Abstract: The present invention provides an IoT data trading system including: a data transport unit capable of sending data to a predetermined counterparty; a data transaction unit that executes a trading contract of data; and an IoT device that provides IoT data, wherein the data transaction unit instructs, based on a buy offer of the IoT data issued from a predetermined account and a sell offer issued from an account of the IoT device, the data transport unit to send the IoT data from the IoT device to a data provider which owns the account from which the buy offer is issued, and imparts a monetary value of the sent IoT data to the account of the IoT device.

Abstract: This data transaction system is provided with: a data transport unit that is able to set a channel of data and deliver the data to a predetermined partner by control from outside; a data transaction unit that executes a transaction contract for the data; an acquisition unit that issues a selling offer of the data to the data transaction unit for the sake of a provider that provides the data; and a data broker that issues a buying offer of the data to the data transaction unit for the sake of a service provider that utilizes the data. The data transaction unit performs condition matching between the selling offer and the buying offer, and when both match, causes the data transport unit to set a channel for delivering the data from the data provider to the service provider.
