process the scanned image.

[0087] Step S608: Print the processed scanned image.

[0088] The specific content involved in the embodiments of the present application can be referred to the description in the above Figures 2 to 5 shown embodiments. For the sake of brevity of description, it will not be elaborated herein.

[0089] Corresponding to the above embodiments, the present application further provides a device security management device.
