An example operation includes one or more of saving a hash of data including occupant data and transport data on a transport in response to the transport is started, performing a security check that validates the hash of data against the data in response to the transport is started, and providing a resolution when the security check fails.

An in-vehicle speech interaction method and a device are provided. The method includes: obtaining user speech information; determining a user instruction based on the user speech information; determining, based on the user instruction, whether response content to the user instruction is privacy-related; and determining, based on whether the response content is privacy-related, whether to output the response content in a privacy protection mode, to protect privacy from being leaked.

A method for data processing is performed by an operation data recording device. The method includes: in response to a data access request sent by a client for a target vehicle, generating symmetric keys for symmetrically encrypting operation data of the target vehicle, in which the symmetric keys are generated based on a user ID and a primary public key for a third party, and the user ID is carried in the data access request; obtaining target encrypted data by symmetrically encrypting the operation data using the symmetric keys; and sending the target encrypted data to the client.

A method is disclosed for authentic data transmission between control devices of a vehicle in which messages which are sent from a first control device to a receiver control device and are provided with a first cryptographic key for authentication, and messages that are sent from a second control device to the receiver control device are provided with a second cryptographic key for authentication. First status information provided with a third cryptographic key is sent from a monitoring module of the first control device to the receiver control device and second status information provided with the second cryptographic key is sent from the second control device to the receiver control device. The first status information and second status information are received by the receiver control device. The received first and second status information is evaluated to detect a manipulation of the first control device.

A vehicle control device is provided. The vehicle control device includes a terminal device authentication unit that determines whether a terminal device of a user registered as a user of a vehicle, in advance, is present around or within the vehicle. The vehicle control device also includes a communication unit that communicates with the terminal device. Also included in the vehicle control device is a control unit that causes a display device provided in the vehicle to output a screen for setting communication between the communication unit and the terminal device. The display device outputs the screen in a case where it is determined by the terminal device authentication unit that the terminal device is present and the display device is started up.

Systems and methods are disclosed with respect to using a blockchain for managing the subrogation claim process related to a vehicle accident, in particular, determining fault as part of the subrogation process. An exemplary embodiment may include receiving an electronic notification of a vehicle collision; receiving sensor data (such as telematics, image, audio, vehicle operational, or other sensor data) related to the vehicle collision; determining a percentage of fault of the vehicle collision for one or more vehicles, vehicle systems, and/or drivers based upon, at least in part, analysis of the sensor data collected; and creating a blockchain for the vehicle collision with one or more links to the sensor image data and an indication of the percentage of fault(s) determined to facilitate blockchain-based claim handling.

A vehicle information communication system includes a center apparatus and a vehicle apparatus that includes a group of electronic control units (ECUs) and that sends vehicle configuration information including configuration information on the group of ECUs mounted in the vehicle to the center apparatus via wireless communications. The center apparatus performs a first determination of whether the vehicle configuration information received from the vehicle apparatus matches approved-configuration information registered in an approved-configuration database, and performs a second determination of whether software update data for at least one ECU of the group of ECUs mounted in the vehicle exists in an update database. When both the first and second determinations are true, the center apparatus sends the software update data for at least one ECU of the group of ECUs mounted in the vehicle to the vehicle apparatus via the wireless communications.

A method for data exchange on a communication network, operating according to a protocol, and including a transmission bus, a first node and a second node. The first node carries out the steps of: constructing a first and a second data frame which transport first and second information data; calculating a first message authentication code as a function of the first and the second information data; constructing a third data frame which transports the first message authentication code; transmitting all of the data frames thus constructed. The second node carries out the steps of: receiving the first, the second and the third data frames; extracting the first and the second information data and the first message authentication code; calculating a second message authentication code as a function of the first and the second information data extracted; comparing the message authentication code extracted with the message authentication code calculated in order to verify the identity thereof.

A terminal device verification method and an apparatus are provided. The method includes: A first network device receives a first message from a first terminal device. Then, the first network device verifies a pairing relationship between the first terminal device and a second terminal device. After the verification on the pairing relationship between the first terminal device and the second terminal device succeeds, the first network device sends a second message to the first terminal device, where the second message include first indication information, and the first indication information is used to indicate a pairing result of the first terminal device and the second terminal device. The pairing relationship between the first terminal device and the second terminal device is verified, so that the first terminal device and the second terminal device can be securely paired, to improve use security of the first terminal device and the second terminal device.

A vehicle identifier and a nonfungible token (NFT) associated with the vehicle identifier are stored on an electronic ledger. The electronic ledger is a distributed electronic ledger shared between at least a computer and a remote computer. Upon transitioning a vehicle to an on state, the electronic ledger is queried to identify programming instructions associated with the NFT. Upon retrieving the identified programming instructions from the electronic ledger, the vehicle is actuated based on the retrieved programming instructions.
