[0042] Please refer to Figure 1 and Figure 2 , the embodiments of the present invention provide a method for secure approval of classified documents, and the method includes the following steps:

[0043] S1, collect the files to be processed by the printer, and the files to be processed include at least one of printed files, copied files, and scanned files.

[0044] In specific implementation, the files to be processed by the printer are monitored in real time. The files to be processed include at least one of printed files, copied files, and scanned files. A printed file refers to a file to be printed, a copied file refers to a file to be copied, and a scanned file refers to a file to be scanned.

[0045] When a new file to be processed is detected in the printer, before the printer processes the file to be processed, collect the file to be processed.

[0046] In some embodiments, such as this embodiment, after collecting the file to be processed by the printer, the method further includes: converting the file to be processed into a preset target format to obtain a target file.

[0047] In specific implementation, the preset target format may be the JPG picture format, and the file to be processed can be converted into the preset target format through a preset format conversion component to obtain a target file. Converting to a unified format facilitates the accuracy of subsequent processing.

[0048] For example, converting the file to be processed into the JPG picture format, the JGP picture format has good compatibility and stability, and can maintain a consistent display effect on different devices and operating systems. At the same time, using OCR technology can convert the text in the JPG picture into an editable text format, which is convenient for subsequent file editing, retrieval, and sharing.

[0049] S2. Determine whether the file to be processed contains confidential information.

[0050] In specific implementation, obtain the text information contained in the file to be processed, and determine whether the text information contains preset confidential information.

[0051] For example, in some embodiments, such as this embodiment, the above step "determine whether the file to be processed contains confidential information" specifically includes the following steps:

[0052] S21. Identify the text information contained in the target file.

[0053] In specific implementation, after the file to be processed is converted into a preset target format to obtain a target file, the text information contained in the target file is identified through a preset OCR recognition component. OCR refers to optical character recognition technology, which is used to accurately identify the text information contained in the target file.

[0054] S22. Based on the preset confidential data, determine whether the text information contains confidential information.

[0055] In specific implementation, the confidential data may be a preset confidential text library and confidential keywords. Determine whether the text information contains the content in the confidential text library and whether it contains confidential keywords. If so, determine that the text information contains confidential information; if not, determine that the text information does not contain confidential information.

[0056] S23. If the text information contains confidential information, determine that the file to be processed contains confidential information.

[0057] S24. If the text information does not contain classified information, it is determined that the file to be processed does not contain classified information.

[0058] S3. If the file to be processed contains classified information, determine the approver corresponding to the file to be processed, and send an approval process to the approver.

[0059] In specific implementation, if the file to be processed contains classified information, determine the approver corresponding to the file to be processed, and send an approval process to the approver. The approver can be one or more. Functions such as multi-level approval, emergency approval, and approval record query are supported. The approver can view the details of the file to be processed, approval history, and approval opinions in the approval process, and make a decision on whether to allow further processing.

[0060] The approval process can specifically notify the corresponding approver for review by means of emails, text messages, instant messaging information, etc., and the present invention does not specifically limit this.

[0061] If the file to be processed does not contain classified information, there is no need to initiate a classified approval, and the printer can directly output the file to be processed.

[0062] In some embodiments, such as this embodiment, the above step of "determining the approver corresponding to the classified file" specifically includes the following steps:

[0063] S31. Based on the classified information contained in the file to be processed, determine the classified level of the file to be processed.

[0064] In specific implementation, multiple classified levels can be set, and the present invention does not specifically limit this. A first preset relationship between classified information and classified levels is preset in advance, and the classified level corresponding to the classified information contained in the file to be processed is determined according to the first preset relationship.

[0065] If the file to be processed contains one piece of classified information, use the classified level corresponding to the classified information as the classified level of the file to be processed.

[0066] If the file to be processed contains multiple pieces of classified information, determine the classified levels of the multiple pieces of classified information respectively, and use the highest classified level among the classified levels of the multiple pieces of classified information as the classified level of the file to be processed.

[0067] S32. Determine the approver of the file to be processed according to the classified level.

[0068] In specific implementation, a second preset relationship between the secrecy level and the approver is preset in advance, and the approver corresponding to the secrecy level is determined according to the second preset relationship as the approver of the to-be-processed document. Based on the secrecy level, the approver can be one or more. If there are multiple approvers, a multi-level approval method, a parallel approval method, or a combination of multi-level approval and parallel approval can be adopted.

[0069] In some embodiments, such as this embodiment, after the above step of "sending an approval process to the approver", the method further includes the following steps: If a query request for the approval progress of the to-be-processed document sent by the terminal is received, obtain the approval progress of the to-be-processed document, and return the approval progress of the to-be-processed document to the terminal.

[0070] In specific implementation, the user can query the approval progress of the to-be-processed document. Specifically, the user sends a query request for the approval progress of the to-be-processed document to the server through a terminal (such as a mobile phone, a computer, etc.). After the server receives the query request for the approval progress of the to-be-processed document sent by the terminal, it obtains the approval progress of the to-be-processed document and returns the approval progress of the to-be-processed document to the terminal, thereby realizing real-time query of the approval progress. At the same time, the user can also send a reminder request for the approval process to the server through the terminal to notify the approver to review as soon as possible.

[0071] S4. Obtain the approval result of the approval process, and determine the processing method of the to-be-processed document based on the approval result.

[0072] In specific implementation, after the approver finishes the approval, obtain the approval result of the approval process, and determine the processing method of the to-be-processed document based on the approval result. Specifically:

[0073] If the approval result is approval passed, control the printer to output the to-be-processed document. That is, when the to-be-processed document is a print document, control the printer to print the to-be-processed document; when the to-be-processed document is a copy document, control the printer to copy the to-be-processed document; when the to-be-processed document is a scan document, control the printer to scan the to-be-processed document.

[0074] If the approval result is approval not passed, control the printer to reject processing the to-be-processed document, and at the same time send a secrecy warning message to remind the user that the to-be-processed document is secret and printing, copying, and scanning are prohibited.

[0075] An embodiment of the present invention provides a method for secure approval of confidential documents, including: collecting the documents to be processed by the printer, where the documents to be processed include at least one of printed documents, copied documents, and scanned documents; determining whether the documents to be processed contain confidential information; if the documents to be processed contain confidential information, determining the approver corresponding to the documents to be processed, and sending an approval process to the approver; obtaining the approval result of the approval process, and determining the processing method of the documents to be processed based on the approval result. Before the printer prints, copies, and scans documents, the present invention pre-determines whether the documents to be processed contain confidential information. If so, it automatically initiates an approval process and determines the processing method of the documents to be processed based on the approval result, thereby greatly improving the security of confidential documents, effectively avoiding the leakage of confidential documents, and having the advantages of high efficiency, high accuracy, and low cost compared with the manual control method.

[0076] The method for secure approval of confidential documents of the present invention is applied to an automatic approval system, which consists of the following several subsystems: a document collection and conversion system, an OCR recognition and confidential detection system, an approval process management system, and a user operation and feedback system. Among them:

[0077] Document collection and conversion system: This system is responsible for receiving or automatically scanning the documents to be processed by the printer and converting them into a unified format (such as JPG image format).

[0078] OCR recognition and confidential detection system: This system uses advanced OCR (Optical Character Recognition) technology to automatically identify and extract the text information in the document. Subsequently, the recognized text is matched with a pre-set confidential text library or keywords to detect whether the document contains sensitive or confidential content.

[0079] Approval process management system: Once a confidential document is detected, this system will automatically trigger the approval process. According to the level of the confidential content and the pre-set rules, this system will notify the corresponding approver to review by email or text message in the first time. The approver can view the document details, approval history, and approval opinions through this system and make a decision on whether to allow further processing. The system also supports functions such as multi-level approval, emergency approval, and approval record query.

[0080] User operation and feedback system: This system provides a friendly operation interface and a real-time feedback mechanism for end users. Users can submit documents, query the approval progress, and receive approval result notifications through this system.

[0081] The technical solution of the present invention has the following technical effects:

[0082] Improve the accuracy of classified document management: By converting the documents to be processed by the printer into JGP picture format and using the OCR recognition component to recognize the text information in them, this solution can achieve precise capture and analysis of the document content, ensure accurate recognition of classified content, avoid possible oversights in traditional manual reviews, and thus improve the accuracy of classified document management.

[0083] Enhance the automation and efficiency of classified document approval: By matching the preset classified text or keywords with the recognized text information, this solution can automatically determine whether a document is classified and send the document to the corresponding approver for approval according to the classification level. This automated approval process not only greatly improves the approval efficiency but also reduces human intervention and the security risks in the approval process. At the same time, the text corresponding to each classification level has different levels of approvers, ensuring the rigor and accuracy of the approval.

[0084] Guarantee the security of classified documents: Through a strict approval process, effective control is carried out on the output and transmission of classified documents. Once the classified content of the document is recognized, the approval mechanism will be triggered to ensure that the document will not be output or leaked without authorization, providing a strong guarantee for the security of classified documents.

[0085] Optimize the document processing flow: Converting the document into JGP picture format and using OCR technology for text recognition can further optimize the document processing flow. The JGP picture format has good compatibility and stability, and can maintain a consistent display effect on different devices and operating systems. At the same time, OCR technology can convert the text in the image into an editable text format, facilitating subsequent document editing, retrieval, and sharing.

[0086] Complete printing and copying supervision solution: The system incorporates printing, copying, and scanning operations into the supervision and review mechanism to comprehensively ensure the security of printing and copying output.
