[0050] In the vehicle system, user data is generally stored in the Data partition. Before the user needs to sell, exchange or donate it to others, the vehicle system needs to be reset to ensure that the data is permanently deleted and cannot be recovered. In the current conventional data formatting method, for example, in Android phones, user data is generally stored in the Data partition. The ADB (Android Debug Bridge) debugging tool is used to automatically enter the Recovery mode of the Android phone. In this mode, the Data partition is quickly formatted to reclaim the space for storing user privacy data, overwrite all free space in the Data partition, and cover the storage blocks with residual user data. However, in different systems, different data erasure standards perform different data erasure times and corresponding data content filling, and lack a thorough review of whether the data is erased, resulting in insufficient data erasure in some cases, thus posing a security risk.

[0051] In view of this, if Figure 1 As shown, an embodiment of the present invention provides a method for clearing personal information data of an intelligent network-connected vehicle, which may include but is not limited to steps S100 to S700:

[0052] Step S100, identifying and extracting personal information of the vehicle-mounted system to obtain target deletion data;

[0053] Step S200, presetting the number of repeated erasing and writing of the target deleted data;

[0054] Step S300, obtaining the first hash value of the target deleted data;

[0055] Step S400, obtaining a data erasing and writing program of the vehicle-mounted system;

[0056] Step S500, executing the data erasing program on the target deleted data according to the number of repeated erasing times;

[0057] Step S600, obtaining a second hash value of the erasure area of ​​the target deleted data;

[0058] Step S700, compare the first hash value with the second hash value. If the second hash value is the same as the first hash value, return to the step of obtaining the data erasing program of the vehicle system. If the second hash value is different from the first hash value, end the current smart connected vehicle personal information data clearing process.

[0059] Before step S100 in some embodiments, it also includes: obtaining debugging permissions; according to the debugging permissions, entering the vehicle system in debugging mode through debugging tools or debugging instructions. Entering the debugging mode of the vehicle system through specific debugging tools or debugging instructions usually requires specific permissions or passwords to ensure that only authorized users can access the underlying functions of the system. Exemplarily, before debugging the vehicle system, the first thing to do is to verify permissions. Some vehicle systems may require users to log in to the cloud using a user name and password pre-assigned in the cloud to activate debugging permissions. This ensures that only authorized users can enter the debugging mode, thereby protecting the vehicle system from the risk of unauthorized access. After successfully verifying the permissions, the debugging tool can then be called to debug the system.

[0060] In some embodiments, step S100 may include but is not limited to steps S110 to S130:

[0061] Step S110, scanning the data storage area of ​​the vehicle-mounted system, identifying and extracting personal information of the vehicle-mounted system;

[0062] Step S120, classifying the personal information to obtain several data types;

[0063] Step S130: acquiring the target deletion data according to the data type.

[0064] In steps S110 to S130 of some embodiments, in the debugging mode, the system scans the storage device of the vehicle, scans the data storage area of ​​the vehicle system, identifies and extracts all stored personal information. This information may include music playback records, navigation history, address book, etc. After extracting the stored personal information, the system will classify the personal information by category to obtain different data types so that users can view and manage them more easily. Users can view the classified personal information in the data management interface and select the data type they want to delete (such as music, navigation records or address book, but not limited to this), that is, the target deleted data.

[0065] In step S200 of some embodiments, the number of repeated erases for each data type that is desired to be deleted can be set. Optionally, the user can specify the number of repeated erases for each data type to enhance the security of data deletion and prevent data recovery. In order to increase the difficulty of data being irrecoverable, the user can specify to select three erases and seven erases or other times of erases. Exemplarily, three erases may include: first overwriting each addressable location with a random bit pattern, then overwriting each addressable location on the storage device with binary zeros, and finally overwriting each addressable location with binary ones. After each overwriting operation, verification can be performed to ensure that the previous overwriting has been successfully completed. The seven erases may include: first, overwriting each addressable location with binary zero; second, overwriting each addressable location with binary one; third, overwriting each addressable location with a random bit pattern; fourth, overwriting each addressable location with binary zero again; fifth, overwriting each addressable location with binary one again; sixth, overwriting each addressable location with a random bit pattern again; seventh, overwriting each addressable location with a random bit pattern for the last time; after each step, verification can be performed to ensure that the previous step has been successfully completed. By using a different fill pattern each time, the difficulty of data recovery can be increased.

[0066] In some embodiments, step S300 may include but is not limited to steps S310 to S330.

[0067] Step S310, dividing the target deleted data into blocks to obtain a plurality of first data blocks;

[0068] Step S320, performing hash calculation on the first data block to obtain a plurality of third hash values;

[0069] Step S330: merge several of the third Hash values ​​to obtain the first Hash value.

[0070] In steps S310 to S330 of some embodiments, the target deleted data to be deleted is provided to a hash algorithm, and a hash operation is performed to generate a unique identifier of the data - a hash value. The core operation of calculating the hash value is to use a hash algorithm (such as SHA-256 or MD5) to process the extracted target deleted data to generate a unique hash value. During the calculation process, the target deleted data is divided into several blocks (usually the same size as the storage block) through the hash algorithm to obtain several first data blocks, and then each first data block will participate in the hash calculation to obtain several third hash values, and finally the third hash values ​​are synthesized into a unique hash value to obtain the first hash value. The calculated hash value is the unique identifier of the target deleted data. The embodiment of the present invention utilizes the characteristics that the hash value can be used to verify the integrity and consistency of the data. In the subsequent steps, the hash value is calculated and compared to determine whether the data is deleted, thereby improving the accuracy and reliability of data clearing.

[0071] For example, taking the case where a user chooses to delete a file named photo.jpg, the process of obtaining the first hash value of the target deleted data includes: the vehicle system extracts the file content of the target deleted data photo.jpg from the vehicle computer storage, and obtains the file content (data block), file size (such as 1MB), and file path (such as / mnt / sdcard / photos / photo.jpg). The file content is divided into several first data blocks, and each first data block can be 4KB or 8KB in size. Then, hash calculation is performed on the extracted first data block. Taking the SHA-256 algorithm as an example, the vehicle system performs hash calculation on all first data blocks of photo.jpg one by one, and combines the calculated several third hash values ​​into a unique hash value. The vehicle system will generate a 256-bit (32-byte) first hash value. Assume that the result is: d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2d2. This hash value will be used as the unique identifier of the target deleted data photo.jpg file for subsequent data integrity verification.

[0072] The hash value is the only representation of the data, which means that any slight change to the data will result in a change in the hash value, thus ensuring the accuracy and reliability of data deletion. This step is also a key technical measure to ensure that the data can be tracked and verified during the subsequent deletion process.

[0073] In some embodiments, the vehicle system may also store the calculated hash value in a recovery log or recovery record. In the operation of storing the hash value, the stored parameters may include the hash value and its corresponding data block information. By storing the hash value, the integrity and consistency of the data can be ensured, which is used for verification and validation during the recovery process. In the embodiment of the present invention, it is also used for hash value comparison to determine whether the target deleted data has been cleared.

[0074] In some embodiments, after completing the calculation of the hash value, the vehicle system can also feedback the hash calculation result to the user. The feedback result parameters returned may include but are not limited to the calculation result (success / failure), hash value (if the calculation result is successful), and error message (if the calculation result is failed). If the calculation is successful, the vehicle system displays the calculated hash value and allows the user to continue to delete or restore data. If the calculation fails, the vehicle system prompts the cause of the error and suggests that the user try again.

[0075] In step S400 of some embodiments, in response to a data erasure instruction from a user, a pre-set data erasure program is pushed to the vehicle-mounted system, and the program is responsible for executing data deletion and filling operations to ensure that the data is completely cleared.

[0076] In some embodiments, step S500 may include but is not limited to steps S510 to S540:

[0077] Step S510, obtaining the erasure area of ​​the target deleted data;

[0078] Step S520, locking and marking the erasure area;

[0079] Step S530, generating a random second data block according to the size of the erased area;

[0080] Step S540: writing the second data block into the locked erase area.

[0081] In steps S510 to S520 of some embodiments, according to the path of the target deleted data, the file or area of ​​the target deleted data, i.e., the erase area, is obtained, and the system locks and marks the data erase area that needs to perform the erase operation. The erase area usually includes the location of the target deleted data or an idle storage area.

[0082] In step S530 of some embodiments, the system generates a random data block, i.e., a second data block, according to the size of the erased area. The size of the generated random data block is equal to the size of the target erased area. For example, if the target area is 4KB, the system will generate a 4KB random byte sequence. The content of the generated random data block is completely unpredictable to ensure that the target deleted data is overwritten.

[0083] In step S540 of some embodiments, the random data in the generated second data block is written into the locked erase area.

[0084] The data erasure program can clear the data in the user-specified area to ensure that the data cannot be recovered. By overwriting the original data, it prevents it from being recovered, ensuring the security and irrecoverability of the data. At the same time, random data is used for filling. It fills the storage area with unpredictable data to overwrite the original data. The recovery tool cannot recognize or reconstruct the original data, so the possibility of recovery is extremely low, ensuring that the deleted data cannot be retrieved by the recovery tool.

[0085] In some embodiments, step S500 may also include but is not limited to step S550:

[0086] Step S550, determines whether the number of repeated erases is reached. If not, returns to the step of executing the data erase program on the target deleted data according to the number of repeated erases. If the number of repeated erases is reached, stops the data erase program and deletes the second data block written in the erase area.

[0087] In step S550 of some embodiments, the system will check whether the number of repeated erases and writes specified by the user has been reached. If the specified number of repeated erases and writes has not been reached, the data erase program will continue to perform the filling operation until the set number of times is reached. Once the specified number of repeated erases and writes is reached, the system will stop the data erase program. Subsequently, the filled data will be deleted to release storage space to ensure that the original target deleted data cannot be restored.

[0088] In step S600 of some embodiments, the system will recalculate the hash value of the deleted area, that is, calculate the second hash value of the erased area corresponding to the original target deleted data to confirm that the data has been successfully erased and cannot be restored. This process provides users with additional security to ensure that personal information is completely deleted.

[0089] In step S700 of some embodiments, the hash value calculated before confirming the deletion of the target deleted data and the hash value of the erased area obtained after completing the data clearing program are compared, that is, the first hash value and the second hash value are compared. If the second hash value is the same as the first hash value, it is necessary to return to the step of pushing the preset data erasing program to the vehicle system to perform a second clearing of the data. If the second hash value is different from the first hash value, the target deleted data has been cleared, and the current smart connected vehicle personal information data clearing process can be ended.

[0090] refer to Figure 2 , Figure 2An optional implementation process of clearing personal information data of an intelligent connected vehicle provided by an embodiment of the present invention is illustrated as follows:

[0091] S1. Enter the vehicle system in debugging mode;

[0092] S2. Control the vehicle system to retrieve and classify personal information to ensure the integrity of the information;

[0098] S44, the system feeds back the hash calculation result to the user;

[0099] S5, push the data erasing program to the vehicle system;

[0100] S6. Execute the data erasure program to fill the data partition:

[0101] S61, locking and marking the data area where the erase operation needs to be performed;

[0102] S62, the system generates a random data block of the same size as the target erasure area according to the size of the target erasure area;

[0103] S63, writing the generated random data into the locked target data area;

[0104] S7, judging whether the number of repeated erasing and writing has been reached, if not, the program will continue to perform the filling operation until the set number of times is reached;

[0105] S8, stop erasing, delete the filled data, and recover the space;

[0106] S9. Recalculate the data hash value of the deleted area to confirm that the data has been successfully erased and cannot be recovered. Compare the new hash value with the hash value calculated in the above step S4. If the hash value of step S9 is the same as the hash value of step S4, return to step S5. If they are not the same, end the process.

[0107] It should be noted that in each specific implementation of the present application, when it comes to the need to perform relevant processing based on data related to user identity or characteristics such as user information, user behavior data, user historical data, and user location information, the user's permission or consent will be obtained first, and the collection, use, and processing of these data will comply with relevant laws, regulations, and standards.

[0131] 2. In the data erasure process, the embodiment of the present invention utilizes the unpredictability of random data filling, uses random data for filling, and overwrites the original data. Since the filling content is randomly generated, the recovery tool cannot recognize or reconstruct the original data, so the possibility of recovery is extremely low. And random data filling complies with multiple international security erasure standards. In addition, the recovery tool relies on the traces of the original data for recovery, while random filling can ensure that there are no traces for recovery, which increases the difficulty of data unrecoverability.
