  A transaction management system according to an aspect of the present disclosure is a transaction management system that manages transactions for exchanging articles between a first person and a second person, and is attached to the article and is electronically processed A first key which is opened and closed by a key and which can be removed after unlocking, and an article storage provided with a second key which is opened and closed by electronic processing, wherein the article is physically An article storage that can be stored, and a key management unit that manages a first key unlocking right that can open and close the first key and a second key unlocking right that can open and close the second key A transaction management unit for managing transactions relating to the article, wherein the key management unit performs management for registering that the first key unlocking right and the second key unlocking right belong to the first person The first person is attached to the article storage by Opening the second key and taking out the article from the article storage, and making it possible to open the first key attached to the article and remove the first key from the article, the transaction management And the part is configured to temporarily store the article from the second person when the second key of the article storage in which the article is stored is acquired from the article storage. A second transaction that the first person truly receives the item after reviewing that the first transaction received is managed from the first key when it is obtained that the first key has been opened Manage as if

  According to this configuration, the first person who receives the item receives the inappropriate item by using the opening / closing history of the first key and the second key opened and closed by electronic processing as the transaction history of the delivery of the item. Can be deterred. Also, even if the first person has received an inappropriate item, the transaction history of the delivery of the item is surely left as electronic evidence, so the second person who has given the item can receive it. It is possible to appropriately carry out return processing or exchange processing etc. That is, according to this configuration, it is possible to more reliably carry out the transaction of the exchange of the appropriate articles without facing each other. As a result, it is possible to suppress disguising of goods or disguising of dealings, so that energy saving such as reduction of goods used for disguising itself or reduction of energy consumption for return or exchange processing etc. can be achieved. Can.

  Here, for example, the history of opening and closing of the first key and the history of opening and closing of the second key are recorded in the ledger by the transaction management unit or the key management unit, and the transaction management unit stores the article. The first transaction is established when it is obtained from the item storage that the second key of the item storage is opened and it is recorded in the ledger that the second key is opened. The management is performed, and when the fact that the first key has been opened is recorded in the ledger, the second transaction is managed as being established.

  Also, for example, the ledger is a distributed ledger in which a plurality of ledgers having the same contents are built on the basis of a block chain, and the key management unit determines the first key unlocking right and the second key unlocking. The first key unlocking right and the second key unlocking right may be managed by accumulating registration of rights as a history.

  In addition, for example, it further has a key destruction detection unit that detects whether or not the first key is destroyed, and the transaction management unit acquires that the first key is destroyed from the key destruction detection unit. When the fact that the first key has been opened is recorded in the ledger, it may be managed as the establishment of the second transaction.

  Also, for example, when the item is not truly received by the first person after being examined by the first person after the first transaction, the article is returned to the second person, and the transaction is performed. After the managing section manages that the first transaction has been established, the second key can not be opened, and the second item can not be returned to the second person if a predetermined period has passed. It may be managed as the transaction is concluded.

  Also, for example, the first key may be in the form of a tag, and may be attached to the article by being bound to the article.

  Also, for example, after the transaction management unit manages that the first transaction has been established, the first key can not be opened, and the article is physically stored in the article storage, and the second When the key is closed, the second transaction may be managed as not being established.

  Also, for example, the article storage further includes an RFID reader, and the first key or the article is further attached with an RFID indicating the article, and the transaction management unit determines the first transaction. After managing that the item has been established, the item storage device reads the RFID with the RFID reader to confirm that the item has been physically stored in the item storage, and the second key The closing may be acquired from the item storage, and when the first key is not opened, the second transaction may be managed as not being established.

  Also, for example, the first person is a buyer, the second person is a seller, and the item is a product provided by the second person, and a transaction for temporarily receiving the item Is a transaction for confirming whether the item is an item desired by the first person before deciding to purchase the item, and a transaction that truly receives the item determines the item to be purchased It may be a trade that has been made.

  Also, for example, the deposit management unit further includes a deposit management unit for temporarily depositing the payment by the buyer's electromagnetic method, and the deposit management unit manages that the second transaction has been established by the transaction management unit. If it is determined that the payment is transferred to the seller, and if it is managed by the transaction management unit that the second transaction has not been established, the payment may be returned to the buyer. Good.

[Operation etc. of the transaction management system 1]
The operation of the transaction management system 1 configured as described above will be described below.

  FIG. 10 is a diagram for conceptually explaining the operation of the transaction management system 1 in the present embodiment. FIG. 11 is a diagram showing the transaction user, the unlocking right, the unlocking history and the like in the situation shown in FIG. In FIGS. 10 and 11, the case where the second person sends the article 50 to the first person and the first person receives it is shown. In the following, it is described that the article 50 is the electronic device A, and the article storage 3 is one delivery box within a distance that the first person can receive. Note that FIG. 11 shows the case where the identifier of the first key 4 is recorded in the ledger 211 as article identification information which is information for identifying the article 50.

  First, when the second person arranges to deliver the article 50 with the first person, the second person performs the shipping process of the article 50. More specifically, the second person who is the owner of the article 50 attaches the first key 4 to the article 50, which is the electronic device A, as shown in (a) of FIG. Then, the second person uses the transaction management system 1 to make a transaction for shipping the goods in such a manner as to have the contents shown in the situation 1 of FIG. 11 corresponding to (a) of FIG. That is, the transaction user is the second person, the item information of the item 50 is the electronic device A, the item identification information is the identifier of the first key 4, and the first key unlocking right is the first person, (2) Conduct a transaction to register the key unlocking right to be the second person or the delivery company. Also, the second party uses the transaction management system 1 to perform a transaction to close the first key 4 attached to the article 50. When the second party prepares to ship the article 50, the second party uses the transaction management system 1 to conduct a transaction to carry out a procedure to ship the article 50.

  In the situation 1 of FIG. 11, the second person only closes the first key 4 attached to the article 50 for the delivery processing of the article 50, and does not open the first key 4. There is no key unlocking history. Further, since the article 50 to which the first key 4 is attached is at the hand of the second person and is before being stored in the article storage 3, the second key unlocking history is also absent.

  Next, the second person or the delivery company carries out the delivery process of the article 50 as shown in (b) of FIG. More specifically, first, the second person or the delivery company delivers the article 50 to which the locked first key 4 is attached to the article storage 3. Then, the second person or the delivery company stores the article 50 to which the first key 4 that has been delivered is attached in the article storage 3. Then, the second person or the delivery company uses the transaction management system 1 to perform a transaction to close the second key 31 of the article storage 3 in which the article 50 is stored. In addition, the second person or the delivery company, using the transaction management system 1, as shown in the situation 2 of FIG. 11 corresponding to FIG. 10 (b), the second key unlocking right is the first person. Perform a transaction to register the movement of the second key unlocking right. The other contents are the same as in the situation 1. That is, the transaction user is the second person or the delivery company, the article information of the article 50 is the electronic device A, the article identification information is the identifier of the first key 4, and the first key unlocking right is the first person It remains. Further, in the situation 2 of FIG. 11, the second person or the delivery company delivers the article 50, stores it in the article storage 3, and only performs the delivery process of closing the second key 31, Since the key 4 is not opened, the first key unlocking history is absent. Here, in FIG. 11, it is assumed that the unlocked state of the article storage 3 is the normal state. In this case, only the delivery process for closing the second key 31 has been performed, and the second key 31 has not been opened, so there is no second key unlocking history. On the other hand, the closed state of the article storage 3 may be a normal state. In this case, the second person or the delivery company may unlock the second key 31 once and store the item, and then perform a delivery process in which the second key 31 is closed. And in this case, since the second key 31 is once opened, the second key unlocking history is valid.

  Next, as shown in (c) of FIG. 10, the first person opens the second key 31 of the item storage 3 in which the item 50 is stored, and performs a first transaction to temporarily receive the item 50. . More specifically, the first party uses the transaction management system 1 to conduct a transaction to open the second key 31 of the item storage 3 in which the item 50 is stored. In the situation 3 of FIG. 11 corresponding to (c) of FIG. 10, the first person unlocked the second key 31 attached to the article storage 3, so the second unlocking history is It is recorded in the ledger 211 as being there. On the other hand, in the situation 3 of FIG. 11, since the first person has not opened the first key 4, the first key unlocking history is absent. Thereby, the first person can temporarily receive the article 50 with the locked first key 4 attached. Thereby, the first person brings the article back to a predetermined place such as a home, and confirms whether the article 50 which is the electronic device A in a state where the locked first key 4 is attached is operated or not. As it is possible, it can be examined whether or not the article 50 is unsuitable.

  Next, as shown in (d) of FIG. 10, the first person opens the first key 4 attached to the item 50 and performs a second transaction to truly receive the item 50. More specifically, the first person opens the first key 4 attached to the article 50 by using the transaction management system 1 when the article 50 operates and the article 50 is examined properly. Make a deal. Since the first person unlocks the first key 4 attached to the article 50 in the situation 4 of FIG. 11 corresponding to (d) of FIG. 10, the first unlocking history is It is recorded in the ledger 211. On the other hand, in the situation 4 of FIG. 11, since the first person has not opened the second key 31, there is no second key unlocking history. Thereby, the first person can unlock and remove the first key 4 attached to the article 50, so that the article 50 can be truly received and made his own.

  FIG. 12 is a flowchart for explaining an example of the characteristic operation of the transaction management system 1 according to the present embodiment. FIG. 12 shows a flowchart showing a process of using the opening of the first key 4 and the opening of the second key 31 as the electronic evidence of the transaction of the goods 50. .

  First, the computer of the transaction management system 1 registers that the first key unlocking right and the second key unlocking right belong to the first person (S11). For example, as described in (a) of FIG. 10, the second person who is the transaction user of the transaction management system 1 logs in to the transaction management system 1 using a terminal or the like, and the first key unlocking right Register that belongs to the first person. Further, as described in (b) of FIG. 10, the second person or the delivery company logs in to the transaction management system 1 using a terminal or the like, and the second key unlocking right is to the first person. Register belonging. As described above, by performing management to register that the first key unlocking right and the second key unlocking right belong to the first person, the second person who is attached to the article storage 3 is the first person. It is possible to open the key 31 to take out the article 50 from the article storage 3 and to open the first key 4 attached to the article 50 to take out the first key 4 from the article 50.

  Next, the computer of the transaction management system 1 determines whether the second key 31 has been opened (S12). The computer of the transaction management system 1 determines whether or not the first person causes the article storage 3 to open the second key 31 using a terminal or the like, as described in, for example, (c) of FIG. doing. It should be noted that when the first person requests unlocking of the second key 31, the article storage device 3 sends the second key to the first user who is the transaction user to the computer of the transaction management system 1, ie, the server device 2. It is confirmed whether or not the unlocking right belongs, and if it belongs, the second key 31 is unlocked.

  If it is determined in step S12 that the second key 31 has been opened (Yes in S12), the computer of the transaction management system 1 manages that the first transaction for temporarily receiving the article 50 is established (S13). More specifically, when the computer of the transaction management system 1 acquires from the article storage 3 that the second key 31 of the article storage 3 in which the article 50 is stored is opened, the first person can It manages as the 1st transaction which receives goods 50 from 2 persons temporarily is concluded. In the present embodiment, the transaction management system 1 manages that the first transaction is established by recording the fact that the second key 31 has been opened in the ledger 211.

  Next, the computer of the transaction management system 1 determines whether the first key 4 has been opened (S14). For example, as described in (d) in FIG. 10, the computer of the transaction management system 1 has the first person open the first key 4 attached to the article 50 using a terminal or the like. Is determined. The first key 4 has a first key unlocking right belonging to the first user who is a transaction user, in the computer of the transaction management system 1, that is, the server device 2, when the first person issues an unlocking request. If it belongs, the first key 4 is unlocked.

  If it is determined in step S14 that the first key 4 has been opened (Yes in S14), the computer of the transaction management system 1 manages that the second transaction for truly receiving the item 50 is established (S15). More specifically, when the computer of the transaction management system 1 acquires from the first key 4 that the first key 4 has been opened, the second transaction that the first person truly receives the article 50 after reviewing Manage as established. In the present embodiment, the transaction management system 1 manages that the second transaction has been established by recording in the ledger 211 that the first key 4 has been opened.

  Subsequently, the detailed operation of the transaction management system 1 in the present embodiment will be described.

  13A and 13B are sequence diagrams for explaining an example of the operation of the transaction management system 1 according to the present embodiment. FIG. 13A shows a situation 1 showing a shipping process in which the second person prepares to ship the article 50 to the first person, and the article store 3 in which the delivery company or the second person is in a predetermined place. A situation 2 indicating a delivery process of delivering, storing the object 50 in the article storage 3 and closing the second key 31 is shown. In FIG. 13B, the first person removes the first key 4 attached to the article 50 and the situation 3 until the first person performs the first transaction to temporarily receive the article 50 from the article storage 3. A situation 4 is shown until a second transaction is performed to truly receive the item 50.

  First, situation 1 will be described.

  When the second person arranges to deliver the article 50 with the first person, the second person performs the shipping process of the article 50. More specifically, after attaching the first key 4 to the article 50, the second person logs in to the transaction management system 1 using a terminal or the like, and makes a shipping process request.

  Then, first, in the transaction management system 1, the authentication unit 202 performs a user authentication process to authenticate whether the second person is the correct transaction user (S101). In step S101, when it is authenticated that the second person is the correct transaction user, the authentication unit 202 performs an acceptance process for accepting the shipping process request (S102). Next, the authentication unit 202 notifies the management unit 201 of the shipping process request.

  Next, when the management unit 201 is notified of the shipping process request, the management unit 201 notifies the first key 4 of the first key unlocking request. Further, the management unit 201 performs article information registration for recording article information of the article 50 input by the second person via the terminal in the ledger 211 (S103). Here, the item information of the item 50 is, for example, information indicating that the item 50 is the electronic device A, and information indicating that the item identification information of the item 50 is the identifier of the first key 4.

  Next, when the first key control unit 401 of the first key 4 is notified of the first key unlocking request, the server device 2 receives the first key unlocking right for the second user who is the transaction user. It is checked whether it belongs or not, and if it belongs, the first key lock processing is performed to lock the first key 4 (S104). After performing the first key locking process, the first key control unit 401 of the first key 4 notifies the management unit 201 of first key locking information indicating that the first key 4 has been locked. The order of steps S103 and S104 may be reversed. Moreover, although it demonstrates as that the articles | goods 50 are specified using the identifier of the 1st key 4 below, it does not restrict to this. The identifier of the item 50 may be used to identify the item 50. In this case, in the item identification information of the item 50, information indicating the identifier of the item 50 is recorded.

  Next, when the management section 201 is notified of the first key lock information, the management section 201 records a first key lock history indicating that the first key 4 is locked in the ledger 211 (S105). Then, the management unit 201 determines that the first key unlocking right belongs to the first person according to the operation input of the second person via the terminal, the second key unlocking right is the second person or the delivery company The unlocking right is registered by recording in the ledger 211 that the device belongs to (S106). Next, the management unit 201 completes the preparation for shipping of the article 50 by the second person, and creates article shipping notification information indicating that the transaction for performing the procedure for shipping the article 50 is performed (S107). Notify the person. The management unit 201 may further notify the system used by the delivery company of the information indicating the created item shipping notice.

  Subsequently, situation 2 will be described.

  The delivery company or the second party carries out the delivery process of the article 50. More specifically, the delivery company or the second person first delivers the article 50 to which the locked first key 4 is attached to the article storage 3. Then, the second person or the delivery company stores the article 50 to which the first key 4 that has been delivered is attached in the article storage 3. After that, the delivery company or the second person logs in to the transaction management system 1 using a terminal or the like and makes a delivery processing request.

  Then, first, in the transaction management system 1, the authentication unit 202 performs a user authentication process to authenticate whether the delivery company or the second person is the correct transaction user (S108). In step S108, when the delivery company or the second person is authenticated as the correct transaction user, the authentication unit 202 performs an acceptance process for accepting the delivery process request (S109). Next, the authentication unit 202 notifies the article storage 3 of the second key unlocking request.

  Next, when the second key unlocking request is notified, the article storage 3 first performs object recognition that recognizes whether or not an article is stored in the article storage 3 (S110). Then, the article storage 3 confirms whether or not the second key unlocking right belongs to the server apparatus 2 to the delivery company or the second person who is the transaction user, and if it belongs, the second key 31 A second key locking process is performed to lock the key (S111). After performing the second key closing process, the article storage 3 notifies the management unit 201 of second key closing information indicating that the second key 31 has been closed.

  Next, when the second key lock information is notified, the management unit 201 records, in the ledger 211, a second key lock history indicating that the second key 31 is locked (S112). Next, the management unit 201 records that the second key unlocking right belongs to the first person according to the operation input of the second person via the terminal, thereby recording the second key unlocking right. The movement is registered (S113). Next, the management unit 201 creates article delivery notification information indicating that the delivery of the article 50 by the delivery company or the second person is completed and the transaction for storing the article 50 is performed in the article storage 3 (S114). , Notify the first person.

  Subsequently, situation 3 will be described.

  The first person opens the second key 31 of the item storage 3 in which the item 50 is stored, and performs a first transaction to temporarily receive the item 50. More specifically, the first person first moves to the installation place of the article storage 3. After that, the first person logs in to the transaction management system 1 using a terminal or the like and makes a provisional receipt request.

  Then, first, in the transaction management system 1, the authentication unit 202 performs a user authentication process to authenticate whether the first person is the correct transaction user (S115). In step S115, when it is verified that the first person is the correct transaction user, the authentication unit 202 performs an acceptance process for accepting the temporary receipt request (S116). Next, the authentication unit 202 notifies the article storage 3 of the second key unlocking request.

  Next, when the article storage 3 is notified of the second key unlocking request, first, whether or not the second key unlocking right belongs to the first person who is the transaction user in the server device 2 or not The second key unlocking process is performed to unlock the second key 31 when belonging (S117). Thereby, the first person can take out the article 50 to which the locked first key 4 is attached from the article storage 3 and temporarily receive the article 50 temporarily. Next, after performing the second key unlocking process, the article storage 3 performs object recognition that recognizes whether an article is stored in the article storage 3 (S118). In step S118, when recognizing that the article is not stored in the article storage 3, the article storage 3 notifies the management unit 201 of the second key unlocking information indicating that the second key 31 has been unlocked. .

  Next, when the second key unlocking information is notified, the management unit 201 records a second key unlocking history indicating that the second key 31 is unlocked in the ledger 211 (S119), It manages that 1 dealings are concluded (S120).

  Finally, situation 4 will be described.

  If the first person examines that the temporarily received article 50 is an appropriate article, the first person opens the first key 4 attached to the article 50 and performs a second transaction to truly receive the article 50. More specifically, the first person logs in to the transaction management system 1 using a terminal or the like and makes a main receipt request when the article 50 operates and the article 50 is examined properly. .

  Then, first, in the transaction management system 1, the authentication unit 202 performs a user authentication process to authenticate whether the first person is the correct transaction user (S121). In step S121, when it is authenticated that the first person is the correct transaction user, the authentication unit 202 performs an acceptance process for accepting the main receipt request (S122). Next, the authentication unit 202 notifies the first key 4 of the first key unlocking request.

  Next, when the first key control unit 401 of the first key 4 is notified of the first key unlocking request, first of all, the server device 2 unlocks the first key to the first person who is the transaction user. It is confirmed whether or not the right belongs, and when it belongs, the first key unlocking process is performed to unlock the first key 4 (S123).

  Next, the buyer 62 moves to the item storage 3a, opens the second key 31 of the item storage 3a using the transaction management system 1, and performs a first transaction to temporarily receive the item 50a. Thereby, the buyer 62 can bring the product 50a back to a predetermined place such as a home and check whether the product 50a operates. That is, the buyer 62 can check whether the product 50a is unsuitable or not by checking the operation of the product 50a with the first key 4a attached.

  Next, when the buyer 62 checks that the product 50a operates and the product 50a is appropriate, and confirms that the product 50a at hand has no problem, the buyer 62 uses the transaction management system 1 to select the product. A transaction is performed to open the first key 4a attached to 50a. Thus, the buyer 62 can unlock and remove the first key 4a attached to the item 50a, so that the item 52a can be truly received. Then, the transaction management system 1 performs a transaction for transferring the payment of the buyer 62 temporarily deposited to the seller 61. In this way, it is possible to buy and sell the product 50a between the seller 61 and the buyer 62 and safely and reliably carry out the transaction.

  Subsequently, the detailed operation of the transaction management system 1 in the present embodiment will be described.

  16A and 16B are sequence diagrams for explaining an example of the operation of the transaction management system 1 in the present embodiment. FIG. 17 is a diagram showing an example of the transaction history and the unlocking right holder in the present embodiment. Here, it is assumed that the transaction management system 1 records transactions other than the unlocking of the first key 4a and the second key 31a in the ledger 211 as a transaction history.

  First, the selling process of the seller 61 who is the second person shown in FIG. 16A will be described.

  The seller 61 sells the product 50a in an exhibition list viewable on the WEB managed by the server device 2. That is, the seller 61 logs in to the server device 2 and makes an exhibition request for registering the product 50a in the exhibition list. Then, first, the server device 2 performs a user authentication process to authenticate whether the seller 61 is the correct transaction user by the authentication unit 202, and when it is authenticated that the seller 61 is the correct transaction user, the exhibition Perform reception processing to receive a request. Next, the server device 2 executes exhibition registration in the management unit 201 to register the product 50a notified by the seller 61 in the exhibition list, and as shown in FIG. 17, the seller 61 registers the product 50a in the exhibition list A transaction history indicating that is recorded in the ledger 211. Here, the item information of the item 50a is also registered in the exhibition list.

  Next, the exhibition reference process and the purchase start process of the buyer 62 who is the first person shown in FIG. 16A will be described.

  The buyer 62 first logs in to the server device 2 and makes an exhibition list reference request for referring to the exhibition list managed by the server device 2. Then, first, the server device 2 performs user authentication processing to authenticate whether the buyer 62 is the correct transaction user by the authentication unit 202, and when it is authenticated that the buyer 62 is the correct transaction user, the exhibition Perform reception processing to receive a list reference request. Next, the server device 2 allows the buyer 62 to refer to the exhibition list based on the exhibition list reference request in the management unit 201. As a result, the buyer 62 can refer to the exhibition list managed by the transaction management system 1.

  Here, it is assumed that the buyer 62 wants to purchase a product 50a on which the seller 61 makes a sale in the sale list. In this case, the buyer 62 requests the server device 2 to make a purchase request for buying the product 50a, and deposits the payment by the purchase credit card or an electronic method such as bank transfer to the server device 2 as a purchase start transaction. As a temporary deposit. Here, the payment is an amount necessary for purchasing the product 50a, and may include a delivery fee. Then, as illustrated in FIG. 17, the server device 2 records, in the ledger 211, a transaction history indicating that the buyer 62 has started purchasing the product 50a.

  Next, the shipping process of the seller 61 who is the second party shown in FIG. 16A will be described.

  When the seller 61 is notified of the purchase request for the product 50 a from the transaction management system 1, the seller 61 performs the shipping process using the transaction management system 1. That is, when the seller 61 receives a request for purchase of the product 50a from the server device 2, the seller 61 first attaches the first key 4a to the product 50a. Thereafter, the seller 61 uses the terminal or the like to log in to the server device 2 and register the product identification information of the product 50a, the first key unlocking right, the second key unlocking right, and the first key 4 Notify the first key unlock request. Here, as illustrated in FIG. 17, the server device 2 records, in the ledger 211, a transaction history indicating that the seller 61 has registered the first key unlocking right of the first key 4a attached to the product 50a. When the first key unlocking request is notified, the first key 4 confirms to the server apparatus 2 whether the seller 61 who is the transaction user belongs to the first key unlocking right or not. In this case, the first key 4 is closed. The server device 2 may also record in the ledger 211 that the first key 4a attached to the product 50a is locked as the transaction history.

  Next, the seller 61 logs in to the server device 2 and creates a product shipping start notification indicating that a transaction to carry out the procedure for shipping the product 50 has been made, and sends a request to deliver the product 50a to the product storage 3a. Make a product delivery request to indicate. Then, as illustrated in FIG. 17, the server device 2 records, in the ledger 211, a transaction history indicating that the seller 61 has started shipping the product 50a. Further, the server device 2 outputs the product delivery request to, for example, the product transport unit 71 of a system used by the delivery company 70. As a result, it is possible to make a transaction that causes the delivery company 70 to deliver the item 50a to the item storage 3a. Further, the product delivery start notification may also serve as a product delivery request.

  Next, the delivery process of the delivery company 70 shown in FIG. 16A will be described.

  First, when the delivery company 70 receives a product delivery request from the product delivery unit 71, the delivery company 70 makes a reservation in the reservation management unit of one vacant item storage 3a among the plurality of product storages 3 of the delivery box. Next, the delivery company 70 delivers the goods 50a attached with the locked first key 4a to the goods storage 3a. Next, the delivery company 70 stores the goods 50a to which the delivered first key 4a is attached in the goods storage 3a. Thereafter, the delivery company 70 logs in to the server device 2 using a terminal or the like, and makes a second key lock request to lock the second key 31 attached to the item storage 3a. Then, the article storage 3 performs object recognition that recognizes whether or not an article is stored in itself, and if stored, confirms whether the second key unlocking right belongs to the delivery company 70 or not. Do. The article storage 3a performs a second key closing process of closing the second key 31a when the second key unlocking right belongs to the delivery company 70. After confirming that the second key 31a of the article storage 3a is locked, the delivery company 70 registers the article delivery completion notification in the server device 2 via the article transport unit 71. When the product delivery completion notification is registered, the server apparatus 2 sends a product delivery completion notification indicating that the product 50a has been delivered to the product storage 3a to the buyer 62, and gives the buyer 62 the second key unlocking right. Register to move. It should be noted that when the server apparatus 2 is notified of the second key unlocking information indicating that the second key 31a has been locked from the article storage 3a together with the goods delivery completion notification, the second item delivery completion notification and the second Registration of the movement of the key unlocking right may be performed. In addition, the server device 2 may register the transfer of the product delivery completion notification and the movement of the second key unlocking right when notified of the second key locking information. Furthermore, the server device 2 notifies the completion of the product delivery, etc., and as shown in FIG. 17, records in the ledger 211 a transaction history indicating that the delivery company 70 stored the product 50a in the product storage 3a. 2 Register to move the key unlocking right to the buyer 62.

  Next, the goods temporary receipt processing of buyer 62 who is the 1st person shown in Drawing 16B is explained.

  First, the buyer 62 moves to the installation place of the item storage 3a, logs in to the server device 2, and makes a temporary receipt request for the item 50a. Then, first, the server device 2 causes the authentication unit 202 to perform user authentication processing to authenticate whether the buyer 62 is the correct transaction user, and when it is authenticated that the buyer 62 is the correct transaction user, the second A key unlocking request is notified to the article storage 3a. When notified of the second key unlocking request, the article storage 3a first confirms to the server device 2 whether or not the second key unlocking right belongs to the buyer 62, and if it belongs, A second key unlocking process is performed to unlock the second key 31a. Thereby, the buyer 62 can take out the goods 50a to which the locked first key 4a is attached from the goods storage 3a and temporarily receive the goods 50a. Next, after performing the second key unlocking process, the article storage 3a performs object recognition that recognizes whether an article is stored in the article storage 3a. When recognizing that the article is not stored, the article storage 3a notifies the server device 2 of second key unlocking information indicating that the second key 31a has been unlocked. In the server device 2, when the second key unlocking information is notified, as shown in FIG. 17, the buyer 62 temporarily receives the product 50a stored in the product storage 3a, and the first transaction is established. Are recorded in the ledger 211.

  Next, the product review OK process of the buyer 62 who is the first person shown in FIG. 16B will be described.

  The buyer 62 logs in the server device 2 using a terminal or the like when making a check that the product 50a is operating and the product 50a is appropriate, and performs a product OK notification. The product OK notification corresponds to the main receipt request described in the above embodiment. Then, the server device 2 authenticates whether the buyer 62 is the correct transaction user by the authentication unit 202, and if it is authenticated that the buyer 62 is the correct transaction user, the first key unlocking request is 1 Notify the key 4a. When notified of the first key unlocking request, the first key 4a first confirms to the server device 2 whether or not the first key unlocking right belongs to the buyer 62, and when it belongs, A first key unlocking process is performed to unlock the first key 4a. After the first key unlocking process, the first key 4a notifies the server device 2 of first key unlocking information indicating that the first key 4a has been unlocked. Thus, the buyer 62 can unlock and remove the first key 4a attached to the item 50a, so that the item 52a can be truly received. Then, when the first key unlocking information is notified, as shown in FIG. 17, the server device 2 unlocks the first key 4a attached to the item 50a by the buyer 62, and the second transaction is established. A transaction history indicating that the transaction has been made is recorded in the ledger 211. Further, the server device 2 transfers the deposit of the buyer 62 to the seller 61.

  Even if the buyer 62 touches or holds the portable terminal possessed by the buyer 62 over the first key 4a and the second key 31a of the article storage 3a, the buyer 62 opens the first key 4a and the second key 31a of the article storage 3a. Good. In this case, the buyer 62 may log in to the server device 2 and make the portable terminal acquire information indicating the registered buyer 62 before going to the place of the item storage 3a. Then, by touching or holding the portable terminal over the first key 4a and the second key 31a of the article storage 3a, the first key unlocking request or the second key unlocking request as well as the information indicating the buyer 62 itself is proximity wireless Transmission should be possible.

  On the other hand, the product review NG process of the buyer 62 who is the first person shown in FIG. 16B will be described.

  If the buyer 62 checks that the product 50 is not appropriate, such as the product 50a does not operate or the product 50a is different from the purchase request (order), the product 62 returns the product 50a to the product storage 3a and uses a terminal or the like. Log in to the server device 2 and make a product NG notification. Then, the server device 2 authenticates whether the buyer 62 is the correct transaction user at the authentication unit 202, and if it is confirmed that the buyer 62 is the correct transaction user, the second key lock request is issued as an article It notifies storage 3a. When notified of the second key closing request, the item storage 3a performs object recognition that recognizes whether or not an item is stored, and when it is recognized that an item is stored, the second key is closed. Perform lock processing. After performing the second key closing process, the article storage 3a notifies the server device 2 of second key closing information indicating that the second key 31a has been closed. When the second key lock information is notified, the server device 2 records, in the ledger 211, a transaction history indicating that the buyer 62 has returned the product 50a to the item storage 3a, as shown in FIG. Further, the server device 2 outputs a return request to, for example, the commodity transport unit 71 of the system used by the delivery company 70, and refunds the deposit of the buyer 62 by an amount obtained by subtracting a fee such as a cancellation fee.

  When the delivery agent 70 receives a return request from the goods transport unit 71, the delivery company 70 moves to a place where the goods storage 3a is installed, takes out the goods 50a from the goods storage 3a, and returns the goods 50a to the seller 61. When receiving the notification that the return has been completed from the product transport unit 71, the server device 2 records a transaction history indicating that the delivery company 70 has returned the product 50a to the seller 61 in the ledger 211, and a fee such as a cancellation fee. Send money to the seller 61.

  In this manner, the seller 61 and the buyer 62 send and receive the goods 50a to which the first key 4a is attached, so that the seller 61 sends a certain thing to the buyer 62 even via the delivery company 70. It becomes possible. That is, it is possible to buy and sell the product 50a between the seller 61 and the buyer 62 and safely and reliably carry out the transaction.

  In the product evaluation NG process of the buyer 62, when the buyer 62 returns the product 50a to the product storage 3a, the product storage 3a further confirms that the first key 4a is attached to the product 50a. May be

  For example, the article storage 3a communicates with the first key 4a to authenticate that the first key 4a is not unlocked. Furthermore, the first key 4a may be provided with a functional unit that enables identification of the product 50a itself. Thereby, the first key 4a is attached to another item 50a, the weight disguised item 50a and another object are attached, or the first item 4a is attached to a broken item of the same type as the item 50a Can be easily detected.

  The functional unit may be any of the above-described various sensors or an RFID reader, but is not limited thereto. A functional part should just be what can specify other goods 50a itself.

  The functional unit is the above-described RFID reader, and may recognize whether or not the article 50 is stored in the article storage 3 using the RFID at the time of the product review NG process. More specifically, the article storage 3a may further include an RFID reader, and the first key 4a or the article 50a may be further attached with an RFID indicating the article 50a. In this case, after managing that the first transaction has been established, the transaction management unit 2012 confirms that the item 50a is physically stored in the item storage 3a by the item storage 3a reading the RFID with the RFID reader. What is done and that the second key 31a is closed is acquired from the item storage 3a, and if the first key 4a is not opened, it may be managed as if the second transaction has not been established.

  In addition, for example, when the item storage 3a is not the product 50 but a substitute camouflage item is placed and the door is closed, an alarm sound is emitted and the door is opened to continue the return procedure. You may refuse.

  Further, in the product evaluation NG process of the buyer 62, the buyer 62 may use a substitute article storage 3 instead of returning the same to the same article storage 3a as at the time of temporary receipt. As a result, the article storage 3a can be avoided from being occupied for a period from the temporary receipt of the goods 50a to the establishment of the contract, that is, the establishment of the first transaction and the second transaction. Is possible.

  The movement of the key unlocking right holder shown in FIG. 17 may not be performed by the seller 61 or the delivery company 70 but may be automatically executed by the program according to the contents of the transaction such as the shipping process and the delivery process.

[Effects, etc.]
As described above, according to the transaction management system 1 and the like of the present embodiment, the first person is the buyer 62, the second person 61 is the seller, and the article 50 is the second person. It may be a product 50a to be provided. In this case, the transaction for temporarily receiving the item 50 is a transaction for confirming whether the item 50a is the item desired by the first person before deciding to purchase the item 50a, and makes the item 50 true. The transaction to be received may be a transaction for which the purchase decision of the product 50a has been made.

As described above, in the transaction management system 1 and the like according to the present embodiment, the commodity 50a is used by utilizing the open / close history of the first key 4a and the second key 31a opened and closed by electronic processing as the transaction history of the commodity 50a. Can prevent the buyer 62 from receiving an inappropriate product. In addition, even if the buyer 62 receives an inappropriate product, the transaction history of the product 50a is surely left as electronic evidence, so the seller 61 who has given the product 50a is returned or exchanged. Etc. can be done properly. That is, according to the transaction management system 1 and the like of the present embodiment, it is possible to carry out the transaction of the exchange of the appropriate product 50a more safely and reliably without facing each other. As a result, it is possible to suppress disguising the article 50 or disguising the exchange transaction, thereby saving energy such as reducing the article 50 itself used for disguising, reducing energy consumption for return or exchange processing, etc. Can be
Ru.

  Note that the ledger 211 may be a distributed ledger in which a plurality of ledgers having the same contents are built on the basis of a block chain. This makes it possible to raise the tamper resistance of the open / close history of the first key 4 and the second key 31. As a result, the reliability of the electronic evidence indicating that the first and second transactions, which are exchange transactions of the articles 50 recorded in the ledger 211, are established is improved. It is possible to more reliably carry out the transaction of exchange.

  There is also a smart contract among the functions realized by the block chain. Here, the smart contract is a contract description of 1 condition 1 execution such that the program in which the transaction condition is described is executed when the transaction condition is satisfied.

  According to this embodiment, since it is possible to confirm that the first transaction has been completed by opening the second key 31 and the second key 4 by opening the first transaction, it is possible to make a purchase contract of goods a smart contract. It can be handled by. That is, by using the first key 4 and the second key 31, it can be realized by electronically detecting a physical trigger which is a condition under which a smart contract regarding purchase transaction of goods is established.

  If the buyer 62 does not return the product 50a and does not unlock the first key 4a after the temporary receipt process of the product 50a, that is, after the establishment of the first transaction, even if a predetermined period has passed, the server apparatus The second contract may be concluded when the sales contract of the article 50a is established, that is, when the second transaction is concluded.

  If the buyer 62 does not electronically unlock the first key 4a after the temporary receipt processing of the product 50a, that is, after the establishment of the first transaction, the server device 2 releases the goods by the destructive action. The contract of sale 50a may be concluded, that is, when the second transaction is concluded, the contract may be concluded. In this case, the first key 4 a includes the key destruction detection unit 402. As a result, by returning only the first key 4a that has been unlocked by the destructive action and removed from the product 50a, it is possible to suppress the action that prevents the establishment of the second transaction.

  Further, an impact sensor may be attached to the product 50a, and a mechanism may be added to determine whether the product 50a itself is harmed.
