Abstract: A server includes a unit obtaining a position of a registered vehicle, a unit obtaining a vehicle dispatch position, a unit determining a candidate vehicle based on the vehicle dispatch position and the position of the registered vehicle, a unit transmitting information regarding an autonomous driving function of the candidate vehicle to a user device, a unit receiving information for identifying a dispatch vehicle, and a unit transmitting a vehicle dispatch position to the dispatch vehicle. The user device includes a unit receiving the information regarding the autonomous driving function of the candidate vehicle, a unit displaying the information regarding the autonomous driving function of the candidate vehicle, an unit accepting a user operation for selecting the dispatch vehicle, and a unit transmitting the information for identifying the dispatch vehicle to the server.

Abstract: An authentication code detecting unit detects data addition authentication information from a print job. An upper apparatus specifying unit specifies a transmitting source of the print job. A RAM stores the data addition authentication information, the transmitting source of the print job, and the print job. An operating unit receives print request authentication information. An elapsed time measuring unit measures an elapsed time from the reception of the print job having the data addition authentication information. An erasure extension necessity inquiry unit requests an answer about the necessity of extension of an erasing time from the transmitting source when the measurement result indicates the elapse of a predetermined time. When the erasure extension is necessary, an erasure/extension decision processing unit extends the elapsed time until the erasure of the print job after its reception.
