Description

Technical Field

[0001] This invention relates to the field of medical image printing equipment control technology, and in particular to a password-authorized printing control method and system for a medical image printer. Background Technology

[0002] With the popularization of medical imaging technology, medical image printers in hospitals are widely used to output patient image films. These films carry patients' private information and diagnostic data, which are core confidential medical data of the hospital. Currently, most hospitals adopt the direct printing mode of workstations directly connecting to printers. After medical staff submit the print job on the computer, the image data is transmitted in plaintext to the printer's cache storage. The device does not have a secondary identity verification and single print authorization mechanism.

[0003] In the aforementioned existing technologies, the traditional medical image printing process does not have a time-limited one-time authorization verification mechanism bound to a single printing task, and lacks a closed-loop security control throughout the entire process, which can easily lead to the leakage of patients' image privacy information. Summary of the Invention

[0004] The purpose of this invention is to provide a password-authorized printing control method and system for a medical image printer, aiming to solve the technical problem in the existing medical image printing process that lacks a time-limited one-time authorization verification mechanism bound to a single printing task, lacks full-process security closed-loop control, and is prone to leakage of patient image privacy information.

[0005] To achieve the above objectives, the present invention employs a password-authorized printing control method for a medical image printer, comprising the following steps: Obtain the identity of the user and the patient information of the image to be printed, encrypt the print job and send it to the printer; After the printer receives an encrypted print job, it generates a unique and time-limited one-time authorization code and notifies the user. After completing user authentication on the printer control panel, enter the obtained authorization code to initiate print confirmation; Verify the validity of the authorization code and the user's operation permissions. If the verification is successful, decrypt and print; otherwise, refuse to print and record the failure event. After printing is complete, upload the job information, patient information, operator information, and authorization code usage record to the hospital information management system; The current authorization code will be immediately invalidated, the printing quota of the medical staff will be deducted in real time, and the temporary key will be automatically cleared and the operation panel will be locked after the device has been idle for a preset time.

[0006] Among the steps, the following steps are involved: obtaining the user's identity and the patient's information regarding the images to be printed, encrypting the print job, and then sending it to the printer: Collect the complete set of identity information of medical staff when they initiate a print request at the front-end workstation. The identity information includes the corresponding employee number, name, department and account permissions. Retrieve the original medical image files corresponding to this printing task, and simultaneously extract the patient's name, medical record number, examination items, and basic diagnostic information; Integrate operator identity data, patient privacy information, and medical image files, and encapsulate them into standardized, interlocked print job data packages; The complete encrypted print job data packet is pushed to the local encrypted cache queue of the medical image printer via a dedicated transmission channel on the hospital's intranet for temporary storage.

[0007] Among the steps, after the printer receives the encrypted print job, it generates a unique and time-limited one-time authorization code and notifies the user: Receive encrypted print job data packets transmitted over the intranet, store the data packets in a local, independent encrypted partition on the device, and create a unique task identifier to bind to this print job; Generate a one-time authorization code that corresponds uniquely to the current print job identifier and is globally unique; Configure the validity period of the authorization code, set a fixed time threshold, and the authorization code will automatically expire after the time limit is exceeded and will no longer support printing verification. The authorization code will be sent to the operator.

[0008] In the step of completing user authentication on the printer control panel and entering the obtained authorization code to initiate print confirmation: Wake up the medical image printer's control panel and enter the dedicated operation interface for print verification; Submit the operator's identity certificate to complete the identity verification on the panel. The identity certificate includes card swiping, facial recognition, account password and employee number entry. Single or multiple combinations of methods can be used for verification. Enter the authorization code input interface and manually enter the one-time authorization code for this print job that was previously pushed out. After confirming that the authorization code is entered correctly, submit the print confirmation command and send a film printing execution request to the printer.

[0009] The process of verifying the validity of the authorization code and the user's operating permissions, decrypting and printing if the verification is successful, and rejecting printing and recording the failure event if the verification fails: Retrieve the original authorization code data from the device cache and verify whether the input authorization code matches, is within the validity period, or is marked as used; Check the current operator's background permission file to verify whether the medical staff member has the permission to print the current type of medical imaging film; After matching all verification conditions, the temporary decryption key specific to the print job is retrieved, the encrypted data packet is decrypted, and the printing hardware is driven to output the image film. Capture any scenario where verification fails, directly block the printing process, collect and save failure records, including operation time, operator, device number, and reason for failure.

[0010] Among the steps, after printing is completed, the job information, patient information, operator information, and authorization code usage record are uploaded to the hospital information management system: Monitor the operating status of the printing equipment and wait for the film to be completely output and the entire printing process to be completed; Summarize all the basic data for this task, including print job number, image type, patient medical record, and operator identity. Organize the usage records, including the usage time, usage status, and validity period of the authorization code; All aggregated data is packaged and transmitted in real time to the hospital information management system for log archiving and storage.

[0011] Among the steps, the following steps are involved: immediately invalidating the current authorization code, deducting the medical staff's printing quota in real time, and automatically clearing the temporary key and locking the operation panel after the device has been idle for a preset time: Mark the authorization code that has been printed as permanently invalid, and prohibit the repeated use of the authorization code to perform printing; Match the operator with the corresponding printing quota account and deduct the available printing quota in real time according to the single printing standard; The system tracks and records the idle time of the equipment, continuously monitoring the idle status of the panel when there is no operation or printing task. Once the idle time reaches a preset threshold, the temporary decryption key used for this print job is cleared, and the printer control panel is locked to restrict external operations.

[0012] This invention also provides a password-authorized printing control system for a medical image printer, comprising a print job encryption distribution module, a one-time authorization code generation module, an identity verification module, a permission and authorization code verification module, a log upload and archiving module, and a post-security control module; wherein: The print job encryption and distribution module is used to obtain the identity of the user and the patient information of the image to be printed, and then encrypt the print job before sending it to the printer. The one-time authorization code generation module is used to receive and cache encrypted print jobs, generate a unique and time-limited one-time authorization code, and notify the user. The identity verification module is used to complete multi-method identity verification for operators. After successful verification, it supports the input of a one-time authorization code and sends a print confirmation instruction to the printer. The permission and authorization code verification module is used to verify the validity of the authorization code and the user's operation permissions. If the verification is successful, the code is decrypted and printed; if it fails, printing is refused and the failure event is recorded. The log upload and archiving module is used to monitor the completion status of printing tasks, summarize all data related to printing jobs, patients, operators and authorization codes, package them and upload them to the hospital information management system in real time to complete log archiving and retention. The post-installed security control module is used to immediately mark the authorization code as permanently invalid after printing, deduct the corresponding medical staff's printing quota in real time, continuously monitor the idle time of the device, and automatically clear the temporary decryption key and lock the printer operation panel after the idle time reaches the preset time.

[0013] This invention discloses a password-authorized printing control method and system for a medical image printer. The method comprises a print job encryption and distribution module, a one-time authorization code generation module, an identity verification module, a permission and authorization code verification module, a log upload and archiving module, and a post-security management module. The steps include: obtaining the user's identity and patient information for the images to be printed; encrypting the print job and sending it to the printer; generating a unique and time-limited one-time authorization code and informing the user after receiving the encrypted print job; completing user identity verification on the printer's control panel and entering the obtained authorization code to initiate print confirmation; verifying the validity of the authorization code and the user's operating permissions; decrypting and printing if successful, and rejecting printing and recording the failure event if unsuccessful; uploading the job information, patient information, operator information, and authorization code usage record to the hospital information management system after printing is completed; immediately invalidating the current authorization code, deducting the medical staff's printing quota in real time, and automatically clearing the temporary key and locking the control panel after the device has been idle for a preset time; through these methods, the system effectively prevents the leakage of patient image privacy, ensures full traceability of the operation, and provides automated security management.

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0026] It should be understood that although the terms first, second, third, etc., may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0027] Please see Figures 1-7This invention provides a password-authorized printing control method for a medical image printer, comprising the following steps: S100: Obtains the identity of the user and the patient information of the image to be printed, encrypts the print job, and sends it to the printer.

[0028] In this embodiment, the user's identity and the patient's information regarding the image to be printed are obtained, the print job is encrypted, and then sent to the printer. The specific process is as follows: 101: Collect the complete set of identity information of medical staff when they initiate a print request at the front-end workstation. The identity information includes the corresponding employee number, name, department and account permissions. S102: Retrieve the original medical image file corresponding to this printing task, and simultaneously extract the patient's name, medical record number, examination items and basic diagnostic information; S103: Integrate operator identity data, patient privacy information, and medical image files, and encapsulate them into a standardized, mutually bound data package for printing jobs; S104: Encrypt the complete print job data packet and push the data packet to the local encrypted cache queue of the medical image printer for temporary storage through the hospital's intranet dedicated transmission channel.

[0029] During the above process, the complete identity information of medical staff when initiating a print request at the front-end workstation is collected. This identity information includes the corresponding employee number, name, department, and account permissions. Then, the original medical image files corresponding to this print job are retrieved, and the patient's name, medical record number, examination items, and basic diagnostic information are extracted simultaneously. The operator's identity data, patient privacy information, and medical image files are then integrated and packaged into a standardized print job data package that is bound to each other. The complete print job data package is encrypted and pushed to the local encrypted cache queue of the medical image printer for temporary storage via a dedicated transmission channel on the hospital's intranet. Throughout the entire process, data is transmitted only through the hospital's isolated intranet, isolating external network access paths to prevent the leakage of patient privacy and image data during transmission.

[0030] S200: After the printer receives an encrypted print job, it generates a unique and time-limited one-time authorization code and notifies the user.

[0031] In this embodiment, after the printer receives an encrypted print job, it generates a unique and time-limited one-time authorization code and notifies the user. The specific process is as follows: S201: Receives encrypted print job data packets transmitted over the intranet, stores the data packets in the device's local independent encrypted partition, and creates a unique task identifier to bind to this print job; S202: Generate a one-time authorization code that corresponds uniquely to the current print job identifier and is globally unique; S203: Configure the valid usage time of the authorization code, set a fixed time threshold, and the authorization code will automatically expire after the time limit is exceeded and will no longer support printing verification. S204: Push the authorization code to the operator.

[0032] In the above process, the encrypted print job data packet transmitted over the intranet is received, stored in a local independent encrypted partition on the device, and a unique task identifier is created and bound to this print job. Then, a one-time authorization code is generated that corresponds one-to-one with the current print job identifier and is globally unique, ensuring that a print job matches only a single authorization code. The validity period of the authorization code is then configured, and a fixed time threshold is set. The authorization code automatically expires after the time limit and is no longer supported for print verification. Subsequently, the authorization code is pushed to the operator, and notification can be sent through one or more channels, such as the printer panel pop-up window, the task information page, or the internal communication system. In the above, the authorization code is only supported for single use. It will be permanently invalidated if it expires or is used up. There is no long-term universal print authorization certificate.

[0033] S300: After completing user authentication on the printer's control panel, enter the obtained authorization code to initiate print confirmation.

[0034] In this embodiment, after completing user authentication on the printer's control panel, the obtained authorization code is entered to initiate print confirmation. The specific process is as follows: S301: Wake up the medical image printer control panel and enter the dedicated operation interface for print verification; S302: Submit the operator's identity certificate to complete the identity verification on the panel. The identity certificate includes card swiping, facial recognition, account password and employee number entry. Single or multiple combinations of methods can be used for verification. S303: Enter the authorization code input interface and manually enter the one-time authorization code for this print job that was pushed earlier; S304: After confirming that the authorization code input is correct, submit the print confirmation command and send a film printing execution request to the printer.

[0035] During the above process, the medical imaging printer's control panel is activated, and the dedicated printing verification interface is accessed. The operator submits their identification credentials to complete panel-side identity verification, which can be done via card swiping, facial recognition, account password, or employee ID entry, using either a single method or a combination thereof. Then, the authorization code input interface is accessed, where the operator manually enters the previously sent one-time authorization code specific to this print job. After confirming the authorization code is correct, a print confirmation command is submitted, sending a film printing execution request to the printer. Throughout this process, personnel whose identity verification fails are prevented from accessing the authorization code input page, thus blocking unauthorized personnel from operating the equipment.

[0036] S400: Verifies the validity of the authorization code and the user's operation permissions. If the verification is successful, it decrypts and prints the code; otherwise, it refuses to print the code and records the failure event.

[0037] In this implementation, the validity of the authorization code and the user's operating permissions are verified. If the verification is successful, the code is decrypted and printed; otherwise, printing is rejected and the failure event is recorded. The specific process is as follows: S401: Retrieve the original authorization code data in the device cache and verify whether the input authorization code matches, is within the validity period, or is marked as used; S402: Query the current operator's background permission file to verify whether the medical staff has the permission to print the current type of medical imaging film; S403: After matching all verification conditions, retrieve the temporary decryption key specific to the print job, decrypt the encrypted data packet, and drive the printing hardware to output the image film. S404: Capture any scenario where verification fails, directly block the printing process, collect information and save the failure record, which includes the operation time, operator, device number and failure reason.

[0038] In the above process, the original authorization code data in the device cache is retrieved to verify whether the input authorization code matches, is within the validity period, and is marked as used; then, the current operator's background permission file is queried to verify whether the medical staff has the permission to print the current type of medical imaging film; after matching all verification conditions, the temporary decryption key specific to the print job is retrieved to decrypt the encrypted data packet and drive the printing hardware to output the imaging film; any scenario where verification fails is captured, the printing process is directly blocked, and information is collected and saved as a failure record. The information saved as a failure record includes the operation time, operator, device number, and reason for failure. In the above, the dual verification of authorization code validity and user operation permission is indispensable. All failure records are persistently stored locally and will not be automatically deleted.

[0039] S500: After printing is completed, upload the job information, patient information, operator information, and authorization code usage record to the hospital information management system.

[0040] In this embodiment, after printing is completed, the job information, patient information, operator information, and authorization code usage record are uploaded to the hospital information management system. The specific process is as follows: S501: Monitors the operating status of the printing equipment and waits for the film to be completely output and the entire printing process to be completed; S502: Summarize all the basic data of this task, including the print job number, image type, patient medical record and operator identity; S503: Organize the usage records of the authorization code, including usage time, usage status, and validity period; S504: Package all aggregated data and transmit it in real time to the hospital information management system to complete log archiving and storage.

[0041] During the above process, the operating status of the printing equipment is monitored, and the printing process is completed after the film is fully output. Then, all the basic data of this task are summarized, including the printing job number, image type, patient medical record, and operator identity. The usage records of the authorization code, including usage time, usage status, and validity period, are also compiled. All the summarized data is then packaged and transmitted in real time to the hospital information management system for log archiving and storage. The above data upload forms a complete and traceable ledger, which can quickly locate the operator and the details of the event in case of film loss or data anomalies.

[0042] S600: Immediately invalidates the current authorization code, deducts the medical staff's printing quota in real time, and automatically clears the temporary key and locks the operation panel after the device has been idle for a preset time.

[0043] In this embodiment, the current authorization code is immediately invalidated, the printing quota of the medical staff is deducted in real time, and the temporary key is automatically cleared and the operation panel is locked after the device has been idle for a preset time. The specific process is as follows: S601: Mark the authorization code that has been printed as permanently invalid, and prohibit the repeated use of the authorization code to perform printing; S602: Match the operator's corresponding printing quota account and deduct the available printing quota in real time according to the single printing standard; S603: Timers and monitors the idle time of the device, continuously monitoring the idle state of the panel when there is no operation or printing task; S604: After determining that the idle time has reached the preset threshold, clear the temporary decryption key used for this print job and lock the printer control panel to restrict external operations.

[0044] During the above process, the authorization code that has been printed is marked as permanently invalid, and repeated use of the authorization code to perform printing is prohibited; then, the corresponding printing quota account of the operator is matched, and the available printing quota is deducted in real time according to the single printing standard; then, the idle time of the device is timed and counted, and the idle state of the panel with no operation and no printing tasks is continuously monitored; after the idle time is determined to reach a preset threshold, the temporary decryption key used for this printing is cleared, and the printer operation panel is locked to restrict external operation. In the above, the authorization code invalidation, quota deduction and idle security protection are executed simultaneously, improving the overall security control level from the three dimensions of authorization, consumables and equipment.

[0045] Please see Figure 8This invention provides a password-authorized printing control system for a medical image printer, comprising a print job encryption distribution module 701, a one-time authorization code generation module 702, an identity verification module 703, a permission and authorization code verification module 704, a log upload and archiving module 705, and a post-security management module 706; wherein: The print job encryption and distribution module 701 is used to obtain the identity of the operating user and the patient information of the image to be printed, encrypt the print job and send it to the printer. The one-time authorization code generation module 702 is used to receive and cache encrypted print jobs, generate a unique and time-limited one-time authorization code, and notify the user. The identity verification module 703 is used to complete multi-method identity verification for operators. After the verification is successful, it supports the input of a one-time authorization code and sends a print confirmation instruction to the printer. The permission and authorization code verification module 704 is used to verify the validity of the authorization code and the user's operation permissions. If the verification is successful, the code is decrypted and printed; if it fails, printing is refused and the failure event is recorded. The log upload and archiving module 705 is used to monitor the completion status of printing tasks, summarize all data related to printing jobs, patients, operators and authorization codes, package them and upload them to the hospital information management system in real time to complete log archiving and retention. The post-security management module 706 is used to immediately mark the authorization code as permanently invalid after printing, deduct the printing quota of the corresponding medical staff in real time, continuously monitor the idle time of the device, and automatically clear the temporary decryption key and lock the printer operation panel after the idle time reaches the preset time.

[0046] In this embodiment, the print job encryption and distribution module 701 obtains the operator's identity and the patient's information for the image to be printed, encrypts the print job, and sends it to the printer. The one-time authorization code generation module 702 receives and caches the encrypted print job, generates a unique and time-limited one-time authorization code, and informs the operator. The identity verification module 703 performs multi-method identity verification for the operator. After successful verification, the operator can enter the one-time authorization code and sends a print confirmation command to the printer. The permission and authorization code verification module 704 verifies the validity of the authorization code and the user's operating permissions. If the verification is successful, the code is decrypted and printed; if it fails, printing is rejected and a failure event is recorded. The log upload and archiving module 705 monitors the completion status of the print job, summarizes the print job, patient, operator, and authorization code. All data related to the authorization code is packaged and uploaded to the hospital information management system in real time for log archiving. The post-installed security control module 706 immediately marks the authorization code as permanently invalid after printing, deducts the corresponding medical staff's printing quota in real time, continuously monitors the idle time of the equipment, and automatically clears the temporary decryption key and locks the printer operation panel after the idle time reaches a preset time. In the above manner, each module relies on the hospital intranet to realize data interaction and collaborative work, and sequentially completes the entire process of encrypted distribution of printing jobs, generation and push of one-time authorization codes, on-site identity verification, dual permission verification, unified log archiving, and post-printing security protection. A complete printing security closed loop is constructed through a single time-limited authorization verification mechanism to prevent the leakage of patient image privacy from the source, while realizing full traceability of printing behavior and automatic security control of equipment.

[0047] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

[0048] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.

The one-time authorization code generation module is used to receive and cache encrypted print jobs, generate a unique and time-limited one-time authorization code, and notify the user. The identity verification module is used to complete multi-method identity verification for operators. After successful verification, it supports the input of a one-time authorization code and sends a print confirmation command to the printer. The permission and authorization code verification module is used to verify the validity of the authorization code and the user's operation permissions. If the verification is successful, the code is decrypted and printed; if it fails, printing is refused and the failure event is recorded. The log upload and archiving module is used to monitor the completion status of printing tasks, summarize all data related to printing jobs, patients, operators and authorization codes, package them and upload them to the hospital information management system in real time to complete log archiving and retention. The post-installed security control module is used to immediately mark the authorization code as permanently invalid after printing, deduct the corresponding medical staff's printing quota in real time, continuously monitor the idle time of the device, and automatically clear the temporary decryption key and lock the printer operation panel after the idle time reaches the preset time.
