DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions and advantages of the present application clearer, further detailed explanations are made below with reference to the embodiments and the accompanying drawings.

[0017] It should be noted that, unless otherwise defined, technical terms or scientific terms used in the embodiments of the present application should be understood as their common meanings to those skilled in the art to which the present application belongs.

The terms “connect” or “connected” and similar terms do not mean only physical or mechanical connections, but can also include electrical connections, whether direct or indirect. The terms “upper”, “lower”, “left”, “right”, and the like only represent relative positional relationships, which can change accordingly when the absolute positions of the described objects change.

[0018] In this document, it should be understood that any number of elements in the accompanying drawings are used for illustration only and not limitation, and any naming is only for differentiation and does not have any limiting meaning.

[0019] Based on the above description of the background art, the following situations exist in the related art: With the rapid development of intelligent vehicle technology, vehicles are not just simple means of transportation, but have gradually become highly integrated information and entertainment centers. Modern vehicles are usually equipped with advanced in-vehicle information systems, such as navigation systems, multimedia playback devices, vehicle communication and Internet access functions, etc. These systems can collect and process a large amount of personal information and driving habit data, thereby improving the driving experience and the efficiency of using the vehicle. However, as the degree of intelligence of vehicles increases, the privacy protection of vehicle owners has become increasingly prominent. In the vehicle-machine interconnection scenario, the vehicle screen is used to display mobile phone content and control the collection of applications in the vehicle screen. When the user uses the screen projection function, other passengers can see the user's screen display content, which may lead to the unintended disclosure or misuse of the vehicle owner's private information.

[0020] Screen mirroring technology allows users to project the application interface from their mobile phone onto the vehicle's central control screen for a more convenient operating experience. Screen mirroring refers to the technology of transmitting and displaying the screen content of a mobile device to other display devices in real time. In vehicle-to-vehicle connectivity, the mobile application interface will be fully displayed on the vehicle's central control screen, including all application icons, interface elements, and functional areas. Privacy protection mode is a system security mechanism that automatically adjusts application permissions and function access restrictions when specific conditions are detected to protect user privacy information from unauthorized access.

[0021] Among related technologies, vehicle-to-everything (V2X) technology poses serious privacy and security risks. When a car owner's mobile phone is connected to the vehicle's infotainment system, all applications on the phone are projected onto the vehicle's central control screen. Passengers in the front passenger seat or other passengers can freely click and operate these applications, including viewing sensitive data such as call logs, text messages, and bank account information. This design lacks a permission control mechanism tailored to different user roles, failing to effectively protect the driver's privacy.

[0022] Therefore, how to effectively protect the privacy of car owners and passengers while ensuring the convenience brought by vehicle intelligence has become an urgent problem to be solved. Although there are some privacy protection solutions in related technologies, such as actively enabling privacy mode to restrict access to certain functions, these solutions often lack flexibility and intelligence. They cannot provide personalized privacy protection based on the needs of car owners and users. That is, if privacy mode is enabled to restrict access to certain functions when multiple people are detected in the car, it may affect the operation of the car owner and bring a poor privacy protection experience to the user.

[0023] The vehicle-to-everything (V2X) privacy protection method, electronic device, and vehicle provided in this application determine the privacy protection mode for each screen-casting application based on the user's settings, obtaining personalized configuration data. In response to successful V2X detection, the vehicle's passenger situation is determined. If the passenger number is greater than or equal to a preset threshold and a front passenger is present, a privacy protection mode is entered. Privacy protection control for the screen-casting applications is then implemented based on the personalized configuration data and in-vehicle imaging. The personalized configuration data is determined based on the user's settings, fully satisfying the user's personalized privacy needs. Privacy protection is enabled and disabled based on the passenger situation, avoiding excessive privacy protection from affecting normal user operation. After entering privacy protection mode, privacy protection control for screen-casting applications is implemented based on personalized configuration data and in-vehicle imaging, refining privacy protection to individual screen-casting applications. This allows for targeted privacy protection for different screen-casting applications based on the user's personalized privacy needs. Different screen-casting applications have different privacy protection strategies, satisfying the user's personalized privacy protection requirements.

[0024] The following describes in detail, with reference to the accompanying drawings, the privacy protection method for vehicle-to-machine interconnection provided by the embodiments of this application.

[0025] In some embodiments, such as Figure 1 As shown, the privacy protection methods for vehicle-to-everything (V2X) connectivity include: Step 101: Determine the privacy protection method for each screen mirroring application based on the user's settings to obtain personalized configuration data.

[0026] In practical implementation, in scenarios with multiple passengers, if the car owner actively uses certain functions without hesitation, it indicates that the car owner is not afraid of the corresponding privacy information being leaked. However, there is a possibility that passengers may use the screen mirroring function to control and use the screen mirroring application in the screen mirroring interface (i.e., the application that mirrors the mobile phone screen to the vehicle's central control screen) to obtain information that the user wishes to hide. Compared to the privacy information accidentally leaked when the car owner uses the function, the targeted acquisition by passengers is more likely to cause the leakage of privacy information and poses a greater security risk. Therefore, this application embodiment mainly focuses on the scenario in which passengers actively obtain the car owner's privacy through the screen mirroring application in a multi-person scenario and provides targeted privacy protection.

[0027] Privacy protection for screen mirroring applications is strongly correlated with the personalized privacy protection needs of users (car owners). This is because only car owners know which applications contain private information that they do not want others to access. Therefore, it is necessary to set up corresponding personalized configuration modules to provide car owners with personalized privacy protection strategies.

[0028] The term "vehicle owner" as used in this application should be interpreted broadly. For example, a vehicle owner can include a user who owns and primarily drives the vehicle, a user who does not own the vehicle but is primarily responsible for driving it, or a user who does not own the vehicle but has shared their vehicle key account. It should be understood that any user with driving privileges who requires privacy protection can be considered a vehicle owner as mentioned in this application. Furthermore, it should be understood that in many driving scenarios, the vehicle owner is the driver, sitting in the primary driver's seat of the vehicle.

[0029] Personalized configuration is achieved through a personalized configuration module, which forms the foundation for precise privacy protection. It allows users to set different privacy protection methods for different screen-casting applications according to their own needs. Users can access the privacy settings interface through the in-vehicle central control screen or mobile application to customize the privacy protection methods for various applications. For example, users can set communication applications (such as WeChat and SMS) to the highest protection level, requiring the corresponding application icon to be completely hidden, preventing other passengers from using the application from the outset. Navigation applications (such as Gaode Maps and Baidu Maps) can be set to a medium protection level, displaying the corresponding application icon but prohibiting passengers other than the vehicle owner from accessing the application by manipulating the icon. Media applications (such as Tencent Video and NetEase Cloud Music) can be set to the lowest protection level, displaying and allowing other passengers to access and use the application, with restrictions only on specific functions, such as deleting downloaded audio or video, or changing application settings—high-risk operations. If the user does not set restrictions on corresponding functions, no protection is required by default, and other passengers can use all functions of the lowest-protection screen-casting application by default. This differentiated configuration ensures that the privacy protection strategy meets the actual needs of users, avoiding the degradation of experience caused by a "one-size-fits-all" approach.

[0030] For example, the personalization settings interface typically offers three configuration methods: global settings, application-level settings, and exception management. Global settings allow users to quickly define the default protection level for all applications (generally medium protection level), application-level settings support fine-tuning for individual applications, and exception management can be used to handle special needs in specific scenarios (such as having separate personalized configuration data in children's mode). The system also records the user's selection habits and recommends optimized configuration schemes through intelligent algorithms. For example, if a user frequently hides message notifications while driving, the system may suggest automatically enabling the protection function of communication applications.

[0031] After users complete their personalization settings, the resulting personalized configuration data is stored on the user's local device, eliminating the need to upload it to the cloud and avoiding the security risks inherent in the privacy settings themselves. Simultaneously, the system supports switching between multiple user accounts, allowing different drivers to use their respective privacy preferences, further enhancing the targeted nature of personal privacy protection and achieving personalized privacy safeguards.

[0032] Step 102: In response to the successful detection of vehicle-to-vehicle connectivity, determine the passenger seating situation inside the vehicle.

[0033] In practice, after the vehicle-machine interconnection is successfully completed and the screen of mobile terminals (such as mobile phones) has been projected, it is necessary to further identify the passenger situation in the vehicle, that is, to identify whether there is a risk of privacy leakage due to multiple passengers.

[0034] Multi-passenger vehicles refer to scenarios where two or more passengers travel together. When multiple people are traveling together, there are two main issues. First, the driver and other passengers may not be familiar with each other. In this case, if the driver directly answers or makes a Bluetooth call through the vehicle's infotainment system, relevant call information (such as the caller's identity and phone number) may be displayed directly on the in-vehicle screen, or the call content may be played aloud through the system. These actions can easily lead to the leakage of the driver's privacy. Second, even if the driver and other passengers are familiar with each other, the driver may still not want certain private information to be known by the other passengers. For example, the driver and front passenger may be the husband and wife of a family, while the children are in the back. In this situation, the parents may not want their children to know certain phone conversations. Therefore, in multi-passenger scenarios, protecting the driver's privacy is especially important.

[0035] In the embodiments of this application, multiple passenger scenarios can be identified through various means, and privacy protection operations can be automatically initiated accordingly. For example, multiple passenger scenarios can be identified through seat pressure sensors, visual recognition, voice recognition, seat belt usage status, Bluetooth identifiers of electronic devices, etc. These identification methods are described below.

[0036] Vehicles are typically equipped with seat pressure sensors to detect the number of passengers inside the vehicle. For example, in some embodiments, seat pressure sensors can be used to detect whether a seat is occupied. Exemplarily, if the seat pressure sensor detects that a seat is occupied ("occupied"), then the seat is occupied; if the seat pressure sensor detects that a seat is unoccupied ("unoccupied"), then the seat is unoccupied. More specifically, for example, if the pressure detected by the seat pressure sensor exceeds a certain threshold (e.g., 20 kg), the seat can be considered occupied; otherwise, it is unoccupied. Then, based on the seat occupancy status detected by the pressure sensors of each seat, the total number of passengers in the vehicle can be calculated to determine whether the vehicle is currently occupied by multiple passengers and the seating position of each passenger.

[0037] Optionally, in some embodiments, the vehicle may be equipped with a passive safety management (PSM) subsystem. This PSM subsystem can coordinate and control the pressure sensors of each seat in the vehicle, and obtain the number of passengers and the position of each passenger based on the seat occupancy status detected by each pressure sensor. Furthermore, when it is determined that multiple people are riding in the vehicle, the PSM subsystem can send relevant information to the vehicle's infotainment system to trigger the vehicle to perform privacy protection operations.

[0038] Similar to seat pressure sensors, the number of passengers in a vehicle can also be determined based on the use of seat belts. For example, if a seat belt is detected as being in use, it can be assumed that someone is in that seat. Therefore, by analyzing the usage status of each seat belt, the number of passengers and the location of each passenger can be determined.

[0039] Vehicles are typically equipped with cameras to detect the number of passengers inside. For example, in some embodiments, in-vehicle cameras (e.g., cameras integrated into the vehicle's central control screen) can capture images of the interior to determine the number and location of passengers. Obtaining the number and location of passengers from in-vehicle images can be achieved using various image recognition algorithms in related technologies, which are not limited here. For example, the number and location of passengers can be identified from in-vehicle passenger images using Haar feature cascade classifiers, the CamShift algorithm, density-based techniques, deep learning object detection algorithms, etc., in the field of image recognition. Specific details will not be elaborated here.

[0040] Optionally, in some embodiments, the vehicle may be equipped with an occupancy monitoring system (OMS) to monitor the status of passengers inside the vehicle. The OMS system typically includes an occupancy monitoring camera (OMC) to capture images of the vehicle interior. The OMS system can then identify the number and location of passengers based on the captured images. Furthermore, if the number of identified passengers is greater than two, and the passengers are seated in the front passenger seat, the OMS system can send relevant information to the vehicle's infotainment system to trigger privacy protection operations.

[0041] In some embodiments, the number of passengers in a vehicle can be determined by voice recognition. Each person typically possesses unique voice characteristics (also known as voiceprint features), such as spectral features, temporal features, and formant features. Therefore, in-vehicle sound acquisition devices can be used to collect the voices of passengers, and then certain data processing algorithms can be used to analyze the voiceprint features. Finally, the number and location of passengers in the vehicle can be identified based on these different voiceprint features. For example, passenger A and passenger B have different sound spectra. When passenger A speaks, spectral feature A of passenger A is obtained through certain data processing (e.g., Fourier transform). Similarly, when passenger B speaks, spectral feature B of passenger B is obtained. Based on the different spectral features A and B, the existence of two different passengers, namely passenger A and passenger B, can be identified. Furthermore, since the speed of sound propagation is constant, passenger location can be determined using multiple in-vehicle sound acquisition devices, thereby determining the corresponding passenger location. It should be understood that the identification process described here is merely an example, and those skilled in the art can employ different voice recognition processes to identify the number of passengers in a vehicle according to specific needs.

[0042] In some embodiments, the number of passengers in a vehicle can be determined by the Bluetooth identifiers of passenger electronic devices. These passenger electronic devices refer to personal electronic devices carried by passengers. Each electronic device typically has a unique Bluetooth identifier. For example, the Bluetooth identifier of an electronic device may include the device name, manufacturer data, physical appearance data, etc. Furthermore, each person typically carries only one mobile phone, one tablet, or one smartwatch. Therefore, for example, by detecting the Bluetooth identifiers of electronic devices in the vehicle, the number of mobile phones, tablets, or smartwatches currently in the vehicle can be identified, thereby indirectly determining the number of passengers. Precise positioning based on Bluetooth signals is a relatively mature technology; further determining the location of each Bluetooth device through Bluetooth positioning functionality can serve as the corresponding passenger location.

[0043] As examples, several identification methods for multiple passengers have been described above. However, it should be understood that those skilled in the art can readily conceive of other implementation methods to identify whether multiple passengers are in a vehicle, and this application does not limit such methods. For example, infrared detection can be used to detect the number of heat sources inside the vehicle, thereby identifying whether multiple passengers are in the vehicle and the seating position of each passenger.

[0044] In multi-passenger scenarios, passengers in the front passenger seat may use the in-vehicle central control screen to control screen-sharing applications and obtain private information. Passengers in the rear seats do not have the means to control the central control screen to obtain private information. Even if they forcibly control it, their large movements will alert the driver. The front passenger may operate the screen-sharing application without the driver noticing, resulting in privacy leaks. Therefore, it is necessary to further determine the location of each passenger and use the passenger location to determine whether there is a risk of privacy leakage.

[0045] This step is handled by the in-vehicle environment perception module, which identifies passenger status in real time and provides data support for privacy protection decisions. This module relies on various sensor technologies, including in-vehicle cameras, seat pressure sensors, and infrared sensors, to accurately determine the number, location distribution, and even identity characteristics of passengers inside the vehicle.

[0046] The in-vehicle environment perception module processes sensor data (riding conditions) in real time, analyzing passenger behavior through algorithms. The system not only determines the presence of passengers but also analyzes their seating position, posture, and attention direction to assess the actual risk of privacy breaches. All these analyses are performed locally within the vehicle's infotainment system to prevent sensor data from being transmitted outside the vehicle, ensuring passenger privacy is protected during the perception phase. The riding conditions are then transmitted to the privacy protection execution module as the basis for triggering the privacy protection mode.

[0047] Step 103: In response to the situation where the number of passengers is greater than or equal to the preset number threshold and there is a front passenger, the privacy protection mode is entered, and privacy protection control is performed on the screen projection application based on personalized configuration data and in-vehicle image.

[0048] In practice, after determining the passenger data, it is necessary to determine whether the conditions for entering the privacy protection mode are met. These conditions include passenger number activation and location activation. The passenger number activation condition is used to determine whether it is a multi-person passenger scenario. The location activation condition is used to determine whether the passenger may be controlling the screen projection application.

[0049] First, the system determines whether the passenger count activation condition is met based on the passenger situation. Determining the passenger count ensures that privacy protection is activated only when at least two users are present. If only one user is present, even if they are not in the driver's seat, their phone screen can be projected via the vehicle's infotainment system without any second person viewing or operating the screen, thus eliminating the risk of privacy breaches and requiring no privacy protection. Therefore, a passenger count threshold of two people is selected to determine the activation condition.

[0050] If the number of passengers is less than the threshold, meaning there is only one person or no one in the vehicle, then no one other than the user casting the screen can control the application. This directly confirms that there is no risk of privacy leakage and that the conditions for starting the application with the required number of passengers are not met.

[0051] When the number of passengers is greater than or equal to the threshold, meaning there are two or more users in the car at the same time, it indicates that there are other passengers besides the car owner, and there is a possibility that the screen-sharing application can be controlled by others. This initially indicates a privacy risk. Further analysis based on the passengers' positions is needed to confirm whether a privacy risk truly exists. This requires further determination of the passengers' (users in the car other than the car owner) seating positions. Because rear-seat passengers have limited ability to view the in-car infotainment screen and cannot actively control their phones through the in-car infotainment screen, they cannot obtain the user's hidden private information by actively manipulating the infotainment display. Therefore, the possibility of rear-seat passengers controlling the screen-sharing application without the car owner's knowledge is low. Thus, a privacy risk only exists when there is a passenger in the front passenger seat.

[0052] When determining the location-based activation condition, if the passenger's seat is the front passenger seat (meaning a front passenger is present), and this passenger can control the projection application at any time via the vehicle's central control screen, a privacy risk can be identified, thus fulfilling the location-based activation condition. If the passenger (a user other than the driver) is seated in a non-front passenger seat (e.g., a rear seat), and this passenger can control the projection application at any time via the vehicle's central control screen, a privacy risk can also be identified, thus fulfilling the location-based activation condition.

[0053] When both the number of users and location are met, it indicates that the screen mirroring application can be controlled at any time. Once the privacy protection conditions are met, the application enters privacy protection mode. After entering privacy protection mode, privacy protection control of the screen mirroring application is required based on personalized configuration data and in-vehicle imaging.

[0054] When a touch operation on the screen mirroring application is detected, the in-vehicle image is used to determine the seating posture and attention direction of the driver and front passenger to identify the user performing the touch operation. If the driver performs the corresponding touch operation, there is no need to implement personalized privacy protection controls. All control permissions of the screen mirroring application are granted, and content-level privacy protection controls are implemented. The content-level privacy protection controls are shown in the following example.

[0055] In some embodiments, after granting full control permissions, the method further includes: Blur sensitive information in screen mirroring applications; Change the layout of the screen mirroring application's interface; When a sensitive operation is detected by the target user, a pseudo interface corresponding to the screen mirroring application is displayed.

[0056] In practice, privacy protection controls at the content level include: Content filtering: Sensitive information is hidden or obscured. For example, WeChat messages only show notifications but hide the specific content; SMS verification codes are automatically blurred; and home and company addresses in navigation history are blocked. The system uses real-time content analysis technology to identify and filter various types of sensitive information and obscure them, including personal information, financial data, and security credentials.

[0057] Interface adjustments: Application interface layouts have been modified to protect privacy. For example, communication apps now only display the interface frame while hiding the actual conversation content, and photo streams in social media apps are blurred. The system can also adjust the screen display area to restrict sensitive information to specific areas that are less likely to be viewed by other passengers.

[0058] Input protection: When the system detects sensitive operations such as user inputting passwords, it can automatically turn off the projection screen temporarily or display a pseudo-interface to prevent the input process from being spied on.

[0059] It can also implement targeted content protection strategies based on application type and user settings: Communication apps (WeChat, SMS, phone): Highest level of content protection, automatically hides message previews, contact names and history, and only displays the location of the number instead of the specific number when receiving a call.

[0060] Navigation apps (map software): Moderate content protection, blocking detailed address records and home / company tags, while maintaining complete route guidance functionality.

[0061] Financial applications (banking, payment applications): Extremely sensitive content protection, automatically enables full-screen masking mode, and detailed information can only be displayed after identity verification on the host.

[0062] Media applications (music, video): Lowest level of content protection, usually no special measures are needed unless the user specifically sets to hide specific content (such as playlist names).

[0063] If the corresponding touch operation is performed by a front passenger, content-level privacy protection alone is insufficient. Personalized privacy controls, including application-level privacy controls, are required. For example, application-level privacy controls include: For highly sensitive applications in personalized configuration data (applications with the highest privacy protection level): the control strategy is to directly hide the application icon on the screen mirroring interface, so the front passenger cannot perceive the existence of such applications. This eliminates the possibility of the front passenger discovering, requesting to use, or accidentally operating highly sensitive applications, achieving absolute protection of core privacy. It avoids the embarrassment that the car owner may experience when refusing requests from relatives and friends to use the applications, reduces psychological concerns, and enhances the sense of privacy and security.

[0064] For moderately sensitive applications in personalized configuration data (applications with a medium privacy protection level): the control policy is to display the application icon normally, but keep it locked (no response when clicked). The car owner can proactively choose whether to unlock it based on their relationship with the passenger. This prevents unauthorized use while avoiding passenger confusion ("Why can't I see some applications?"). The car owner has flexible control over the scope of authorization. The car owner can politely avoid usage requests by citing reasons such as "system lag," achieving privacy protection without damaging interpersonal relationships and avoiding the awkwardness of direct refusal.

[0065] For low-sensitivity applications in the personalized configuration data (applications with the lowest privacy protection level): the control policy is to display the application icon normally and enable it by default, but specific functions (such as payment interfaces, history viewing, etc.) can be individually locked. While ensuring the availability of most functions, critical sub-functions that may involve privacy are restricted, achieving a fine balance between openness and protection. The front passenger can use basic functions without frequent intervention from the driver, ensuring both convenience and the safety of critical operations.

[0066] In some embodiments, the privacy protection method for vehicle-to-everything (V2X) connectivity further includes: In response to a change in passenger status from having a front passenger to not having a front passenger, exit privacy mode and remove all privacy protection controls.

[0067] In practice, the privacy protection control employs a dynamic adjustment mechanism. The protection strategy is not static but dynamically adjusted based on real-time changes in the in-vehicle passenger situation. For example, when the front passenger temporarily leaves their seat, the system can exit privacy protection mode and deactivate all privacy protection controls. This dynamic adjustment mechanism ensures the optimal balance between privacy protection and user experience, avoiding the inconvenience caused by over-protection.

[0068] In order to avoid directly controlling applications without going through the mobile device, the final privacy protection control data can be sent to the mobile device so that the mobile device can update the screen projection data based on the privacy protection control data, thereby realizing personalized privacy protection control at the application level.

[0069] In summary, the vehicle-to-everything (V2X) privacy protection method provided in this application has the following advantages: First, the highly personalized design allows car owners to customize their privacy preferences according to different applications and scenarios, ensuring that privacy protection meets individual needs. Second, the intelligent perception capability, through multi-sensor fusion technology, accurately determines the in-vehicle passenger situation, providing a reliable basis for privacy decisions. Third, the dynamic adjustment mechanism enables the system to adjust the activation and deactivation of protection controls based on real-time changes in in-vehicle passenger conditions, avoiding a decline in user experience due to over-protection. Finally, all processing is completed locally, avoiding the risk of sensitive data leakage.

[0070] In some embodiments, such as Figure 2 As shown, the privacy protection method for each screen mirroring application is determined based on the user's settings, including: Step 201: Follow the user's privacy settings to enter the privacy settings interface.

[0071] In practice, when car owners need to personalize the screen mirroring application, they can enter the privacy settings interface by clicking on specific display controls or buttons. In the privacy settings interface, each screen mirroring application is selectable.

[0072] Step 202: For the user's application selection operation in the privacy settings interface, display the privacy protection method selection interface corresponding to the selected screen mirroring application.

[0073] In practice, since each screen-casting application in the privacy settings interface is selectable, when the car owner selects an application in the privacy settings interface, a privacy protection method selection interface corresponding to the selected screen-casting application pops up. The privacy protection method selection interface includes "Advanced" display controls, "Medium" display controls, "Low" display controls, and "Cancel" display controls.

[0074] Step 203: Based on the user's priority selection operation on the privacy protection method selection interface, determine the privacy protection method of the selected screen mirroring application.

[0075] In practice, if the user clicks the "Advanced" display control in the privacy protection method selection interface, the selected screen-casting application's privacy protection level is set to the highest level. If the user clicks the "Medium" display control, the selected screen-casting application's privacy protection level is set to the medium level. If the user clicks the "Low" display control, the selected screen-casting application's privacy protection level is set to the lowest level. A pop-up window will then appear asking whether to restrict functionality. If the user needs to restrict functionality, they should click the "Yes" display control and then follow the pop-up functionality restriction selection interface to control the privacy protection of the selected functionality.

[0076] If the user clicks "Cancel" in the priority selection screen of the privacy protection method selection interface, the display control will return to the privacy settings interface, and after the settings are completed, the corresponding application will be set as the default protection level (e.g., medium protection level).

[0077] The highly personalized design allows car owners to customize their privacy preferences according to different applications and scenarios, ensuring that privacy protection meets individual needs.

[0078] In some embodiments, such as Figure 3 As shown, privacy protection controls for screen mirroring applications are implemented based on personalized configuration data and in-vehicle imaging, including: Step 301: In response to detecting an application touch operation in privacy protection mode, determine the identity of the user who performed the application touch operation based on the in-vehicle image.

[0079] In some embodiments, determining the identity of the user performing the application touch operation based on in-vehicle imaging includes: The location of the target user performing the application touch operation is determined by in-vehicle imaging. In response to the user's location being the primary driving position, the vehicle owner is identified as the user. In response to the user's location being the front passenger seat, the system matches the target user's features based on the passenger whitelist. In response to the presence of a target user in the passenger whitelist, the whitelisted passenger is identified as the user. If the target user is not found in the passenger whitelist, the ordinary passenger will be identified as the user.

[0080] In practice, the system uses in-vehicle imaging to determine the target user whose seating position is facing the in-vehicle central control screen, whose attention is directed towards the screen, and whose action is tapping the screen. The system then determines the target user's location based on the in-vehicle imaging. If the user is in the driver's seat, the user performing the application touch operation is the vehicle owner, and the owner is identified as the user; no application-level privacy protection is needed, only content-level privacy protection. If the user is in the front passenger seat, the user performing the application touch operation is the front passenger. A passenger whitelist is used to match the front passenger's features to determine if they require privacy protection. This whitelist can be pre-registered with the corresponding facial information of whitelisted users. If a matching facial image exists in the whitelist, the target user is confirmed to be in the whitelist, and no privacy protection is needed for the front passenger; they are identified as users. If no matching facial image exists in the whitelist, privacy protection is required for the front passenger, and they are identified as ordinary passengers.

[0081] Step 302: Implement privacy protection controls based on user identity and personalized configuration data.

[0082] In some embodiments, privacy protection controls are implemented based on user identity and personalized configuration data, including: When a user is identified as a vehicle owner or a whitelisted passenger, full control permissions are granted. In response to the user's identity as a regular passenger, privacy protection controls are implemented for the screen mirroring application based on personalized configuration data.

[0083] In practice, if the user is a car owner or a whitelisted passenger, there is no risk of privacy leakage, so all control permissions are granted, and no privacy protection is required. If the user is a regular passenger, there is a risk of privacy leakage, and privacy protection controls are applied to the screen mirroring application based on personalized configuration data. The specific process of privacy protection control is shown in the following example.

[0084] In some embodiments, such as Figure 4 As shown, privacy protection controls for screen mirroring applications are implemented based on personalized configuration data, including: Step 401: Determine the privacy protection method for each screen mirroring application based on the personalized configuration data.

[0085] In practice, personalized configuration data represents the privacy protection methods set by the car owner for each screen-casting application. By analyzing this personalized configuration data, the privacy protection level of each screen-casting application can be determined, and the corresponding privacy protection method can be determined based on the privacy protection level. Since the car owner does not want other users to use or see applications with the highest privacy protection level, all screen-casting applications with the highest privacy protection level are classified as highly sensitive applications, and their privacy protection method is to hide their application icons. Since the car owner does not want other users to use applications with the medium privacy protection level without authorization, all screen-casting applications with the medium privacy protection level are classified as moderately sensitive applications, and their privacy protection method is to display their application icons and disable responses to selection actions related to those icons. Since the car owner does not care if other users use screen-casting applications with the lowest privacy protection level, all screen-casting applications with the lowest privacy protection level are classified as low-sensitive applications, and their privacy protection method is to either fully open their usage permissions or restrict only some functions, thus achieving personalized privacy protection.

[0086] Step 402: Hide the first application icon of the first screen mirroring application. The first screen mirroring application is the screen mirroring application with the first privacy protection mode set to the first privacy protection mode.

[0087] In practice, for highly sensitive first screen-casting applications (applications with the highest level of privacy protection) in personalized configuration data: the first application icon of the first screen-casting application is directly hidden (not displayed during screen casting). This fundamentally solves the possibility that the front passenger might discover and use the first screen-casting application, achieving absolute protection for the first screen-casting application. Furthermore, since the front passenger cannot see the corresponding first application icon, they will not request the owner to grant the corresponding application permission, further reducing the owner's concerns (if the front passenger requests permission, not granting the corresponding permission may lead to a breakdown in the relationship between the owner and the front passenger, while granting the corresponding permission will leak some private data that the owner does not subjectively want to disclose), thereby improving the user experience.

[0088] Step 403: Display the second application icon of the second screen mirroring application and disable the response to selection operations on the second application icon. The second screen mirroring application is a screen mirroring application with the second privacy protection mode.

[0089] In specific implementation, for moderately sensitive second-screen projection applications (applications with a medium level of privacy protection) in the personalized configuration data: the icon of the moderately sensitive application will be displayed, but the icon of the second-screen projection application will be locked. That is, clicking the corresponding second-screen projection application icon will not respond to the corresponding touch operation, resulting in no response after clicking the second-screen projection application icon, in order to prevent passengers other than the car owner from using the second-screen projection application. The lock of the second-screen projection application can be actively unlocked by the car owner. For example, if the front passenger is a user with a close relationship with the car owner, the user can actively unlock the front passenger to grant the front passenger access; if the front passenger is a user with a distant relationship with the car owner, the user can not perform the unlock operation to prevent the front passenger from using the second-screen projection application. At this time, the user can find some excuses (such as system lag) to appease the front passenger, so as to protect the privacy information without damaging the relationship between the car owner and the front passenger (that is, when the car owner is embarrassed to refuse the front passenger, the privacy protection control can achieve automatic rejection control).

[0090] Step 404: Display the third application icon of the third screen mirroring application and disable the response to some functions of the third screen mirroring application. The third screen mirroring application is a screen mirroring application with the third privacy protection method.

[0091] In practice, for low-sensitivity third-party screen-casting applications (applications with the lowest level of privacy protection) in the personalized configuration data: the third-party application icon will be displayed, and the application icon will not be locked. Users can use the third-party screen-casting application. If the user has customized the third-party screen-casting application's functions, then the corresponding functions will be locked. If the user has not customized the third-party screen-casting application's functions, the front passenger can use all the functions of the third-party screen-casting application. The third-party screen-casting application uses a function restriction approach for targeted protection, ensuring personalized protection of key information while allowing open use, thereby improving the user experience.

[0092] By employing a three-tiered privacy protection control approach—visual isolation (hiding icons), interaction blocking (locking icons), and function blocking (restricting some functions)—privacy protection is integrated into the interaction design. This not only enhances security but also cleverly resolves the unique social privacy dilemma in in-vehicle screen projection scenarios.

The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task.
