Abstract

A change in state is identified of cargo that, at least for a time period, is carried by a vehicle. Spatiotemporal data indicative of a time and a place at which the change in state of the cargo occurs are assembled. The spatiotemporal data are recorded in a distributed electronic ledger. An occupant of the vehicle is alerted of the change in state of the cargo.
