Abstract: A system for securely tracking an entity aboard a vehicle includes a server situated at a first location and a verification system aboard the vehicle, which is configured to determine from an identification device of the entity a first identifier of the entity. The vehicle is at a second location different from the first location. A registration device aboard the vehicle includes a database. The registration device is coupled to the verification system and coupled over a network to the server. The registration device is configured to receive the first identifier from the verification system and determine from the database a second identifier of the entity corresponding to the received first identifier. The registration device is further configured to communicate the second identifier over the network to the server. The registration device does not communicate the first identifier over the network to the server.
