Description

[Technical field]

[0001] The present invention relates to a real estate ID acquisition device and a real estate ID acquisition method. [Background technology]

[0002] Companies and organizations, such as businesses and local governments, provide various services to consumers. When providing various services, it is sometimes necessary to know the address of the person to whom the service is provided. Companies and organizations can use such addresses to send documents with instructions on procedures, and can use the addresses to update the addresses of consumers registered in their customer database to the latest addresses. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-236007 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when such addresses are input by consumers via terminal devices, the way in which the address is written may differ depending on the consumer. For example, the address "1-1-1" may be input as "1-1-1," or a character with a similar appearance, such as a minus sign or a macron, may be input instead of a hyphen. In such cases, even though they indicate the same address, the character codes are different, making it difficult to distinguish whether the address known to the company or organization and the address input by the consumer are the same address. In such cases, the company or organization may not be able to identify how the consumer's address is written.

[0005] The present invention has been made in view of the above circumstances, and has an object to provide a real estate ID acquisition device and a real estate ID acquisition method that can grasp the notation of addresses in a unified manner. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, one aspect of the present invention is a real estate ID acquisition device having an element acquisition unit that acquires address elements corresponding to a first section based on an input operation by an operator from an address arranged in order from the largest section that makes up the address, a first extraction unit that extracts elements that may exist as an address in a second section that follows the acquired elements from a real estate database, a candidate display unit that displays the extracted elements as selectable candidates that can be input into the second section, and a second extraction unit that performs the process for each section that makes up the address in sequence in response to an element being selected from the displayed candidates, and when an address is identified, extracts a real estate ID corresponding to the identified address from the real estate database.

[0007] Another aspect of the present invention is a real estate ID acquisition method which acquires address elements corresponding to a first section based on an input operation by an operator from an address arranged in order from the largest section that makes up the address, extracts elements that may exist as an address in a second section following the acquired elements from a real estate database, displays the extracted elements as selectable candidates that can be input into the second section, and, as an element is selected from the displayed candidates, this is done in order for each section that makes up the address, and when an address is identified, extracts a real estate ID corresponding to the identified address from the real estate database. Effect of the Invention

[0008] As described above, according to the present invention, since a real estate ID can be identified, it becomes possible to refer to the address notation corresponding to the real estate ID, and it becomes possible to grasp the address notation in a unified manner.

[0010] A real estate ID management system according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram showing the configuration of a real estate ID management system S using a real estate ID acquisition device according to an embodiment of the present invention. The real estate ID management system S includes a plurality of terminal devices (10, 11), a real estate ID acquisition device 20, a real estate ID database 30, a business organization server 40, a postal code database 50, and a network N. A plurality of terminal devices (10, 11), a real estate ID acquisition device 20, a real estate ID database 30, a business organization server 40, and a postal code database 50 are connected via a network N so as to be able to communicate with each other.

[0011] The terminal devices 10 and 11 are used by, for example, individuals. The terminal device 10 may be, for example, a smartphone, a tablet, or a personal computer (PC). The terminal device 10 and the terminal device 11 have the same function for transmitting a real estate ID to the business organization server 40. The terminal device 10 and the terminal device 11 are used by different residents. Here, the case where there are two terminal devices, the terminal device 10 and the terminal device 11, will be described, but there may be three or more terminal devices, or there may be one terminal device. In this embodiment, the case where the terminal device 10 is operated by a resident who possesses the terminal device 10 will be described, but the terminal device 11 may also be operated by a resident who possesses the terminal device 11.

[0012] The real estate ID acquisition device 20 acquires a real estate ID in response to an operation input transmitted from the terminal device 10 or the terminal device 11, and transmits the acquired real estate ID to the business organization server 40.

[0013] In response to a request from the real estate ID acquisition device 20, the real estate ID database 30 transmits the real estate ID corresponding to the address to the real estate ID acquisition device 20.

[0014] The business / organization server 40 is used by a business or organization. A business may be any organization that uses real estate IDs, such as a bank, a credit card company, an insurance company, a shipping company, etc. An organization may be any organization that uses real estate IDs, such as a local government, a school, etc.

[0015] The postal code database 50 stores a postal code in association with a part of an address. This part of an address is an address from the top to the middle of a division that constitutes the address (for example, up to the Oaza).

[0016] The network N includes at least one of the Internet, a mobile phone network, a LAN (Local Area Network), etc. The network N may be at least one of a wired network and a wireless network.

[0017] FIG. 2 is a schematic functional block diagram showing the configuration of the real estate ID acquisition device 20. As shown in FIG. The real estate ID acquisition device 20 has a memory unit 201, a communication unit 202, an element acquisition unit 203, a first extraction unit 204, a candidate display unit 205, a second extraction unit 206, a real estate ID acquisition unit 207, a generation unit 208, an output unit 209, and a control unit 210. The storage unit 201 stores various types of data. The memory unit 201 is configured with a storage medium, for example, a hard disk drive (HDD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a random access read / write memory (RAM), a read only memory (ROM), or any combination of these storage media. The storage unit 201 may be, for example, a non-volatile memory.

[0018] The communication unit 202 communicates with various devices (the terminal device 10, the terminal device 11, the real estate ID database 30, the business organization server 40, and the postal code database 50) via the network N.

[0019] The element acquiring unit 203 acquires an element of the address that corresponds to the first division based on an input operation by an operator, from among the address that is arranged in descending order of the major divisions that make up the address. The categories are "Prefecture", "Branch Office", "County", "City, Ward, Town, Village", "Ward", "Town, Village", "City / Oaza", "Chome / Aza", "Banchi / No", "Building Name", "Room No", etc. Such categories may be determined according to the units used to separate addresses stored in the real estate ID database. An element is a character string that corresponds to a category, and represents a part of an actual address, such as "Tokyo", "Higashi-Shinbashi", or "Otemachi".

[0020] The first extraction unit 204 extracts elements that may exist as an address in the second division following the acquired element from the real estate ID database 30. For example, when the element of the first division is "Tokyo", elements that may exist as an address in the second division following the acquired element include elements of the next division such as "Minato Ward", "Shinagawa Ward", "Chofu City", and "Hachioji City", but do not include "Yokohama City", "Atami City", "Kyoto Prefecture", or "1-chome". In other words, an address that actually exists as an address following "Tokyo" may be included as an element, but an address that does not actually exist as an address following "Tokyo" is not included as an element. Also, if the element of the first division is "Kanagawa Prefecture," the elements of the next division include "Yokohama City," "Atami City," "Kawasaki City," etc., but do not include "Shinagawa Ward," "Funabashi City," "Shizuoka City," "Tokyo," etc. In other words, an address that actually exists as the address following "Kanagawa" can be included as an element, but an address that does not actually exist as the address following "Kanagawa Prefecture" is not included as an element. The first extraction unit 204 can extract from the real estate database any element that may exist as an address of the next division following the acquired element. For example, for elements of the next division following "Tokyo" and "Minato Ward", "Higashi-Shinbashi", "Toranomon", "Akasaka", etc. are extracted. In this way, the first extraction unit 204 can sequentially extract elements of the next division following the identified element until an address is identified.

[0021] The candidate display unit 205 displays the extracted elements as selectable candidates that can be input for the second segment. For example, the candidate display unit 205 displays the selectable candidates on the terminal device.

[0022] The second extraction unit 206 performs the extraction for each segment that makes up the address in sequence in response to an element being selected by the terminal device from the displayed candidates, and when the address is identified, extracts a real estate ID corresponding to the identified address from the real estate database.

[0023] The real estate ID acquisition unit 207 receives input of a real estate ID in response to an operation by an operator. The real estate ID can be input from any of the terminal devices (10, 11).

[0024] The generating unit 208 generates the reliability of the real estate ID depending on whether the real estate ID is acquired by the real estate ID acquiring unit 207 or acquired by extraction by the second extracting unit 206. The reliability indicates the degree of relationship between the real estate ID input to the terminal device 10 and the operator (e.g., a resident) who performed the input operation. For example, if the real estate ID corresponds to an address where the resident actually lives, the reliability is high. On the other hand, if the resident does not actually live in the place, has never lived in the place in the past, or shows someone else's address as if it is his / her own address, the reliability is low. The reliability can be said to be the degree to which it is possible to guarantee with a certain degree of certainty that the person who entered the real estate ID is the actual resident, based on the correspondence between the input real estate ID and the operator who performed the input operation.

[0025] The output unit 209 outputs the acquired real estate ID and reliability. The output unit 209 displays the real estate ID extracted by the second extraction unit 206 and the specified address together on the display screen of the terminal device.

[0026] The control unit 210 controls each unit of the real estate ID acquisition device 20 .

[0027] The above-mentioned communication unit 202, element acquisition unit 203, first extraction unit 204, candidate display unit 205, second extraction unit 206, real estate ID acquisition unit 207, generation unit 208, output unit 209, and control unit 210 may be composed of a processing unit such as a CPU (central processing unit) or a dedicated electronic circuit.

[0028] FIG. 3 is a diagram showing an example of real estate ID data stored in the real estate ID database 30. As shown in FIG. The real estate ID data is data in which a real estate ID (identifier) ​​is associated with an address. The real estate ID is a common code for uniquely identifying land or buildings. The real estate ID is identification information that can uniquely identify real estate even in cases where the address is prone to variations in notation or where there are multiple buildings at the same address and lot number. For such real estate IDs, addresses written in a uniquely determined address notation are associated and stored. Such addresses are stored here by category. In addition, the address referred to here may be either a residence or a residential address, as long as a real estate ID can be obtained.

[0029] Next, the operation of the real estate ID management system S will be described with reference to FIGS. FIG. 4 is a flowchart illustrating the operation of the real estate ID management system S. 5 and 6 are diagrams for explaining examples of screens displayed on the display screen of the terminal device 10. FIG. When transmitting a real estate ID from the terminal device 10 to the corporate organization server 40, the consumer performs an operation to determine whether or not to input a real estate ID. A real estate ID is transmitted from the terminal device 10 to the corporate organization server 40, for example, when a consumer using the terminal device 10 registers the consumer's address when applying for a credit card to a credit card company using the corporate organization server 40. When applying for such a real estate ID, the real estate ID is specified using a web form provided by the real estate ID acquisition device 20, and the specified real estate ID is transmitted to the corporate organization server 40, whereby the real estate ID is notified to the corporate organization server 40.

[0030] When the resident knows the real estate ID, he / she selects and inputs the option indicating that he / she knows the real estate ID (501 in FIG. 5) on the screen for selecting the input method (G1 in FIG. 5). Examples of cases where the resident knows the real estate ID include cases where the resident has a recording medium on which the real estate ID is stored, cases where the resident has a printed medium on which a machine-readable code representing the real estate ID is printed, cases where the resident knows the character string representing the real estate ID, etc. The storage medium may be any medium on which the real estate ID is stored, such as a personal card, a machine-readable code, etc. The personal card may be, for example, a My Number card, a driver's license, a health insurance card, etc., as long as it is equipped with an IC (integrated circuit) chip on which the real estate ID is stored. The machine-readable code may be any code that can be optically read by a reader, and may be, for example, a barcode, a two-dimensional barcode, etc. Such a machine-readable code may be printed on a paper medium, for example.

[0031] If a resident does not know the real estate ID, the resident can specify the real estate ID by inputting the address. In this case, the resident selects and inputs the option (502 in FIG. 5) indicating that the real estate ID is not known on the screen (G1 in FIG. 5) for selecting the input method. The terminal device 10 transmits the contents of the operation input to the real estate ID acquisition device 20 .

[0032] (Step S101) The control unit 210 of the real estate ID acquisition device 20 determines, based on the operation content transmitted from the terminal device 10, whether or not a real estate ID is input.

[0033] When input of a real estate ID is selected (step S101-YES), the control unit 210 of the real estate ID acquisition device 20 transmits, to the terminal device 10, an instruction to read the real estate ID. When the terminal device 10 receives an instruction to read the real estate ID from the real estate ID acquisition device 20, the terminal device 10 displays a message "Please read the real estate ID" on the display screen of the terminal device 10. When the resident checks this display, the real estate ID is read by the terminal device 10. Here, the resident may input a character string representing the real estate ID from an input device such as a touch panel or a keyboard.

[0034] When a resident wants to have a real estate ID read, they can either bring the recording medium on which the real estate ID is stored close to the terminal device 10 to have it read, or they can have the real estate ID read by having the camera of the terminal device 10 take an image of a medium on which a machine-readable code is printed. When a personal card on which a real estate ID is stored is brought close to the terminal device 10, the terminal device 10 reads the real estate ID from the IC chip of the personal card by using a contactless communication function. When reading a machine-readable code, when a print medium on which the machine-readable code is printed is brought close to the terminal device 10, the terminal device 10 captures an image of the machine-readable code using a camera mounted on the terminal device 10, and interprets the machine-readable code contained in the captured image to obtain the real estate ID.

[0035] (Step S102) The terminal device 10 displays the acquired real estate ID on the display screen (G2 in FIG. 5) (511 in FIG. 5). Then, when the resident presses the “Search” button (512 in FIG. 5), the terminal device 10 transmits the real estate ID to the real estate ID acquisition device 20.

[0036] (Step S103) The real estate ID acquisition unit 207 of the real estate ID acquisition device 20 acquires, from the real estate ID database 30, an address corresponding to the real estate ID received from the terminal device 10.

[0037] (Step S104) The output unit 209 of the real estate ID acquisition device 20 transmits the acquired address together with the real estate ID to the terminal device 10, thereby causing the terminal device 10 to display the address and real estate ID (reference symbol G3 in FIG. 5). Here, the terminal device 10 displays the real estate ID and the address notation on the screen in an uneditable state. This makes it possible to prevent the resident from modifying or deleting the address acquired according to the real estate ID, and allows the address notation to be confirmed in this unedited state. In addition, when a real estate ID is manually input by a resident, the address obtained according to the real estate ID may be displayed in an editable manner. In this case, the input real estate ID may be erroneously input or the real estate ID of an address with little relevance to the resident may be input, so the address may be editable. In contrast, when a recording medium storing a real estate ID is read, there is no erroneous input in the character string of the real estate ID itself, and since a personal card or the like possessed by the resident can be used, the input real estate ID is considered to be correct with a certain degree of certainty, so it is possible to prevent the resident from editing the address corresponding to the real estate ID.

[0038] When the terminal device 10 receives the address and the real estate ID from the real estate ID acquisition device 20, the terminal device 10 displays the received address and real estate ID on the display screen. Here, the terminal device 10 also displays the "Back" (reference number 521 in FIG. 5) and "Next" (reference number 522 in FIG. 5) buttons on the display screen. The resident checks the real estate ID and the address displayed on the display screen and judges whether or not the real estate ID and the address may be sent to the corporate organization server 40. For example, if the resident can visually check the real estate ID itself and judge whether it is the intended real estate ID, the resident judges whether or not the real estate ID may be sent by visually checking the real estate ID. If it is difficult for the resident to judge whether the real estate ID is the intended real estate ID by the real estate ID itself, the resident judges whether or not the address may be sent by visually checking the address. Here, since the address and the real estate ID correspond to each other, if the address is the intended one, it can be judged that the real estate ID is also the intended one. In addition, when a character string representing a real estate ID is manually input via an input device, if a part of the input character string is input incorrectly, the address for the input real estate ID cannot be obtained, or an address different from the expected address is displayed, so that it is possible to know that the input real estate ID is incorrect. If the real estate ID or address is the intended one, the resident presses “Next” (reference number 522 in FIG. 5 ), and if not, presses “Back” (reference number 521 in FIG. 5 ). The terminal device 10 transmits operation data representing the button pressed by the resident to the real estate ID acquisition device 20.

[0039] (Step S105) When the control unit 210 of the real estate ID acquisition device 20 receives the operation data from the terminal device 10, it determines whether the received operation data is "next" or "back." If the button is the "Back" button (step S105-"Back"), the control unit 210 transmits to the terminal device 10 an instruction to transition to a selection screen for inputting or not inputting a real estate ID, to the terminal device 10. As a result, the process transitions to step S101.

[0040] (Step S106) If the button is the "Next" button (step S105--"Next"), the generation unit 208 assigns a reliability to the real estate ID identified in response to the operation input from the terminal device 10. Here, the generating unit 208 may assign a reliability according to the process (identification method) until the input real estate ID is identified. For example, in step S101, the generation unit 208 may assign a higher reliability to a case where the real estate ID is identified by inputting from the terminal device 10 than to a case where the real estate ID is identified by inputting an address. Here, when inputting an address to identify a real estate ID, there is a possibility that an address that exists but is unrelated to the operator of the terminal device 10 (for example, an address published on an Internet homepage or in a telephone directory, etc.) may be input, so the reliability may be set lower than when inputting a real estate ID. Note that when the reliability is relatively low, in addition to inputting the real estate ID or address, a copy of an official identification document may be registered, and a process of identity verification such as official personal authentication may be performed.

[0041] In addition, when obtaining a real estate ID, if an address is manually input by a resident, the programming (processing) for receiving the real estate ID corresponding to that address is different, so if the route used to obtain the address notation used to identify the real estate ID is a specified route, the generation unit 208 may determine that the real estate ID has been identified by inputting the address and set the reliability.

[0042] Furthermore, the generating unit 208 may generate different reliability levels depending on the method for inputting the real estate ID. For example, when the real estate ID is specified in response to reading a recording medium in which the real estate ID is stored, the reliability may be set higher than that of other identification methods. This is because, in general, the resident has a My Number card, a driver's license, a health insurance card, etc., as a recording medium in which the real estate ID is stored. Here, even if the recording medium in which the real estate ID is stored is read, an operator other than the resident may perform a reading operation using a third party's recording medium. In such a case, when reading the recording medium, the resident may be asked to input information for identity verification, such as a password or a PIN code, and the real estate ID may be read from the recording medium if it is determined that the password or PIN code is correct as a result of the comparison. Then, when the real estate ID is obtained by such comparison, the generating unit 208 may assign a higher reliability to the case in which the real estate ID is read from the recording medium after comparison than to the case in which the recording medium in which the real estate ID is stored is read without comparison.

[0043] In addition, the generation unit 208 may be configured to generate a lower reliability when the real estate ID is identified by reading a machine-readable code indicating the real estate ID compared to when the real estate ID is identified by reading a recording medium. The machine-readable code can be obtained by the resident himself / herself, but it may also be obtained by a third party. In this case, a third party other than the resident himself / herself may obtain the machine-readable code and have it read. In this case, for example, the machine-readable code may include not only the correct real estate ID but also a confirmation code including at least one of a hash value, an issuer code, and the like. In this way, when a third party simply generates a machine-readable code corresponding to the real estate ID and has the terminal device 10 read it, the real estate ID can be obtained from the machine-readable code, but a confirmation code such as a hash value or an issuer code cannot be generated or included in the machine-readable code in advance, so it is possible to identify whether the machine-readable code has been issued by a legitimate issuer. Therefore, even when a real estate ID is obtained from a machine-readable code, the code may be generated so that the code is more reliable when the confirmation code is included than when the confirmation code such as a hash value or an issuer code is not included.

[0044] The generating unit 208 may use data indicating which of a plurality of levels of reliability it is, or may use a flag as data indicating the reliability. When using a flag, it may set "1" when the real estate ID is read by the terminal device, and may set "0" when the real estate ID is specified based on the input of the address. In this case, it is possible to grasp that at least the reliability is higher when the real estate ID is read by the terminal device than when the real estate ID is specified based on the input of the address.

[0045] In this way, by using the reliability, it is possible to identify whether the resident himself knows the real estate ID and has entered the known real estate ID, or whether the real estate ID has been specified in response to the input of the address. In addition, when the reliability is set to include whether the resident himself has read the recording medium on which the real estate ID is stored, information as to whether the person operating the device is the resident himself can also be used as information for determining reliability.

[0046] In addition, if the real estate ID is published on a website or the like on the Internet, or if real estate introduction documents or the like containing the real estate ID are circulated, there is a possibility that anyone may be able to access the real estate ID. Even in such a case, as described above, the reliability of whether or not the real estate ID is entered by the consumer himself / herself can be grasped by having the consumer enter identity verification information such as a password or PIN code and verifying the information, or by using a verification code.

[0047] (Step S107) When the reliability is assigned, the control unit 210 transmits the real estate ID together with the reliability to the business organization server 40.

[0048] (Step S111) If the input of the real estate ID is not requested in step S101, the control unit 210 of the real estate ID acquisition device 20 causes the terminal device 10 to display an input screen for inputting a postal code. The terminal device 10 displays an input screen (G4 in FIG. 6 ) for inputting a postal code based on an instruction from the real estate ID acquisition device 20. On this input screen, the resident inputs a postal code corresponding to his / her address in a postal code input field (531 in FIG. 6 ). The terminal device 10 transmits the postal code input by the resident to the real estate ID acquisition device 20.

[0049] (Step S112) The control unit 210 of the real estate ID acquisition device 20 acquires the postal code transmitted from the terminal device 10, and reads out the address corresponding to the acquired postal code from the postal code database 50. The address acquired here is not data including all of the divisions that make up the address, but the address from the top division to the middle divisions. For example, when the postal code "105-XXXX" is input, a character string indicating the address up to "Higashi XX 1-chome, Minato-ku, Tokyo" is acquired. Here, a unified address notation corresponding to the postal code can be obtained, and variations in notation that may occur depending on the resident can be eliminated.

[0050] (Step S113) The control unit 210 of the real estate ID acquisition device 20 transmits the acquired address to the terminal device 10 and displays it on the display screen. As a result, the address corresponding to the postal code is displayed on the display screen (screen G5 in FIG. 6) of the terminal device 10 (reference numeral 541 in FIG. 6). In this case, since the address can be identified up to "Higashi XX 1-chome, Minato-ku, Tokyo" based on the postal code, the address up to the identified portion is displayed on the screen.

[0051] (Step S114) Next, the first extraction unit 204 of the real estate ID acquisition device 20 refers to the real estate ID database 30 based on the last division (1-chome) of the acquired address, and acquires elements of the address division belonging to the element "1-chome" of this last division "chome". That is, in this case, since the address can be specified up to "Tokyo Minato-ku Higashi XX 1-chome" based on the postal code, the division corresponding to "1-chome" is set as the first division, and elements that may exist as an address of the second division "banchi" following the element "1-chome" of this first division are acquired. For example, if "Tokyo Minato-ku Higashi XX 1-chome" has numbers 1 to 10, the first extraction unit 204 acquires elements "1-banchi" to "10-banchi" for the division "banchi" as candidates. Although the case where an address up to "1-chome Higashi XX, Minato-ku, Tokyo" is obtained by searching using a postal code will be described here, it is also possible to have the consumer select from elements corresponding to the "prefecture" category, such as "Tokyo." In this way, even if it is not possible to extract an address corresponding to a postal code, it is possible to accept input in order from the major categories that make up the address and specify the address.

[0052] (Step S115) The candidate display unit 205 of the real estate ID acquisition device 20 transmits each of the candidates ("No. 1" to "No. 10") obtained by the first extraction unit 204 to the terminal device 10 as options, and causes the terminal device 10 to display them. Here, for example, the terminal device 10 displays the candidates received from the real estate ID acquisition device 20 as options in a pull-down menu.

[0053] (Step S116) When the terminal device 10 accepts a selection from among the options based on an operational input from the resident, it transmits the selected option to the real estate ID acquisition device 20. For example, when "No. 7" is selected from the options "No. 1" to "No. 10," data indicating "No. 7" is transmitted from the terminal device 10 to the real estate ID acquisition device 20. In addition, the terminal device 10 displays the selected and confirmed option on the display screen (reference number 542 in FIG. 6). The control unit 210 of the real estate ID acquisition device 20 acquires the option ("No. 7") transmitted from the terminal device 10 by receiving it.

[0054] (Step S117) The first extraction unit 204 receives the option transmitted from the terminal device 10, concatenates the received option to the end of the address extracted up to now, and determines whether the address has been identified. Here, the first extraction unit 204 may inquire of the real estate ID database 30 whether there is a section element following the end of the address extracted up to now (here, "7th"), and if there is no next section element, determine that the address has been identified, and if there is a next section element, determine that the address has not been identified.

[0055] If the address cannot be specified (step S117-NO), that is, if there is an element of the section following the end of the address extracted so far, the first extraction unit 204 of the real estate ID acquisition device 20 determines that the address has not been specified and returns to step S114. As a result, candidates for the element of the next section following the element currently acquired from the terminal device 10 are acquired from the real estate ID database. This process is repeated until the address is specified (until the last section constituting the address is reached). For example, if "1" to "3" can exist as addresses as candidates for the section "number" following "7", "1" to "3" are acquired as candidates. Then, when "3" is selected (FIG. 6, reference numeral 543), the section "number" is set as the first section, the section "building name" following the element "3" is set as the second section, and "Shiodome Mansion" and "XX Mansion" are acquired as candidates as the elements. In this case, the process is repeated until the room number is specified. As a result, the category "Building Name" is acquired as the element "Shiodome Mansion" and the category "Room Number" is acquired as the element "101." In this way, the address can be identified by having the user select elements of address categories that were not identified by the postal code, starting from the largest category (reference number 544 in Figure 6).

[0056] (Step S118) If the second extraction unit 206 of the real estate ID acquisition device 20 can identify the address (step S117-YES), that is, if there is no element of the next division following the end of the address extracted so far (if the end element of the address can be acquired), it acquires the real estate ID corresponding to the identified address from the real estate ID database 30.

[0057] (Step S119) The output unit 209 of the real estate ID acquisition device 20 transmits the real estate ID and the specified address to the terminal device 10, and causes the terminal device 10 to display the real estate ID together with the address (reference numeral 545 in FIG. 6), and then causes the process to proceed to step S105. Then, when "Next" (reference number 547 in FIG. 6) is selected in step S105, the generation unit 208 generates a reliability according to the fact that the real estate ID is obtained by inputting the address. When the reliability is assigned, the control unit 210 transmits the real estate ID together with the reliability to the business organization server 40. Note that, when "Back" (reference number 546 in FIG. 6) is selected in step S105, the control unit 210 transitions the process to step S101.

[0058] In the above-described embodiment, when the real estate ID is transmitted to the business organization server 40, the reliability is transmitted together with the real estate ID. This enables the business or organization using the business organization server 40 to carry out operations according to the reliability. For example, if the reliability is shown to be above a certain level, the data can be used in subsequent processes to update the real estate ID in the customer master or to update addresses based on the real estate ID, without the administrator having to perform visual inspections or other confirmation tasks, or after checking fewer items than usual in the confirmation tasks. This reduces the workload.

[0059] In addition, when performing a task of sending documents to consumers, if the reliability is below a certain level, the documents may be sent as personal delivery mail, and if the reliability is above a certain level, the documents may be sent as regular mail, thereby reducing postal costs. If the reliability is below a certain level, the system may contact the resident himself / herself by phone as necessary to confirm the address, etc., but if the reliability is above a certain level, the system may omit contacting the resident himself / herself by phone to confirm the address, thereby improving the accuracy of the address and reducing the workload. In this way, a company or organization that has obtained a real estate ID and trustworthiness can take action in accordance with the company or organization's policies, depending on the information indicating the degree of trustworthiness.

[0060] In the above-mentioned embodiment, it has been described that a My Number card can be used as a personal card. Here, when a My Number card is used as a personal card, the four basic pieces of information can be obtained from the My Number card, and the four basic pieces of information include an address. Therefore, since the address can be obtained from the My Number card, even if a real estate ID is not recorded on the My Number card, the real estate ID database 30 may be searched using the address included in the four basic pieces of information to obtain a real estate ID.

[0061] Furthermore, if a real estate ID is stored in a personal card, even if the address notation included in the four basic pieces of information obtained from the My Number card does not match the address notation stored in the real estate ID database 30, the address corresponding to the real estate ID can be obtained by acquiring the real estate ID from the personal card. This makes it possible to unify the address notation to the notation determined by the real estate ID.

[0062] Furthermore, even if a real estate ID is stored in a personal card and the address notation included in the basic four information obtained from the My Number card matches the address notation stored in the real estate ID database 30, the address can be identified by using the real estate ID without using the basic four information. This makes it possible to identify an address without using the basic four information, and therefore this can be provided as a new input method for entering an address. This increases the options for selecting an input method that is easy for consumers to use.

[0063] In the above-described embodiment, possible elements of an address are displayed as candidates for each section that constitutes an address, and the resident is asked to select one. This allows the resident to select options one by one until the address is identified, thereby obtaining the notation up to the end of the address. In this case, it is not necessary for the resident to input the description of the address by text input or the like. Therefore, if there is variation in the way that residents input characters that look similar but have different character codes, such as "-" (hyphen), "-" (minus sign), and "ー" (macro note), it may be difficult to identify the address. However, this variation in input method can be eliminated, making it easier to identify the real estate ID. This allows users to input an address according to an address expressed according to a set rule (here, the notation of the address stored in association with the real estate ID). The address entered in this way is written according to the notation of the address stored in association with the real estate ID, and by making the reference to a unified address, it can be treated as a common address even for multiple companies. Therefore, when an address is entered by a consumer as text, there will be variation in notation, but by making the reference to a unified address, it is possible to obtain an address without variation in notation.

[0064] In the above embodiment, the input of the real estate ID is accepted when the real estate ID is known, and when the real estate ID is not known, the real estate ID is identified by having the address input, and the real estate ID is provided to the company or organization. However, a function for identifying the real estate ID by inputting an address may be provided independently. This may be provided as an application program that can look up the real estate ID based on the address. For example, when sending mail or deliveries, the real estate ID may be looked up from the address, and the delivery destination may be specified by setting (entering) the real estate ID.

[0065] In the above embodiment, the case has been described where the function for identifying the real estate ID is installed in the real estate ID acquisition device 20, but at least a part of the functions of the real estate ID acquisition device 20 may be installed in the terminal device 10. For example, at least one of the storage unit 201, the communication unit 202, the element acquisition unit 203, the first extraction unit 204, the candidate display unit 205, the second extraction unit 206, the real estate ID acquisition unit 207, the generation unit 208, the output unit 209, and the control unit 210 may be installed in the terminal device 10. In addition, the functions of the real estate ID acquisition device 20 may be installed in the business organization server 40.

[0066] In the above-described embodiment, the real estate ID database 30 may store addresses divided into sections, or may store addresses in a continuous manner without being divided into sections. If addresses are stored in a continuous manner in the real estate ID database 30, the real estate ID acquisition device 20 may divide the continuous address obtained from the real estate ID database 30 into sections before using it.

[0067] In the above-described embodiment, the real estate ID may be a real estate ID that can be commonly used even if different companies or organizations are involved. In this case, when a company notifies another company of a real estate ID acquired using the real estate ID acquisition device 20, the address (or real estate) can be identified without checking whether there are variations in the address spelling. Furthermore, by commonly using the data stored in the real estate ID database 40 among different companies or organizations, it becomes possible for the different companies or organizations to use the address spelling corresponding to the real estate ID. This makes it possible for addresses to be shared among different companies or organizations without variations in the address spelling.

[0068] The storage unit 201, the communication unit 202, the element acquisition unit 203, the first extraction unit 204, the candidate display unit 205, the second extraction unit 206, the real estate ID acquisition unit 207, the generation unit 208, the output unit 209, and the control unit 210 in the above-mentioned embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read into a computer system and executed to realize the function. Note that the "computer system" here includes hardware such as an OS and peripheral devices. Furthermore, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, an optical magnetic disk, a ROM, a CD-ROM, and a storage device such as a hard disk built into a computer system. Furthermore, the "computer-readable recording medium" may also include a device that dynamically holds a program for a short period of time, such as a communication line when a program is transmitted via a network such as the Internet or a communication line such as a telephone line, and a device that holds a program for a certain period of time, such as a volatile memory inside a computer system that is a server or client in that case. Furthermore, the above program may be for realizing part of the functions described above, or may be capable of realizing the functions described above in combination with a program already recorded in a computer system, or may be realized using a programmable logic device such as an FPGA (Field Programmable Gate Array).

[0069] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and designs that do not deviate from the gist of the present invention are also included. [Explanation of symbols]
