Description

Technical Field

[0001] This invention relates to the field of data erasure technology, and more specifically, to a data erasure method, system, device, and medium based on a client program. Background Technology

[0002] Large enterprises often possess a large number of client computers due to operational needs. In certain scenarios, it may be necessary to perform data erasure operations on specific client computers to meet enterprise security policy requirements.

[0003] For example, when an employee leaves and their client computer needs to be handed over to someone else, or when client computers are used for cross-departmental or team asset allocation or borrowing, based on enterprise security policies such as information and data security, the aforementioned client computers need to have their data erased before subsequent processes such as equipment transfer, operating system installation, and delivery can proceed.

[0004] Currently, the standard data erasure procedure is as follows:

[0005] 1. Users (or departments, teams, etc.) submit relevant requests, which, after going through the relevant approval process, are transferred and assigned to IT (Information Technology) personnel for execution;

[0006] 2. IT personnel retrieve the data from the target device or go to the workstation where the device is located to perform the following data erasure operations:

[0007] a. Check and verify whether the target device is authorized for data erasure through the company's device management platform;

[0008] b. Insert the USB flash drive carrying the PE system (a microsystem that can be loaded into memory) into the target device and boot the target device;

[0009] c. Control the target device to enter the PE system and perform relevant data erasure operations;

[0010] d. Check the disk information after data erasure to confirm the erasure result;

[0011] e. Register the erasure results on the enterprise's equipment management platform to complete the entire data erasure operation.

[0012] It is evident that the current data erasure process relies entirely on manual operation by professionals, which is cumbersome and time-consuming. When a large number of devices need data erasure, it requires a significant amount of manpower and time, and the standardization and completeness of the operation process cannot be well managed and monitored.

[0013] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

This method and system can automatically complete device verification, image file download, and data erasure operations through the execution of the data erasure client program. This allows any user to perform data erasure independently using the client program, making data erasure simple and easy to operate without IT personnel intervention. The entire process is automated and requires no manual intervention, significantly reducing labor costs, simplifying the operation process, and improving the standardization and completeness of the data erasure operation through programmed execution.

[0026] The data erasure scheme based on the client program of this invention can automatically complete the device verification, image file download and data erasure operations through the running of the data erasure client program. This allows any user to perform data erasure independently based on the data erasure client program, making data erasure simple and easy to operate without the need for IT personnel intervention.

[0027] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention. Attached Figure Description

[0031] Figure 3 This diagram illustrates the modules of a data erasure system based on a client program in an embodiment of the present invention.

[0032] Figure 4 A schematic diagram of the structure of an electronic device in an embodiment of the present invention is shown. Detailed Implementation

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to fully and completely convey the concept of the exemplary embodiments to those skilled in the art.

[0034] The accompanying drawings are merely illustrative of the invention and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0035] Furthermore, the processes shown in the accompanying drawings are merely illustrative and do not necessarily include all steps. For example, some steps can be broken down, some steps can be combined or partially combined, and the actual execution order may change depending on the actual situation. It should be noted that, unless otherwise specified, embodiments of the present invention and features in different embodiments can be combined with each other.

[0036] Figure 1 This illustrates the main steps of the data erasure method based on a client program in an embodiment of the present invention; see reference. Figure 1 As shown, the data erasure method based on a client program provided in this embodiment of the invention includes:

[0037] In step S110, the data erasure client program responds to being run and determines whether the local device meets the data erasure conditions.

[0038] The data erasure client program can be deployed on an automation management platform that communicates with the local device, such as an enterprise's OA (Office Automation) management platform. Deploying the data erasure client program on this platform facilitates user operation.

[0039] When the data erasure client program is run, it automatically queries the device on which it is running, i.e., whether the local device meets the data erasure conditions. If the local device meets the data erasure conditions, the subsequent data erasure process continues; if the local device does not meet the data erasure conditions, the current data erasure operation can be terminated.

[0040] Step S120: If the local device meets the data erasure conditions, the data erasure client program downloads an image file carrying the data erasure PE system on the local device.

[0041] PE stands for Windows Preinstallation Environment, which is the environment you need to enter before installing the operating system. A data erasure PE system can automatically perform data erasure operations on the local device.

[0042] Step S130: The data erasure client program guides the local device into the data erasure PE system so that the data erasure PE system can perform data erasure operations on the local device.

[0043] The data erasure client program can boot the local device to restart and enter the data erasure PE system to perform relevant data erasure operations.

[0044] Specifically, data erasure refers to performing a secure format on all disks of the local device to make the data on all disks unrecoverable and unreadable.

[0045] Therefore, the aforementioned data erasure method based on a client program can automatically complete device verification, image file download, and data erasure operations through the operation of the data erasure client program. This allows any user to perform data erasure independently based on the data erasure client program, making data erasure simple and easy to operate without the need for IT personnel intervention. The entire process of automatic program execution also requires no manual intervention, greatly reducing labor costs, simplifying the operation process, and improving the standardization and completeness of data erasure operations through programmatic execution.

[0046] In one embodiment, before the data erasure client program is run, the system further includes: an automated management platform, in response to a data erasure request, issuing the data erasure client program to the device that initiated the data erasure request if the device that initiated the data erasure request has been approved.

[0047] Users who need data erasure can obtain a data erasure client program from the automated management platform after completing the data erasure application and the prescribed approval process. The user can then run the data erasure client program, which will automatically check whether the local device meets the data erasure conditions.

[0048] The approval criteria for devices that initiate data erasure requests can be configured as needed, and this invention does not impose any restrictions on them.

[0049] In one embodiment, determining whether a local device meets the data erasure conditions includes: querying the approval information of the local device based on the device information of the local device; and determining that the local device meets the data erasure conditions by instructing the local device to pass the approval based on the approval information.

[0050] The local device is specifically a non-server computer device (such as a regular desktop or laptop) used for daily work based on a Windows operating system. The approval information of the local device is stored in the automated management platform. The data erasure client program can retrieve the approval information of the local device from the automated management platform based on the device information of the local device, check whether the local device has passed the approval, and then determine whether the local device meets the data erasure conditions.

[0051] In one embodiment, the data erasure client program downloads an image file carrying the data erasure PE system on the local device, including: the data erasure client program downloading the image file carrying the data erasure PE system on the local device via a file server.

[0052] In one embodiment, after the data erasure PE system performs a data erasure operation on the local device, the system further includes: the data erasure PE system detecting the data erasure result on the local device; the data erasure PE system submitting the data erasure result of the local device to an automated management platform that is connected to the local device, and displaying the data erasure result on the display interface of the local device.

[0053] For local devices that meet the data erasure criteria, the data erasure PE system automatically performs data erasure operations and submits the data erasure results to the automated management platform. Subsequently, the automated management platform can automatically manage the data erasure process for the local device based on the data erasure results, simplifying the operation process.

[0054] The above-described client-based data erasure method can automatically complete device verification, image file download, and data erasure operations by running the data erasure client program. This allows any user to perform data erasure independently using the data erasure client program, making data erasure simple and easy to operate without the need for IT personnel intervention. The entire process of automatic program execution also requires no manual intervention, greatly reducing labor costs, simplifying the operation process, and improving the standardization and completeness of data erasure operations through programmed execution.

[0055] In addition, the data erasure client program interfaces with the enterprise's automated management platform to automatically handle the data erasure process based on the data erasure results from the device, simplifying the operation process.

[0056] Figure 2 This illustrates the interaction flow of the data erasure method based on a client program in an embodiment of the present invention; see reference. Figure 2 As shown in a specific example, a client-side data erasure method completed through multi-party interaction includes:

[0057] S210, users (or departments, teams, etc.) who need data erasure submit data erasure requests to the OA management platform 200a, and the OA management platform 200a approves the data erasure requests;

[0058] S220, the OA management platform 200a sends the data erasure client program 200d to the local device, and the user runs the data erasure client program 200d;

[0059] S230, the data erasure client program 200d determines whether the local device meets the data erasure conditions, specifically including: S230a, querying the approval information of the local device from the backend interface 200b based on the device information of the local device; S230b, the backend interface 200b querying the approval information of the local device from the OA management platform 200a; S230c, the OA management platform 200a returning the approval information of the local device to the backend interface 200b; S230d, the backend interface 200b judging whether the local device meets the data erasure conditions based on the approval information returned by the OA management platform 200a, and returning the judgment result to the data erasure client program 200d;

[0060] If the local device meets the data erasure conditions, the data erasure client program 200d will continue the subsequent operations; if the local device does not meet the data erasure conditions, it will prompt the user and terminate the operation.

[0061] S240, the data erasure client program 200d downloads the image file of the data erasure PE system via the file server 200e;

[0062] S250, the data erasure client program 200d guides the local device to perform a system restart and enter the data erasure PE system 200c;

[0063] S260, the data erasure PE system 200c is running, automatically performing data erasure operations, and automatically detecting the erasure results on the local device after the data erasure is completed;

[0064] S270, the data erasure PE system 200c submits the test results to the backend interface 200b and displays the test results on the display interface of the local device, thus completing the data erasure operation;

[0065] S280, backend interface 200b submits the detection results to OA management platform 200a;

[0066] S290, the OA management platform 200a controls the local device to enter the corresponding subsequent process flow based on the detection results of the local device. Specifically, the OA management platform 200a determines whether the data erasure operation of the local device is successful based on the detection results. If successful, it controls the local device to enter the corresponding subsequent process flow; if it fails, it flows to the manual process for relevant review.

[0067] The aforementioned client-based data erasure method automatically completes device verification, image file download, and data erasure operations through the running of the data erasure client program. This allows any user to perform data erasure independently using the client program, making the process simple and easy to operate without IT personnel intervention. The entire automatic execution process requires no manual intervention, significantly reducing labor costs and simplifying the operation process. Furthermore, the programmed execution improves the standardization and completeness of the data erasure operation. In addition, the data erasure client program interfaces with the enterprise's automated management platform to automatically manage the data erasure process based on the device's data erasure results, further simplifying the operation process.
