Abstract

A method, a device for performing the method, and a recording medium are disclosed, comprising: a step of obtaining receipt information including transaction history information regarding a transaction target corresponding to a cost payment as a cost payment corresponding to a user account occurs; a step of providing a receipt NFT (Non-Fungible Token) corresponding to the receipt information to the user account based on the transaction history information; a step of determining whether to approve authentication for the transaction target based on the transaction history information as the possession of the receipt NFT by the user account is confirmed; and a step of providing an authentication approval message to a buyer account requesting authentication for the transaction target as authentication for the transaction target is approved.

Description

Method and device supporting transaction target authentication using receipt NFT The technical field of the present disclosure relates to a method and device that support authentication of a transaction target using a receipt NFT, and more specifically, to a technical field that provides a system and method of use for performing authentication of a transaction target for which a transaction has been performed according to a payment method corresponding to a user account. Traditionally, beyond the trading of new goods both online and offline, the trading of used goods has become active, utilizing methods such as card payments and bank transfers via smartphones. Generally, accounts wishing to sell (transfer) used goods upload information about the items to websites or applications installed on mobile devices, and the system operates in a manner where the trading of uploaded items proceeds actively. Furthermore, in this type of used goods trading, transactions are conducted through a method where the transferor and transferee accounts mutually negotiate the price. However, according to current general used goods trading systems, unless a direct transaction is conducted, the condition of a used item can only be verified and predicted based solely on the sales information provided by the transferor account, without actually inspecting the item. Consequently, cases where transferor accounts falsely or ambiguously enter information about used goods frequently occur, resulting in victims of fraudulent transactions. In particular, for luxury goods, authenticity plays a crucial role in determining the price, so clarity regarding this is essential. Therefore, in the execution of second-hand transactions, there is a need for a method and system that enables the provision of safe transaction services by offering a reliability-based authentication method for second-hand goods.
