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: 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.
