The chat room generation unit 108 may generate the chat room so that the seller terminal 200 and the buyer terminal 300 can chat with each other. Specifically, the chat room generation unit 108 can generate a group chat room with the seller terminal 200 matched with the seller of two or more sales articles selected by the purchaser from the sales list.

3 (a), the chat room generation unit 108 generates a check box (not shown) of a selling article of interest (that is, the interested goods) among the sales list 302 through the purchaser terminal 300 304, and then selects the chat room creation button 306 to receive the chat room creation request signal.

3B, the chat room generating unit 108 receives the chat room generation request signal from the buyer terminal 300, and transmits the chat room generation request signal to the buyer terminal 300 and the selected plurality of the seller terminals 200, A group chat room can be created. At this time, the buyer can lower the price of the used goods to be purchased through reverse chatting through group chat with the sellers.

3 (c), when the chat room generation unit 108 generates a group chat room between the buyer terminal 300 and a plurality of the seller terminals 200, the list provider 106 described above, Can blind the sales letters of the sellers participating in the group chat room. Thereafter, when the group chat room is terminated, the sales text of the seller who is not selected as the used goods transaction is canceled and the blind processing can be confirmed on the sales list.

The chat room generation unit 108 may generate the chat room so that the seller terminal 200 and the purchaser terminal 300 can perform one-to-one chat. Specifically, when the buyer selects a seller who wants to perform a transaction in the group chat room through the purchaser terminal 300, the chat room generation unit 108 generates a one-to-one chat room so that one-on-one chat with the seller terminal 200 of the seller Can be generated.

Through this, the buyer can lower the price of the used goods to be purchased by talking with a large number of sellers, and the seller can select the seller based on the lowered price, thereby enabling the one-on-one chatting.

The transaction contract management unit 110 can create a used transaction contract between the buyer and the seller. Specifically, when the transaction contract management unit 110 receives a used transaction agreement request signal in the one-to-one chat room between the buyer terminal 300 and the seller terminal 200, the transaction contract management unit 110 can create a used transaction agreement. At this time, the used-trade contract is a contract for selling the used-goods information (for example, a used-article photograph, a transaction method, a used-article-made content, etc.) that the seller has uploaded through the seller terminal 200 and the seller and the buyer via a group chat room and a one- Can be created based on negotiated transaction prices.

Referring to FIG. 4A, the transaction contract management unit 110 may receive an agreement signal from the buyer terminal 300 and the seller terminal 200 for each item started in the used transaction contract. For example, the transaction contract management unit 110 determines whether the used goods transaction method is a courier transaction or not, whether each of the purchaser terminal 300 and the seller terminal 200 has been informed of the deficiency of the used goods in the used- It is possible to receive an agreement signal for each.

Referring to FIG. 4 (b), the transaction contract management unit 110 may generate a used transaction establishment contract upon receiving the agreement signal for the used transaction agreement. Specifically, when the transaction contract management unit 110 receives the agreement signal from the buyer terminal 300 and the seller terminal 200 for each item described in the transaction contract, the transaction contract management unit 110 can create a used transaction establishment contract based on the agreement signal. At this time, the transaction contract management unit 110 can perform digital signature based on the authentication information of the buyer and the seller in the used transaction establishment contract.

Through this, it becomes possible to agree on the exchange, refund, and fraud that occurs in the secondary transaction as described in the contract.

The advertisement management unit 112 may provide advertisements to the buyer terminal 300 and the seller terminal 200. [ Specifically, when the transaction management unit 110 receives the agreement signal from the buyer terminal 300 and the seller terminal 200, the advertisement management unit 112 notifies the buyer terminal 300 and the seller terminal 200, The advertiser 200 can provide the advertisement.

The database unit 114 may store various types of information used in the used transaction management server 100. [ Specifically, the database unit 114 may match the seller terminal 200 and the purchaser terminal 300 to store the authentication information of the seller and the purchaser. In addition, when the used merchandise transaction is made, the merchant terminal 200 and the purchaser terminal 300 may be matched with each other to store the used transaction establishment contract. In addition, an advertisement provided to the seller terminal 200 and the buyer terminal 300 may be stored.

Here, the typical example stored in the database unit 114 is described, but the present invention is not limited thereto. The database unit 114 can store all information that can be stored in the used transaction management server 100 to be.

5 is a flowchart of an online used goods transaction method according to an embodiment of the present invention.

Referring to FIG. 5, the used goods transaction server 100 receives the goods of interest from the buyer terminal 300 (S502). Specifically, the used goods transaction server 100 checks the check box 304 of the selling article of interest (that is, the item of interest) in the sales list 302 through the purchaser terminal 300, Request signal.

Next, the used goods transaction server 100 creates a group chat room (S504). Specifically, the used goods transaction server 100 can generate a group chat room between the seller of the goods of interest and the buyer in response to the chat room creation request signal received from the purchaser terminal 300.

Next, the used goods transaction server 100 receives the one-to-one chat room creation request signal (S506). Specifically, the used goods transaction server 100 can generate a one-to-one chat room by receiving a one-to-one chat room creation request signal from the purchaser terminal 300. At this time, the one-to-one chat room may be a chat with one of the sellers participating in the group chat room. If the one-to-one chat room is created, the used-goods transaction server 100 deletes the existing group chat room and generates a one-to-one chat room.

Next, the used commodity trading server 100 confirms whether or not the used trading contract request signal is received (S508). Specifically, the used goods transaction server 100 can confirm whether the buyer and the seller who participated in the one-to-one chat room transmit the used transaction agreement request signal through the inputs of the buyer terminal 300 and the seller terminal 200, respectively. If the user terminal 300 and the seller terminal 200 do not receive the used transaction agreement request signal, the used goods transaction server 100 does not proceed to the next step.

Next, the used commodity trading server 100 confirms whether a consent signal is received (S510). Specifically, the used-goods transaction server 100 determines whether or not each of the buyer and seller who has transmitted the used-trade-agreement request agrees with each item of the used-trade contract through the input of the buyer terminal 300 and the seller terminal 200 .

Next, the used goods transaction server 100 creates a used transaction establishment contract (S512). Specifically, the used goods transaction server 100 can generate a used transaction establishment contract upon receiving a consent signal to agree with each item of the used transaction agreement from the buyer terminal 300 and the seller terminal 200. At this time, the used commodity trading server 100 can perform digital signature based on the authentication information of the buyer and the seller in the used transaction establishment contract.
