[0026] Example 1

[0027] like Figure 1 As shown, this disclosure proposes a secure office method using a mobile storage device, implemented through a secure office apparatus for the mobile storage device. The apparatus includes a fuse monitoring module and comprises the following steps:

[0028] S100: Obtain the file directory status of the first office software, wherein the file directory status includes the file creation status and the file click status;

[0029] Specifically, the FUSE monitoring module is mainly used to monitor changes to a file or folder, and can add custom information about what other processes write to or read from this folder or file. Since the underlying driver for FUSE is provided by the Linux kernel, FUSE internally handles the scheduling between the driver layer and the application layer. Leveraging FUSE's data interception capabilities, file creation and opening can be achieved using FUSE only at the application layer, eliminating the need for additional driver devices, thus reducing driver development costs and minimizing the need for interactive user interface development.

[0030] The FUSE monitoring module monitors the file directory status of the primary office software in real time. The primary office software refers to any office software on the office device connected to the mobile storage device. The file directory status of the primary office software refers to the file directory stored on the office device corresponding to the primary office software, such as the desktop directory of the office device. When a file corresponding to the primary office software is created or opened, the FUSE monitoring module can detect it. Therefore, the file directory status includes the file creation status and the file click status. For example, the file creation status is when a new file is created on the desktop directory of the office device, and the file click status is when a file is clicked on the desktop directory of the office device.

[0031] Preferably, the fuse monitoring module, as a client plugin, can run in the background as a startup item for a long time, monitoring the status of the office equipment's file directory in real time, and providing indication information for file storage or file opening on mobile storage devices.

[0032] Because the fuse monitoring module internally handles the scheduling between the driver layer and the application layer, mobile storage devices no longer need to be compatible with the drivers of office equipment, nor do they need to rely on specific USB flash drives to meet office needs, thus improving the practicality of the scenario. Furthermore, it reduces driver development costs and the need for interactive user interface development, thereby reducing office risks.

[0033] S200: When the file directory status is the file creation status, receive the Create message;

[0034] Specifically, the Create message refers to one of several callback functions implemented internally by fuse that intercept file behavior. This message callback is generated when a file is created. The Create message can determine the basic information such as the name and path of the file to be created, providing an information basis for the subsequent creation of a file with the same name in the removable storage device.

[0035] S300: Based on the Create message, create a first file with the same name in the removable storage device;

[0036] Furthermore, such as Figure 2 As shown, step S300, which involves creating a first file with the same name in the removable storage device according to the Create message, includes the following steps:

[0037] S310: The Create message includes create callback parameters;

[0038] S320: Retrieve the file name and file path to be created based on the create callback parameters;

[0039] S330: Based on the file name and the file path, create a first file with the same name, a first file handle with the same name, and a soft link to the first file with the same name in the mobile storage device;

[0040] S340: Update the mount directory of the mobile storage device by using a symbolic link to the first file with the same name;

[0041] S350: Send the handle of the first file with the same name to the first office software.

[0042] Specifically, the first file with the same name refers to a file with the exact same name as one created on the office device. By creating this first file with the same name on the removable storage device, it becomes easier to open the first file with the same name on the removable storage device when clicking on a file shortcut created on the office device, thus reducing the storage pressure on the office device. The preferred method for creating this file is as follows:

[0043] The `create` callback parameter stores basic information related to the created file, including at least the filename and file path. When the `fuse` monitoring module receives the filename and file path, it creates a first file with the same name, a handle to that file, and a symbolic link to that file on the removable storage device. Users can then directly edit this first file on the removable storage device, such as adding, deleting, or modifying it. The handle to the first file is the unique identifier for opening it. The symbolic link to the first file is a link to it; it contains the path to another file, which can be any file or directory, and can link to files on different file systems. The symbolic link points to the first file with the same name, and the removable storage device's mount directory is updated, recording the set of files stored on the device. Preferably, the removable storage device's mount directory is grouped by file type, and directories with the same file type are further grouped according to office software for easy retrieval later. Preferably, a symbolic link with the same name is created in the mount directory of the removable storage device, pointing to the redirected file. This ensures the accuracy of file redirection by using the latest redirection information.

[0044] The handle of the first file with the same name is returned to the first office software, which will be used as the identification basis when opening the first file with the same name in the subsequent step. When the user needs to open the first file with the same name, the symbolic link of the first file with the same name is determined through the handle of the first file with the same name, and then the first file with the same name is opened.

[0045] When office software reads / writes file content, since file handles, first-name soft links, etc. are files on removable storage devices, the edited data is stored on the removable storage device, which improves the editability of files on the removable storage device and enhances the user experience.

[0046] S400: When the file directory status is the clicked file status, receive the open message;

[0047] Specifically, the open message refers to one of several callback functions implemented internally by fuse to intercept file behavior. This message callback is generated when a file is opened. The open message can determine basic information such as the name of the file to be opened, the file handle, and the symbolic link, providing an information basis for opening the file with the same name on the removable storage device in the subsequent step.

[0048] S500: Based on the open message, open the second file with the same name in the removable storage device.

[0049] Furthermore, the step S500 of opening the second file with the same name in the removable storage device according to the open message includes the following steps:

[0050] S510: Obtain the soft link of the clicked file based on the open message;

[0051] S520: Traverse the mount directory of the mobile storage device and determine whether the clicked file soft link points to a second file soft link with the same name;

[0052] S530: If the target is specified, open the second file with the same name in the mobile storage device and return the handle of the second file with the same name to the first office software.

[0053] Specifically, the clicked file handle can be determined through the open message, and then the clicked file symbolic link can be obtained based on the clicked file handle. Then, based on the mount directory of the removable storage device, it is determined whether the clicked file symbolic link belongs to the file content stored in the removable storage device. Here, the second symbolic link with the same name refers to the file symbolic link corresponding to any mount directory of the removable storage device. The second symbolic link with the same name refers to the file with the same name stored in the removable storage device that corresponds to the file name opened by the user when the fuse monitoring module detects that the file name opened by the user belongs to the mount directory of the removable storage device.

[0054] If the file symbolic link points to a second file with the same name, the second file with the same name in the removable storage device will be opened automatically based on the second file with the same name, and the handle of the second file with the same name will be returned to the first office software for file recognition.

[0055] Furthermore, the step S500, which involves opening a second file with the same name within the removable storage device based on the open message, further includes the following steps:

[0056] S540: If the clicked file soft link does not point to the second file soft link with the same name, obtain the clicked file name and the clicked file path;

[0057] S550: Based on the clicked file name and the clicked file path, create a third file with the same name, a handle to the third file with the same name, and a soft link to the third file with the same name in the mobile storage device;

[0058] S560: Update the mount directory of the removable storage device by using the symbolic link of the third file with the same name to point to the third file with the same name;

[0059] S570: Send the handle of the third file with the same name to the first office software.

[0060] Specifically, if the clicked file symbolic link does not point to a second symbolic link with the same name, the clicked file name and path are obtained. Based on the clicked file name and path, a third file with the same name, a handle to the third file with the same name, and a symbolic link to the third file with the same name are created in the removable storage device. The symbolic link to the third file with the same name is used to point to the third file with the same name. The mount directory of the removable storage device is updated, and the handle to the third file with the same name is sent to the first office software. Here, the third file with the same name refers to a file with the same name stored on the removable storage device when the fuse monitoring module detects that the file name opened by the user does not belong to the mount directory of the removable storage device. The storage method is exactly the same as the storage method of the first file with the same name, and the third file with the same name can be opened in real time.

[0061] In summary, the secure office method and apparatus for mobile storage devices provided in this disclosure have at least the following technical effects:

[0062] 1. The FUSE monitoring module monitors the office status of the computer in real time, specifically the file directory status of each office software application. When a user creates a file using the first office software, the file directory status is "File Creation Status." When a user opens a file using the first office software, the file directory status is "File Click Status." When the file directory status is "File Creation Status," a "Create" message is received. Based on the "Create" message, a first file with the same name is created on the removable storage device. When the file directory status is "File Click Status," an "Open" message is received. Based on the "Open" message, a second file with the same name is opened on the removable storage device. Since file creation and opening are both performed within the disk and do not require multiple file transfers, this achieves the technical effect of reducing the risk of file leakage and improving the user experience.

[0063] 2. Because the fuse monitoring module internally handles the scheduling between the driver layer and the application layer, mobile storage devices no longer need to be compatible with the drivers of office equipment, nor do they need to rely on specific USB flash drives to meet office needs, thus improving the practicality of the application. Furthermore, it reduces driver development costs and the need for interactive user interface development, thereby mitigating office risks.

[0064] 3. By mounting directories on removable storage devices, a one-to-one correspondence is established between files stored on the device and their symbolic links, ensuring that previously created symbolic links stored on the local disk can correctly point to files on the disk.

[0065] Example 2

[0066] like Figure 3 As shown, based on the same inventive concept as the aforementioned secure office method for mobile storage devices, this disclosure also provides a secure office device for mobile storage devices, including a fuse monitoring module, the fuse monitoring module comprising:

[0067] The directory status monitoring unit 11 is used to obtain the file directory status of the first office software, wherein the file directory status includes the file creation status and the file click status;

[0068] The first message receiving unit 12 is used to receive a Create message when the file directory status is the file creation status;

[0069] Create message processing unit 13 is used to create a first file with the same name in the mobile storage device according to the Create message;

[0070] The second message receiving unit 14 is used to receive an open message when the file directory status is the clicked file status;

[0071] The open message processing unit 15 is configured to open a second file with the same name in the removable storage device according to the open message.

[0072] Furthermore, the Create message processing unit 13 performs the following steps:

[0073] The Create message includes create callback parameters;

[0074] Based on the create callback parameters, retrieve the file name and file path to be created;

[0075] Based on the file name and the file path, create a first file with the same name, a handle to the first file with the same name, and a soft link to the first file with the same name in the mobile storage device.

[0076] The mount directory of the mobile storage device is updated by using a symbolic link to the first file with the same name.

[0077] Send the handle of the first file with the same name to the first office software.

[0078] Furthermore, the open message processing unit 15 performs the following steps:

[0079] Based on the open message, obtain the soft link of the clicked file;

[0080] Traverse the mounted directory of the mobile storage device and determine whether the clicked file soft link points to a second file soft link with the same name;

[0081] If the target is specified, open the second file with the same name in the mobile storage device and return the handle of the second file with the same name to the first office software.

[0082] Furthermore, the open message processing unit 15 further includes the following steps:

[0083] If the clicked file soft link does not point to the second file soft link with the same name, obtain the clicked file name and the clicked file path;

[0084] Based on the clicked file name and the clicked file path, create a third file with the same name, a handle to the third file with the same name, and a soft link to the third file with the same name in the mobile storage device;

[0085] The mount directory of the removable storage device is updated by using a symbolic link to the third file with the same name.

[0086] Send the handle of the third file with the same name to the first office software.
