Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a document printing safety management system, method and storage medium. Background Art

[0002] In the field of digital printing management technology, data analysis technology can be used to analyze printing management data. Since printing management data is easily affected by factors such as personnel identity authentication, the accuracy and reliability of printing data will decrease, affecting the effectiveness and security of the digital printing management system. It may lead to unauthorized personnel printing, and may also cause problems such as tampering of printed content, file loss or misprinting, thereby further affecting the compliance, data security and operational efficiency of printing management.

[0003] Prior art, such as the invention patent announcement with announcement number: CN111401858B, discloses a safety tool certificate management and printing system and method based on WEB and cloud applications. The system disclosed in the invention replaces manual handwriting of safety tool certificates, avoids errors caused by manual handwriting, and shortens the test time occupied by handwritten labels. The management printing system disclosed in the invention includes a user layer, a service layer, a control layer, and a data layer; the host end is wirelessly connected to the printer; the host end simulates the operation of the printer, intercepts the data and control signals transmitted from the parallel port of the host end, and transmits them to the printer via a Bluetooth wireless connection; the single-chip microcomputer of the printer simulates the host end to control the printer according to the received Bluetooth data; the Bluetooth of the host end acts as a master device to query and initiate a connection, and the Bluetooth of the printer acts as a slave device to wait for the establishment of a connection.

[0004] Prior art, such as a written document generation method, apparatus, terminal device and storage medium disclosed in the invention patent announcement with announcement number: CN108460575B, includes: receiving a written document reissue request sent by a user from a client; setting the written document reissue status to a start status, and sending the start status to the client; performing a legality check on the written document reissue application information, updating the written document reissue status to a verification status, and sending the verification status to the client; if the legality check passes, reissue the written document using a preset written document generation method, and at the same time, updating the written document reissue status to a processing status, and sending the processing status to the client; if the written document reissue is successful, printing the reissued written document; if the written document is printed successfully, updating the written document reissue status to a completion status, and sending the completion status to the client.

[0005] Combining the above solutions, it is found that in the current field of digital management technology for document printing, usually only the printing data is monitored and analyzed. However, different printed documents have different printing requirements. Analyzing only the quality cannot timely suppress the quality problems that occur during the printing process, which not only affects the accuracy and security of document printing management, but also poses risks such as data leakage, misoperation, and unauthorized printing, affecting the protection of information security, and ultimately may lead to problems such as leakage of sensitive information and waste of resources. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a document printing security management system, method, and storage medium, which can effectively solve the problems involved in the above background technology.

[0007] To achieve the above objectives, the first aspect of the present invention is realized through the following technical solutions: A document printing security management system includes a printing permission authentication module for performing printing permission authentication on the person requesting printing. After successful authentication, the person requesting printing is recorded as an authorized person.

[0008] A printing pre-execution judgment module for collecting the characteristic data corresponding to the electronic file transmitted by the authorized person, and synchronously retrieving the historical operation and maintenance data of the printer for comprehensive processing to obtain the document printing security efficiency evaluation value of the printer, thereby performing a printing pre-execution judgment to obtain a printing pre-execution judgment result, and the printing pre-execution judgment result is to execute printing or not to execute printing.

[0009] A printing control and processing module for analyzing based on the printing pre-execution judgment result. If the printing pre-execution judgment result is to execute printing, it reminds that the electronic file transmitted by the authorized person can be printed immediately. If the printing pre-execution judgment result is not to execute printing, it retrieves the operation data of each idle printer currently and screens and adapts the printer to perform the printing process of the electronic file of the authorized person.

[0010] Further, the specific process of synchronously retrieving the historical operation and maintenance data of the printer for comprehensive processing to obtain the document printing security efficiency evaluation value of the printer is as follows: The characteristic data corresponding to the electronic file transmitted by the authorized person includes the space occupancy capacity of the electronic file, the total number of metadata items, the proportion of key content distribution, the total number of graphics, and the average resolution of the graphics.

[0011] The historical operation and maintenance data of the printer includes the average printing speed, the frequency of printing interruptions, the average response duration, and the average printing frequency of the printer in the historical printing cycle.

[0012] Based on the characteristic data corresponding to the electronic file transmitted by the authorized person, the basic characteristic value of the electronic file is processed.

[0013] According to the basic characteristic value of the electronic file, the corresponding document printing security efficiency verification value is matched.

[0014] Based on the comprehensive analysis of the historical operation and maintenance data of the printer, the performance analysis index value of the printer is obtained.

[0015] Based on the performance analysis index value of the printer and the document printing security efficiency verification value, the document printing security efficiency evaluation value of the printer is obtained.

[0016] Further, the process of performing the print pre-execution judgment is as follows: comparing the document printing security efficiency evaluation value of the printer with the set document printing security efficiency evaluation threshold to obtain a preliminary print pre-execution judgment result.

[0017] The preliminary print pre-execution judgment result includes a preliminary judgment of executable printing and a preliminary judgment of non-executable printing.

[0018] If the document printing security efficiency evaluation value of the printer is higher than or equal to the set document printing security efficiency evaluation threshold, the preliminary print pre-execution judgment result is marked as a preliminary judgment of executable printing; if the document printing security efficiency evaluation value of the printer is lower than the set document printing security efficiency evaluation threshold, the preliminary print pre-execution judgment result is marked as a preliminary judgment of non-executable printing.

[0019] Further, the process of obtaining the print pre-execution judgment result is as follows: the print pre-execution judgment result includes executable printing and non-executable printing.

[0020] The number of sheets of the electronic document transmitted by the authorized person is added to the set number of sheets to obtain the threshold of the number of sheets for this print.

[0021] Extract the preliminary print pre-execution judgment result. If the preliminary print pre-execution judgment result is marked as a preliminary judgment of executable printing, extract the paper margin of the printer and compare it with the threshold of the number of sheets for this print. If the paper margin of the printer is higher than or equal to the threshold of the number of sheets for this print, mark the print pre-execution judgment result as executable printing, and remind the authorized person that the transmitted electronic document can be printed immediately. If the paper margin of the printer is lower than the threshold of the number of sheets for this print, remind the staff to increase the paper margin of the printer, and compare the paper margin of the printer with the threshold of the number of sheets for this print again during the preset supervision time period. If the paper margin of the printer is higher than or equal to the threshold of the number of sheets for this print during the preset supervision time period, mark the print pre-execution judgment result as executable printing; if the paper margin of the printer is lower than the threshold of the number of sheets for this print during the preset supervision time period, mark the print pre-execution judgment result as non-executable printing.

[0022] Further, the process of retrieving the running data of each current idle printer is as follows: extract the print pre-execution determination result. If the print pre-execution determination result is marked as not executing printing, then extract the running data of each idle printer, where the running data of each idle printer includes the average printing speed, the printing interruption frequency, and the average data transmission speed of each idle printer during the historical printing cycle in the preset supervision cycle.

[0023] Based on the running data of each idle printer and in combination with the document printing security efficiency verification value, comprehensively analyze to obtain the print execution evaluation value of each idle printer.

[0024] Further, the process of screening and adapting the printer to execute the electronic file printing process of the authorized personnel is as follows: compare the print execution evaluation values of each idle printer, traverse and screen to obtain the idle printer with the largest print execution evaluation value, mark this idle printer as the adapted printer and execute the electronic file printing process of the authorized personnel.

[0025] Further, the performance analysis index value of the printer, the specific analysis conditions are: ; where represents the performance analysis index value of the printer, represents the average printing speed of the printer, represents the compensation factor corresponding to the set unit average printing speed, represents the printing interruption frequency of the printer, represents the compensation factor corresponding to the set unit printing interruption frequency, represents the average response duration of the printer, represents the compensation factor corresponding to the set unit average response duration, represents the average printing frequency of the printer, represents the compensation factor corresponding to the set unit average printing frequency.

[0026] Further, a document printing security management system further includes: A print log security control module, which is used to count the print log records of all printers in the preset control cycle, and perform security control processing on several remaining electronic files. The specific process is as follows: based on several remaining electronic files, collect the basic parameters of each remaining electronic file, and then match to obtain the execution compression ratio of each remaining electronic file, and transmit each remaining electronic file to the cloud platform according to the execution compression ratio of each remaining electronic file.

[0027] The second aspect of the present invention provides a document printing security management method, including: performing print permission authentication on the requesting printing personnel, and after successful authentication, recording the requesting printing personnel as authorized personnel.

[0028] Collect the characteristic data corresponding to the electronic files transmitted by authorized personnel, and synchronously retrieve the historical operation and maintenance data of the printer for comprehensive processing to obtain the document printing security performance evaluation value of the printer. Then, perform a pre-print execution judgment based on this to obtain a pre-print execution judgment result, where the pre-print execution judgment result is to execute printing or not to execute printing.

[0029] Analyze based on the pre-print execution judgment result. If the pre-print execution judgment result is to execute printing, remind the authorized personnel that the transmitted electronic file can be printed immediately. If the pre-print execution judgment result is not to execute printing, retrieve the operation data of each current idle printer for collection, and screen and match the printer to execute the printing process of the authorized personnel's electronic files.

[0030] The third aspect of the present invention provides a document printing security management storage medium, on which a computer program is stored, further including: when the computer program is executed by a processor, the above-mentioned document printing security management system is implemented.

[0031] The present invention has the following beneficial effects: (1) The present invention provides a document printing security management system. First, it performs permission authentication, effectively preventing unauthorized printing. Then, it analyzes the characteristic data corresponding to the electronic files, which can analyze the importance of the electronic files. At the same time, it retrieves the historical operation and maintenance data of the printer for comprehensive processing, which can improve the accuracy of printer matching. Finally, it analyzes based on the pre-print execution judgment result, improving the printing efficiency and accuracy.

[0032] (2) By analyzing the basic characteristic values of the electronic files, the present invention can more accurately evaluate the importance and priority of the files, which helps to reasonably allocate printing resources, ensure that key files are given corresponding printing processing, and thus improve the efficiency of the overall printing process. By identifying the basic characteristics of the electronic files, additional security measures can be implemented for sensitive or important files, enhancing the data protection level of the electronic files, and thus obtaining a more reliable and satisfactory printing service experience.

[0033] (3) By analyzing the pre-print execution judgment result, the present invention helps to more accurately match the most suitable printer, ensuring the smooth completion of the printing task. At the same time, by comprehensively evaluating the document printing security performance of the printer, the situation of sending sensitive files to printers with lower security can be reduced, thereby improving the security of the overall printing environment. The automated pre-print execution judgment process makes the printing process more intelligent, thus reducing the possibility of human errors.

[0034] (4) The present invention performs the printing process of the electronic files of authorized personnel through parallel screening and adaptation to the printer, ensuring the best match between the electronic files and the printer, thereby improving the accuracy of printing matching, helping to reduce printing delays and reprinting situations caused by printer mismatches, improving the overall printing efficiency, and optimizing the allocation and use of printer resources.

[0035] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figure 1 As shown, a technical solution is provided in the first aspect of the embodiment of the present invention: A document printing security management system includes a printing permission authentication module for performing printing permission authentication on the personnel requesting printing, and recording the personnel requesting printing as authorized personnel after successful authentication.

[0041] A pre-print execution judgment module for collecting the characteristic data corresponding to the electronic files transmitted by the authorized personnel, and synchronously retrieving the historical operation and maintenance data of the printer for comprehensive processing to obtain the document printing security efficiency evaluation value of the printer, thereby performing a pre-print execution judgment to obtain a pre-print execution judgment result, and the pre-print execution judgment result is to execute printing or not to execute printing.

[0042] A printing control processing module for analyzing based on the pre-print execution judgment result. If the pre-print execution judgment result is to execute printing, it reminds that the electronic files transmitted by the authorized personnel can be printed immediately. If the pre-print execution judgment result is not to execute printing, it retrieves the operation data of each current idle printer for collection, and screens and adapts the printer to perform the printing process of the electronic files of the authorized personnel.

[0043] Specifically, the historical operation and maintenance data of the printer is retrieved synchronously and comprehensively processed to obtain the evaluation value of the document printing security efficiency of the printer. The specific process is as follows: The characteristic data corresponding to the electronic document transmitted by the authorized personnel includes the space occupancy capacity of the electronic document, the total number of metadata items, the proportion of the distribution of key content, the total number of graphics, and the average resolution of the graphics.

[0044] It should be added that the space occupancy capacity of the electronic document refers to the storage space occupied by the electronic document in the storage medium. The file size can be obtained using programming languages (such as Python, C++). The total number of metadata items of the electronic document refers to the number of all metadata items contained in the electronic document. Metadata is descriptive information about the electronic document, and the metadata of image files can be read using ExifTool in Python. The proportion of the distribution of key content of the electronic document refers to the proportion of different types of content (such as text, images, videos, etc.) in the electronic document. The proportion of the distribution of key content of the electronic document can be obtained by processing the content of the file with Python and analyzing the sizes of different parts. The total number of graphics of the electronic document refers to the number of all graphic objects contained in the electronic document. The average resolution of the graphics of the electronic document refers to the average value of the resolutions of all images in the electronic document. The total number of graphics and the average resolution of the graphics of the electronic document can be identified using image processing libraries (such as PIL, OpenCV).

[0045] The historical operation and maintenance data of the printer includes the average printing speed, the frequency of printing interruptions, the average response time, and the average printing frequency of the printer in the historical printing cycle.

[0046] It should be added that the average printing speed of the printer usually refers to the speed at which the printer prints a document in the normal working mode. The total time and the total number of printed pages of the printing process are recorded in the log file, and the ratio of the total number of printed pages to the total time is used as the average printing speed of the printer. The frequency of printing interruptions of the printer refers to the number of times the printer pauses printing due to failures, paper shortages, paper jams, ink shortages, or other reasons during the printing process. The frequency of printing interruptions of the printer can be obtained from the log file. The average response time of the printer refers to the time interval from sending the printing command to the printer starting to print. The duration between each printing command sent and the start of printing can be captured using monitoring software, and the average value is taken to obtain the average response time of the printer. The average printing frequency of the printer refers to the number of printing tasks executed by the printer per unit time. The average printing frequency of the printer can be obtained from the log file.

[0047] Based on the characteristic data corresponding to the electronic document transmitted by the authorized personnel, the basic characteristic value of the electronic document is processed.

[0048] In this embodiment, the basic feature value of an electronic document represents the numerical quantization result of the quality evaluation value of the electronic document obtained by analyzing the corresponding feature data of the electronic document, and is used to comprehensively quantify the importance of the electronic document. It can be obtained through the following analysis method, and the specific analysis conditions are as follows: ; In the formula, represents the basic feature value of the electronic document, represents the space occupancy capacity of the electronic document, represents the correction factor corresponding to the set unit space occupancy capacity, represents the total number of metadata items of the electronic document, represents the correction factor corresponding to the set unit total number of metadata items, represents the proportion of the distribution of key content of the electronic document, represents the correction factor corresponding to the set unit proportion of the distribution of key content, represents the total number of graphics of the electronic document, represents the correction factor corresponding to the set unit total number of graphics, represents the average resolution of the graphics of the electronic document, represents the correction factor corresponding to the set unit average resolution of the graphics, and e represents the natural constant.

[0049] It should be added that in this embodiment, the correction factor corresponding to the set unit space occupancy capacity, the correction factor corresponding to the set unit total number of metadata items, the correction factor corresponding to the set unit proportion of the distribution of key content, the correction factor corresponding to the set unit total number of graphics, and the correction factor corresponding to the set unit average resolution of the graphics are obtained from the document printing management database.

[0050] It should be explained that the correction factor corresponding to the unit space occupancy capacity represents the numerical value of the influence degree of the space occupancy capacity of the electronic file on the basic eigenvalue. The correction factor corresponding to the total number of unit metadata items represents the numerical value of the influence degree of the total number of metadata items of the electronic file on the basic eigenvalue. The correction factor corresponding to the proportion of the distribution of unit key content represents the numerical value of the influence degree of the proportion of the distribution of key content of the electronic file on the basic eigenvalue. The correction factor corresponding to the total number of unit graphics represents the numerical value of the influence degree of the total number of graphics of the electronic file on the basic eigenvalue. The correction factor corresponding to the average resolution of unit graphics represents the numerical value of the influence degree of the average resolution of graphics of the electronic file on the basic eigenvalue. These corresponding relationships are pre-set mapping relationships. For example, the space occupancy capacity of the electronic file and the correction factor corresponding to the preset unit space occupancy capacity obtained from the printing and copying management database form a mapping set. The real-time space occupancy capacity of the electronic file is input into the mapping set to obtain the correction factor corresponding to the unit space occupancy capacity of the electronic file. The total number of metadata items of the electronic file and the correction factor corresponding to the preset total number of unit metadata items obtained from the printing and copying management database form a mapping set. The real-time total number of metadata items of the electronic file is input into the mapping set to obtain the correction factor corresponding to the total number of unit metadata items of the electronic file. The proportion of the distribution of key content of the electronic file and the correction factor corresponding to the preset proportion of the distribution of unit key content obtained from the printing and copying management database form a mapping set. The real-time proportion of the distribution of key content of the electronic file is input into the mapping set to obtain the correction factor corresponding to the proportion of the distribution of unit key content of the electronic file. The total number of graphics of the electronic file and the correction factor corresponding to the preset total number of unit graphics obtained from the printing and copying management database form a mapping set. The real-time total number of graphics of the electronic file is input into the mapping set to obtain the correction factor corresponding to the total number of unit graphics of the electronic file. The average resolution of graphics of the electronic file and the correction factor corresponding to the preset average resolution of unit graphics obtained from the printing and copying management database form a mapping set. The real-time average resolution of graphics of the electronic file is input into the mapping set to obtain the correction factor corresponding to the average resolution of unit graphics of the electronic file.

[0051] It should be added that there is a correlation among the space occupancy capacity, the total number of metadata items, the proportion of the distribution of key content, the total number of graphics, and the average resolution of graphics of the electronic file, and they do not exist independently. For example, the total number of graphics and the graphic resolution directly affect the storage requirements of the file. Image and graphic files usually occupy a large part of the file capacity. If the electronic file contains a large number of graphics or graphics with a high resolution, the space occupancy capacity of the electronic file will also increase accordingly. If the graphics occupy most of the space of the file, it usually means that there is a positive correlation between the total number and quality of the graphics and the proportion of the key content of the file. The more the total number of graphics, the higher the proportion of the key content of the file may be.

[0052] It should be noted that by analyzing the space occupied by an electronic document, it is possible to provide basic information about the complexity and content volume of the electronic document. Analyzing the total number of metadata items of the electronic document can help understand the integrity and traceability of the document. Analyzing the proportion of the distribution of key content in the electronic document can evaluate the core part that determines the value and importance of the document, thereby improving the accuracy of evaluating the importance of the document. Analyzing the total number of graphics in the electronic document can better determine whether the document involves complex analysis or data presentation. Analyzing the average resolution of the graphics in the electronic document can accurately evaluate the actual importance of the document.

[0053] In this implementation plan, by comprehensively analyzing the space occupied by the electronic document, the total number of metadata items, the proportion of the distribution of key content, the total number of graphics, and the average resolution of the graphics, the basic characteristic value of the electronic document is obtained, and the importance of the electronic document can be evaluated.

[0054] According to the basic characteristic value of the electronic document, the corresponding document printing security efficiency verification value is obtained by matching.

[0055] It should be added that the process of obtaining the corresponding document printing security efficiency verification value is as follows: based on the mapping set between the basic characteristic value intervals of each electronic document and the document printing security efficiency verification values pre-constructed in the document printing management database, input the basic characteristic value of the electronic document, match the interval where the basic characteristic value of the electronic document is located, and obtain the document printing security efficiency verification value corresponding to the basic characteristic value of the electronic document through the mapping set, which is recorded as the document printing security efficiency verification value corresponding to the electronic document.

[0056] It should be noted that the document printing security efficiency verification value represents the numerical quantization result of the required performance of the printer corresponding to the electronic document obtained by analyzing the basic characteristic value of the electronic document. The larger the basic characteristic value of the electronic document, the more important the electronic document is, and the higher the performance of the printer required for printing the electronic document, and the higher the corresponding document printing security efficiency verification value obtained by matching.

[0057] Based on the comprehensive analysis of the historical operation and maintenance data of the printer, the performance analysis index value of the printer is obtained.

[0058] In this embodiment, the performance analysis index value of the printer represents the numerical quantization result of the performance analysis index value of the printer obtained by analyzing the historical operation and maintenance data of the printer, and is used to comprehensively quantify the performance of the printer.

[0059] Specifically, the specific analysis conditions for the performance analysis index value of the printer are as follows: ; In the formula, represents the performance analysis index value of the printer, Represents the average printing speed of the printer, Represents the compensation factor corresponding to the set unit average printing speed, Represents the printing interruption frequency of the printer, Represents the compensation factor corresponding to the set unit printing interruption frequency, Represents the average response time of the printer, Represents the compensation factor corresponding to the set unit average response time, Represents the average printing frequency of the printer, Represents the compensation factor corresponding to the set unit average printing frequency.

[0060] It should be added that the higher the average printing speed of the printer, the higher the output efficiency of the printer, and the higher the performance analysis index value of the printer. The higher the printing interruption frequency of the printer, the poorer the reliability and lower the performance of the printer. Frequent interruptions will affect the overall printing efficiency and stability, and the performance analysis index value of the printer will also be lower. The shorter the average response time of the printer, the faster the printer can respond to the user's requests, and the higher the performance analysis index value of the printer. The higher the average printing frequency of the printer, the more tasks the printer needs to process per unit time, reflecting the workload and production capacity of the printer. Under high load conditions, a higher average printing frequency usually indicates that the printer can effectively handle a large number of tasks, and the performance analysis index value of the printer is also higher.

[0061] In a specific embodiment, Table 1 shows the average printing speed, printing interruption frequency, average response time, average printing frequency of different printers and the corresponding performance analysis index values. In this embodiment, the compensation factor corresponding to the unit average printing speed is 0.3, the compensation factor corresponding to the unit printing interruption frequency is 0.2, the compensation factor corresponding to the unit average response time is 0.3, and the compensation factor corresponding to the unit average printing frequency is 0.2.

[0062] Table 1 Average printing speed, printing interruption frequency, average response time, average printing frequency of different printers and the corresponding performance analysis index values It should be noted that in Table 1, as the average printing speed and average printing frequency of the printer increase, the performance analysis index value of the printer increases. As the printing interruption frequency and average response time of the printer increase, the performance analysis index value of the printer decreases. Table 1 lists the average printing speed, printing interruption frequency, average response time, average printing frequency and the corresponding performance analysis index values of 5 different printers, providing the influence degree of the average printing speed, printing interruption frequency, average response time and average printing frequency of different printers on the performance analysis index value. The performance analysis index value comprehensively considers the average printing speed, printing interruption frequency, average response time and average printing frequency of the printer, providing data support for the matching of the printing machine for electronic files.

[0063] It should be added that in this embodiment, the compensation factors corresponding to the preset unit average printing speed, the compensation factor corresponding to the unit printing interruption frequency, the compensation factor corresponding to the unit average response time and the compensation factor corresponding to the unit average printing frequency are obtained from the document printing management database.

[0064] It should be explained that the compensation factor corresponding to the unit average printing speed represents the numerical value of the influence degree of the average printing speed of the printer in the historical printing cycle on the performance analysis index value. The compensation factor corresponding to the unit printing interruption frequency represents the numerical value of the influence degree of the printing interruption frequency of the printer in the historical printing cycle on the performance analysis index value. The compensation factor corresponding to the unit average response duration represents the numerical value of the influence degree of the average response duration of the printer in the historical printing cycle on the performance analysis index value. The compensation factor corresponding to the unit average printing frequency represents the numerical value of the influence degree of the average printing frequency of the printer in the historical printing cycle on the performance analysis index value. These corresponding relationships are pre-set mapping relationships. For example, the average printing speed of the printer in the historical printing cycle and the compensation factor corresponding to the preset unit average printing speed obtained from the document printing management database form a mapping set. Input the average printing speed of the printer in the real-time historical printing cycle into the mapping set to obtain the compensation factor corresponding to the unit average printing speed of the printer in the historical printing cycle. The printing interruption frequency of the printer in the historical printing cycle and the compensation factor corresponding to the preset unit printing interruption frequency obtained from the document printing management database form a mapping set. Input the printing interruption frequency of the printer in the real-time historical printing cycle into the mapping set to obtain the compensation factor corresponding to the unit printing interruption frequency of the printer in the historical printing cycle. The average response duration of the printer in the historical printing cycle and the compensation factor corresponding to the preset unit average response duration obtained from the document printing management database form a mapping set. Input the average response duration of the printer in the real-time historical printing cycle into the mapping set to obtain the compensation factor corresponding to the unit average response duration of the printer in the historical printing cycle. The average printing frequency of the printer in the historical printing cycle and the compensation factor corresponding to the preset unit average printing frequency obtained from the document printing management database form a mapping set. Input the average printing frequency of the printer in the real-time historical printing cycle into the mapping set to obtain the compensation factor corresponding to the unit average printing frequency of the printer in the historical printing cycle.

[0065] It should be added that there is a correlation among the average printing speed, printing interruption frequency, average response duration, and average printing frequency of the printer in the historical printing cycle, and they do not exist independently. For example, if the average printing speed of the printer is too high, it may lead to an increase in the printing interruption frequency. The printer may experience problems such as overheating, insufficient memory, or paper jams. A high printing interruption frequency will reduce the output efficiency of the printer, resulting in a decrease in the average printing frequency. A higher average printing speed can increase the average printing frequency, directly affecting the output efficiency of the printer. It should be noted that by analyzing the average printing speed of the printer, the working efficiency of the printer under normal usage conditions can be understood. By analyzing the frequency of printing interruptions of the printer, potential stability issues during the operation of the printer can be analyzed. Analyzing the average response time of the printer helps analyze the processing efficiency of the printer after receiving instructions. Analyzing the average printing frequency of the printer can better analyze the durability of the printer and its ability to adapt to high-frequency work.

[0066] In this implementation, by comprehensively analyzing the average printing speed, printing interruption frequency, average response time, and average printing frequency of the printer in the historical printing cycle, the performance analysis index value of the printer can be obtained to evaluate the performance of the printer in actual use and analyze the stability and reliability of the printer.

[0067] Based on the performance analysis index value of the printer and the document printing security efficacy verification value, the document printing security efficacy evaluation value of the printer is obtained.

[0068] In this embodiment, the ratio of the performance analysis index value of the printer to the document printing security efficacy verification value is used as the document printing security efficacy evaluation value of the printer. The document printing security efficacy evaluation value of the printer represents the quantified result obtained by analyzing the document printing security efficacy verification value and the performance analysis index value of the printer, and is used to comprehensively quantify the printing efficacy of the printer.

[0069] Specifically, a pre-print execution judgment is performed. The specific process is as follows: The document printing security efficacy evaluation value of the printer is compared with the set document printing security efficacy evaluation threshold to obtain a preliminary pre-print execution judgment result.

[0070] The preliminary pre-print execution judgment result includes a preliminary judgment of executable printing and a preliminary judgment of non-executable printing.

[0071] If the document printing security efficacy evaluation value of the printer is higher than or equal to the set document printing security efficacy evaluation threshold, the preliminary pre-print execution judgment result is marked as a preliminary judgment of executable printing. If the document printing security efficacy evaluation value of the printer is lower than the set document printing security efficacy evaluation threshold, the preliminary pre-print execution judgment result is marked as a preliminary judgment of non-executable printing.

[0072] It should be added that if the preliminary pre-print execution judgment result is marked as a preliminary judgment of non-executable printing, the pre-print execution judgment result is not to execute printing.

[0073] Specifically, the pre-print execution judgment result is obtained. The specific process is as follows: The pre-print execution judgment result includes executing printing and not executing printing.

[0074] Add the number of sheets of the electronic file transmitted by the authorized personnel to the set number of sheets to obtain the paper threshold for this printing.

[0075] Extract the preliminary determination result of pre-execution printing. If the preliminary determination result of pre-execution printing is marked as execute printing, then extract the remaining paper amount of the printer and compare it with the paper threshold for this printing. If the remaining paper amount of the printer is higher than or equal to the paper threshold for this printing, then mark the determination result of pre-execution printing as execute printing, reminding that the electronic file transmitted by the authorized personnel can be printed immediately. If the remaining paper amount of the printer is lower than the paper threshold for this printing, then remind the staff to increase the remaining paper amount of the printer, and compare the remaining paper amount of the printer with the paper threshold for this printing again during the preset supervision time period. If the remaining paper amount of the printer is higher than or equal to the paper threshold for this printing during the preset supervision time period, then mark the determination result of pre-execution printing as execute printing. If the remaining paper amount of the printer is lower than the paper threshold for this printing during the preset supervision time period, then mark the determination result of pre-execution printing as not execute printing.

[0076] Specifically, call the current idle printers for operation data collection. The specific process is as follows: extract the determination result of pre-execution printing. If the determination result of pre-execution printing is marked as not execute printing, then extract the operation data of each idle printer, where the operation data of each idle printer includes the average printing speed, printing interruption frequency of each idle printer in the historical printing cycle, and the average data transmission speed of each idle printer in the preset supervision cycle.

[0077] It should be added that the average data transmission speed of each idle printer in the preset supervision cycle refers to the speed when transmitting information between the idle printer and the data source, and the average data transmission speed of each idle printer can be measured using network traffic monitoring tools (such as Wireshark, NetFlow, ntopng, etc.).

[0078] Based on the operation data of each idle printer and combined with the document printing security efficiency verification value, comprehensively analyze to obtain the printing execution evaluation value of each idle printer.

[0079] In this embodiment, the printing execution evaluation value of each idle printer represents the numerical quantization result of the printing execution evaluation value obtained by analyzing the operation data of each idle printer, and is used to comprehensively quantify whether the printer is suitable for executing the printing task. It can be obtained through the following analysis method. The specific analysis conditions are as follows: ; In the formula, represents the printing execution evaluation value of the i-th idle printer, represents the average printing speed of the i-th idle printer in the historical printing cycle, Represents the weight factor corresponding to the set unit average printing speed. Represents the printing interruption frequency of the i-th idle printer in the historical printing cycle. Represents the weight factor corresponding to the set unit printing interruption frequency. Represents the average data transfer speed of the i-th idle printer in the preset supervision cycle. Represents the weight factor corresponding to the set unit average data transfer speed. Represents the verification value of the document printing security efficiency. i represents the number of each idle printer. , n represents the total number of idle printers, and e represents the natural constant.

[0080] It should be explained that Figure 2 is an example graph of the change of the printing execution evaluation value of the idle printer with the average printing speed. As Figure 2 shown, where the horizontal axis represents the average printing speed of the idle printer, and the vertical axis represents the printing execution evaluation value of the idle printer. In this embodiment, the weight factor corresponding to the unit average printing speed is 0.4, the weight factor corresponding to the unit printing interruption frequency is 0.2, the weight factor corresponding to the unit average data transfer speed is 0.2, the verification value of the document printing security efficiency is 10, the printing interruption frequency of the idle printer is 3 times. Three groups of different example parameters are defined in the figure, corresponding to different situations of the three curves, represented by solid line, dashed line and dotted line respectively, and the corresponding curve labels are a, b, c.

[0081] It should be explained that when the average data transfer speed of the idle printer is 10 Mbps, the function relationship image between the average printing speed and the printing execution evaluation value of the idle printer is as shown by curve a. When the average data transfer speed of the idle printer is 15 Mbps, the function relationship image between the average printing speed and the printing execution evaluation value of the idle printer is as shown by curve b. When the average data transfer speed of the idle printer is 20 Mbps, the function relationship image between the average printing speed and the printing execution evaluation value of the idle printer is as shown by curve c. The printing execution evaluation value of the idle printer increases with the increase of the average printing speed. When the average data transfer speed of the idle printer increases, the printing execution evaluation value of the idle printer increases accordingly. Through the curve, the printing execution evaluation value of the idle printer can be obtained quickly and accurately, solving the problem that in the prior art, the printing execution evaluation value of the idle printer cannot be accurately analyzed due to the lack of detailed analysis process, and thus realizing the accurate matching of the printer.

[0082] It should be added that in this embodiment, the weight factor corresponding to the preset unit average printing speed, the weight factor corresponding to the unit printing interruption frequency, and the weight factor corresponding to the unit average data transfer speed are obtained from the document printing management database.

[0083] It should be explained that the weight factor corresponding to the unit average printing speed represents the value of the influence degree of the average printing speed of each idle printer in the historical printing cycle on the printing execution evaluation value. The weight factor corresponding to the unit printing interruption frequency represents the value of the influence degree of the printing interruption frequency of each idle printer in the historical printing cycle on the printing execution evaluation value. The weight factor corresponding to the unit average data transmission speed represents the value of the influence degree of the average data transmission speed of each idle printer in the preset supervision cycle on the printing execution evaluation value. These corresponding relationships are preset mapping relationships. For example, the average printing speed of each idle printer in the historical printing cycle and the weight factor corresponding to the preset unit average printing speed obtained from the document printing management database form a mapping set. Input the average printing speed of each idle printer in the real-time historical printing cycle into the mapping set to obtain the weight factor corresponding to the unit average printing speed of each idle printer in the historical printing cycle. The printing interruption frequency of each idle printer in the historical printing cycle and the weight factor corresponding to the preset unit printing interruption frequency obtained from the document printing management database form a mapping set. Input the printing interruption frequency of each idle printer in the real-time historical printing cycle into the mapping set to obtain the weight factor corresponding to the unit printing interruption frequency of each idle printer in the historical printing cycle. The average data transmission speed of each idle printer in the preset supervision cycle and the weight factor corresponding to the preset unit average data transmission speed obtained from the document printing management database form a mapping set. Input the average data transmission speed of each idle printer in the real-time preset supervision cycle into the mapping set to obtain the weight factor corresponding to the unit average data transmission speed of each idle printer in the preset supervision cycle.

[0084] It should be noted that by analyzing the average printing speed of each idle printer in the historical printing cycle, the accuracy of the performance evaluation of idle printers can be improved. By analyzing the printing interruption frequency of each idle printer in the historical printing cycle, the factors that may affect the smooth completion of printing tasks can be identified. By analyzing the average data transmission speed of each idle printer in the preset supervision cycle, the data interaction efficiency between the printer and the network can be evaluated.

[0085] In this implementation plan, through comprehensive analysis of the average printing speed, printing interruption frequency of each idle printer in the historical printing cycle, the average data transmission speed of each idle printer in the preset supervision cycle, and the document printing security efficiency verification value, the printing execution evaluation value of each idle printer can be obtained, which can evaluate the efficiency and security of printing device management, timely discover idle printers with qualified performance, and then perform printing.

[0086] Specifically, the screening and adaptation printer performs the printing process of the electronic files of authorized personnel. The specific process is as follows: compare the printing execution evaluation values of each idle printer, traverse and screen to obtain the idle printer with the largest printing execution evaluation value, mark this idle printer as the adapted printer, and perform the printing process of the electronic files of authorized personnel.

[0087] Specifically, a document printing security management system further includes: A printing log security control module, which is used to count the printing log records of all printers in a preset control period, and count a number of remaining electronic files for security control processing. The specific process is as follows: based on a number of remaining electronic files, collect the basic parameters of each remaining electronic file, and then match to obtain the execution compression ratio of each remaining electronic file, transfer each remaining electronic file to the cloud platform according to the execution compression ratio of each remaining electronic file, and at the same time delete the local remaining electronic files.

[0088] It should be added that the basic parameters of each remaining electronic file include the space occupancy capacity, redundancy, access frequency, and total number of graphics of each remaining electronic file. Analyze the basic parameters of each remaining electronic file to obtain the storage optimization evaluation value of each remaining electronic file.

[0089] It should be noted that the redundancy of each remaining electronic file refers to the repeated or redundant information in the electronic file, and the access frequency of each remaining electronic file refers to the number of times the file is accessed or requested within a specific time range. The redundancy and access frequency of each remaining electronic file can be obtained through the system log.

[0090] In this embodiment, the storage optimization evaluation value of each remaining electronic file represents the numerical quantization result of the storage optimization evaluation value obtained by analyzing the basic parameters of each remaining electronic file, and is used to comprehensively quantify the storage optimization requirements of each remaining electronic file. It can be obtained through the following analysis method. The specific analysis conditions are as follows: ; In the formula, represents the storage optimization evaluation value of the jth remaining electronic file, represents the space occupancy capacity of the jth remaining electronic file, represents the weight factor corresponding to the set unit space occupancy capacity, represents the redundancy of the jth remaining electronic file, represents the weight factor corresponding to the set unit redundancy, represents the access frequency of the jth remaining electronic file, represents the weight factor corresponding to the set unit access frequency, represents the total number of graphics of the jth remaining electronic file, Indicates the weight factor corresponding to the total number of preset unit graphics, j represents the number of each remaining electronic file, , m represents the total number of remaining electronic files, and e represents the natural constant.

[0091] It should be added that there is a correlation among the space occupancy capacity, redundancy, access frequency, and total number of graphics of each remaining electronic file, and they do not exist independently. For example, electronic files with higher redundancy usually occupy more storage space. Since each remaining electronic file may be stored in multiple copies, although the redundancy of the remaining electronic files improves the security and reliability of the data, it also means that the same electronic file consumes more storage resources, and the space occupancy capacity of the electronic file is also higher. Electronic files with high access frequency may require higher redundancy to ensure that there is no service interruption or delay during frequent access. Electronic files with a larger space occupancy capacity may contain more data, images, or content, and the total number of graphics is also more.

[0092] It should be added that in this embodiment, the weight factor corresponding to the preset unit space occupancy capacity, the weight factor corresponding to the unit redundancy, the weight factor corresponding to the unit access frequency, and the weight factor corresponding to the unit total number of graphics are obtained from the document printing management database.

[0093] It should be explained that the weight factor corresponding to the unit space occupancy capacity represents the numerical value of the influence degree of the space occupancy capacity of each remaining electronic file on the storage optimization evaluation value. The weight factor corresponding to the unit redundancy represents the numerical value of the influence degree of the redundancy of each remaining electronic file on the storage optimization evaluation value. The weight factor corresponding to the unit access frequency represents the numerical value of the influence degree of the access frequency of each remaining electronic file on the storage optimization evaluation value. The weight factor corresponding to the unit total number of graphics represents the numerical value of the influence degree of the total number of graphics of each remaining electronic file on the storage optimization evaluation value. These corresponding relationships are pre-set mapping relationships. For example, the space occupancy capacity of each remaining electronic file and the weight factor corresponding to the pre-set unit space occupancy capacity obtained from the document printing management database form a mapping set. Input the real-time space occupancy capacity of each remaining electronic file into the mapping set to obtain the weight factor corresponding to the unit space occupancy capacity of each remaining electronic file. The redundancy of each remaining electronic file and the weight factor corresponding to the pre-set unit redundancy obtained from the document printing management database form a mapping set. Input the real-time redundancy of each remaining electronic file into the mapping set to obtain the weight factor corresponding to the unit redundancy of each remaining electronic file. The access frequency of each remaining electronic file and the weight factor corresponding to the pre-set unit access frequency obtained from the document printing management database form a mapping set. Input the real-time access frequency of each remaining electronic file into the mapping set to obtain the weight factor corresponding to the unit access frequency of each remaining electronic file. The total number of graphics of each remaining electronic file and the weight factor corresponding to the pre-set unit total number of graphics obtained from the document printing management database form a mapping set. Input the real-time total number of graphics of each remaining electronic file into the mapping set to obtain the weight factor corresponding to the unit total number of graphics of each remaining electronic file.

[0094] In this implementation plan, a comprehensive analysis is carried out on the space occupancy capacity, redundancy, access frequency, and total number of graphics of each remaining electronic file to obtain the storage optimization evaluation value of each remaining electronic file, which can evaluate the importance of each remaining electronic file, and then optimize the storage method of each remaining electronic file.

[0095] It should be noted that the execution compression ratio of each remaining electronic file is matched according to the storage optimization evaluation value of each remaining electronic file. The specific process is as follows: Based on the mapping set between the storage optimization evaluation value interval and the execution compression ratio of each remaining electronic file pre-constructed in the document printing management database, input the storage optimization evaluation value of each remaining electronic file to match the interval where the storage optimization evaluation value of each remaining electronic file is located, and obtain the execution compression ratio corresponding to the storage optimization evaluation value of each remaining electronic file through the mapping set, which is recorded as the execution compression ratio of each remaining electronic file.

[0096] It should be noted that a document printing security management system further includes a document printing management database, which is used to store the correction factors corresponding to the occupied capacity per unit space, the correction factors corresponding to the total number of unit metadata items, the correction factors corresponding to the distribution ratio of unit key content, the correction factors corresponding to the total number of unit graphics, the correction factors corresponding to the average resolution of unit graphics, the compensation factors corresponding to the average printing speed per unit, the compensation factors corresponding to the printing interruption frequency per unit, the compensation factors corresponding to the average response time per unit, the compensation factors corresponding to the average printing frequency per unit, the document printing security performance evaluation threshold, the number of sheets of paper, the weight factors corresponding to the average printing speed per unit, the weight factors corresponding to the printing interruption frequency per unit, the weight factors corresponding to the average data transmission speed per unit, the weight factors corresponding to the occupied capacity per unit space, the weight factors corresponding to the redundancy per unit, the weight factors corresponding to the access frequency per unit, and the weight factors corresponding to the total number of unit graphics obtained by analyzing historical data.

[0099] Based on the analysis of the pre-execution judgment result of printing, if the pre-execution judgment result of printing is to execute printing, it is reminded that the electronic file transmitted by the authorized person can be printed immediately. If the pre-execution judgment result of printing is not to execute printing, the operation data of each current idle printer is retrieved for collection, and the adapted printer is screened to execute the printing process of the electronic file of the authorized person.
