Description

The present invention relates to a registration certificate provision system, method, and program.

When conducting a real estate transaction, parties involved, such as the seller of the property, need to refer to the real estate registration details in order to accurately grasp information such as the property's location and owner. For example, Patent Document 1 discloses that the seller should prepare a certified copy of the real estate registry showing the real estate registration details for the land and building. Currently, parties involved in a transaction can apply via the internet to a Legal Affairs Bureau under the jurisdiction of the Ministry of Justice and pay a fee to be issued a certificate of registered details certifying the real estate registration details. However, when there are a large number of properties that may be the subject of a transaction, it becomes necessary to obtain a certificate of registered details for each property, which incurs high fees and places a heavy burden on the parties involved in the transaction.

Japanese Patent Application Laid-Open No. 2002-324173

The present invention is designed to solve the above-mentioned problems and aims to reduce the burden of fees incurred by parties involved in real estate transactions when receiving a certificate of real estate registration details from the Legal Affairs Bureau via a network.

To solve the above problem, a registration certificate provision system according to an embodiment includes a request receiving device, an application device, a delivery device, a receiving device, a database, a providing device, and a billing device. The request receiving device receives a request for the provision of a registration certificate for a property registration desired by the requester from the requester's terminal device via a communications network. In response to accepting the provision request, the application device applies for the issuance of the desired registration certificate to the Legal Affairs Bureau's system via the communications network. In response to the application, the delivery device delivers a fee for the issuance of the desired registration certificate to the Legal Affairs Bureau's system via the communications network. The receiving device receives the desired registration certificate sent from the Legal Affairs Bureau's system via the communications network in response to the application. The database stores data included in the received desired registration certificate. The providing device provides the received desired registration certificate to the requester's terminal device via the communications network. The billing device charges the requester's terminal device a predetermined amount in response to the provision of the desired registration certificate.

Embodiments will be described in detail below with reference to the drawings. Note that, in the drawings, substantially the same components, processes, information, and data will be given the same reference numerals and names. Furthermore, when referring to one of multiple possible components without specifying it, the subscript of the component's reference numeral may be omitted. Furthermore, devices that can be the subject of information processing may be collectively referred to as "nodes."

In addition, the numbers and types of components and data shown in the drawings are illustrative and may be increased, decreased, or changed as appropriate. The order of communication between nodes is also illustrative and may be changed as appropriate. For ease of illustration, some names of components, such as "device" and "system," may be omitted from the drawings as appropriate. In addition, components not related to the essential explanation of the invention may be omitted from the drawings as appropriate.

Figure 1 is a diagram showing the configuration of a real estate service system 1 according to an embodiment. As shown in Figure 1, the real estate service system 1 includes a Legal Affairs Bureau system 2, a real estate information service server 4, a map information server 14, a financial institution server 16, an advertising server 18, and user terminals 30-1 to 30-m, all of which are interconnected via a communication network 100 such as the Internet, allowing for mutual communication. In addition, peripheral devices such as a printer 102 are connected to the real estate information service server 4 as appropriate. Here, m is an integer greater than or equal to 2.

Figure 2 illustrates the configuration of the hardware 12 as computers for the Legal Affairs Bureau system 2, real estate information service server 4, map information server 14, financial institution server 16, advertising server 18, and user terminal 30 shown in Figure 1. As shown in Figure 2, these nodes include a CPU (Central Processing Unit) 122, ROM (Read Only Memory) 124, RAM (Random Access Memory) 126, a network interface (IF) 128 connected to the communication network 100, an input/output device (I/O) 130 to which user interface (UI) devices such as a display and keyboard are connected, a recording device 132 that writes and reads data to and from recording media such as flash memory and DVDs, and an external device IF 134 to which a printer 102 or the like is connected.

The components of the real estate service system 1 may be realized by specialized hardware, by the CPU 122 executing software stored in the ROM 124 shown in Figure 2, or by a combination of hardware and software.

In the real estate service system 1 shown in Figure 1, the Legal Affairs Bureau system 2 is operated by the Legal Affairs Bureau and issues a certificate of real estate registration details to the real estate information service server 4. In other words, the Legal Affairs Bureau system 2 communicates with the real estate information service server 4 via the communication network 100 and receives an application for the issuance of a certificate of real estate registration details from the real estate information service server 4.

When the Legal Affairs Bureau System 2 receives an application for issuance, it issues a certificate of registered matters to the real estate information service server 4 and receives payment of a fee from the real estate information service server 4. However, the Legal Affairs Bureau System 2 can also communicate directly with the user terminal 30 via the communication network 100, without going through the real estate information service server 4, to accept an application for issuance of a certificate of registered matters, issue the certificate of registered matters, and receive payment of a fee.

Note that hereinafter, the real estate registration certificate and its electronic data will also be referred to simply as the registration certificate and certificate. Furthermore, the series of operations from the real estate information service server 4 applying for the issuance of the registration certificate to the Legal Affairs Bureau system 2, the issuance of the registration certificate from the Legal Affairs Bureau system 2 to the real estate information service server 4, and the payment of the fee from the real estate information service server 4 to the Legal Affairs Bureau system 2 will also be referred to simply as the acquisition of the registration certificate.

Figure 3A is a diagram illustrating the data contained in a land registration certificate. Figure 3B is a diagram illustrating the data contained in a detached building registration certificate. Figure 3C is a diagram illustrating the data contained in a condominium registration certificate.

As shown in Figures 3A-3C, the certificates of real estate registration for land, detached buildings, and apartment buildings contain data corresponding to the items contained in the certified copies of real estate registries for those properties. That is, these certificates of real estate registration contain data identifying the real estate, its location, the owner's name, and the owner's address or location. These certificates of real estate registration also contain data that can be used to estimate the transaction price of the real estate, such as the date of registration acceptance, the amount of the claim, and interest.

Furthermore, as shown in Figure 3B, the building registration certificate further includes a title section indicating the attached building.Furthermore, as shown in Figure 3C, the apartment building registration certificate further includes the house number of the exclusive portion.

As shown in Figure 3A, the title section of a land registration certificate (land description) includes data indicating the real estate number, location, parcel number, land use, land area, reason and date of registration, and owner. Owner data indicating the owner includes data indicating the name or title of the real estate owner and address or residence. As shown in Figure 3B, the title section of a building registration certificate (main building description) includes data indicating the location, house number, type, structure, floor area, and date of registration.

As shown in Figure 3C, the title section of a certificate of registered details for a condominium (showing the building) includes data such as the location map number, location, building name, structure, floor area, reason for registration, and date.

In addition, the title section of a condominium registration certificate (displaying the building of the exclusive use portion) includes data indicating the real estate number, house number, building name, type, structure, floor area, reason for registration, and date. In addition, the title section of a condominium registration certificate (displaying the land right) includes data indicating the land code, type of land right, percentage of the land right, reason for registration, date, and owner.

As shown in Figures 3A to 3C, Section A of the title section of the certificate of registration of land, buildings, and condominiums contains data indicating the owner associated with one or more ranking numbers, the purpose of the registration, the date and number of receipt, the right holder, and other details.

Section B of the title section of a land registration certificate contains data indicating the purpose of registration associated with one or more ranking numbers, the date of registration and its registration number, the owner of the right, and other details. The data indicating the owner of the right, etc. in Section B of the title section includes data indicating the cause of registration, the amount of the claim, interest, the amount of damages, the debtor, mortgagee, and joint collateral. The data on joint collateral indicates a list of joint collateral.

The map information server 14 shown in Figure 1 is operated by a provider of Internet-related services, and in response to inquiries from other nodes, provides map information on a web page that shows the requested property, as well as surrounding properties and maps.

The financial institution server 16 is operated by, for example, a bank or credit card company, and processes the transfer of money between the Legal Affairs Bureau System 2, the real estate information service server 4, and the user terminal 30. In other words, when the financial institution server 16 receives an instruction from the real estate information service server 4 to pay a fee to the Legal Affairs Bureau System 2, it transfers the amount of the fee from the account of the real estate information service server 4 to the account of the Legal Affairs Bureau System 2.

In addition, when the financial institution server 16 receives an instruction from the user terminal 30 to pay the charge to the real estate information service server 4, it performs a process to transfer the amount of the charge from the user's account on the user terminal 30 to the account on the real estate information service server 4.

However, the payment of fees from the real estate information service server 4 to the Legal Affairs Bureau system 2 and the payment of charges from the user terminal 30 to the real estate information service server 4 do not need to be made via the financial institution server 16. In other words, the payment of fees may be made directly between the Legal Affairs Bureau system 2 and the real estate information service server 4, and the payment of charges may be made directly between the user terminal 30 and the real estate information service server 4. In addition, the transfer of money between accounts is also referred to as a transfer.

The advertising server 18 is operated by parties involved in real estate transactions, such as sellers and brokers, and provides advertising information for the requested property and surrounding properties on a web page in response to inquiries from other nodes.

Figure 4 is a diagram illustrating the configuration of the user terminal 30 shown in Figure 1. As shown in Figure 4, the user terminal 30 includes a request/receive control device 300, a registration device 302, an authentication device 304, a request device 306, a payment device 308, and a receiving device 310.

The user terminal 30 uses these components to register the user of the user terminal 30 with the real estate information service server 4. The user terminal 30 also receives a certificate of registered matters from the real estate information service server 4 via the communication network 100. The user terminal 30 also pays money in accordance with the charges made by the real estate information service server 4 via the communication network 100.

In the following, the series of operations including the request for a registration certificate from the user terminal 30 to the real estate information service server 4, the transmission of the registration certificate from the real estate information service server 4 to the user terminal 30, the billing from the real estate information service server 4 to the user terminal 30, and the payment of money from the user terminal 30 to the real estate information service server 4 will also be referred to as providing the registration certificate.

The request/reception control device 300 controls the components of the user terminal 30 to process the provision of a registration certificate to the real estate information service server 4. The request/reception control device 300 also controls communications between the user terminal 30 and other nodes via the communication network 100.

The registration device 302 performs the processing necessary to register the user of the user terminal 30 with the real estate information service server 4. In other words, the registration device 302 communicates with the real estate information service server 4, creates an account for the user on the real estate information service server 4, and sets authentication information such as identification information (ID; IDentifier) and password.

The registration device 302 also sets a user type indicating whether the user is a buyer, seller, or broker among the parties involved in the real estate transaction. Note that users do not have to be uniquely classified as buyers, sellers, or brokers; a seller may also be a buyer, or a seller may also be a broker.

The registration device 302 also sets the user's rank on the real estate information service server 4, that is, sets the user rank indicating whether the user is a paid or free member of the real estate information service server 4, whether the user is a continuous or temporary user, etc. The registration device 302 also sets the user name indicating the user's name, location indicating the user's address or whereabouts, and contact information indicating the user's email address, telephone number, etc.

The authentication device 304 performs the authentication process required when a user of a user terminal 30 who has created an account on the real estate information service server 4 logs in to the real estate information service server 4. This authentication can be achieved by various methods, such as authentication using an ID and password, or authentication using biometric information such as a fingerprint. Note that hereinafter, a user of a user terminal 30 who has created an account on the real estate information service server 4 will also be referred to simply as a user.

The requesting device 306, for example, displays a GUI (Graphical User Interface) image on the display of the UI device of the user terminal 30. Furthermore, the requesting device 306 requests a certificate of registered matters and accepts information identifying the certificate of registered matters in response to user operation on the keyboard or other device of the UI device of the user terminal 30 that is the requesting source. Furthermore, the requesting device 306 requests the real estate information service server 4 to provide the certificate of registered matters identified by the accepted information.

The payment device 308 receives the charge from the real estate information service server 4 and pays the charged amount to the real estate information service server 4 via the financial institution server 16.

The receiving device 310 receives the registration certificate sent from the real estate information service server 4 and displays it on a display and records it on a recording medium.

Figure 5 is a diagram showing the configuration of the real estate information service server 4 shown in Figure 1. As shown in Figure 5, the real estate information service server 4 includes a certificate database (DB) 40, a certificate provision service system 42, a certificate acquisition system 52, and a distribution promotion system 6 that uses a printer 102 to print direct mail (DM) soliciting real estate transactions.

The real estate information service server 4 is operated, for example, by a real estate agent or a provider of an internet real estate transaction platform. The operator of the real estate information service server 4 may conduct real estate transactions themselves, or may not conduct real estate transactions themselves, and may only provide real estate information or only provide agents suitable for real estate transactions.

Using these components, the real estate information service server 4 applies to the Legal Affairs Bureau system 2 for the issuance of a registration certificate, and receives the registration certificate issued by the Legal Affairs Bureau system 2 in response to this application. The real estate information service server 4 also stores the received registration certificate in multiple entries of certificate information stored in the certificate DB 40.

The certificate information may be the registration certificate itself, the registration certificate plus additional information such as an ID, or a portion of the registration certificate that is required for processing by the real estate information service server 4.

The real estate information service server 4 also transmits the received registration certificate to the user terminal 30 that requested it. In addition, in response to a request for payment of the fee from the Legal Affairs Bureau system 2, the real estate information service server 4 pays the fee amount to the Legal Affairs Bureau system 2 via the financial institution server 16.

In the following, the series of operations including the application for issuance of a certificate of registered matters from the real estate information service server 4 to the Legal Affairs Bureau system 2, the request for payment of a fee from the Legal Affairs Bureau system 2 to the real estate information service server 4, and the payment of the fee from the real estate information service server 4 to the Legal Affairs Bureau system 2 will also be referred to as obtaining a certificate of registered matters.

The real estate information service server 4 also bills the user terminal 30. The real estate information service server 4 also uses the certificate information stored in the certificate DB 40 to provide various services to promote real estate distribution, such as soliciting real estate sales, to parties involved in real estate transactions. Therefore, with these functions, the real estate information service server 4 can become a platform that provides useful information to parties involved in real estate transactions.

Figure 6 is a diagram showing the configuration of the certificate provision service system 42 shown in Figure 5. As shown in Figure 6, the certificate provision service system 42 includes a certificate provision unit 44, a user DB 46 that stores user information, an accounting DB 48 that stores payment information indicating payment of fees to the Legal Affairs Bureau system 2 and billing information indicating charges to the user, and a certificate acquisition unit 50.

The certificate provision service system 42 uses these components to create and manage accounts for users of the user terminal 30, provide registration certificates to the user terminal 30, and obtain registration certificates from the Legal Affairs Bureau system 2.

The certificate providing unit 44 comprises a provision control device 440, a user registration device 442, a user authentication device 444, a user billing device 446, a user request receiving device 448, and a certificate providing device 450. Using these components, the certificate providing unit 44 creates and manages user accounts, and provides registration certificates to the Legal Affairs Bureau system 2.

The provision control device 440 controls the other components of the certificate provision unit 44 to provide registration certificates to the user terminal 30 and perform the associated billing process. The provision control device 440 also controls communications between the certificate provision unit 44 and other nodes via the communication network 100.

The user registration device 442 processes user registration data from the user terminal 30, creates user accounts, and stores user information that manages the created accounts in the user DB 46.

The user authentication device 444 authenticates the user using user information stored in the user DB 46 and data indicating the ID, password, etc. from the user terminal 30. The certificate providing unit 44 further stores the results of this authentication in the user DB 46.

When providing a registration certificate in response to a request from the user terminal 30, the user billing device 446 charges the user, receives payment for the charge from the user via the financial institution server 16, and stores billing information indicating the charge and the results in the accounting DB 48. The user billing device 446 also bills paid members for membership fees, receives payment of the membership fees, and stores membership fee information indicating whether or not the membership fee has been paid in the user DB 46.

Figure 7 is a diagram illustrating user information stored in the user DB 46 shown in Figure 6. As shown in Figure 7, the multiple entries included in the information stored in the user DB 46 include data indicating an account ID that uniquely identifies the user's account, a user ID that uniquely identifies one of the users, a user type, a user rank, authentication information such as an ID and password, a user name that indicates the user's name or title, a location that indicates the user's address or residence, contact information such as the user's email address and telephone number, membership fee information that indicates whether the user has paid for the membership, real estate, real estate prices, and authentication result information that indicates whether the user has been authenticated or not.

Data indicating real estate is set by the user at any time and indicates real estate that the user is interested in, such as a transaction they wish to make. The asking price indicates the asking price, such as the selling price or buying price, in a transaction for real estate that the user is interested in. Note that one entry of user information may include data indicating multiple properties and their asking prices. Also, hereinafter, "user information entry" may be omitted from the word "entry" and simply referred to as "user information."

Figure 8A is a diagram illustrating billing information stored in the accounting DB 48 shown in Figure 6. As shown in Figure 8A, multiple entries of the billing information store a user ID that is common to the user information shown in Figure 7, data indicating the registration certificate provided to this user, data indicating the amount of the charge, and billing detail information that includes data indicating whether the charge has been paid or is unpaid, all in association with each other.

The user request receiving device 448 shown in Figure 6 receives a request for the provision of a registration certificate from the user terminal 30 and notifies the user billing device 446 of this request. The user request receiving device 448 also outputs information included in this request that identifies the registration certificate requested by the user to the certificate acquisition unit 50.

The certificate providing device 450 receives the registration certificate issued by the Legal Affairs Bureau system 2 from the certificate acquisition unit 50 and provides it to the user terminal 30 that requested it. The certificate providing device 450 also notifies the user billing device 446 that the registration certificate has been provided to the user terminal 30.

As shown in FIG. 6, the certificate acquisition unit 50 includes an acquisition control device 500, a certificate application device 502, a certificate receiving device 504, and a fee payment device 506. Using these components, the certificate acquisition unit 50 acquires, from the Legal Affairs Bureau system 2, a registration certificate to be provided to the user terminal 30.

The acquisition control device 500 controls the components of the certificate acquisition unit 50 to acquire a registration certificate from the Legal Affairs Bureau system 2 and process the associated fees. The acquisition control device 500 also controls communications between the certificate acquisition unit 50 and other nodes via the communication network 100.

The certificate application device 502 receives information identifying the registration certificate requested by the user from the certificate providing unit 44, and applies to the Legal Affairs Bureau system 2 for the issuance of the registration certificate identified by this information.

The certificate receiving device 504 receives the registration certificate issued from the Legal Affairs Bureau system 2 in response to an application for issuance, and outputs it to the certificate providing unit 44.

The fee payment device 506 pays the fee via the financial institution server 16 in response to a fee payment instruction from the Legal Affairs Bureau system 2, and stores payment information indicating the payment result in the accounting DB 48.

Figure 8B is a diagram illustrating payment information stored in the accounting DB 48 shown in Figure 6. As shown in Figure 8B, the payment information stores the registration certificate for which payment of the fee is instructed, the payment amount, and data indicating whether the fee has been paid or not, in association with each other.

In addition, since there may be multiple financial institution servers 16 in the real estate service system 1, payment information must be created for each of the multiple financial institution servers 16. Therefore, in this case, the payment information includes multiple entries, and each of the multiple entries is assigned a financial institution server ID that indicates the ID of one of the multiple financial institution servers 16.

Figure 9 is a diagram showing the configuration of the certificate acquisition system 52 shown in Figure 5. As shown in Figure 9, the certificate acquisition system 52 includes, in common with the certificate acquisition unit 50, the acquisition control device 500, the certificate application device 502, the certificate receiving device 504, and the fee payment device 506, all of which are components of the certificate provision service system 42 shown in Figure 6. Using these components, the certificate acquisition system 52 acquires a registration certificate from the Legal Affairs Bureau system 2 in response to an operation by the operator of the real estate information service server 4 or in response to a request from the distribution promotion system 6, and stores it in the certificate DB 40 as certificate information.

Figure 10 is a diagram showing the configuration of the distribution promotion system 6 shown in Figure 5. As shown in Figure 10, the distribution promotion system 6 comprises a distribution promotion information creation device 60 and a service provision device 62. The distribution promotion information creation device 60 comprises a real estate information creation device 600, a real estate information collection device 602, a price estimation device 604, a real estate DB 606, a distribution promotion information creation device 608, and a distribution promotion DB 610. The service provision device 62 comprises a seller solicitation device 620, a buyer solicitation device 622, an information presentation device 624, and an introduction device 626 as service provision processing devices.

The distribution promotion system 6 uses these components to read certificate information indicating the registration certificates shown in Figures 3A to 3C from multiple entries in the certificate DB 40 shown in Figure 5. The distribution promotion system 6 processes the read certificate information and provides services to promote real estate distribution, such as soliciting real estate sellers and buyers, presenting real estate information, and introducing brokerage agents.

The real estate information creation device 600 of the distribution promotion information creation device 60 reads and analyzes certificate information from the certificate DB 40 to obtain data identifying the registration certificate, such as the location data contained in the registration certificate shown in Figures 3A to 3C. The real estate information creation device 600 outputs the obtained data to the personal property information collection device 602, which then collects the real estate registration certificate.

The real estate information creation device 600 also creates a real estate ID that uniquely identifies one of multiple properties from the certificate information read from the certificate DB 40 and the certificate information from the real estate information collection device 602. The real estate information creation device 600 associates the real estate ID with the registration certificate indicated by the certificate information, creates a real estate information entry, outputs it to the real estate DB 606, and stores it sequentially. Note that the real estate ID may uniquely identify the real estate registration certificate itself, rather than the real estate.

Figure 11A is a diagram illustrating real estate information stored in real estate DB 606. As shown in Figure 11A, the real estate information includes multiple entries. These multiple entries store, in association with each other, a real estate ID uniquely assigned to the real estate, the real estate registration certificate, an estimated price estimated as the transaction price when the real estate is traded, and data indicating the desired price included in the user information of a user who has some interest in the real estate. Note that real estate IDs are assigned regardless of whether the owner of the real estate is a user who has an account on real estate information service server 4.

The real estate information collection device 602 transmits data indicating the location of the property from the real estate information creation device 600 to the map information server 14 shown in FIG. 1, and receives map information including this location. The real estate information collection device 602 also uses a search engine provided on the communication network 100 to perform a search using the data indicating the location of the property from the real estate information creation device 600. When the results of this search indicate an advertisement from the advertising server 18, the real estate information collection device 602 uses the search results to obtain real estate advertising information from the advertising server 18.

The real estate information collection device 602 also collects information about real estate properties surrounding the real estate input from the real estate information creation device 600 from the map information obtained from the map information server 14 and the advertising information obtained from the advertising server 18. The real estate information collection device 602 reads certificate information indicating the registration certificate identified by the collected real estate information from the certificate DB 40 shown in Figure 5.

Alternatively, the real estate information collection device 602 causes the certificate acquisition system 52 to acquire a registration certificate identified by the collected real estate information, and reads it as certificate information via the certificate DB 40. The real estate information collection device 602 outputs the read certificate information to the real estate information creation device 600.

In addition, when the location of land is input from the real estate information creation device 600 and this location indicates a large city, the real estate information collection device 602 determines that land that shares the same prefecture, city, ward, town, and address as this land is real estate surrounding this real estate.

Furthermore, when using map information, the real estate information collection device 602 determines that land that faces a common route with the land and is within a predetermined distance from the land is real estate surrounding the real estate.Furthermore, when the location of the real estate indicates one of multiple exclusive parts included in an apartment building, the real estate information collection device 602 determines that other exclusive parts that share a building with this exclusive part are real estate surrounding the real estate.

The price estimation device 604 estimates the transaction price at the time of real estate trading from the data indicating the receipt date, receipt number, claim amount, and interest, which are included in the data indicating the right holder and others in the registration certificate shown in Figures 3A to 3C, and calculates the estimated price. The price estimation device 604 also adds the data indicating the estimated price to the real estate information stored in the real estate DB 606, as shown in Figure 11A.

The price estimation device 604 estimates the amount of the debt plus interest, for example, based on data indicating the debt amount and interest, the date indicated by the receipt date and receipt number, and the date on which the transaction price is estimated. The price estimation device 604 also estimates the total amount of the debt plus interest and the down payment plus interest, based on the typical ratio between down payments and loans when purchasing real estate. The price estimation device 604 then estimates the transaction price of the real estate by taking into account this total amount and any changes in the transaction price of the real estate from the date indicated by the receipt date and receipt number to the date on which the transaction price is estimated.

The distribution promotion information creation device 608 is a service information creation device that creates service information for providing services based on real estate information stored in the real estate DB 606 and user information stored in the user DB 46 of the certificate provision service system 42 shown in Figure 6. The distribution promotion information creation device 608 stores the created service provision information in the distribution promotion DB 610 as distribution promotion information. The distribution promotion information is used for soliciting real estate sellers and buyers, presenting real estate information, introducing real estate agents, etc.

Recruiting sellers of real estate involves, for example, soliciting real estate owners to sell their real estate and soliciting real estate creditors to sell their shares of debt using electronic data transmitted via communications network 100 and direct mail printed by printer 102. Sellers can be solicited from unspecified real estate owners and creditors.

In other words, real estate sellers can be solicited from people and companies who are determined to be the owner and creditors of the real estate in the registration certificate included in the real estate information shown in Figure 11A, regardless of whether they are users with accounts on the real estate information service server 4. Below, we will explain the case where sellers are solicited from the owner of the real estate.

In addition, soliciting buyers for real estate involves, for example, soliciting users registered on the real estate information service server 4 who are indicated as buyers by the user type in the user information shown in Figure 7 to purchase real estate owned by users who are indicated as sellers, by means of direct mail, e-mail, etc.

Providing real estate information also involves, for example, presenting the user with a certificate of registration of the property that has been put up for sale and the seller's asking price or estimated price via email and electronic data.

Real estate agent introduction involves selecting an agent suitable for brokering a property that has been put up for sale from among users who have been indicated as agents by the user type in their user information, and introducing the agent to the user who wishes to purchase the property that has been put up for sale.

Users who can receive real estate information and agent referral services can be selected as appropriate based on the management policy of the operator of the real estate information service server 4. In other words, the operator of the real estate information service server 4 can, for example, provide real estate information and agent referrals only to users whose user rank included in the user information indicates that they are paid members, or to all users regardless of whether they are paid or free members.

Figure 11B is a diagram illustrating distribution promotion information stored in the distribution promotion DB 610 shown in Figure 10. The distribution promotion information includes multiple entries, and as shown in Figure 11B, the multiple entries store data in association with one or more of the following: a distribution promotion service ID, a real estate ID, a service type, an estimated price of the real estate estimated by the price estimation device 604, a desired price, and a destination ID indicating the destination to which the service will be provided.

The distribution promotion service ID uniquely identifies the service provided by the service providing device 62. The real estate ID uniquely identifies the real estate that is the subject of the service identified by the distribution promotion service ID.

The service type is service type data that indicates one of several types of services that can be provided in relation to the real estate indicated by the real estate ID in order to promote real estate distribution, i.e., soliciting real estate sellers and buyers, presenting real estate information, and introducing real estate agents. One or more recipient IDs are recipient data that indicate the owner or user of the real estate receiving the service. Note that the owner of the real estate receiving the service may or may not be a user with an account on the real estate information service server 4. Furthermore, if the owner of the real estate receiving the service is not a user with an account on the real estate information service server 4, the recipient ID can be created regardless of the owner's wishes.

The distribution promotion information, by combining these pieces of data, indicates which of the services for promoting real estate distribution indicated by the service type will be provided to the owner or user of the real estate indicated by the recipient ID for the real estate indicated by the real estate ID.

The operation of the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626 will be described in detail below with reference to Figures 12A to 12C. The seller soliciting device 620 shown in Figure 10 processes distribution promotion information and user information, and performs processing to solicit sellers. Figure 12A is a flowchart showing the processing by which the seller soliciting device 620 solicits sellers as a service to promote the distribution of real estate.

As shown in FIG. 12A, in step S100, the seller recruitment device 620 reads distribution promotion information from the distribution promotion DB 610.

In step S102, the seller solicitation device 620 determines whether the service type in the distribution promotion information indicates a seller solicitation. If the service type in the distribution promotion information indicates a seller solicitation (Y in S102), the seller solicitation device 620 proceeds to S104; if the service type in the distribution promotion information does not indicate a seller solicitation (N in S102), the seller solicitation device 620 terminates the process.

In step S104, the seller recruitment device 620 reads all of the user IDs included in the user information shown in Figure 7 from the user DB 46 shown in Figure 6.

In step S106, the seller recruitment device 620 reads the recipient IDs of distribution promotion information that has not yet been processed.

In step S108, the seller soliciting device 620 determines whether the destination ID read in the process of S106 is included in the user ID read in the process of S104. If the read destination ID is included in the user ID (Y in the process of S108), the seller soliciting device 620 proceeds to process S110, and if the read destination ID is not included in the user ID (N in the process of S108), the seller soliciting device 620 proceeds to process S114.

In step S110, the seller solicitation device 620 reads an entry containing a user ID that is the same as the destination ID from the user information stored in the user DB 46. The seller solicitation device 620 further determines whether or not it can provide seller solicitation services to a user assigned a user ID that is the same as the destination ID, based on the user class and membership information stored in the read user information entry.

If the seller solicitation device 620 can provide seller solicitation services (Y in S110), it proceeds to S112; if it cannot provide seller solicitation services (N in S110), it proceeds to S122.

In step S112, the seller recruitment device 620 obtains data indicating the user's name or title and contact information from the user information entry read in the processing of S110.

In step S114, the seller solicitation device 620 reads real estate information from the real estate DB 606 that includes a real estate ID that is the same as the real estate ID included in the distribution promotion information.

In step S116, the seller solicitation device 620 obtains data indicating the property owner from the registration certificate included in the property information read in processing S114, and creates contact information for the property owner from this data.

In step S118, if the seller solicitation device 620 obtains the name or title of the property owner and their address in the processing of S112 or S116, it causes the printer 102 to print a direct mail message to be sent to the property owner and solicits sellers.

Alternatively, when the property owner's email address or other information is obtained in the processing of S112, the seller solicitation device 620 transmits electronic data for soliciting sellers to the property owner's terminal device via the communication network 100. Note that in the processing of S118, the property owner's terminal device may be a user terminal 30, as described above, or a terminal device other than a user terminal 30 of a person who does not have an account on the real estate information service server 4. Furthermore, when soliciting sellers, the property owner may be invited to create an account on the real estate information service server 4.

In step S120, the seller soliciting device 620 determines whether the processes of S106 and S108 have been performed for all of the recipient IDs included in the distribution promotion information, that is, whether processing has been completed for all of the recipient IDs included in the distribution promotion information. If processing has been completed for all of the recipient IDs (Y in S120), the seller soliciting device 620 proceeds to processing S122, and if processing has not been completed for all of the recipient IDs (N in S120), it returns to processing S106.

In step S122, the seller recruitment device 620 deletes the distribution promotion information entry used in the seller recruitment process and terminates processing.

The buyer soliciting device 622 processes distribution promotion information and user information, and performs processing to solicit buyers. The processing of the buyer soliciting device 622 will be further explained below with reference to Figure 12B. Figure 12B is a flowchart showing the processing by which the buyer soliciting device 622 solicits buyers as a service to promote the distribution of real estate.

As shown in FIG. 12B, in step S140, the buyer solicitation device 622 reads distribution promotion information from the distribution promotion DB 610.

In step S142, the buyer solicitation device 622 determines whether the service type in the distribution promotion information indicates a buyer solicitation. If the service type in the distribution promotion information indicates a buyer solicitation (Y in S142), the buyer solicitation device 622 proceeds to S144; if the service type in the distribution promotion information does not indicate a buyer solicitation (N in S142), the buyer solicitation device 622 terminates the process.

In step S144, the buyer solicitation device 622 reads all of the user IDs included in the user information shown in Figure 7 from the user DB 46 shown in Figure 6.

In step S146, the buyer solicitation device 622 reads the recipient IDs of distribution promotion information that has not yet been processed.

In step S148, the buyer soliciting device 622 determines whether the destination ID read in the processing of S146 is included in the user ID read in the processing of S144. If the read destination ID is included in the user ID (Y in processing of S148), the buyer soliciting device 622 proceeds to processing of S150, and if the read destination ID is not included in the user ID (N in processing of S148), the buyer soliciting device 622 proceeds to processing of S156.

In step S150, the buyer solicitation device 622 reads an entry containing a user ID that is the same as the destination ID from the user information stored in the user DB 46. The buyer solicitation device 622 further determines whether or not it can provide a buyer solicitation service to a user assigned a user ID that is the same as the destination ID, based on the user class and membership information stored in the read user information entry.

If the buyer solicitation device 622 can provide buyer solicitation services (Y in S150), it proceeds to S152; if it cannot provide buyer solicitation services (N in S150), it proceeds to S156.

In step S152, the buyer solicitation device 622 obtains data indicating the user's name or title and their contact information from the user information entry read in the processing of S150.

In step S154, if the buyer solicitation device 622 obtains the user's name or title and address, etc., in the processing of S152, it causes the printer 102 to print a direct mail message to be sent to users who may be potential buyers of the property, and solicits buyers.

Alternatively, when the user's email address or other information is obtained in the processing of S152, the buyer solicitation device 622 transmits electronic data for soliciting buyers via the communication network 100 to the user terminal 30 of the user who is a potential buyer of the real estate.

In step S156, the buyer solicitation device 622 determines whether the processes of steps S146 and S148 have been performed for all of the recipient IDs included in the distribution promotion information, i.e., whether processing has been completed for all of the recipient IDs included in the distribution promotion information.

When the buyer solicitation device 622 has completed processing for all of the destination IDs (Y in S156), it proceeds to S158, and when the buyer solicitation device 622 has not completed processing for all of the destination IDs (N in S156), it returns to S146.

In step S158, the buyer solicitation device 622 deletes the distribution promotion information entry used in the buyer solicitation process and terminates processing.

The information presentation device 624 processes the distribution promotion information and user information, and performs processing to provide information. The processing of the information presentation device 624 will be further explained below with reference to Figure 12C. Figure 12C is a flowchart showing the processing by which the information presentation device 624 provides information as a service to promote the distribution of real estate.

As shown in FIG. 12C, in step S180, the information presentation device 624 reads distribution promotion information from the distribution promotion DB 610.

In step S182, the information presentation device 624 determines whether the service type in the distribution promotion information indicates information provision. If the service type in the distribution promotion information indicates information provision (Y in S182), the information presentation device 624 proceeds to S184; if the service type in the distribution promotion information does not indicate information provision (N in S182), the information presentation device 624 terminates the process.

In step S184, the information presentation device 624 reads all of the user IDs included in the user information shown in Figure 7 from the user DB 46 shown in Figure 6.

In step S186, the information presentation device 624 reads the recipient ID of the distribution promotion information that has not yet been processed.

In step S188, the information presentation device 624 determines whether the destination ID read in the processing of S186 is included in the user ID read in the processing of S184. If the read destination ID is included in the user ID (Y in processing of S188), the information presentation device 624 proceeds to processing of S190, and if the read destination ID is not included in the user ID (N in processing of S188), the information presentation device 624 proceeds to processing of S196.

In step S190, the information presentation device 624 reads an entry containing a user ID that is the same as the destination ID from the user information stored in the user DB 46. The information presentation device 624 further determines whether or not it is possible to provide information to a user with a user ID that is the same as the destination ID, based on the user class and membership information stored in the read user information entry.

If the information presentation device 624 can provide information (Y in S190), it proceeds to S192; if it cannot provide information (N in S190), it proceeds to S196.

In step S192, the information presentation device 624 obtains data indicating the user's name or title and their contact information from the user information entry read in the processing of S190.

In step S194, if the user's name or title and address, etc. are obtained in the processing of S192, the information presentation device 624 causes the printer 102 to print a document containing all or an excerpt of the registration certificate to be sent to the user to whom the information is to be provided, and further causes the printer 102 to print information indicating the destination of this document on an envelope.

Alternatively, when the user's email address or other information is obtained in the processing of S192, the information presentation device 624 provides the information to the user by transmitting the entire certificate of registered matters or an excerpted portion thereof, and electronic data indicating the estimated price of the property, to the user terminal 30 via the communications network 100.

The user to whom the information is provided may also be provided with the estimated price and desired price of the property. Furthermore, upon receiving the information, the user can store the data indicating the non-operation and desired price shown in Figure 7 in the user DB 46 via the user terminal 30.

In step S196, the information presentation device 624 determines whether the processes of steps S186 and S188 have been performed for all recipient IDs included in the distribution promotion information, i.e., whether processing has been completed for all recipient IDs included in the distribution promotion information.

When processing has been completed for all destination IDs (Y in S196), the information presentation device 624 proceeds to processing S198; when processing has not been completed for all destination IDs (N in S196), the information presentation device 624 returns to processing S186.

In step S198, the information presentation device 624 deletes the distribution promotion information entry used in the information provision process and terminates the process.

The introduction device 626 processes distribution promotion information and user information, and performs processing for introducing agents. The processing of the introduction device 626 will be further explained below with reference to Figure 12D. Figure 12D is a flowchart showing the processing by which the introduction device 626 introduces agents as a service for promoting the distribution of real estate.

As shown in FIG. 12D, in step S220, the introduction device 626 reads distribution promotion information from the distribution promotion DB 610.

In step S222, the introduction device 626 determines whether the service type in the distribution promotion information indicates an introduction by an intermediary. If the service type in the distribution promotion information indicates an introduction by an intermediary (Y in S222), the introduction device 626 proceeds to processing S224; if the service type in the distribution promotion information does not indicate an introduction by an intermediary (N in S222), the introduction device 626 terminates processing.

In step S224, the introduction device 626 reads all of the user IDs included in the user information shown in Figure 7 from the user DB 46 shown in Figure 6.

In step S226, the introduction device 626 reads out the distribution promotion information provider ID that will be introduced to an intermediary that has not yet been processed.

In step S228, the introduction device 626 determines whether the destination ID read in the processing of S226 is included in the user ID read in the processing of S224. If the read destination ID is included in the user ID (Y in processing of S228), the introduction device 626 proceeds to processing of S230, and if the read destination ID is not included in the user ID (N in processing of S228), the introduction device 626 proceeds to processing of S238.

In step S230, the introduction device 626 reads an entry containing a user ID that is the same as the destination ID from the user information stored in the user DB 46. The introduction device 626 further determines, based on the user class and membership information stored in the read user information entry, whether or not it is possible to provide an intermediary introduction service to the user assigned the user ID that is the same as the destination ID.

If the introduction device 626 can provide the intermediary introduction service (Y in S230), it proceeds to S232; if it cannot provide the intermediary introduction service (N in S230), it proceeds to S238.

In step S232, the introduction device 626 obtains data indicating the user's name or title and their contact information from the user information entry read in the processing of S230.

In step S234, the introduction device 626 reads, for example, from the user information, all entries whose user type indicates a broker. Furthermore, when the introduction device 626 obtains the user's address in the processing of S232, it selects the broker closest to the user's address.

Alternatively, the introduction device 626 reads the registration certificate from the real estate information that includes the real estate ID that is common to the distribution promotion information, and selects the brokerage agent that is closest to the location of the real estate indicated by the registration certificate.

In step S236, if the introduction device 626 obtains the user's name or title and address in the processing of S232, it causes the printer 102 to print a document introducing the intermediary agent, and also prints information indicating the destination of this document on an envelope.

Alternatively, when the user's email address or other information is obtained in the processing of S232, the introduction device 626 transmits electronic data for introducing the intermediary agent to the user to whom the intermediary agent is being introduced via the communication network 100 to the user terminal 30.

In step S238, the introduction device 626 determines whether the processes of S226 and S228 have been performed for all of the recipient IDs included in the distribution promotion information, that is, whether processing has been completed for all of the recipient IDs included in the distribution promotion information. If processing has been completed for all of the recipient IDs (Y in S238), the introduction device 626 proceeds to processing S240; if processing has not been completed for all of the recipient IDs (N in S238), the introduction device 626 returns to processing S226.

In step S240, the introduction device 626 deletes the distribution promotion information entry used in the intermediary introduction process and terminates processing.

The operation of the real estate service system 1 will be described below. First, the operation of the real estate information service server 4 to obtain a registration certificate from the Legal Affairs Bureau system 2 in response to a user operation or a request from the distribution promotion system 6, without receiving a request for the registration certificate from the user terminal 30, will be described. Figure 13 is a first communication sequence diagram illustrating the operation of the real estate service system 1.

Note that in the following explanations referring to communication sequence diagrams, it is assumed that information is input and output between the components of the user terminal 30 and real estate information service server 4 shown in Figures 1, 4 to 6, 9, and 10, and descriptions to that effect will be omitted. Similarly, descriptions of information being communicated between nodes of the real estate service system 1 via the communication network 100 will also be omitted.

As shown in FIG. 13, in step S300, the certificate application device 502 of the certificate acquisition system 52 of the real estate information service server 4 receives a user request operation on the UI device of the real estate information service server 4 and a request from the distribution promotion system 6.

In step S302, the certificate application device 502 of the certificate acquisition system 52 of the real estate information service server 4 applies to the Legal Affairs Bureau system 2 for issuance of a certificate of registered matters.

In step S304, the Legal Affairs Bureau system 2 issues a registration certificate to the certificate acquisition system 52, and the certificate receiving device 504 receives the registration certificate issued from the Legal Affairs Bureau system 2.

In step S306, the certificate receiving device 504 outputs the received registration certificate to the certificate DB 40 and stores it as certificate information.

In step S308, the fee payment device 506 receives a request for fee payment from the Legal Affairs Bureau system 2.

In step S310, the fee payment device 506 performs processing to pay the fee to the Legal Affairs Bureau system 2, in conjunction with the financial institution server 16. The fee payment device 506 also creates the payment information shown in Figure 8B and stores it in the accounting DB 48.

In step S312, the fee payment device 506 notifies the Legal Affairs Bureau system 2 of the payment of the fee.

In step S314, the financial institution server 16 performs a process to transfer the fee amount from the account of the operator of the real estate information service server 4 to the account of the Legal Affairs Bureau system 2.

Next, an example of the operation of the real estate service system 1 is shown, in which the real estate information service server 4 receives a request for a registration certificate from the user terminal 30, obtains the registration certificate from the Legal Affairs Bureau system 2, and provides it to the user terminal 30. Figure 14 is a second communication sequence diagram illustrating the operation of the real estate service system 1.

As shown in FIG. 14, in step S320, a process to create an account is carried out between the registration device 302 of the user terminal 30 and the user registration device 442 of the certificate provision service system 42 of the real estate information service server 4.

In other words, when a user operates the keyboard or other means of the UI device of the user terminal 30 to create an account on the real estate information service server 4, the registration device 302 transmits the information entered through this operation to the user registration device 442. The user registration device 442 receives the information from the registration device 302 and creates an account for the user. The user registration device 442 further creates the user information for the account shown in FIG. 7 and stores it in the user DB 46.

In step S322, a process for authenticating the user is carried out between the authentication device 304 and the user authentication device 444. That is, the authentication device 304 transmits information such as the user's ID and password to the user authentication device 444, which receives this information and authenticates the user. The user authentication device 444 outputs the results of this authentication to the user DB 46 and reflects them in the user information shown in Figure 7.

In step S324, the requesting device 306 requests the user request receiving device 448 to provide a registration certificate.

In step S326, the user request receiving device 448 receives the request from the requesting device 306 and outputs it to the certificate application device 502 of the certificate acquisition system 52. The certificate application device 502 applies for the issuance of a registration certificate to the Legal Affairs Bureau system 2.

In step S328, the Legal Affairs Bureau system 2 issues a registration certificate to the certificate receiving device 504. The certificate receiving device 504 receives the issued registration certificate and outputs it to the certificate providing device 450.

In step S330, the certificate providing device 450 transmits the issued registration certificate to the receiving device 310.

In steps S332 to S340, the same processing as steps S304 to S312 shown in Figure 13 is performed. That is, in step S332, the certificate receiving device 504 outputs the received registration certificate to the certificate DB 40 and stores it as certificate information.

In step S334, the fee payment device 506 receives a request for fee payment from the Legal Affairs Bureau system 2.

In step S336, the fee payment device 506 performs processing to pay the fee to the Legal Affairs Bureau system 2, in conjunction with the financial institution server 16. The fee payment device 506 also creates the payment information shown in Figure 8B and stores it in the accounting DB 48.

In step S338, the fee payment device 506 notifies the Legal Affairs Bureau system 2 of the payment of the fee.

In step S340, the financial institution server 16 performs a process to transfer the fee amount from the account of the operator of the real estate information service server 4 to the account of the Legal Affairs Bureau system 2.

In step S342, the user billing device 446 charges the payment device 308 a predetermined amount.

In step S344, when the user performs an operation to pay the amount charged, the payment device 308 performs a process to pay the amount charged to the financial institution server 16.

In step S346, the payment device 308 notifies the user billing device 446 that payment has been made according to the charge.

In step S348, the financial institution server 16 transfers the amount of the charge from the user's account to the account of the operator of the real estate information service server 4. The user billing device 446 also creates the billing information shown in Figure 8A and stores it in the user DB 46.

The following describes the operation of the distribution promotion system 6 in the real estate service system 1, where the distribution promotion system 6 reads certificate information from the certificate DB 40 and provides services for distribution promotion. Figure 15 is a third communication sequence diagram illustrating the operation of the real estate service system 1.

As shown in FIG. 15, in step S360, the distribution promotion information creation device 60 of the distribution promotion system 6 is activated in response to a user operation on the real estate information service server 4 or at regular intervals.

The real estate information creation device 600 further requests the certificate DB 40 to transmit certificate information indicating all or part of the registration certificate described with reference to Figures 3A to 3C.

In step S362, the certificate DB 40 transmits the certificate information in response to this request. The real estate information creation device 600 further analyzes the received certificate information, obtains data included in the registration certificate shown in Figures 3A to 3C and identifying the registration certificate, and outputs this data to the real estate information collection device 602.

In step S364, map information is requested from the map information server 14 using data input from the real estate information creation device 600 indicating the location of the real estate.

In step S366, the map information server 14 responds to this request by transmitting map information to the real estate information collection device 602. The real estate information collection device 602 receives the map information from the map information server 14 and outputs it to the real estate information creation device 600.

In step S368, advertising information is requested from the financial institution server 16 using data input from the real estate information creation device 600 indicating the location of the real estate.

In step S370, the financial institution server 16 transmits the advertising information to the real estate information collection device 602 in response to this request. The real estate information collection device 602 receives the advertising information from the financial institution server 16 and outputs it to the real estate information creation device 600.

The combination of S364 and S366 and the combination of S368 and S370 may be performed as needed, and both, either, or neither may be performed.

In step S372, the real estate information creation device 600 creates the real estate information shown in FIG. 11A and stores it in the real estate DB 606. The price estimation device 604 processes the real estate information stored in the real estate DB 606, estimates the transaction price of the real estate from the debt amount, interest, registration date, etc. included in the real estate information entry, and stores it in the real estate DB 606.

In step S374, the distribution promotion information creation device 608 is activated in response to a user operation on the real estate information service server 4 or at regular intervals, and requests the user DB 46 of the certificate provision service system 42 to send all or part of the user information entries shown in Figure 7.

In step S376, the user DB 46 transmits the user information to the distribution promotion information creation device 608 in response to this request.

In step S378, the distribution promotion information creation device 608 creates the distribution promotion information shown in FIG. 11B and stores it in the distribution promotion DB 610.

In step S380, the service providing device 62 of the distribution promotion system 6 is activated in response to a user operation on the real estate information service server 4 or at regular intervals. Furthermore, the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626 of the service providing device 62 read all or some of the entries of the distribution promotion information from the distribution promotion DB 610 and perform the processing described with reference to Figures 12A to 12D.

In step S382, the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626 create electronic data necessary to promote the circulation of real estate and transmit it to the user terminal 30 and terminal devices other than the user.

In step S384, the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626 cause the printer 102 to print documents and the like necessary to promote the circulation of real estate.

Note that in the processing of S380 to S384, it is not necessary for all of the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626 to be operating; it is sufficient for one or more of these to be operating. Furthermore, the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626 may selectively perform both or one of the processing of S382 and S384.

In the real estate service system 1 described above, the amount charged to the user by the real estate information service server 4 is set appropriately according to the management policy of the operator of the real estate information service server 4. For example, if the amount charged is set lower than the handling fee, the user can obtain the certificate of registered matters more cheaply than if they were to obtain it directly from the Legal Affairs Bureau system 2 without going through the real estate information service server 4.

On the other hand, the operator of the real estate information service server 4 will be able to obtain the registration certificates required for various services to promote the circulation of real estate at a reduced cost equal to the amount charged to the user. Therefore, by appropriately setting the amount of the charge in relation to the fee amount, benefits will be brought to both the user and the operator of the real estate information service server 4.

Furthermore, as shown in FIG. 11B, the distribution promotion information creation device 608 can assign a recipient ID to all real estate owners identified by the registration certificate indicated by the certificate information stored in the certificate DB 40, not just to users who have accounts on the real estate information service server 4. Therefore, the real estate service system 1 can provide services for promoting real estate distribution not only to that user, but also to all real estate owners that can be obtained by the certificate provision service system 42.

Below, we will explain modified examples of the operation of the real estate service system 1. Note that while the above example illustrates the creation of direct mail to promote real estate distribution, the real estate service system 1 can also provide a variety of other services, such as presenting real estate information exclusive to users.

Figures 16 and 17 are first and second communication sequence diagrams showing modified examples of the operation of the real estate service system 1. Figures 16 and 17 show a case in which the real estate information service server 4 shown in Figures 1, 5, and 6 in the real estate service system 1 changes its operation depending on whether or not certificate information indicating the registration certificate requested by the user shown in Figures 1 and 4 is stored in the certificate DB 40.

As shown in Figures 16 and 17, after steps S320 to S324 shown in Figure 14, the process proceeds to step S380. In step S380, the user request receiving device 448 queries the certificate DB 40 to determine whether certificate information indicating the requested registration certificate is stored.

As shown in FIG. 16, when the user request receiving device 448 receives a response from the certificate DB 40 indicating that the certificate information indicating the requested registration certificate is not stored, the processing of S336 to S348 shown in FIG. 14 is performed.

On the other hand, as shown in FIG. 17, certificate information indicating the requested registration certificate is stored in the certificate DB 40, and when the user request receiving device 448 reads this certificate information from the certificate DB 40 in step S384, processing of S330 is performed. Note that, as shown by the dotted line in FIG. 17, whether or not the real estate information service server 4 performs processing of S342 to S348 regarding billing the user depends on the operating policy of the operator of the real estate information service server 4.

In other words, for example, the operator of the real estate information service server 4 can operate in such a way that the operator does not charge a fee when providing a user with a registration certificate indicated by the certificate information stored in the certificate DB 40, but only charges a fee when providing a user with a registration certificate obtained from the Legal Affairs Bureau system 2.

Furthermore, the components that the service providing device 62 may include are not limited to the seller soliciting device 620, buyer soliciting device 622, information presentation device 624, and introduction device 626. For example, when the operator of the real estate information service server 4 provides a new service to promote the circulation of real estate, the circulation promotion information creation device 608 stores data indicating the service type of this new service in the circulation promotion information, and further adds components to realize this new service to the service providing device 62.

Figure 18 is a diagram showing a modified example of the distribution promotion information shown in Figure 11B. As shown in Figure 18, the distribution promotion information does not always need to include all of the data shown in Figure 11B; it may be sufficient to include data indicating the service type and one or more recipient IDs from among this data. The service providing unit 62 may use the distribution promotion information shown in Figure 18 to, for example, print using the printer 102 the name of the owner of the real estate indicated by the recipient ID included in each entry, and create an address sticker to be affixed to the direct mail envelope.

This novel embodiment can be embodied in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
