The storage unit includes a communication program for connecting to the notary institution 15, an operation program for performing product purchase processing, The terminal ID to be specified is stored. The seller terminal 13 is a terminal for a seller to register a product to be sold in the notary institution 15 and has a display unit, a storage unit, an input unit, a communication control unit, and the like.
It stores a communication program for connecting to the notary institution 15, an operation program for performing product registration processing, a terminal ID for specifying the terminal, and the like.

The notary institution 15 is a neutral institution that sells merchandise registered by the seller to the buyer, and is composed of a computer such as a server. Notary institution 15
Is a registration DB (Data Base) 21 as shown in FIG.
, Price DB 25, product DB 23, and history DB 27
And a control unit 29. The registration DB 21 stores user information that is information of users (purchasers / sellers) registered in the present system. The user information includes data items such as a user code for specifying the user, a name (purchaser name / seller name), an address, a telephone number, and the like, as shown in FIG. 3, for example. Among them, the user code is an identification code given by the notary authority 15 when the user registers in the present system. When the user uses the present system, the notary institution 15 stores the user code of the user in the registration DB.
Check that it is registered in 21. The registration process of the user to the present system will be described later.

The product DB 23 stores product information (product name, product code for specifying the product, stock quantity, seller user code, etc.) for each product registered by the seller using the seller terminal 13. ) Is stored. Price DB25,
For each product registered by the seller using the seller terminal 13, a price table (FIG. 4) indicating the number of purchases and the price per product corresponding to the number of purchases is stored. For example, in the price table shown in FIG. 4, the price of a product when the number of purchases is one is 10,000 yen, and the number of purchases is one.
This indicates that the price per product in the case of 0 products is 7,500 yen. The data of the price table is set by the seller of each product and stored in the price DB 25. The history DB 27 stores history information of a completed transaction. The control unit 29 processes a product purchase request from a purchaser, a product registration request from a seller, and the like. When the transaction is established, the control unit 29 notifies the settlement institution 17 of the settlement information (the purchaser / seller user code, the settlement amount, etc.) necessary for the settlement of the transaction.

The settlement institution 17 has, for example, a table for associating a user code and an account number with respect to the user registered in the present system, and according to the settlement information notified from the notary institution 15, the account of the purchaser. Is instructed to transfer the predetermined amount from the account to the seller's account. The bank host 19 has a payment account of the user registered in the present system, and performs a transfer process in accordance with an instruction from the payment institution 17.

In this electronic settlement system, in order to maintain the security of transactions, users (purchaser /
Only the seller). Next, a registration process for a user to register in the system will be described. For example, the purchaser inputs a registration request to the purchaser terminal 11.
In response to this input, the purchaser terminal 11 displays a registration screen for inputting items such as name, address, telephone number, and the like. The purchaser inputs all items and selects, for example, an input completion button. In response to this selection, the buyer terminal 11
The input data (registration data) is transmitted to the notary institution 15 via the network 20 together with the user registration request. Note that the transmitted data is provided with the terminal ID of the purchaser terminal 11 of the transmission source.

The notary institution 15 stores the registration data in the registration DB 21 in response to receiving the user registration request. At this time, the notary institution 15 generates a user code for specifying the user, and stores it in the registration DB 21 together with the registration data. The method of generating the user code is arbitrary, for example,
It may be generated randomly using a random number generation unit (not shown). After updating the registration DB 21, the notarization institution 15 transmits a registration completion signal to the purchaser terminal 11 having the terminal ID assigned to the registration data via the network 20. The purchaser terminal 11 that has transmitted the registration request receives the update completion signal and displays a message indicating that the registration has been completed. As a result, the registration process is completed, and the purchaser can use the present system. The seller registration method using the seller terminal 13 is the same as the above-mentioned registration method.

The notary institution 35 is a neutral institution for auctioning the merchandise registered by the seller, and comprises a computer such as a server. The notary institution 35 includes a registration DB 41, an auction DB 43, a history DB 47, and a control unit 49, as shown in FIG.

The registration DB 41 has the same configuration as the registration DB 21 in the first embodiment. This system is
In order to maintain the security of the transaction, the system can be used only by the registrant, as in the first embodiment. The registration method for the present system is the same as the registration method in the first embodiment. The auction DB 43 is a DB for registering information (auction information) of commodities exhibited by the seller in the auction. The auction information includes, for example, the product name of the product to be exhibited, the number of products, the user code of the seller, and the like. The registration processing to the auction DB 43 will be described later. History DB4
Numeral 7 stores history information of transactions that have been completed in the auction. The control unit 49 manages auction information registered by the seller, performs auctions, and the like. When a transaction is established, the controller 49 sets payment information (a purchaser / seller user code, a user code, Amount, etc.) to the settlement institution 37.

Next, a description will be given of a registration process in which a seller uses the seller terminal 33 to register, in the notary institution 35, a product to be exhibited in an auction. First, the seller inputs an auction registration request to the seller terminal 33. Respond to this input,
The seller terminal 33 displays the product name, the number of stocks,
A registration screen for allowing the seller to input information (registration data) such as the user code of the seller is displayed. The seller inputs all of these data and selects, for example, an input complete button. In response, the seller terminal 33 transmits the input registration data together with the auction registration request to the notary authority 35 via the network 40.

The notary institution 35 responds to the auction registration request from the seller terminal 33 and registers the received registration data in the auction DB 43 as auction data. At the time of this registration, the notary institution 35 generates an auction code for specifying the auction data, and stores it in the auction DB 43 together with the corresponding auction data. After the registration, the notary institution 35 transmits a registration completion signal to the seller terminal 33. The seller terminal 33 receives the registration completion signal and displays a message indicating that the registration has been completed.
Thereby, the seller can register the goods to be exhibited in the auction in the notary institution 35.

The information registered in the auction DB 43 by the above method is presented to the user at a predetermined timing, for example.
The presentation method is arbitrary, and, for example, the notary authority 35 sends the latest auction information (for example, 1) in response to a request from the user.
Auction information scheduled within a month). When there is an auction to be participated, the user applies for the auction. For example, the user inputs a user code and a desired auction participation application request to the purchaser terminal 31, and the purchaser terminal 31
0 to the notary authority 35. The transmitted participation application request includes an auction code specifying an auction.
The notary institution 35 has a participant table for registering participants for each auction. The notary institution 35 responds to the participation application request from the purchaser terminal 31, confirms that the received user code is registered in the registration DB 41,
The user code is registered in the corresponding auction participant table. You.

Since the present system conducts transactions online, taking into account a decrease in response due to line load,
A capacity may be set for each transaction (auction). In this case, for example, the notary institution 35 terminates the reception if the number of applications is limited in each auction.

During the auction, the notary institution 35 generates a group ID corresponding to the auction code before starting the auction, and transmits the data to the participants all at once (multicast). To distribute. For example, before the auction starts, a user who has applied for auction participation by the above-described registration process inputs a user code and an auction start request to the purchaser terminal 31. The input user code and the auction start request are transmitted to the notary institution 35 via the network 40. In response to the auction start request from the purchaser terminal 31, the notary institution 35 searches the participant table in which the received user code is stored, and thereby the auction in which the sender user has applied for participation. Identify the auction code for. Next, the notary institution 35 transmits the group ID corresponding to the auction code to the purchaser terminal 31 of the transmission source. The purchaser terminal 31 stores the received group ID.

At the start of the auction, the notary institution 35
The start of auction is notified to each purchaser terminal 31 to which D has been distributed. In response to receiving the notification, each purchaser terminal 31 having the group ID displays an auction start message. The participant inputs a desired price into the purchaser terminal 31. FIG. 10 shows an example of a display screen (auction screen) of the purchaser terminal 31 at this time. As shown in the figure, the auction screen displays a product name and a stock quantity, and has an input field C3 for inputting a desired price. Further, the auction screen includes an area (price display area) A1 in which a graph showing a change in price presented by each participant in the auction is displayed.

The participant, for example, inputs a desired price in the input field C3 of the auction screen shown in FIG. 10, and selects a send button. In response to this selection, the purchaser terminal 31 transmits the entered price, user code, and group ID to the notary institution 35 via the network 40. In response, the notary authority 35 temporarily stores the received price and the user code, and stores the received price in the group I.
A broadcast is sent to each purchaser terminal 31 to which D has been assigned. Each purchaser terminal 31 updates the graph displayed in the price display area A1 of the auction screen according to the price received from the notary authority 35. Thereby, each participant can know the price presented by the other participants in real time. In addition,
The display method of the price presented by each participant does not need to be limited to a graph, and may be displayed by a numerical value, for example.

At the elapse of a predetermined time from the start of the auction, the notary
5 ends the reception of the price from the participant. Notary institution 3
Reference numeral 5 refers to the received price from the participant, selects user codes by the same number as the number of goods in stock in the order of the highest price, and transmits a message for determining a successful bid. Further, a message to the effect that no successful bid was made is transmitted to the other participants, and the auction ends. After the auction ends, the notary authority 35
The information of the successful bidder (name, address, etc.) is notified to the seller, and an instruction to settle the transaction including the transaction price is transmitted to the settlement institution 37. At this time, the notary institution 35 determines, for example, the lowest price among the prices presented by the successful bidder as the successful bid price. In response to this instruction, the clearing house 37 instructs the bank host 39 to transfer the amount (successful bid price) instructed from the successful bidder's account to the seller's account. The bank host 39 performs a transfer process according to this instruction. This enables real-time auctions online. Also in this case, the information of the user participating in the auction is not notified to other participants and the seller, so that privacy is protected.

The notary institution 35 may determine the amount presented by each successful bidder as the respective successful bid price.

As the auction proceeding method, the same number of successful bidders as the number of stocks are determined at a time. However, it is also possible to conduct auction for each product and select a person who gives a high price in each auction.

Further, it is also possible to set a minimum price for each product exhibited by the seller and prevent a successful bid at a price lower than that price.

(Third Embodiment) Next, a third embodiment of the present invention will be described.
As an embodiment of the present invention, for example, an electronic transaction system for trading various information (contents) registered by users between users will be described. The content is

As one function of protecting the content provider,
A user who purchases the content only with an unreasonably low purchase price may be detected from the history DB 67, and the use of the system may be restricted or prohibited for the user.
In this case, for example, the notary institution 55 reads out the purchase amount in each transaction from the history DB 67 for each user code of the purchaser, and the purchase amount becomes a predetermined amount (for example, “1 yen”).
Etc.) The following transactions are counted, and it is determined whether or not the number is equal to or more than a predetermined ratio (for example, “80%”) of the total number of transactions. If the ratio is equal to or more than the predetermined ratio, the notary institution 55
Below "yen", the content may not be purchased, and the use of this system may be prohibited. Alternatively, the content provider may set a minimum price in advance, and the notary institution 55 may not sell at a price lower than the set minimum price.

When the notarization institution 55 receives the purchase request, it notifies the user terminal 51 of the content provider of the purchase request, and the purchaser and the seller communicate the price of the content via the notary institution 55. May be negotiable. In this case, for example, the user terminal 51 of the content seller
Needs to be in a situation where it is possible to notify the originator of the content that a purchase request has occurred, such as when it is connected to the notary institution 55. The notary institution 55 notifies the notification seller of the occurrence of the content purchase request. The notified seller transmits the desired selling price of the content to the notary authority 55. The notary institution 55 sends the price from the seller to the user terminal 51 of the purchaser. The purchaser sees the price from the seller and, if convinced, operates the transaction, and if not satisfied, transmits the desired purchase price to the notary institution 55.
In this way, the notary institution 55 causes the seller and the buyer to exchange the prices offered by each other, for example, until mutual agreement is obtained. This makes it possible to negotiate the price of the content.

As another settlement method for buying and selling contents, for example, a prepaid card storing electronic money information having a monetary value may be used (micropayment system).

Further, as one of the functions of protecting the seller in the electronic transaction systems of the first and second embodiments, after the purchase,
The buyer who has returned the merchandise may be restricted or prohibited from the next transaction as a penalty.

In the first and second embodiments,
Notaries 15 and 35 store the purchase history of each purchaser in the history DB
27, 47, and may be disclosed in response to a request from a seller.

It is also possible to assign a nickname to each user of the present system and to use the nickname instead of the real name in the transaction. In this case, only the notary institution stores the real name of each user and the nickname for it. This makes it possible to realize an electronic transaction system capable of identifying each user without disclosing the real name of the user.
