  • Patent number: 11218309
    Abstract: An onboard device transfers an encrypted message encrypted outside a vehicle to one or more vehicle controllers connected to a vehicle network. When the encrypted message is an individual message to one of the vehicle controllers, the onboard device transmits the encrypted message to the one of the vehicle controllers via the vehicle network. When the encrypted message is a common message to the one or more vehicle controllers, the onboard device decrypts the encrypted message using an encryption key owned by the onboard device and then transmits the decrypted message to the one or more vehicle controllers via the vehicle network.

  • Patent number: 11218456
    Abstract: A vehicle-oriented service providing system includes an in-vehicle device and configured to receive commands applied to a control device inside the vehicle, a vehicle information server configured to transmit the commands to the in-vehicle device, and a push information server configured to mediate the transmission of the commands from the vehicle information server to the in-vehicle device. In the commands, a security level prescribed in advance for each of the commands is set. The vehicle information server performs encryption corresponding to the security level on the commands, and requests the push information server for transmission. The in-vehicle device is configured to wait for commands from the push information server. The in-vehicle device is configured to decrypt the received encrypted commands, and solely when encryption corresponding to a security level equal to or higher than the security level set in advance in the commands is performed, execute the commands.

  • Patent number: 11070769
    Abstract: A collaborative security camera system includes a primary vehicle including a sensor to obtain data related to an object, and a first controller. The first controller classifies the object as suspicious activity or non-suspicious activity based on the obtained object data, determines a moving path of the object in response to the object being classified as suspicious activity, and broadcasts a signal including the moving path of the object if the object is classified as suspicious activity. The collaborative security camera system also includes a secondary vehicle including a sensor configured to obtain image data related to the object, and a second controller. The second controller receives the broadcasted signal, determines if the secondary vehicle is within the moving path, and captures image data of the object if the secondary vehicle is proximate the moving path.
