Abstract
Description
Technical Field
[0001] This application relates to the technical field of data processing, and particularly to a method, device, and electronic device for in-vehicle infotainment (IVI) data processing. Background Art
[0002] With the rapid development of technology, the automotive industry has entered a new stage of intelligence and informatization. The electronic devices installed in vehicles are becoming more and more diverse. While providing convenient services, these devices also store a large amount of personal information and vehicle data. However, when a vehicle reaches the end-of-life condition, the stored data does not disappear but remains in the vehicle's IVI system. To protect the privacy of vehicle owners and the identification information of vehicles, it is necessary to erase the IVI data of scrapped vehicles.
[0003] The existing methods for IVI data processing are mainly physical destruction methods. The physical destruction method can ensure that data cannot be recovered by physically damaging the storage device (such as a hard disk or solid-state drive). Common physical destruction means include cutting, drilling, or degaussing, etc. Cutting and drilling means can physically damage storage devices such as hard disks, making them unable to read or write data. The degaussing means changes the magnetization direction of data through high-intensity head scanning to reach an unrecoverable state.
[0004] However, there are some problems with the existing physical destruction methods. For example, although cutting and drilling means can physically damage the storage device, they may not fully guarantee that the data cannot be recovered. The degaussing means may not be fully effective for some solid-state drives (such as solid-state drives using flash memory chips instead of magnetic media), resulting in data residue, enabling attackers to potentially recover access and restore some or all of the data through technical means, thereby obtaining sensitive information of the vehicle and the owner, leading to information security issues. Summary of the Invention
[0005] In view of this, this application provides a method, device, and electronic device for IVI data processing. By erasing the IVI data in all storage spaces except the bootloader in the Universal Flash Storage (UFS), the IVI system cannot be started normally, effectively preventing the secondary use of scrapped IVI systems and fully protecting the sensitive information of vehicles and vehicle owners.

[0013] An erasing module, configured to, when the startup mode of the in-vehicle system is the recovery mode, use the bootloader to erase all in-vehicle data in the target storage space.

For the embodiments of the present disclosure, first determine whether the startup mode of the in-vehicle system is the recovery mode, and when the startup mode of the in-vehicle system is the recovery mode, use the bootloader to erase all in-vehicle data in the target storage space. Since the operating system and all key data are erased, the in-vehicle system will not be able to start. Even if an attacker tries to restore or reinstall the in-vehicle system through technical means, they will not be able to obtain the sensitive information of the vehicle and the owner, thereby effectively preventing the secondary use of the in-vehicle system of a scrapped vehicle and reducing information security problems.

[0026] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details included in the embodiments of the present disclosure are helpful for understanding and should be regarded as merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, the description below omits the description of well-known functions and structures. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0027] The following describes the method, device and electronic device for processing in-vehicle data according to the embodiments of the present disclosure with reference to the drawings.
[0028] To effectively prevent the secondary use of scrapped car infotainment systems and fully protect the sensitive information of vehicles and vehicle owners, this embodiment provides a method for processing car infotainment system data, as Figure 1 shown. The method includes:
[0029] Step 101, receive a formatting request.
[0030] Among them, the formatting request can be used to indicate erasing all car infotainment system data in the target storage space; the target storage space can be all storage spaces in the Universal Flash Storage (UFS) except the bootloader.
[0031] For the embodiments of the present disclosure, the diagnostic service of the car infotainment system can receive the formatting request sent by the diagnostic instrument through the diagnostic interface, set a specific flag bit in the car infotainment system after receiving the formatting request to indicate that the car infotainment system is in the recycling mode. The bootloader will check the flag bit of the car infotainment system when starting up to determine whether the car infotainment system is in the recycling mode. If the car infotainment system is in the recycling mode, the bootloader will perform an erasing operation to erase the car infotainment system data in all storage spaces in the UFS except the bootloader. Through the control at the bootloader level, it can be ensured that the data is cleared before the operating system starts, avoiding the possibility of data recovery at the operating system level, and effectively preventing the secondary use of scrapped car infotainment systems. For details, refer to steps 102 and 103 of the embodiment.
[0032] Among them, the diagnostic instrument can be a device dedicated to vehicle diagnosis, which can be connected to the diagnostic interface of the vehicle (which can be an OBD-II interface or other dedicated diagnostic interfaces) and is used to read and send vehicle system data.
[0033] Step 102, configure the startup mode of the car infotainment system to the recycling mode based on the formatting request.
[0034] For the embodiments of the present disclosure, during the startup (or restart) process of the car infotainment system, it is determined whether the car infotainment system is in a special startup state, that is, the recycling mode, by receiving the formatting request. The recycling mode is usually used for specific maintenance or security operations, such as when the vehicle is recycled or needs to be reconfigured.
[0035] When the car infotainment system receives the formatting request and the formatting request contains specific information or commands, the car infotainment system can judge the current startup mode of the car infotainment system according to this information. For example, the formatting request may contain a special identifier or code (such as containing a specific flag bit), and the system determines whether the recycling mode is started by identifying the specific flag bit.
[0036] Among them, the startup mode can be the state or mode when the in-vehicle system starts up, and can include normal mode, safety mode, diagnostic mode, recovery mode, etc. Each mode can correspond to a series of operations and restrictions to ensure that the in-vehicle system can operate safely and effectively in different states.
[0037] The recovery mode can be a special startup mode, which can be used in scenarios where the vehicle is being recycled, repaired, or reconfigured. In the recovery mode, the in-vehicle system can perform a series of safety checks and data clearing operations to ensure that the vehicle does not contain any sensitive information or incorrect configurations before being put back into use. The recovery mode can restrict certain functions of the in-vehicle system to ensure that maintenance personnel or other authorized personnel can handle the vehicle safely.
[0038] Step 103: When the startup mode of the in-vehicle system is the recovery mode, use the bootloader to erase all in-vehicle data in the target storage space.
[0039] Among them, the bootloader can be the program that runs first during the startup process of the in-vehicle system, and is responsible for initializing the hardware and loading the operating system. When the bootloader starts up and detects that the flag bit is a special flag bit, the in-vehicle system will enter the recovery mode. In the recovery mode, the bootloader can perform an erase operation to erase the in-vehicle data in all spaces of the UFS storage except the bootloader.
[0040] For the embodiments of the present disclosure, it can be ensured that when the in-vehicle unit is scrapped or recycled, all sensitive and critical data on its memory is completely erased. Even if the in-vehicle system is mishandled or Figure 2 used again, without the support of data and the system, the in-vehicle system cannot be re-enabled, thus effectively preventing the secondary use of the in-vehicle unit and fully protecting the sensitive information of the vehicle and the owner.
[0041] In summary, according to a method for processing in-vehicle data of the present disclosure, a formatting request can be received. The formatting request is used to indicate erasing all in-vehicle data in the target storage space; configure the startup mode of the in-vehicle system to the recovery mode based on the formatting request; when the startup mode of the in-vehicle system is the recovery mode, use the bootloader to erase all in-vehicle data in the target storage space. For the embodiments of the present disclosure, first determine whether the startup mode of the in-vehicle system is the recovery mode. When the startup mode of the in-vehicle system is the recovery mode, use the bootloader to erase all in-vehicle data in the target storage space. Since the operating system and all key data are erased, the in-vehicle system will not be able to start up. Even if an attacker tries to recover or reinstall the in-vehicle system through technical means, they cannot obtain the sensitive information of the vehicle and the owner, thus effectively preventing the secondary use of the in-vehicle system of scrapped vehicles and reducing information security issues.
[0042] Further, as a refinement and extension of the above embodiments, in order to fully illustrate the specific implementation process of the method of this embodiment, this embodiment provides a specific method as shown in Figure 2 The following steps are included in the method:
[0043] Step 201: Configure the flag bit of the in-vehicle system to a specific flag bit using a formatting request, and determine that the startup mode of the in-vehicle system is the recovery mode.
[0044] Among them, the flag bit can be the status or flag in the vehicle diagnostic system, and can be used to indicate that the vehicle is ready to enter a special mode for certain types of maintenance, repair, or data clearing operations. The flag bit can be used to indicate that the in-vehicle system is in the recovery mode, system reset mode, software update mode, or formatted storage mode, etc.; the flag bit can be represented by a binary value. For example, when the flag bit is set to 1, it can indicate that the in-vehicle system is in the recovery mode, and when the flag bit is set to 0, it can indicate that the in-vehicle system is in the non-recovery mode (such as the normal mode).
[0045] The specific flag bit can be used to indicate that the in-vehicle system is in the recovery mode, and the specific flag bit can be represented by 1 to indicate that the in-vehicle system is in the recovery mode.
[0046] After receiving the formatting request, it further includes:
[0047] Verify whether the formatting request is legal. If the formatting request is legal, configure the flag bit of the in-vehicle system to a specific flag bit using the formatting request, and determine that the startup mode of the in-vehicle system is the recovery mode.
[0048] For the embodiments of the present disclosure, when the formatting request sent by the diagnostic instrument passes the security check of the in-vehicle system, by setting the specific flag bit of the in-vehicle system, when the flag bit of the in-vehicle system is allowed to be the specific flag bit, use the bootloader to erase the vehicle data in all storage spaces except the bootloader in the UFS storage, ensuring that all operations are executed according to the predetermined processes and conditions, thereby maintaining the consistency and stability of the system.
[0049] After configuring the flag bit of the in-vehicle system to a specific flag bit using the formatting request and determining that the startup mode of the in-vehicle system is the recovery mode, the method further includes:
[0050] Send a restart command, and the restart command is used to command the in-vehicle system to perform a restart operation.
[0051] For the embodiments of the present disclosure, the bootloader startup is the first step in the in-vehicle system startup, ensuring the correct configuration and initialization of the hardware and software. Among them, to ensure the bootloader startup, the diagnostic service can send a restart command to the in-vehicle system through the vehicle's bus system (such as the CAN bus). After receiving the restart command, the in-vehicle system verifies the restart command to ensure the validity and legality of the restart command. After the restart command verification passes, the in-vehicle system can perform a restart operation. During the restart process, the in-vehicle system can execute a series of steps, which may include powering off, initializing the hardware, loading the bootloader, and then the bootloader is responsible for loading the operating system and other software components.
[0052] Step 202, when the startup mode of the in-vehicle system is the recovery mode, use the bootloader to erase all in-vehicle data in the target storage space.
[0053] For the embodiments of the present disclosure, if the flag bit of the in-vehicle system is a specific flag bit (i.e., 1), it is determined that the startup mode of the in-vehicle system is the recovery mode. At this time, use the bootloader to erase the in-vehicle data in all storage spaces except the bootloader in the UFS storage.
[0054] As a possible implementation method, the specific erasure process can be: the bootloader can first perform a security check to ensure the legality of the erasure operation. The UFS storage is usually divided into multiple partitions, such as the system partition, data partition, cache partition, etc. The bootloader can access these partitions one by one and perform the erasure operation.
[0055] After erasing each partition, the bootloader can verify the erased partition to ensure that the data has been completely erased. After verifying that the erasure result is correct, the in-vehicle data in the UFS storage has been completely erased. At this time, since the data on which the in-vehicle system depends for operation has been erased, the in-vehicle system will not be able to start again, which can ensure that all sensitive and critical data on the memory of the in-vehicle system are completely erased when the in-vehicle system is scrapped or recycled, thus effectively preventing the secondary use of the in-vehicle system and fully protecting the sensitive information of the vehicle and the owner.
[0056] Step 203, when the startup mode of the in-vehicle system is the normal mode, start the in-vehicle system normally according to the normal mode.
[0057] For the embodiments of the present disclosure, use the formatting request to configure the flag bit of the in-vehicle system as a non-specific flag bit, and determine that the startup mode of the in-vehicle system is the normal mode. Among them, the non-specific flag bit is used to indicate that the in-vehicle system is in the normal mode; the normal mode can be a conventional state in which the in-vehicle system starts and runs normally according to the established procedures and functions.
[0058] The specific process of in-vehicle data processing is as Figure 3As shown in the figure, first, the diagnostic instrument triggers a formatting request. After the diagnostic service of the in-vehicle system receives the formatting request from the diagnostic instrument, it sets the in-vehicle recycling mode flag bit (i.e., a specific flag bit) to 1, indicating that the vehicle has entered the recycling mode. The diagnostic service triggers the restart of the cockpit domain controller (in-vehicle system (HU, Head Unit)). After the SoCbootloader starts, it determines whether the in-vehicle system is in the recycling mode based on whether the flag bit of the in-vehicle system is 1. Here, SoC is the abbreviation of System on Chip, which can be a system integrated on a single chip and usually includes a CPU, GPU, memory management, etc. Bootloader (boot loader) is the initial software that runs when the SoC starts, responsible for initializing the hardware and loading the operating system. The Bootloader will check the set flag bit to determine whether to enter the recycling mode. Once it is determined to enter the recycling mode, the bootloader will perform an erase operation to erase all storage spaces except the bootloader, and the vehicle will not be able to start the Android system normally. If it is not in the recycling mode, the in-vehicle system will be started normally.
[0059] In summary, according to a method for processing in-vehicle data of the present disclosure, a formatting request can be received, and the formatting request is used to indicate erasing all in-vehicle data in the target storage space; based on the formatting request, the startup mode of the in-vehicle system is configured as the recycling mode; when the startup mode of the in-vehicle system is the recycling mode, all in-vehicle data in the target storage space is erased by using the boot loader. For the embodiments of the present disclosure, first, it is determined whether the startup mode of the in-vehicle system is the recycling mode. When the startup mode of the in-vehicle system is the recycling mode, all in-vehicle data in the target storage space is erased by using the boot loader. Since the operating system and all key data are erased, the in-vehicle system will not be able to start. Even if an attacker tries to restore or reinstall the in-vehicle system through technical means, they cannot obtain the sensitive information of the vehicle and the owner, thus effectively preventing the secondary use of the in-vehicle system of scrapped vehicles and reducing information security problems.
