Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a business method and system for exchanging services via an open network such as the Internet and a closed network such as a wireless telephone network.

[0002]

2. Description of the Related Art Recently, many businesses have been conducted on the Internet as electronic commerce. Large B
Various forms have spread from the toB system to auctions among individuals. In these sites, users and product providers can dynamically set prices such as auctions and reverse auctions in which users purchase necessary products such as over-the-counter sales without the intervention of a third party. There is also a business model that collects an intermediary fee by providing a place that can be set. There is also a business model in which not only mere product information but also word-of-mouth information is added to increase the value of information and take an intermediary fee.

A conventional technique is Japanese Patent Application No. 2000-19524.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIG. The whole is large and is composed of an infrastructure provider 100, a service provider 200, and a user terminal 300, and each component is connected to the Internet by a communication infrastructure. The Internet represents an open network and the communication infrastructure represents a closed network. An open network is a network in which the communication protocol on the network and the hardware and software configurations of each device (node) connected to the network are clear. As a typical open network, there is the Internet and a PC having Linux as an OS as a node connected to the Internet. However, the Internet environment is not limited to the above as long as the definition of the open network is met.

The closed network is a network in which the specifications of the communication protocol and the hardware and software of each connected node are not disclosed. For example, a wireless telephone network provided by a Japanese carrier is one example. This is also not limited to the wireless telephone network.

Next, the components of the infrastructure provider will be shown.
As indicated by 100 in FIG. 1, an infrastructure provider has a customer database 101 and provides the functions of a routing function 102, a certification service 103, a service engine distribution function 103, and a gateway service 105. Infrastructure providers carry out infrastructure maintenance, specification of communication means, specification of communication equipment, manufacturing of communication equipment, consignment of the same, etc., usually by billing according to communication volume from subscribers using communication infrastructure. Get a profit. Part of the personal information of subscribed users is stored in the customer database.

The service provider 200 uses the user data 2
03, certificate 204, and service engine 202. As a function, a concrete service 201 is provided. The user data stores the user data registered to use the service. The certificate is a certificate that the infrastructure provider evaluated the service of the service provider. The service engine is a program that describes the protocol necessary for execution, and is provided by the infrastructure provider.

The user terminal is an interface for the user (customer) to enjoy the service provided by this patent, and is specifically a mobile phone, PDA, PC or the like. The user can always control the user terminal, and as long as the function of the terminal allows, the data held can be changed or discarded at any time as desired. In the user terminal, in addition to the input / output unit 301, the service engine 30
3. Personal information 304 is held. Further, the personal information service 302 operates to manage the personal information.

Next, the procedure of the present invention will be outlined with reference to FIG. When conducting business using the business model of the present invention, the service provider first applies to the infrastructure provider 404 for a certificate. According to the infrastructure provider certificate application request, after the examination, the certificate is issued to the service provider at the certification service, and the certificate is passed to the service provider. The examination checks, for example, the financial condition of the service provider and the quality of the service. By receiving the certificate, the service provider can gain the trust of the user by the infrastructure provider. With the acquisition of the certificate,
The service provider receives the service engine from the infrastructure provider at the same time as the certificate.

After the above-mentioned preparation of the service provider, the actual service is started. At the first access, the user performs his user registration 406, 407. The user registration step is omitted in the second and subsequent accesses (40
5). Next, in the certificate confirmation step 409, the service provider is requested to present the certificate. If the certificate is not presented, the normal service is enjoyed (422) and the execution is terminated. If the certificate is presented, it is judged that the service provider of the presentation is credible, and the process proceeds to the next step.

In order to identify the user, the service provider authenticates the user. In the price negotiation step, first, personal information and conditions are exchanged 411. In this step,
Value personal information and negotiate discounts on services equivalent to this value. At this time, the user is required to clearly explain the use range and purpose of use of the personal information, and request permission.

If both parties agree on the conditions, the service provider provides the service and the user receives the service at 412 and 413. As the consideration, the user pays a service fee according to the negotiation content to the service provider (415), and the service provider receives the amount as a service fee (414). This completes the transfer of both services (416, 417). Then 410, 41
If you need to give points based on the condition 1
The service provider gives points at 418 and the user gets points at 419. The acquired point information is stored as user data on the service provider side and as personal information on the user side.

Regarding the communication charge generated in the above series of steps, the communication charge is paid to the infrastructure provider (4
20, 421).

FIG. 8 shows infrastructure providers, service providers,
Shows the flow of charges between users. In FIG. 8A, the service provider pays the certification fee (150) to the infrastructure provider,
Receiving the certificate, the user can use the infrastructure regardless of the service provider Infrastructure fee (151)
Pay. When a user receives a service from a service provider, the service provider pays a service usage fee (152) when using the service. When the user uses the service to disclose the personal information (153) to the service provider, the service provider returns the points (1)
54) is sent. As a modification of the business model of FIG. 8A, FIG. 8B and FIG. 8C can be considered. Figure 8 (b)
Is a business model in which the service provider takes charge of communication required when the user provides personal information and pays on behalf of the user (155). This is not limited to when personal information is provided, but infrastructure usage fees 151 by other users
You may take your place.

FIG. 4 shows details of the flow of the certification service.
First, at the beginning of the certification application processing (404), the service provider creates a certification application designated by the infrastructure provider (450). The certificate describes the content of the service provided by the service provider, the machine environment that provides the service, and the like. This application is sent to the certification service 103 provided by the infrastructure provider in the certification application step 451. The infrastructure provider who received the application form first performs an examination based on the application as a certification service (452). If there is a problem in this examination process (453), the application is rejected and the service provider is notified of this (454). When the application is rejected (455), the service provider determines that the certificate has not been accepted (461) and ends the processing. If the audit is successful, the infrastructure provider presents the contract terms (456). The contract conditions include general contract clauses related to online sales, etc., as well as the setting of the value for personal information such as how much discount or points should be given for user information such as name and address information. In addition, it also includes contract clauses that define user information to be used. In response to this contract condition, the service provider judges whether to accept the contract (457),
If the contract is not accepted, it is considered that the certificate has not been accepted (46
1) Then, the certificate application process ends. In the case of accepting the contract, an acknowledgment is returned (458). In the certified service processing of the infrastructure provider who has received the reply of approval, the service engine suitable for the service environment based on the contract is distributed to the service provider (462). The service engine is, so to speak, a so-called black box for accessing the user's personal information, and also plays a role of guarding the service provider from unauthorized access to the user's personal information. The service provider receiving the service engine at 463 incorporates the service engine into his / her own service, and realizes access and acquisition of user personal information through the service engine.

FIG. 3C is an example of information held by the certificate. Items include company name, company ID, contact information, service level, service environment, security level, and the like. In FIG. 3 (c), the ID of a company called Sakamoto Pharmaceutical is 1
92 indicates that the contact telephone number is 4567890123. The service environment of this company is Wind
The ows (registered trademark) 2000 server is used, and it can be seen that the service level and the security level given by the authorization are both A.

FIG. 3B shows data registered by user registration when the user first accesses the service provided by the service provider. Items include customer ID, point data, and attributes. The customer information is an ID given by the infrastructure provider at the time of user registration. The user accesses the service based on this customer ID.
Personal information disclosed by the user is recorded in the attribute.
In FIG. 3B, 37 points are accumulated for the person with the customer ID 111, and the information that the gender is male, the age is 42 years old, and the occupation is a company employee is disclosed.

FIG. 5 is a diagram showing in detail the processing flow of user authentication and price negotiation. The service 201 provided by the service provider accesses the user's personal information service through the service engine 202. First, the service 201 requests the personal information 500 for user authentication.
At, the personal information is requested from the personal information service (302) of the user terminal. In response to this, the personal information service returns basic personal information (503). This allows
The service provider can authenticate the user.
That is, the user first has to present the minimum information that can be identified by the service provider. Upon receiving the basic personal information (502), the service provider presents items of personal information other than the basic personal information and points (or discount) amount for each item in 504 as price negotiation conditions. When the user presents the personal information, this amount indicates a value as a point or a discount by the service provider and a return such as a discount of the service charge.

FIG. 6 shows an example of a request / reply used by both the service provider and the user in the step of determining the value of personal information. FIG. 6A shows the condition for redeeming personal information and points in the xml format, and the service provider presents this to the user at 504. Note that the xml format is adopted here as an example, and there is no problem with formats other than this format. Customer ID here
In addition to (customer-id), name (nam
e), gender (sex), address (address), age (age), occupation (occupation), hobby (h)
obby), current point value (current-poi)
nt) etc. are included as an xml tag, indicating that the service provider requests the user to present the above information. However, in the above tag, only the customer ID is the value (va
The value of the ID is shown from the service provider side as "lue)". This indicates which user is requested to present the information. In the case of FIG. 6A, the customer ID is 11
It can be seen that the customer is requesting the information presentation of customer 1. This is user data managed by the service provider.
According to the above, it can be seen that it represents the customer data (53) in the first field of the same data. Requested data format of personal information The meanings of the attributes of each tag shown in FIG. 6A are as follows. The request attribute represents a request / non-request regarding the personal information that the tag means,
When the value of the attribute is "yes", it means that the user personal information indicated by the tag is requested. attr
The attribute represents a general attribute of the tag, and when the value is “must”, it indicates that the user must return the personal information represented by the tag. The point attribute represents the value of points that the user can earn when the user returns the personal information indicated by the tag. For example, FIG. 6 (a)
According to the service provider, the condition is "1" when the user replies with the occupation.
Shows to give.

FIG. 6B shows basic personal information returned by the user in response to the basic personal information presentation request sent by the service provider to the user at 500. The basic personal information is information necessary for the service provider to specify the user, and although it is not shown in the figure, it also includes information about authentication. In FIG. 6B, there are a customer ID, a name, a gender, and a current point value as basic personal information, and each value has a customer ID “111”, a name “Akai Akira”, and a gender “
Male ", the current point value is" 37 ".
(C) is detailed point information returned by the user in 509, and items include address, age, and occupation in addition to the basic personal information in FIG. 6 (b). For the address value,
It has "response" as its attribute, and its value is "refuse". This indicates that the user has refused to provide the address information, and thus there is no value corresponding to the address. Regarding the age and occupation, a reply is given, and the values "42" and "employee" are entered respectively.

The user who receives the condition presented by the service provider in 505 considers whether or not to comply with the condition,
If it does not respond, it responds to that effect (508) and immediately enjoys the service (511). In this case, the service will be used without the benefits such as points and discounts.
If the condition is met, the detailed personal information is passed to the service provider (509) and then the service is received (511). After the service ends, the service provider side checks whether or not the personal information is acquired (512), and if the personal information is acquired, the point of the value indicated by the fixed time is given to the user (514). This point is added to the point information data managed by the service provider. On the user side, it is checked in 507 whether the condition is met (5
13), since points can be obtained when the conditions are met, the points are accepted (515). Similarly, the point data is stored as the personal information of the user.

In the above description, it is assumed that information is exchanged between the infrastructure provider, the service provider, and the user by the message exchange means using the network. In the flow of FIG. 5, service provision, exchange of personal information, and exchange of points are realized as separate message exchanges. However, depending on the content of the service, this may have to be expressed as an atomic transaction instead of as a separate transaction. At that time, the message flow may not actually be performed as shown in FIG.

FIG. 7 shows a user interface when the user sets a disclosure condition of personal information. It is possible to set the level of disclosure range for each item of personal information, name, address, sex, occupation, and hobby. In FIG. 7, the disclosure range of the name and the hobby is only for the service provider (55
0,554), gender, occupational disclosure range is optional (552,
553), the address is not disclosed (551). This interface is used when the user sets the disclosure condition for the item of personal information that the service provider wants to acquire to the user at 506. Embodiment of Vending Machine FIG. 9 shows an example in which the present invention is applied to the purchase of goods in a vending machine. The vending machine (602) and the vending machine management server (603) are the Internet (610)
Connected through. The vending machine and the vending machine management server are installed and managed by the service provider (the person who sells the product by the vending machine). The user can access the vending machine from the mobile phone 612, which is a user terminal, through the wireless telephone line (611). Communication between the user terminal and the vending machine is not limited to the wireless telephone line, and Bluetooth or the like, which is short-range wireless communication, may be used.

Web services (604, 605, vending machine) are provided to the user terminal, vending machine, and vending machine management server, respectively.
606) operates and executes a series of purchasing processes while communicating with each other. The negotiation of the purchase price in the purchasing process proceeds basically in the same way as the general price negotiation process. Web service 604 on user terminal
Manages the personal information 304 of the user. The Web service 605 on the vending machine manages the product data 621.
The web service 606 on the management server manages the user data 203.

Next, the actual purchasing operation will be described.
First, the user 600 approaches the vending machine, and accesses the vending machine with the user terminal he / she owns. Access can also be made automatically by simply approaching the vending machine. In addition, the user does not actually carry the user terminal, but instead carries an ID card and inserts the ID card into the vending machine, so that a part of the vending machine can function as a terminal. is there. The program on the vending machine is the Web on the user terminal 601.
Request personal information to the service (604) (6
07). On the other hand, the Web service 604 reads the basic personal information stored in the personal information 304 at the time of user registration and returns the gender and age (608). The vending machine manages the number of sales of products handled in the product data as product data 621 and presents the product sales information to the user (607). FIG. 10 shows a display example of product data. For each product, the total number of sales for the day and the number of sales for the month are shown. For example, a product called carbonated drink C has 201 sales on that day, and the cumulative total of sales for the current month (July) is 1278. Based on such product information,
The user selects a product. Furthermore, it is possible to prepare a button or the like for searching each item information on the Internet. After the user selects the product, the disclosure level of the individual concession is set and the acquisition points are selected by the price determination process. Points can be accumulated and used as a discount when purchasing products.

The points can be used as money in the same manner as the discount when purchasing goods. It can also be effectively used by companies that provide vending machines and their groups. That is, another vending machine of a company belonging to the same group can be used as a substitute for money in the same manner. Further, as another usage method of points, it is possible to use as a hotspot service. This is a service that enables customers to access the Internet by using the fact that it is necessary to access the vending machine management server on the Internet via the vending machine in order to execute the price determination process. . The vending machine and the user terminal are connected by short-range wireless, and the user can connect to the Internet from the user terminal by causing the vending machine to function as a hot spot. Points are used for charging according to the connection time. History Service FIG. 11 is a diagram showing a configuration in which the history service is used as an additional service. The configuration added in addition to the configuration shown in FIG. 1 is shown. A position information receiving device 310, a service information recording unit 311, and history information 312 are added to the user terminal 300. The location information service 110, the history service 111, and the history information 112 are added to the infrastructure provider. The position information receiving device 310 of the user terminal possesses the user terminal, such as a position information service in units of cells or a wireless information service using a satellite in which a part of the service is started, which is performed by a current wireless telephone service company. It is a device that receives a location information service (110) that is a service that identifies the current location of a person. The service information recording device 311 is a device for collecting the enjoyed date, the enjoyed place, and the service content each time the user terminal enjoys the service of the service provider 200, as service information. The history information is data recording the service information collected by the service recording device 311. FIG. 12 shows each item of history information. Items include date and time, place, service provider, and service content. In the first line of this example (80), January 1, 2002
It was recorded that the cold medicine was purchased at 800 yen at Kamari Pharmaceutical in Koenji, Suginami-ku, Tokyo at 12:32 on the 3rd.
Also, from 81 to 85, it can be seen that at 10:20 on January 14, 2002, the curry material was bought at the Yu-Yu store in Ozenji, Kawasaki City, Kanagawa Prefecture.

History service 1 provided by the infrastructure provider
Reference numeral 11 is a service that acts as a proxy for recording service information executed by the user terminal. The user terminal 300 is usually small, and the size of the recordable history information is limited. In order to make up for this and record even a relatively large amount of history information as data of the user terminal, the history information database 112 prepared by the infrastructure provider 100 stores history data of users who have subscribed to the history service. The history information is transferred from the user terminal to the infrastructure provider periodically or when the history information data of the user is full. Collection of the service information is executed by the service information recording device 311 receiving the service content when the points received in 515 of FIG. 5 are stored as personal information, and then the service information recording device displays the date and position information. With history information data 312
To record.

As a development type of personal information based on history information,
It is possible to carry out a pricing process using additional services provided by the infrastructure provider. The user notifies the service provider that the additional service is available when the user is registered with the service provider or when the additional service is subscribed to the infrastructure provider. As a result, the service provider can collect the purchase history from the user's past time to the present as the detailed personal information in the price determination process. That is, it becomes possible to trade with the service provider by using the past purchase history of the user as marketing information.

The charge flow in this business model is shown in FIG. 8 (c). In addition to using the existing infrastructure, users receive history services and location information services as additional services. Therefore, the infrastructure usage fee is paid to the infrastructure provider for the additional service. On the other hand, the service provider gives a larger amount of return to the personal information 158 whose value has been increased by the history service and the location information service. This may be paid back as points, or may be paid back on behalf of the user's infrastructure usage fee or additional service fee.
