[0069] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] Reference Figure 1 The diagram illustrates a flowchart of a data transmission method according to an embodiment of the present invention, applied to an in-vehicle device, and specifically includes the following steps:

[0071] Step 101: Receive the data transmission instruction for the target data.

[0072] In this embodiment of the invention, the in-vehicle device includes, but is not limited to, vehicle infotainment systems, dashcams, electronic devices mounted on other vehicles, or any other suitable in-vehicle device; this embodiment of the invention does not limit this. The mobile terminal includes, but is not limited to, mobile phones, tablets, laptops, or any other suitable mobile terminal; this embodiment of the invention does not limit this. A client that can communicate with the in-vehicle device runs on the mobile terminal. For example, an application corresponding to a smart vehicle running on a mobile phone.

[0073] In this embodiment of the invention, the target data can be data stored on the vehicle-mounted device, such as video, voice, and text.

[0074] For example, the data transmission command for a video recorded by a dashcam could be an instruction to transfer target data from the in-vehicle device to the mobile device. The target data could also be data stored on the mobile device. For instance, the data transmission command for a video stored on a mobile phone could be an instruction to transfer target data from the mobile device to the in-vehicle device.

[0075] In this embodiment of the invention, the vehicle-mounted device receives a data transmission instruction. For example, the video to be transmitted is selected on the screen of the vehicle-mounted device, and then the transmission button is clicked. Alternatively, the data transmission instruction may be a voice control instruction to transmit target data.

[0076] Step 102: Provide information encoding for the mobile device.

[0077] In this embodiment of the invention, information encoding is an encoding method that records information by distributing a specific graphic according to a certain rule. Specific forms may include QR codes, barcodes, etc. The provided information encoding can be displayed on a vehicle infotainment system or other electronic devices; there are no limitations on this. For example, when the in-vehicle device is a vehicle infotainment system, the information encoding can be displayed on the screen of the system or the screen of a dashcam.

[0078] In this embodiment of the invention, the information encoding includes relevant information required for data transmission between the vehicle-mounted device and the mobile terminal, so that the vehicle-mounted device and the mobile terminal can transmit target data based on the information encoding. For example, the information encoding can encode digitizable information such as vehicle identification information and network connection information.

[0079] The vehicle identification information refers to the information used to identify the vehicle. For example, each car has a unique VIN (vehicle identification number) code, which can be used as identification information, or any other applicable identification information. This embodiment of the invention does not limit this.

[0080] Network connection information refers to the information required to establish a network connection, such as Wi-Fi (Wireless Network Communication Technology) configuration information, DVR (Network Video Recorder) port information, protocol information, version information, etc. Specifically, it can include any applicable information, and this embodiment of the invention does not impose any limitations on it. Wi-Fi configuration information includes SSID (Service Set Identifier), password, encryption method, channel, etc., and DVR port information includes TCP Server (Transmission Control Protocol Server) port information. Protocol information refers to information related to the communication protocol. Version information refers to information indicating the version of the communication protocol.

[0081] Step 103: Based on the information encoding, transmit the target data with the mobile terminal.

[0082] In this embodiment of the invention, the vehicle-mounted device can transmit target data with the mobile terminal based on information encoding. Specific implementation methods can include various approaches, and this embodiment of the invention does not limit these methods.

[0083] For example, information encoding includes vehicle identification information, which can be used for identity authentication. After successful identity authentication, the in-vehicle device can transmit target data to the mobile terminal.

[0084] In an optional embodiment of the present invention, the information encoding includes network connection information. A specific implementation of transmitting target data with the mobile terminal based on the information encoding may include: establishing a transmission network connection for communicating with the mobile terminal based on the network connection information; and transmitting the target data with the mobile terminal based on the transmission network connection.

[0085] Information encoding includes network connection information. Based on the network connection information of the in-vehicle device, the mobile terminal can establish a transmission network connection, which refers to the network connection for communication with the in-vehicle device. For example, a TCP connection established between the vehicle's infotainment system and the mobile phone for file transfer. Establishing the transmission network connection includes determining the encryption method used when the mobile terminal communicates with the in-vehicle device. Based on this transmission network connection, the mobile terminal communicates with the in-vehicle device to transmit target data.

[0086] During communication between a mobile device and an in-vehicle device, when the in-vehicle device is a car infotainment system, the target data transmitted can be data related to any application or electronic device on the vehicle. This target data can be stored in the car infotainment system's storage unit, or it can be data stored in an application or other electronic device, and the data is transmitted between the car infotainment system and the mobile device. When the in-vehicle device is another electronic device, such as a dashcam, this electronic device can also have the capability to build a wireless local area network (WLAN) to communicate and transmit data with the mobile device; in this way, the electronic device can communicate independently with the mobile device to achieve data transmission.

[0087] In an optional embodiment of the present invention, a control network connection for controlling the transmission of target data in the transmission network connection can also be established based on the network connection information.

[0088] The control network connection is a separate network connection from the transport network connection. This control network connection is used to control the transmission of target data within the transport network connection. For example, the control network connection can be used to control the start, pause, and end of target data transmission (such as communication for a file transfer task). Dividing the network connection between the mobile device and the in-vehicle device into a transport network connection and a control network connection avoids the impact of control data transmission communication on data transmission within the transport network connection, thereby improving the data transmission speed within the transport network connection.

[0089] For example, information encoding includes vehicle and identification information and network connection information. Based on the network connection information of the in-vehicle device, the mobile device can establish a transmission network connection. Then, based on the account information and identification information on the mobile device, identity authentication is performed. After successful identity authentication, the in-vehicle device can transmit target data with the mobile device based on the transmission network connection.

[0090] According to embodiments of the present invention, by receiving a data transmission instruction for target data, information encoding is provided to the mobile terminal, and the target data is transmitted with the mobile terminal based on the information encoding. This enables convenient communication between the mobile terminal and the mobile terminal when data needs to be transmitted, based on the information encoding provided by the vehicle device. When it is necessary to export video from the vehicle device to the mobile terminal, the mobile terminal can easily obtain the video, thus improving the convenience of communication.

[0091] In an optional embodiment of the present invention, the information encoding includes vehicle identification information. A specific implementation of transmitting target data with the mobile terminal based on the information encoding may include: generating a communication key and sending a communication key encrypted using an in-vehicle device key to the mobile terminal, so that the mobile terminal can receive the communication key and decrypt it using the in-vehicle device key to obtain the communication key; wherein the mobile terminal pre-obtains the corresponding in-vehicle device key from the cloud based on the account information on the mobile terminal and the vehicle identification information; and uses the communication key to perform encrypted transmission of the target data with the mobile terminal.

[0092] Account information on a mobile device refers to the information of the account currently logged in on the client, such as the vehicle owner's account information or the account information authorized by the vehicle owner (such as the account information of the vehicle owner's family members). Account information includes, but is not limited to, account numbers, mobile phone numbers, etc., and this embodiment of the invention does not impose any restrictions on this.

[0093] The mobile device can send a request to the cloud for a key corresponding to the in-vehicle device based on account and identification information. Upon receiving the request, the cloud verifies the binding relationship between the account and identification information carried in the request. If the verification is successful, the cloud returns the in-vehicle device key corresponding to the identified identification information to the mobile device. The in-vehicle device key is the key corresponding to the in-vehicle device and is used for communication with it. The in-vehicle device also obtains this in-vehicle device key from the cloud for its own use. For example, after receiving the request, the cloud searches for the account and identification information carried in the request in its stored database of account and identification information binding relationships. If a matching binding relationship is found, the in-vehicle device key is returned; otherwise, it is not returned.

[0094] The mobile device sends a request for a communication key to the in-vehicle device. Upon receiving the request, the in-vehicle device generates a communication key for communication with the mobile device, encrypts the communication key using its own in-vehicle device key, and then sends the encrypted communication key to the mobile device. The mobile device decrypts the encrypted communication key using its own in-vehicle device key to obtain the actual communication key.

[0095] The in-vehicle device uses a communication key to conduct encrypted communication with the mobile device to transmit target data. Specifically, this can include the in-vehicle device encrypting the data to be sent using the communication key and then sending it to the mobile device, which can then decrypt the data using the communication key, or the mobile device encrypting the data to be sent using the communication key and then sending it to the in-vehicle device, which can then decrypt the data using the communication key.

[0096] For example, on the car's infotainment system, you select the video from the dashcam you want to export. The system uses a communication key to encrypt the selected video and then sends it to your phone. Your phone then uses the communication key to decrypt the video and retrieve it.

[0097] By generating a communication key and sending it to the mobile terminal, encrypted with the vehicle's onboard device key, the mobile terminal can receive and decrypt the communication key using the vehicle's onboard device key. The mobile terminal pre-obtains the corresponding vehicle's onboard device key from the cloud based on its account information and the vehicle's identification information. The target data is then encrypted and transmitted between the mobile terminal and the vehicle using this communication key. This ensures that if the account information and vehicle identification information on the mobile terminal are correct, the mobile terminal can obtain the vehicle's onboard device key, and thus the communication key from the vehicle's onboard device. This achieves secure and convenient communication between the mobile terminal and the vehicle's onboard device. When it is necessary to export video from the vehicle's onboard device to the mobile terminal, it securely and conveniently allows legitimate accounts to access the video, improving both the security and convenience of the communication.

[0098] In an optional embodiment of the present invention, before the encrypted transmission of the target data with the mobile terminal using the communication key, the method may further include: receiving a communication token encrypted using the communication key sent by the mobile terminal; decrypting the communication token using the communication key to obtain the communication token; verifying the communication token, and passing the verification.

[0099] Accordingly, the mobile terminal obtains the corresponding communication token from the cloud based on the account information and the identification information on the mobile terminal; the mobile terminal sends the communication token encrypted with the communication key to the vehicle device, so that the vehicle device can decrypt the communication token using the communication key, verify the communication token, and after the verification is successful, use the communication key to conduct encrypted communication with the mobile terminal.

[0100] Based on the account information and the identification information, the mobile device obtains not only the corresponding vehicle key from the cloud but also the corresponding communication token. This communication token is issued by the cloud for communication between the mobile device and the in-vehicle device. The mobile device can send a request for the communication token to the cloud based on the account information and identification information. Upon receiving the request, the cloud verifies the binding relationship between the account information and identification information carried in the request. If the verification is successful, the cloud returns the communication token to the mobile device. For example, after receiving the request, the cloud searches for the account information and identification information carried in the request in the cloud's stored binding relationship database. If a matching binding relationship is found, the communication token is returned; otherwise, no matching binding relationship is found, and the communication token is not returned.

[0101] The mobile device encrypts the communication token using a communication key and then sends the encrypted communication token to the in-vehicle device. Upon receiving the encrypted communication token, the in-vehicle device decrypts it using the communication key. The communication token is then verified, which can be performed by the issuer of the communication token. For example, the issuer can use their private key to verify the signature information in the communication token. If the verification passes, the verification is successful; otherwise, the verification fails. Any applicable verification method can be used, and this embodiment of the invention does not impose any limitations on this.

[0102] After successful verification, the in-vehicle device can use the communication key to conduct encrypted communication with the mobile terminal to transmit target data. For example, based on the aforementioned transmission network connection, the mobile terminal sends the communication token encrypted with the communication key to the in-vehicle device, and then the in-vehicle device uses the communication key to perform encrypted transmission of target data with the mobile terminal.

[0103] By verifying the communication token, security verification is achieved before valid data is transmitted between the mobile device and the in-vehicle device, thereby improving the security of encrypted communication between the mobile device and the in-vehicle device.

[0104] In an optional embodiment of the present invention, before providing information encoding to the mobile terminal, the method may further include: activating a wireless network access point; the transmission network connection is established through the wireless network access point.

[0105] A wireless network access point refers to a function such as a Wi-Fi hotspot that connects via a wireless network. It's the hardware that establishes a transmission network connection between a mobile device and an in-vehicle device. For example, enabling a hotspot function on a vehicle's infotainment system requires configuring compliant channels and bandwidth according to radio regulations. A wireless network access point can automatically activate upon receiving a data transmission command, or it can be manually activated, or it can activate after the in-vehicle device starts up and remain active thereafter.

[0106] In an optional embodiment of the present invention, the network connection information includes information required to establish a network connection based on the transmission control protocol, wherein the transmission network connection is a network connection based on the transmission control protocol.

[0107] Network connection information includes the information required to establish a network connection based on the Transmission Control Protocol (TCP). This includes, for example, Wi-Fi configuration information, DVR port information, protocol information, and version information. Based on this network connection information, a TCP connection can then be established between the mobile device and the in-vehicle infotainment system.

[0108] Reference Figure 2The diagram illustrates a flowchart of a data transmission method according to an embodiment of the present invention, applied to a mobile device, and specifically includes the following steps:

[0109] Step 201: Identify the information code provided by the vehicle-mounted equipment.

[0110] In this embodiment of the invention, the mobile device can identify the information encoding provided by the in-vehicle device and obtain the data of the information encoding. For example, scanning a QR code obtains the QR code data.

[0111] Step 202: Based on the information encoding, transmit the target data with the vehicle-mounted device.

[0112] In this embodiment of the invention, the specific implementation of this step can be found in the description of the foregoing embodiments, and will not be repeated here.

[0113] In an optional embodiment of the present invention, the information encoding is parsed to obtain vehicle identification information and network connection information.

[0114] The in-vehicle device provides an information code that includes vehicle identification information and network connectivity information. The mobile device scans this information code and then parses it to obtain the vehicle identification information and network connectivity information.

[0115] By scanning information encoding, the convenience of mobile devices obtaining vehicle identification and network connection information is improved, thereby enhancing the convenience of communication between mobile devices and vehicles.

[0116] In one optional embodiment of the present invention, a specific implementation of parsing the information encoding to obtain vehicle identification information and network connection information may include: parsing the information encoding to obtain encrypted information; and decrypting the encrypted information to obtain the identification information and the network connection information.

[0117] The vehicle identification and network connection information in the encoded information can be encrypted. Parsing the encoded information yields the encrypted information. Decrypting this encrypted information is then necessary to retrieve the identification and network connection information. The encryption password can be a default password—one accessible to both the mobile device and the vehicle. For example, both the vehicle's infotainment system and the mobile client may have pre-stored default passwords. To prevent vehicle information leakage, an Initialization Vector (IV) is used to encrypt each piece of information.

[0118] By encrypting the identification information and network connection information, the confidentiality of the identification information and network connection information is achieved, thereby improving the security of the mobile terminal obtaining the in-vehicle device key and establishing a transmission network connection.

[0119] According to embodiments of the present invention, by identifying the information code provided by the vehicle-mounted device, and based on the information code, target data is transmitted with the vehicle-mounted device. This enables convenient communication between the vehicle-mounted device and the mobile terminal when data needs to be transmitted, based on the information code provided by the vehicle-mounted device. When it is necessary to export video from the vehicle-mounted device to the mobile terminal, the mobile terminal can easily obtain the video, thus improving the convenience of communication.

[0120] In an optional embodiment of the present invention, the information encoding includes vehicle identification information. The transmission of target data with the in-vehicle device based on the information encoding includes: obtaining the vehicle identification information based on the information encoding; sending the account information and the identification information from the mobile terminal to the cloud; receiving the in-vehicle device key returned by the cloud after the cloud verifies the account information and the identification information; decrypting the encrypted communication key sent by the in-vehicle device using the in-vehicle device key to obtain a communication key; and using the communication key to perform encrypted transmission of the target data with the in-vehicle device. For details, please refer to the description in the foregoing embodiments; further elaboration is not provided here.

[0121] In an optional embodiment of the present invention, before using the communication key to perform encrypted transmission of the target data with the vehicle-mounted device, the method may further include: obtaining a corresponding communication token from the cloud based on the account information and the identification information on the mobile terminal; sending the communication token encrypted with the communication key to the vehicle-mounted device, so that the vehicle-mounted device can decrypt the communication token using the communication key, verify the communication token, and, upon successful verification, use the communication key to perform encrypted transmission of the target data with the mobile terminal. For details, please refer to the description in the foregoing embodiments; further elaboration is not provided here.

[0122] In an optional embodiment of the present invention, a specific implementation of using the communication key to perform encrypted transmission of target data with the vehicle-mounted device may include: receiving a sensitive file encrypted using the communication key sent by the vehicle-mounted device; and decrypting the sensitive file using the communication key.

[0123] Sensitive files refer to files with high security or privacy requirements, such as dashcam videos, photos or videos taken by in-vehicle cameras, or other files that can be used in any way. This embodiment of the invention does not impose any restrictions on this.

[0124] The in-vehicle device uses a communication key to encrypt sensitive files, and then sends the encrypted sensitive files to the mobile device. After receiving the encrypted sensitive files, the mobile device uses the communication key to decrypt them and obtain the sensitive files.

[0125] Encrypted communication between in-vehicle devices and mobile terminals is used to transmit sensitive files, which improves the security of sensitive file transmission.

[0126] To enable those skilled in the art to better understand this application, the following specific examples illustrate one implementation of this application.

[0127] like Figure 3 The diagram shown illustrates the process of securely transmitting data between a mobile phone and a vehicle's infotainment system, which may include the following steps.

[0128] Step 1: The user clicks "DVR Export," which means clicking "Export Video from DVR."

[0129] Step 2: The HU (vehicle infotainment system) provides a QR code, which includes the vehicle's VIN code and may also include network connection information.

[0130] Step 3: Use the APP Phone (mobile application) to scan the QR code, then parse it to obtain the vehicle's VIN code. The mobile application can verify the binding relationship between the currently logged-in account information and the VIN code. If the verification is successful, you can continue to the next steps.

[0131] Step 4: The mobile app requests an access token (communication token) from IDAAS (Identity as a Service). IDAAS sends the account information and identification information from the request to the account system, which verifies the relationship between the person and the vehicle and sends the verification result back to IDAAS. After receiving the successful verification, IDAAS returns the access token to the mobile app. In other words, the mobile device obtains the communication token from the cloud.

[0132] Step 5: The mobile app requests the vehicle key (e.g., a public key based on the 25519 algorithm) corresponding to the account information and VIN code from the account system. The account system verifies the vehicle-to-person relationship based on the account information and the identification information, i.e., verifies the binding relationship between the account information and the identification information. After successful verification, the system obtains the vehicle key from the key system and then returns the vehicle key to the mobile app. In other words, the mobile device obtains the vehicle key from the cloud.

[0133] Step 6: The APP phone and HU connect via WiFi and establish a TCP connection.

[0134] Step 7: The APP phone sends an SK key request to the HU. This request can be sent in plaintext or encrypted using the vehicle's in-vehicle key mentioned above.
