In actual system or server product execution, the method order shown in the embodiments can be executed in sequence or in parallel (for example, in a parallel processor or multi-thread processing environment). The data management method in the embodiments of the present application is applied to a vehicle terminal, and specifically as shown in Figure 2 The method can include:

[0064] S201: receiving a target data acquisition request sent by a target application, the target data acquisition request carrying first identification information of target data.

[0066] In an optional embodiment, the target data can be vehicle terminal data in the vehicle 101 corresponding to the target data acquisition request. After the vehicle terminal receives the target data acquisition request sent by the target application, the target data can be determined from the multiple vehicle terminal data in the vehicle terminal based on the first identification information carried by the target data acquisition request.

[0069] Specifically, the target data includes the second identification information, and the vehicle terminal can determine the target data from the multiple vehicle terminal data according to the first identification information carried by the target data acquisition request. In other words, the vehicle terminal can determine whether the second information identification exists in the multiple vehicle terminal data based on the first identification information, and if the second information identification exists, it can be determined that the target data corresponding to the target data acquisition request exists in the multiple vehicle terminal data, that is, the first identification information in the target data acquisition request and the second identification information of the target data in the vehicle terminal are the same.

[0073] S303: Determine the data storage location information of the target data according to the data source information and the data type information of the target data.

[0074] For the target data detected by the vehicle sensor, the security classification information of the target data can be determined by judging the source information and type information of the target data, i.e., whether the target data belongs to personal privacy data, national security data, national core data or general data, etc. After determining the security classification information of the target data, the data storage location information of the target data can be determined according to the security classification information of the target data, such as determining the data storage location information of the target data with high security classification information as not allowing static storage, only allowing temporary storage in the cache, or determining as only allowing it to be stored in a specific storage module with high security, which can prevent the target data with high security classification information from being leaked and maliciously collected, realize the management of the storage security of the target data, and improve the security of the target data.

[0075] Figure 4 is a flowchart of a method for determining data storage location information of target data provided by an embodiment of the present application. In the embodiment of the present application, the method can include:

[0076] S401: Determine the data security level information of the target data according to the data source information and data type information of the target data.

[0077] For vehicle basic information such as vehicle model information, license plate number, and driving speed information, etc., the subsequent and storage thereof generally will not affect individuals and the country, but for in-vehicle cameras, in-vehicle microphones, geographic location or business-related data, etc., may infringe on personal privacy or affect national security. Therefore, in an optional embodiment, the data security level information of the target data can be determined according to the influence degree on personal privacy security and national security, which can include general data, personal privacy data, national important data and national core data, etc. with security levels from low to high. The storage and transmission control permissions of target data with different data security levels are also different. Of course, the data security level information can also include other classification methods, which are not limited in the embodiment of the present application.

[0078] Optionally, according to different data security level information, it can be determined whether the target data is allowed to be statically stored. If it is allowed to be statically stored, the corresponding data storage module can be further determined according to the corresponding data security level information.

[0079] Optionally, according to different data security level information, it can be determined whether the target data can be transmitted. If it can be transmitted, it can be further determined whether the receiving end is a target application, etc.

[0080] S403: Determine the data storage location information of the target data according to the data security level information.

[0081] In an optional embodiment, for target data such as personal privacy data of a high data security level, national important data, and national core data, a first storage mapping relationship between the target data and a specific data storage module with good security performance can be established; for other data except the target data, a second storage mapping relationship between the other data and other data storage modules can be established.

[0082] In an optional embodiment, in the S403, the storage location information can be determined according to the data security level information and the first storage mapping relationship and the second storage mapping relationship.

[0083] For example, for target data such as personal privacy data of a high data security level, national important data, and national core data, the data storage location information of the target data can be determined as a specific data storage module with good security performance according to the first storage mapping relationship; for other data except the target data, the data storage location information of the other data can be determined as other data storage modules according to the second storage mapping relationship.

[0084] In another optional embodiment, for target data such as personal privacy data of a high data security level, national important data, and national core data, a third storage mapping relationship between the target data and a cache module that cannot be statically stored and can only be temporarily cached can be established; in the S403, the storage location information can be determined according to the data security level information and the third storage mapping relationship; for target data of a high data security level, the data storage location information of the target data can be determined as the cache module according to the third storage mapping relationship.

[0085] In this way, the data storage location information of the target data is determined according to the data security level information of the target data, the corresponding data storage location can be determined according to the different security levels of the target data, and the security of storage control of the target data is improved.

[0086] S305: determining a feature parameter of the target data according to the data source information, the data type information, and the data storage location information of the target data, wherein the feature parameter includes a data source parameter, a data type parameter, and a data storage parameter.

[0087] In an optional embodiment, a data source parameter mapping relationship between the data source information of the target data and the data source parameter, a data type parameter mapping relationship between the data type information and the data type parameter, and a data storage parameter mapping relationship between the data storage location information and the data storage parameter can be established.

[0088] In an optional embodiment, in the S305 above, the various characteristic parameters of the target data can be determined according to various pre-established parameter mapping relationships.

[0089] As an example, the data source parameter can be determined according to the data source information of the target data and a data source parameter mapping relationship, the data type parameter can be determined according to the data type information of the target data and a data type parameter mapping relationship, and the data storage parameter can be determined according to the data storage location information of the target data and a data storage parameter mapping relationship.

[0090] For example, the data source information of the target data can be the port number information of the collection module of the target data such as a vehicle sensor, and the port number information of the target data can be uniquely determined according to a data source parameter determination mapping relationship to determine the data source parameter; the data type information can be the format information of the target data collected by the collection module of the target data such as a vehicle sensor, and the type information of the target data can be uniquely determined according to a data type parameter determination mapping relationship to determine the data type parameter.

[0091] In the embodiments of the present application, the characteristic parameters of the target data can further include a data security classification parameter and a data transmission parameter, Figure 5 FIG. 1 is a flow diagram of a vehicle-end data management method provided by an embodiment of the present application, which can further include:

[0092] S501: determining the data security level information of the target data according to the data source information and the data type information of the target data.

[0093] S503: determining the data transmission information of the target data according to the data security level information.

[0094] In an optional embodiment, for target data such as personal privacy data, national important data, and national core data with a high data security level, a first transmission mapping relationship between the target data and a first target application can be determined; for data other than the target data such as personal privacy data, national important data, and national core data with a high data security level, a second transmission mapping relationship between the data and a second target application can be determined.

[0095] In an optional embodiment, in the S503 above, the data transmission information can be determined according to the pre-established first transmission mapping relationship and the second transmission mapping relationship.

[0096] For example, for target data such as personal privacy data with a high data security level, important national data, and core national data, the data transmission information of the target data is determined as a target application program in the vehicle or a specific target application program outside the vehicle according to the first transmission mapping relationship, wherein the target application program in the vehicle can be a WeChat application program in the vehicle or a navigation application program in the vehicle, and the specific target application program outside the vehicle can be a cloud server of a vehicle manufacturer, a national monitoring platform, or a cloud of a vehicle operation company. For other data except the target data such as personal privacy data with a high data security level, important national data, and core national data, the data transmission information of the data is determined as a target application program in the vehicle or a specific target application program outside the vehicle according to the second transmission mapping relationship.

[0097] S505: According to the data security level information and the data transmission information of the target data, the data security level parameter and the data transmission parameter of the target data are determined.

[0098] In an optional embodiment, a data security level parameter mapping relationship between the data security level information and the data security level parameter of the target data and a data transmission parameter mapping relationship between the data transmission information and the data transmission parameter can be established.

[0099] In an optional embodiment, in the above S505, various feature parameters of the target data can be determined according to the mapping relationship of various parameters determined in advance.

[0100] For example, the data security level parameter can be determined according to the data security level information and the data security level parameter mapping relationship of the target data, and the data transmission parameter can be determined according to the data transmission information and the data transmission parameter mapping relationship of the target data.

[0101] According to the data security level information and the corresponding transmission mapping relationship, whether the target data with different security levels can be transmitted to the outside of the vehicle or whether the target data with different security levels is transmitted to the specific target application program outside the vehicle can be controlled, so that the transmission of the target data with different security levels is controlled, the risk of leakage of the target data is reduced, and the security of data transmission control is improved.

[0102] In the embodiment of the application, the feature parameters of the target data can further include a data sequence number parameter, Figure 6 is a flowchart of a vehicle-end data management method provided by the embodiment of the application. The vehicle-end data management method can further include:

[0103] S601: Determine the collection time of the target data.

[0104] In the embodiment of the application, the target data can include the collection time, and the collection time is the timestamp information when the vehicle sensor collects the target data.

[0105] S603: Determine the data sequence number parameter according to the collection time of the target data.

[0106] Through the data sequence number parameter determined by the collection time, the sequence number parameter of the data from the same source is unique, and for various data from different sources, the data sequence number parameter is combined with other characteristic parameters such as the data source parameter, and is also unique, so that the second identification information generated by combining the characteristic identification corresponding to various parameters including the data sequence number is uniquely determined, which facilitates subsequent data traceability and accurate control through the uniquely determined second identification information.

[0107] In the embodiment of the application, the data sequence number parameter can be determined according to the collection time of the target data. For example, the collection time of the target data is 2022-02-28 19:32:03, the timestamp information corresponds to 1646047923 seconds (s), the decimal number 1646047923 corresponding to the timestamp information is converted into a hexadecimal number, and the hexadecimal number 621CB2B3 corresponding to the timestamp information is obtained. The hexadecimal number 621CB2B3 can be determined as the data sequence number parameter; of course, the data sequence number parameter can also be determined by other ways according to the collection time of the target data.

[0108] In this way, the data sequence number parameter of the target data can be quickly and conveniently determined based on the collection time of the target data.

In other words, the feature identification includes the feature parameter and the combination sequence information.
