PROBLEM TO BE SOLVED: To provide a "data identification management device and a data identification management method" designed to enable a plurality of pieces of data sent from a plurality of portable terminals connected to an on-board apparatus to be identified by the on-board apparatus to determine which portable terminal the data has been sent from.SOLUTION: The data identification management device comprises a terminal identification information imparting unit 12 which, when a data receiving unit 11 receives a plurality of pieces of place data from a plurality of portable terminals 20and 20, imparts a terminal ID received together with the place data to each of the plurality of pieces of place data, and causes a data storage unit 13 to store the plurality of pieces of place data with the terminal ID being imparted thereto. By managing the plurality of pieces of place data received from the plurality of portable terminals 20and 20by imparting a terminal ID individually to the plurality of pieces of place data, it is made possible for an on-board device 10 to identify the plurality of pieces of received place data to find which of the portable terminals 20and 20each piece of the data has been sent from. |
