Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile information security, and in particular to a vehicle image and video desensitization method based on task decomposition. BACKGROUND

[0002] With the rapid development of intelligent and connected vehicle technology, vehicles will collect a large amount of in-vehicle and out-vehicle video and image data through on-board sensors to achieve automatic driving functions and personalized intelligent cockpit functions. These data are crucial for improving vehicle safety performance, optimizing driving experience, and supporting the construction of intelligent transportation systems. However, since the video and image data contain sensitive information such as license plates and facial information, they may infringe upon personal privacy and property safety, and therefore strict protection measures must be taken to prevent data leakage when handling and sharing these data. The State has proposed the "in-vehicle processing principle" and "desensitization processing principle" in the "Provisions on the Management of Automobile Data Security (Trial)", starting to restrict the information collection behavior of vehicle manufacturers.

[0003] The purpose of intelligent and connected vehicle video desensitization technology is to process video content without damaging the original value of the data, so as to eliminate or blur sensitive information. This technology needs to be able to automatically identify and distinguish sensitive content in the video, including but not limited to faces, license plate numbers, specific landmark buildings, and other elements that can be used to track personal identity or location.

[0004] Current desensitization methods generally involve centralized desensitization processing of data at the vehicle communication outlet before uploading the data to the cloud or server. This means that the original sensitive data has been transmitted between multiple controllers in the in-vehicle network, which is not completely secure, and there is a potential information security risk of interception and theft. SUMMARY

[0025] A lowest-level controller is determined based on the superior-inferior correlation, and the unexecuted target desensitization task is executed by the lowest-level controller; wherein the lowest-level controller is connected with an external device.

[0026] Optionally, the executable target desensitization task actually executed by the controller is determined according to the running state, including:

[0027] The resource space required by the controller to execute the target desensitization task is obtained from a preset desensitization algorithm library;

[0028] The running state including processor usage, memory occupancy and storage occupancy is obtained to determine the remaining resource space of the controller;

[0050] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0051] The specific implementation of the concept of the present application will be described below.

[0052] Reference is made to Figure 1 The embodiment of the present application provides a vehicle image and video desensitization method based on task decomposition, which comprises the following steps.

[0053] Step 100, obtaining desensitization data including vehicle images and videos;

[0054] Step 102, generating a desensitization requirement list of the controllers contained in the vehicle according to the desensitization data; wherein the desensitization requirement list includes the desensitization level requirement and the desensitization task of the controllers; there is a superior-inferior association relationship between the controllers;

[0055] Step 104, determining the target desensitization task of the controllers according to the superior-inferior association relationship and the desensitization requirement list of each controller;

[0056] Step 106, the controllers sequentially execute the target desensitization task according to the superior-inferior association relationship, and complete the desensitization.

[0057] In the embodiment of the present application, after obtaining the desensitization data of the vehicle image and video, the desensitization requirement list including the desensitization level requirement and the desensitization task of each controller of the vehicle is generated, and then the target desensitization task of each controller can be determined according to the superior-inferior association relationship between the controllers and the desensitization requirement list, so that each controller sequentially executes the target desensitization task according to the superior-inferior association relationship to complete the desensitization. In this way, the desensitization operation is implemented on multiple nodes in the vehicle internal network in stages, which can execute the desensitization processing as early as possible in the early stage of data generation, thereby shortening the transmission path of sensitive data and increasing the information security protection capability of the vehicle. At the same time, the requirements of each node for the data desensitization level are considered to further protect the implementation of the original function of each node.

[0058] The execution manner of each step is described below. Figure 1

[0059] Firstly, in step 100, the desensitization data is the in-vehicle and out-vehicle video and image data collected by the vehicle-mounted sensor. For example, the desensitization data includes the driver video and image collected by the front camera; the desensitization data includes the out-vehicle license plate video and image collected by the front camera.

[0060] For step 102, the desensitization requirement list of the controller contained in the vehicle is generated according to the desensitization data, including:

[0061] For each controller, the following is executed:

[0062] The data frequency requirement of the controller and the desensitization level requirement of the desensitization data are determined;

[0063] The data frequency requirement, the desensitization level requirement and the desensitization task corresponding to the desensitization level requirement of the controller are determined as the desensitization requirement list of the controller.

[0064] Specifically, in step 102, a desensitization requirement list is established for each controller of the desensitization data transmission link, and each controller establishes a desensitization requirement list based on the needs of its own function. This step can be designed in advance during the design and development stage of the vehicle and the desensitization requirement list can be fixed in each controller, or the desensitization requirement list can be generated in real time by the controller in the vehicle based on the actual needs and updated with the superior-inferior controllers (i.e., the desensitization requirement list of the adjacent controllers can be obtained). The data frequency requirement refers to the data frequency required by each controller to realize its own function, and the data transmission of the data frequency requirement needs to be realized by the controller. The highest desensitization level requirement in the desensitization requirement list can meet the needs of the function of the controller, i.e., the desensitization level requirement of the controller other than the lowest controller of the vehicle is a declaration of the upper limit of the desensitization intensity.

[0065] ​It should be noted that the superior-inferior association relationship specifically refers to data flowing from the superior to the inferior. For example, as shown in the electronic and electrical architecture of the vehicle in Figure 2 After the driver image and video are collected by the main driver camera, the data flow direction is: driver monitoring system controller- autonomous driving domain controller- central gateway- vehicle telematics system (Tbox)- external cloud server; therefore, for the vehicle, the top-level controller is the driver monitoring system controller, the next-level controller is the autonomous driving domain controller, and the lowest-level controller is the vehicle telematics system (Tbox).

[0066] In the present application, the desensitization level requirement and the desensitization task can be set by the vehicle designer. For example, as shown in the previous example, for the driver image and video, the desensitization level requirement according to the desensitization strength from high to low is: Lv4 image deletion and conversion to fuzzy value, Lv3 complete masking, Lv2 blurring, Lv1 feature retention, and Lv0 original data; and the corresponding desensitization task name is driver anonymization. However, the desensitization level requirement is not limited to these. Specifically, for example, as shown in the desensitization requirement list of the controllers of the vehicle in Figure 2

[0067] Table 1

[0068]

[0069] As can be seen from Table 1, the driver monitoring system controller needs desensitized data with a desensitization level requirement of Lv0 to complete its own function; the autonomous driving domain controller needs desensitized data with a desensitization level requirement of Lv1 at most to complete its own function; the central gateway needs desensitized data with a desensitization level requirement of Lv2 at most to complete its own function, and it can complete its own function with a desensitization level requirement of Lv1 or Lv0.

[0070] For step 104, according to the superior-inferior association relationship and the desensitization requirement list of each controller, the target desensitization task of the controller is determined, including:

[0071] Based on the desensitization requirement list, the first desensitization level requirement of the controller is obtained;

[0072] According to the superior-inferior association relationship, the second desensitization level requirement of the next-level controller of the controller is obtained based on the desensitization requirement list;

[0073] It is judged whether there is a desensitization level requirement greater than the first desensitization level requirement in the second desensitization level requirement;

[0074] ​If the judgment result is yes, the desensitization task corresponding to the desensitization level requirement is determined as the target desensitization task of the controller; wherein the desensitization level requirement is the desensitization strength of the target desensitization task.

[0075] It should be noted that the desensitization strength is the degree of desensitization processing when the target desensitization task is executed, and the data level after desensitization processing has a corresponding desensitization level requirement.

[0076] In the present application, the target desensitization task is a desensitization operation that can be executed by the controller after completing its own function, and the desensitization level requirement corresponding to the target desensitization task is higher than the desensitization level requirement of the desensitized data required by the controller itself. If the desensitization level requirements in the desensitization requirement list of the controller and the next level controller are the same, the controller does not need to execute the desensitization task, and there is no target desensitization task. Once the desensitization level requirement of the next level controller is higher than that of the controller, the controller can perform a step of desensitization processing on the desensitized data after completing its own function, while meeting the desensitization level requirement required by the next level controller to complete its own function.

[0077] As described in the foregoing example, for example, the desensitization level requirement of the data in the desensitization requirement list of the automatic driving domain controller is Lv1, and the desensitization level requirement of the data in the desensitization requirement list of the next level central gateway is Lv1, Lv2, and Lv3. The automatic driving domain controller can execute a target desensitization task with a desensitization strength of Lv2 or Lv3, or not execute a desensitization task.

[0078] In the present application, for any controller, the first desensitization level requirement is the desensitization requirement for data under the premise of meeting the function of the controller itself, and the first desensitization level requirement is at least one. However, when the data is transmitted to the next level controller, it is also necessary to ensure that the data provided by the previous level controller can meet the sensitive data use requirement of the next level controller, so as to prevent the next level controller from being unable to normally carry out the function due to excessive desensitization. Therefore, based on the first desensitization level requirement and the second desensitization level requirement, all possible target desensitization tasks that can be executed by the current controller are determined, so as to ensure the smooth operation of the next level controller. As described in the foregoing example, for example, the desensitization level requirement of the data in the desensitization requirement list of the automatic driving domain controller is Lv1, and the desensitization level requirement of the data in the desensitization requirement list of the next level central gateway is Lv2. If the automatic driving domain controller executes a target desensitization task with a desensitization strength of Lv3, it will cause excessive desensitization and affect the normal operation of the central gateway.

[0079] In step 106, the controller sequentially executes the target desensitization task according to the upper and lower level association relationship, including:

[0080] Obtaining the running state of the controller;

[0081] determining, according to the running state, an executable target desensitization task actually executed by the controller from the target desensitization task;

[0082] sequentially executing the executable target desensitization task according to the superior-inferior correlation relationship;

[0083] determining, based on the executable target desensitization task and the target desensitization task of each controller, an unexecuted target desensitization task;

[0084] determining the lowest-level controller based on the superior-inferior correlation relationship, and executing the unexecuted target desensitization task by the lowest-level controller; wherein the lowest-level controller is connected with the external device.

[0085] In the present application, the controller needs to execute the additional target desensitization task by using the remaining resources on the premise of ensuring the effective operation of its own function, and therefore it is necessary to determine whether the target desensitization task of the controller can be additionally executed according to the actual running state of the controller. At the same time, in order to ensure that the desensitized data is completed before being transmitted to the external device, the uncompleted target desensitization task needs to be forcibly implemented by the lowest-level controller.

[0086] It should be noted that the desensitization processing of the data in the prior art is completed by the lowest-level controller of the vehicle, and therefore the lowest-level controller of the present application can implement the uncompleted target desensitization task.

[0087] In a preferred embodiment, for step 106, determining, according to the running state, an executable target desensitization task actually executed by the controller from the target desensitization task includes:

[0088] obtaining a resource space required by the controller for executing the target desensitization task from a preset desensitization algorithm library;

[0089] obtaining the running state including the processor usage rate, the memory occupancy rate and the storage occupancy rate to determine the remaining resource space of the controller;

[0090] determining whether there is a resource space smaller than the remaining resource space;

[0091] if the determination result is yes, determining the target desensitization task corresponding to the resource space as the executable target desensitization task;

[0092] if the determination result is no, the controller does not execute the target desensitization task.

[0093] Specifically, for the same target desensitization task, the resource spaces required by different desensitization algorithms are different. The resource space smaller than the remaining resource space means that the remaining resource space of the controller can allow the target desensitization task to be executed.

[0094] In the present application, each controller should primarily complete its own functional task, and then select the desensitization task that can be executed under the premise of meeting the data frequency requirement of the next level, so it is necessary to comprehensively consider the processor usage rate, memory occupancy rate and storage occupancy rate to further confirm the remaining resource space of the controller. If the remaining resource space of the controller cannot realize any target desensitization task, the desensitization task is not executed, and the most subordinate controller is forced to execute.

[0095] For example, as described in the foregoing example, the target desensitization task of controller A includes Lv1 driver anonymization and Lv2 driver anonymization for the driver, and the resource space required for executing the Lv2 driver anonymization is less than the remaining resource space, so the Lv2 driver anonymization is selected as the executable target desensitization task.

[0096] In a preferred embodiment, the executable target desensitization task is executed in sequence according to the superior-inferior association relationship, including:

[0097] After the controller executes the executable target desensitization task, a desensitization execution list of the controller including the executed target desensitization task is generated;

[0098] The desensitization execution list is transmitted to the next level controller, and the desensitization execution list is updated by the next level controller based on the executed target desensitization task.

[0099] In the present application, the controller sends the processed sensitive data and the desensitization execution list to the next level controller, so that a control table (i.e. desensitization task list) of completed desensitization level requirements and completed desensitization intensity is stored in each controller to identify the desensitization task execution of the sensor of the previous level. The desensitization task execution list is a dynamically generated list, which is transmitted to the next level controller along with the processed sensitive data and updated, so that the most subordinate controller can count the unexecuted target desensitization task, and the most subordinate controller can complete all desensitization tasks.

[0100] It should be noted that the desensitization execution list includes the name of the desensitization task and the completion mode of the executable target desensitization task. For example, as described in the foregoing example Table 1, the desensitization task list of each controller of the vehicle for the driver image and video is shown in Tables 2 to 4. Figure 2

[0101] Table 2

[0102]

[0103] Table 3

[0104]

[0105] Table 4 ​

[0106]

[0107] In a preferred embodiment, further comprising:

[0108] If the current controller does not perform the target desensitization task, the desensitization execution list of the upper-level controller is transmitted to the current controller according to the upper-and-lower-level association relationship, and the name of the controller included in the desensitization execution list is updated to the name of the current controller.

[0109] It should be noted that the upper-level controller is the upper-level controller of the current controller.

[0110] In the present application, if the controller evaluates that the actual running state cannot achieve further desensitization, the situation that the upper-level controller has executed is copied in the desensitization execution list of the controller, that is, the desensitization execution list of the upper-level controller is transmitted to the lower-level controller, so as to ensure that the description in the list is consistent with the actual desensitization situation of the data in the transmission.
