DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic mail (hereinafter simply referred to as "e-mail address") or the like when a purchaser purchases a product from a seller during a commercial transaction on a network. The present invention relates to a product electronic transaction system, an electronic mail transfer method, and a recording medium storing an execution program of the electronic mail transfer method, which can acquire detailed product information while keeping information confidential to a seller.

[0002]

2. Description of the Related Art In recent years, business transactions on the Internet have been actively performed, and an independent virtual store site and a virtual or department store virtual store aggregation site have been opened.

[0003] A terminal user who wishes to purchase a certain product on the Internet (referred to as a "purchaser" in the present specification) searches for a product using a search function of a web browser such as a WWW browser, and searches for the product. By referring to (URL list), a virtual shop site can be accessed.

[0004] A number of virtual stores are linked to the virtual store aggregation site, for example, classified according to the genre of the product to be handled. Can be accessed. Also, in the virtual store aggregation site,
Many provide "e-mail delivery" as a characteristic service. In a typical example of “e-mail distribution”, the user registers his / her own e-mail address, merchandise to be purchased, and the like in the customer management database of the virtual store aggregation site in advance. From the virtual store aggregation site, an e-mail including the URL list of the virtual store site handling the registered product is delivered to the purchaser, and the purchaser refers to this list and sends the e-mail to the appropriate virtual store site. Can be accessed.

[0005] When the purchaser simply accesses the virtual store site, the operator of the virtual store site (referred to as "seller" in this specification) knows the information (mail address) of the purchaser. Never. However, there are cases where the buyer makes an inquiry to the seller about the contents of the product.
Since such an inquiry is usually made by e-mail, the seller of the virtual store site knows the e-mail address of the purchaser.

[0006]

[0005] By the way, the seller,
Once the e-mail address of the purchaser is known, an e-mail such as product information may be delivered to the purchaser against his / her intention. The purchaser is extremely troublesome for the purchaser since one-sided electronic mail of this type, for example, a catalog of a product sample or the like is delivered by electronic mail or the like.

[0007] It can be said that the purchaser is in a weak position in this respect, but a technique for easily solving this has not yet been proposed.

It is an object of the present invention to provide a merchandise electronic transaction system, an electronic mail transfer method, and a recording medium storing an execution program of the electronic mail transfer method, which allow only a specific seller to obtain confidential contact information of a purchaser. To provide.

Another object of the present invention is to allow a management server to manage the transmission and reception of e-mail between a buyer and a seller without letting the seller know the mail address of the buyer. An object of the present invention is to provide a commodity electronic transaction system that does not allow the purchaser's e-mail address to be known, an electronic mail transfer method, and a recording medium storing an execution program of the electronic mail transfer method.

[0010]

The merchandise electronic trading system of the present invention has a first invention in which only a specific seller obtains confidential contact information of a purchaser, and obtains a mail address of the purchaser from the seller. Instead, the management server manages the transmission and reception of e-mail between the purchaser and the seller, so that the second invention prevents the seller from knowing the purchaser's e-mail address.

In the first invention, the equipment of the system operator is:
It has a store registration server, a customer registration server, and a management server. The store registration server has a store database in which store information including seller information and sales product information is registered for a plurality of sellers. Further, the customer server has a customer database in which customer information including, for a plurality of purchasers, purchaser information having contact information as one element and purchase desired product information is registered. The equipment of the system operator is connected to a network such as the Internet, and the seller (seller terminal) and the buyer (purchaser terminal)
Can access each server via the network.

[0012] In the first invention, the management server provides the seller with:
A search for only specific information excluding contact information among purchase desired product information and purchaser information using a customer database is permitted, and confidentiality setting of contact information and cancellation of the confidentiality setting are permitted. At the same time, the management server permits the purchaser to search for the seller information and the sales product information using the store database.

[0013] Further, when the seller sends a request for negotiation with the purchaser including acquisition of contact information, the management server notifies the purchaser of the request, and the management server notifies the purchaser of the request. When there is an approval to release the confidentiality of the contact information (acceptance of the negotiation request), the concealment of the contact information of the seller is released. Here, the presentation of the negotiation is typically an offer to negotiate a commodity price.

In the first invention, the contact information included in the purchaser information can be an electronic mail address or a telephone number of the purchaser.

[0015] In the first invention, the equipment of the system operator is:
It has a web server, and buyers and sellers can access the store registration server, customer registration server, and management server via the web server.

According to the first invention, only the seller who has received the release of confidentiality can acquire the contact information of the buyer. That is, even if the seller presents the product price or the like to the purchaser, the seller cannot always obtain the contact information. Therefore, the buyer does not receive an e-mail from a seller who does not want to negotiate.

Also in the second invention, the equipment of the system operator is:
It has a store registration server, a customer registration server, and a management server. The store registration server has a store database in which store information including seller information and sales product information is registered for a plurality of sellers. Further, the customer registration server has a customer database in which customer information including purchaser information and purchase desired product information is registered for a plurality of purchasers. The management server causes an e-mail to be sent and received between the seller and the purchaser via itself. The equipment of the system operator is connected to a network such as the Internet, and a seller (seller terminal) and a purchaser (purchaser terminal) can access each server via the network.

In the second invention, the management server provides the seller with:
Searching for seller information and sales product information using the store database is permitted. At the same time, when an e-mail from the purchaser to the seller arrives, the e-mail address of the purchaser is kept secret, the e-mail is forwarded to the seller, and an e-mail from the seller to the purchaser is transmitted. When an e-mail arrives, the e-mail is forwarded to the purchaser.

More specifically, the management server can hold a purchaser dummy e-mail address for a purchaser and also hold a seller dummy e-mail address for a seller.

When an e-mail is sent from the purchaser to the purchaser dummy e-mail address of the seller, the management server sets the purchaser dummy e-mail address of the seller to the e-mail address of the seller. Along with the conversion, the e-mail address of the purchaser is converted into a purchaser dummy e-mail address, and the e-mail is transferred to the seller.

On the contrary, when an e-mail is received from the seller to the purchaser's dummy e-mail address, the management server converts the purchaser's dummy e-mail address into the purchaser's e-mail address, The e-mail address of the buyer is converted to a seller dummy e-mail address, and the e-mail is forwarded to the buyer.

In the second invention, the equipment of the system operator also has a web server, and the purchaser and the seller access the store registration server, customer registration server, and management server via the web server. be able to.

In the second invention, it is possible to enable the purchaser to set the secrecy of the e-mail address. here,
The confidentiality setting is a setting to use or not use the buyer dummy e-mail address or the seller dummy address.When the confidentiality setting is set, the e-mail transfer using the dummy e-mail address described above is performed. Do.

When the confidentiality setting is not made, or when the confidentiality setting of the e-mail address is released, when an e-mail addressed to the seller dummy e-mail address arrives from the purchaser, the seller dummy e-mail address is changed. Is converted to the seller's email address, but the buyer's email address is not converted to the buyer's dummy email address. When an e-mail addressed to the purchaser dummy e-mail address arrives from the seller, the purchaser dummy e-mail address is converted to the purchaser's e-mail address. Do not convert to email address.

In the second invention, it is not essential that the seller can search for the purchase desired product information using the customer database. However, the management server provides the seller with the purchase desired product information using the customer database. You can allow search.

In the second invention, when the purchaser information includes information that can identify the purchaser other than the e-mail address, the management server notifies the seller of the purchaser of the purchaser information. A search for information that cannot be specified can be permitted. Here, the “information that can identify the purchaser other than the e-mail address” includes at least one of a name or a name, a telephone number, an address or a location.

The electronic mail transfer method of the present invention can be used, for example, in the second invention, and relates to sending and receiving electronic mail between a plurality of sellers and a plurality of purchasers. In the e-mail transfer method of the present invention, for the seller, the store information including the seller information and the sale product information is registered in the store database, and for the purchaser, the customer information including the purchaser information is registered in the customer database. Is registered, and the transfer of the e-mail is performed using the purchaser dummy e-mail address corresponding to the e-mail address of the purchaser created in advance on a one-to-one basis.

In the e-mail transfer method of the present invention, in the e-mail discrimination step, the received e-mail is an e-mail addressed to the e-mail address of the seller from the purchaser, or a purchaser dummy e-mail from the seller. An electronic mail addressed to the address is determined by referring to a seller list and a purchaser list created in advance.

When the e-mail is an e-mail from the purchaser to the e-mail address of the seller, the e-mail address of the purchaser is replaced with the purchaser dummy e-mail address assigned to the e-mail address. An e-mail address conversion step is performed, and an e-mail transmission step of transmitting the converted e-mail to the seller is performed.

On the other hand, when the e-mail is an e-mail addressed to the purchaser dummy e-mail address from the seller, the purchaser dummy e-mail address is replaced with the purchaser assigned to the purchaser dummy e-mail address. An e-mail address reverse conversion step of reverse conversion to the e-mail address of the e-mail address, and an e-mail transmission step of transmitting the e-mail with the reverse conversion of the address to the purchaser.

The program executed in each of the above steps is:
It can be stored in the storage device of the management server.
