Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a process may include determining a potential position overlap between a first vehicle and a second vehicle and determining a characteristic of at least one of the first vehicle or the second vehicle based on information from a vehicle-based message. The process may include determining whether the potential position overlap is an actual position overlap between the first vehicle and the second vehicle based on the characteristic.

Abstract: A method for managing a plurality of imaging devices in a vehicle includes determining that a change of data security mode is indicated for frames of image data transmitted over a first data communication link, determining whether a sensor management system has sufficient processing capacity to support the change of data security mode, increasing the processing capacity of the sensor management system by modifying data security settings for at least one other data communication link when the processing capacity of the sensor management system is insufficient to support the change of data security mode, and initiating the change of data security mode when the sensor management system has sufficient processing capacity to support the change of data security mode. The change of data security mode may include a change from an application-based to a link-based data security mode or a change from the link-based to the application-based data security mode.

Abstract: Systems and techniques are described for token device transfer management. A system identifies, in a payload of at least one block of a distributed ledger, a token corresponding to media content. A parameter of the token in the distributed ledger indicates that the token is associated with a first user. The system identifies a device that is associated with the token and the media content. The device is also associated with the first user. The system identifies that the device has been relocated to an area associated with a second user. In response to identifying that the device has been relocated to the area, the system causes the parameter of the token in the distributed ledger to be modified from indicating that the token is associated with the first user to indicating that the token is associated with the second user.

Abstract: Embodiments include methods performed by a vehicle-to-everything (V2X) system for protecting proprietary data within misbehavior reports. The method includes receiving a misbehavior report from a V2X system participant, obtaining sensor data from the received misbehavior report indicating that a misbehavior condition has occurred, determining whether the sensor data indicating that a misbehavior condition has occurred includes encrypted proprietary information. In response to determining that the sensor data includes encrypted proprietary information, the V2X system identifies an entity that owns the encrypted proprietary information, transmits the misbehavior report including the encrypted proprietary information to the entity that owns the encrypted proprietary information, and receives a confirmation report from the entity that owns the encrypted proprietary information indicating whether the misbehavior report is accurate.

Abstract: Systems and techniques are described for situational token-associated media output. A system receives sensor data captured by at least one sensor of a media device. The system identifies, based on the sensor data, a relationship between the media device and an anchor element that is associated with a token. The system identifies the token in a payload of at least one block of a distributed ledger. The token corresponds to media content according to the distributed ledger. The system generates a representation of the media content corresponding to the token. In response to identifying the relationship between the media device and the anchor element, the system outputs the representation of the media content.

Abstract: Methods, systems, and devices for road usage charging (RUC) are described. RUC computation may be performed at a vehicle using a vehicle computing device (VCD) that is trusted by a service provider, charger, or both. The VCD may be trusted to collect high accuracy, high resolution time and location data for RUC, and also compute for itself what the RUC charge is according to one or more applicable charge policies that are provided to the VCD. Anonymity related to specific vehicle and location information may be provided by encrypting portions of RUC data that are decryptable by different entities with reduced likelihood of revealing specific vehicle, location, and time information.

Abstract: A processing circuit is coupled to imaging devices through multiple data communication links. Each data communication link couples at least one imaging device with the processing circuit. The processing circuit is configured to determine when a change is required in a first data protection configuration that protects first image data transmitted over a first data communication link, and determine a second data protection configuration to be used when second image data is transmitted from a first imaging device over the first data communication link to an image processing circuit. The first data protection configuration or the second data protection configuration provides a partial integrity mode of data protection for frames of image data transmitted over the first data communication link. The partial integrity mode protects some, but not all frames of image data transmitted over the first data communication link using a message authentication code.
