[0025] Figure 6 This is a schematic diagram of the structure of a computer device provided in an embodiment of the present invention. Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0027] Figure 1 This is a flowchart illustrating a file processing method provided by an embodiment of the present invention. This embodiment is applicable to scenarios involving remote file processing, particularly the deletion of files from lost devices. The method can be executed by a file processing device, which can be implemented in software and / or hardware and integrated into a computer device with application development capabilities.

[0028] like Figure 1 As shown, the file processing method in this embodiment includes the following steps:

[0029] S110. In response to the server's file hiding instruction, hide the disk file directory on the client's terminal device.

[0030] The server can be used for remote management of terminal devices. The server can establish a communication connection with terminal devices equipped with file processing devices, and send file hiding commands to these devices based on user actions or automated file processing triggers.

[0031] The file hiding instruction is used to instruct the disk file directory on the terminal device where the client is located to be hidden, so that the operator who opens the terminal device cannot see the disk files, thus protecting file security.

[0032] It's understandable that file hiding doesn't directly delete the corresponding files. Hiding disk file directories can be understood as a pre-deletion operation, allowing for further deletion or file restoration later.

[0033] The process of hiding the disk file directory on the terminal device where the client is located can be achieved by deleting or encoding / encrypting the disk file directory so that it cannot be recognized and displayed by the terminal device.

[0034] S120. In response to a file recovery command, display the disk file directory; wherein, the process of displaying the disk file directory is the reverse of the process of hiding the disk file directory.

[0035] File recovery commands can be used to reveal and restore hidden disk file directories, so that terminal devices can recognize and display the corresponding disk file directories.

[0036] Once the file is confirmed to be secure, the hidden information can be restored and displayed, making file management more flexible and meeting diverse file management needs.

[0037] The process of displaying a disk file directory is the reverse of the process of hiding it. In other words, the process and method of displaying a disk file directory depend on the process and method of hiding it. For example, if hiding a disk file directory involves deleting it, then displaying it could involve adding the deleted content. Similarly, if hiding a disk file directory involves encoding or encrypting it, then displaying it could involve decrypting the encrypted content.

[0038] The technical solution of this embodiment hides the disk file directory on the client's terminal device in response to a file hiding instruction from the server; and displays the disk file directory in response to a file recovery instruction. The process of displaying the disk file directory is the reverse of the process of hiding it. This embodiment solves the problem of unrecoverable files after remote deletion, providing remote file hiding and recovery functionality. It hides the file directory according to file processing needs, thus ensuring file security; and it also allows for file recovery according to file management needs, making file processing more flexible.

[0039] In one optional implementation, before hiding the disk file directory on the client's terminal device, a first business ownership attribute of the terminal device is verified to determine whether it matches the second business ownership attribute corresponding to the server. This step ensures that the file object being processed during file handling is a file with processing permissions. The business ownership attribute information represents the identity attribute information of the terminal device and also the ownership information of the file. When the first business ownership attribute information matches the second business ownership attribute information, the verification passes. For example, if a computer device in a company is lost, files on the lost computer device can be remotely erased or pre-erased. Before processing, it can be determined whether a user of the company is remotely processing files on the company's computer device; if the verification passes, the corresponding file processing can proceed.

[0040] Figure 2 This is a flowchart illustrating another file processing method provided by an embodiment of the present invention. This embodiment belongs to the same inventive concept as the file processing methods in the above embodiments, and further describes the processing procedure for hiding disk file directories. This method can be executed by a file processing device, which can be implemented in software and / or hardware and integrated into a computer device with application development capabilities.

[0041] like Figure 2 As shown, the file processing method in this embodiment includes the following steps:

[0042] S210. In response to the file hiding instruction from the server, delete or encrypt the disk identifier of the disk in the terminal device where the client is located.

[0043] Deleting or encrypting the disk identifier on the client's terminal device can hide file directories at the storage space level. After the disk identifier is deleted or encrypted, the corresponding disk space is not visible, and the corresponding disk file directories are also hidden.

[0044] In another alternative implementation, in response to the server's file hiding instructions, the disk file directory on the client's terminal device can also be deleted or encrypted. That is, the disk file directory is directly deleted or encrypted, making it invisible and preventing the terminal device operator from finding the files corresponding to it.

[0045] In another optional implementation, in response to a file hiding instruction from the server, the files corresponding to the disk file directory on the terminal device can be encrypted, and the encrypted files can be sent to the server; the encrypted files can then be deleted. This method hides files by remotely backing up and deleting the files corresponding to the disk file directory. The files backed up on the server can be retrieved from the server later, enabling the disk file directory to be displayed and restored.

[0046] S220. In response to a file recovery command, display the disk file directory; wherein, the process of displaying the disk file directory is the reverse of the process of hiding the disk file directory.

[0047] The technical solution of this embodiment, in response to a file hiding instruction from the server, deletes or encrypts the disk identifier of the disk on the client's terminal device; or deletes or encrypts the disk file directory on the client's terminal device; or encrypts the files corresponding to the disk file directory on the terminal device and sends the encrypted files to the server; deletes the encrypted files; and displays the disk file directory in response to a file recovery instruction. The process of displaying the disk file directory is the reverse of the process of hiding the disk file directory. This embodiment solves the problem of unrecoverable files after remote deletion, providing a file hiding function. It allows hiding the file directory according to file processing needs to ensure file security, and also allows file directory recovery according to file processing needs, making the file processing process more flexible.

[0048] Figure 3 This is a flowchart illustrating another file processing method provided by an embodiment of the present invention. This embodiment belongs to the same inventive concept as the file processing methods in the above embodiments, and further explains the file processing process after file hiding is removed. This method can be executed by a file processing device, which can be implemented in software and / or hardware and integrated into a computer device with application development capabilities.

[0049] like Figure 3 As shown, the file processing method in this embodiment includes the following steps:

[0050] S310, in response to the server's file hiding instruction, hides the disk file directory on the client's terminal device.

[0051] S320. The duration of the disk file directory being hidden is timed to obtain the duration of the time.

[0052] S330. When the preset file hiding time is reached, delete the file corresponding to the disk file directory.

[0053] Typically, you can also set an expiration date for file directory operations, which is the preset file hiding time, corresponding to the duration the target file is hidden. After the expiration date of the file directory hiding operation, the corresponding file in the disk file directory is deleted, that is, the file is completely erased.

[0054] S340. If the preset file hiding time has not been reached during the timeout period, the disk file directory is displayed in response to the file recovery command; wherein, the process of displaying the disk file directory is the reverse of the process of hiding the disk file directory.

[0055] The technical solution of this embodiment hides the disk file directory on the client's terminal device in response to the server's file hiding processing command; it times the duration of hiding the disk file directory; if the timed duration reaches the preset file hiding duration, it deletes the file corresponding to the disk file directory; if the timed duration does not reach the preset file hiding duration, it displays the disk file directory in response to the file recovery command; wherein, the process of displaying the disk file directory is the reverse of the process of hiding the disk file directory. The technical solution of this embodiment solves the problem that files cannot be recovered after remote deletion, and provides file hiding and recovery functions. Hiding files according to file processing needs ensures file security; file recovery can also be performed according to file processing needs. If the target file is not recovered for a long time, it can be completely deleted, avoiding the situation where the server cannot establish a communication connection with the terminal device equipped with a file processing device, thus making the file processing process more flexible.

[0056] Figure 4 This diagram illustrates a workflow for processing files on a target terminal in an example of a file processing method. Specifically, it includes the following steps:

[0057] 1. Sending file processing instructions from a remote end. The remote end can be a server with communication capabilities with the terminal device, capable of sending relevant operation instructions to the target terminal configured with a file processing device. File processing instructions can be instructions to erase, hide, or restore some or all files on the target terminal. Specifically, erasing instructions can directly delete files, hiding instructions can make files invisible, and restoring instructions can display and restore invisible files.

[0058] 2. The file processing device receives file processing instructions. The file processing device is a device pre-installed in the target terminal. The file processing device is activated upon receiving a file processing instruction.

[0059] 3. The file processing device will verify whether the terminal device where the file processing device is located belongs to the target object. The target object can be an object that has management permissions for the files to be erased.

[0060] 4. If verification passes, for a complete erase command, the corresponding file will be formatted or the disk will be formatted. For a hide command, the mounted files on the target disk will be hidden (or deleted after backup). If no restore command is received within a certain timeframe after executing the hide command, a complete erase will be performed to prevent situations where the signaling cannot send the complete erase command due to network connectivity issues. If a restore command is received, the hidden or backed-up files will be restored.

[0061] 5. Store the execution results.

[0062] Through the above steps, data recovery is completed after the user's computer is recovered. Secondly, the file mount entries on all drive letters and corresponding disks can be hidden, so that outsiders cannot see the specific file name list and therefore cannot assess the value of the device, thus avoiding costly decryption of the computer.

[0063] Figure 5 This is a schematic diagram of a file processing device provided in an embodiment of the present invention. This embodiment is applicable to scenarios of remote file processing, especially the deletion of files from lost devices. The file processing device can be implemented by software and / or hardware and integrated into a computer terminal device with application development capabilities.

[0064] like Figure 5The file processing device shown includes a file hiding processing module 410 and a file recovery processing module 420.

[0065] The file hiding processing module 410 is used to hide the disk file directory on the terminal device where the client is located in response to the file hiding processing instruction from the server; the file recovery processing module 420 is used to display the disk file directory in response to the file recovery instruction; wherein, the process of displaying the disk file directory is the reverse of the process of hiding the disk file directory.

[0066] The technical solution of this embodiment hides the disk file directory on the client's terminal device in response to a file hiding instruction from the server; and displays the disk file directory in response to a file recovery instruction. The process of displaying the disk file directory is the reverse of the process of hiding it. This embodiment solves the problem of files being unrecoverable after remote deletion, providing file hiding and recovery functions. It allows files to be hidden according to file processing needs, ensuring file security, and also enables file recovery, making file processing more flexible.

[0067] In an alternative implementation, the file hiding processing module 410 can be used to:

[0068] The disk identifier of the disk in the terminal device where the client is located is deleted or encrypted.

[0069] In an alternative implementation, the file hiding processing module 410 can be used to:

[0070] The disk file directory on the client's terminal device is deleted or encrypted.

[0071] In an alternative implementation, the file hiding processing module 410 can be used to:

[0072] The files corresponding to the disk file directory in the terminal device are encrypted, and the encrypted files are sent to the server.

[0073] Delete the encrypted file.

[0074] In an optional implementation, the file processing apparatus further includes a file deletion module, which can be used for:

[0075] Before receiving the file recovery command, the duration of the disk file directory being hidden is timed to obtain the time duration;

[0076] If the preset file hiding time is reached, delete the corresponding file in the disk file directory.

[0077] In an optional implementation, the file processing apparatus further includes an attribute verification module, which can be used for:

[0078] Before hiding the disk file directory on the terminal device where the client is located, the first service ownership attribute of the terminal device is verified to determine whether the first service ownership attribute is the same as the second service ownership attribute corresponding to the server.

[0079] The file processing apparatus provided in the embodiments of the present invention can execute the file processing method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of executing the method.
