Description

  The present invention relates to a duplication potential person detection device, a duplicate registrant detection method, and a program thereof for detecting registrant information that may be duplicated in a database.

Conventionally, for the purpose of improving the efficiency of local administration in each local government, there is a technology that realizes the online conversion of registrant information such as resident records, etc., and the application and notification of individuals and companies to the local government (Patent Literature) 1).
JP 2003-006379 A (paragraphs [0012] to [0039])

  However, in the above-described technology, a method for accurately and efficiently integrating registrant information such as resident records of municipalities when local governments (municipalities) merge is not considered.

  In other words, the registrant information for each municipality includes not only information on those who currently have an address in that municipality, but also those who do not have an address in that municipality (transferrs and residents of other municipalities, only fixed assets). For example, when registrant information of A city and B registrant information are integrated, registration of residents of B town who have fixed assets in A city There is a possibility that two pieces of information are created (duplicately registered) for the A city and the B town for the same person.

If such duplicate registration is left as it is, grasping of resident tax storage and determination of the tax exemption point of property tax may not be performed correctly, and there is a risk of inducing taxation on the resident.
Therefore, in the integration of registrant information for each municipality, specify which registrant information and which registrant information is registrant information of the same person, and summarize the registrant information of the same person (so-called name identification). It is important to do and organize registrant information.

However, in the prior art, the registrant information of the same person is specified only by the name and date of birth of the registrant of the municipality. For example, an external character (JIS (Japan Industrial Standard) is displayed in the name field of the registrant information of the municipality. ) When characters outside the code system) were used, or when there was an input error, name identification was not performed correctly.
Considering the recent increase in the merger of municipalities against the background of the declining birthrate and aging of the population, and the progress of digitization of registrant information such as resident records, the above problems may increase. .

  Therefore, in the present invention, a duplication possibility person detection device and duplication possibility person detection method for solving the above-described problem and accurately and efficiently performing the same person identification (duplication possibility person detection) in a plurality of registrant information, etc. It is an issue to provide.

In order to solve the above-mentioned problem, in the present invention, the identification information matching unit of the duplication potential person detecting device uses the identification information of the registrant (in the embodiment described later, name, date of birth, personal number of the municipality, etc.) Matching (identification) is performed, and registrant information having the same identification information is specified.
At the same time, the imprint information matching unit of the duplication potential person detecting device performs matching based on the seal imprint information (image data of the seal stamp) registered in each municipality, and specifies the seal stamp information having the same seal stamp information.
Then, based on the seal stamp information having the same seal imprint information and the registrant information having the same identification information, from the acquired registrant information, the registrant information whose duplication possibility person detection unit may be duplicated It was set as the structure which detects.
According to this configuration, detection of registrant information that may be duplicated is performed by a combination of the name and date of birth included in each registrant information and the seal imprint information of the seal, so the detected registrant information is It will be more likely to overlap.
In the embodiment described later, the identification information matching unit also functions as a duplication possibility person detecting unit.

  According to the present invention, for example, when registrant information of each municipality is integrated, it is possible to detect registrant information that is likely to be the same person in advance. Further, it is possible to reduce time and labor when determining whether the registrant information is the same person information manually or visually. That is, the administrator can perform name identification more efficiently and accurately. Further, it is possible to prevent a plurality of registrant information of the same person from being registered (duplicate registration) in the unified registrant information database.

  The configuration of a duplication potential person detection device and the duplication possibility person detection method which are the best mode for carrying out the present invention will be described with reference to FIGS.

FIG. 1 is a block diagram showing a configuration of a duplication potential person detection system including a duplication possibility person detection device according to an embodiment of the present invention.

  As shown in FIGS. 1 and 3, the duplication possibility person detection system according to the embodiment of the present invention is a registrant information storage unit that stores registrant information (information other than resident records and resident records) of each municipality. 201A to 201C, seal stamp information storage units 202A to 202C for storing seal stamp information registered in each municipality, and registrant information and seal stamp information are acquired via the network 3, and the registrant included in this registrant information Referring to identification information (name / birth date) and seal information, it includes a duplication potential person detection device 100 that detects registrant information that is likely to be the same person. The network 3 may be an IP network represented by the Internet, or a LAN (Local Area Network), and may be wireless or wired.

First, the registrant information storage units 201A to 201C will be described. Here, the registrant information storage unit 201A in A city will be described as an example with reference to FIG.
As shown in FIG. 3A, the registrant information storage unit 201A stores resident records of A city as registrant information of A city and information (information other than resident records) of persons who are not residents of A city. Store. Here, the information other than the resident record is, for example, information on a person who owns fixed assets such as land and buildings in A city, information (history) about a person who has lived in A city in the past, and the like.

As illustrated in FIG. 3B, the resident record includes information such as personal number, name, date of birth, etc. in each municipality. In addition, information on an address and a telephone number may be included.
The information other than the resident record includes items such as the personal number, name, date of birth, and the like of the municipality as illustrated in FIG. For example, when this information is information on fixed assets, it may include information on the location (location) of the asset, and when this information is information (history) on a person who has already moved out of A city, You may comprise including the flag which shows that it is the information (history) regarding the address when living in A city, and the person who has already moved out of A city.
As illustrated in FIG. 3D, the seal stamp information includes a personal number (identification information of the registrant), seal number (identification information of the seal information), and seal impression information (image data) of each municipality. The In addition, the seal information may include information on the name and address of the seal registrant and seal information (history) of the person transferred from A city.

  The duplication possibility person detecting device 100 acquires information other than resident records and resident records as registrant information from the registrant information storage units 201A to 201C via the network 3, and seal information from the seal information storage units 202A to 202C. To get. And it has the function to detect the registrant information with high possibility of being the same person with reference to the registrant identification information (name and date of birth) included in the registrant information and the seal imprint information included in the seal stamp information.

The duplication possibility person detecting device 100 acquires registrant information (information other than the resident record and the resident record) of each municipality from the registrant information storage units 201A to 201C via the network 3, and the seal stamp information storage units 202A to 202A Data acquisition unit 110 that acquires seal information from 202C, a registrant who may overlap based on registrant identification information and seal imprint information of the acquired registrant information (possibly registrant information of the same person) A processing unit 120 that detects (sorts) information, a storage unit 130 that stores registrant information detected (separated) by the processing unit 120, an output unit 140 that outputs information stored in the storage unit 130, and a processing unit 120 It includes an input unit 150 for inputting various information.
Here, the output unit 140 includes a monitor or the like, and the input unit 150 includes a keyboard or a mouse.

The processing unit 120 includes a CPU, a memory, and the like, and may be duplicated based on the registrant identification information and seal imprint information of the registrant information acquired from the data acquisition unit 110 (can be registrant information of the same person). It has a function to detect (separate) registrant information.
Therefore, the processing unit 120 includes the seal stamp information matching unit 121 that specifies seal information having the same (or similar / similar) seal stamp information from the seal stamp information acquired via the data acquisition unit 110, and the data acquisition unit 110. An identification information matching unit 122 that identifies registrant information having the same registrant identification information (name, date of birth, and personal number) among the registrant information acquired via the ID and detects a potential duplicate person. Composed.
Details of processing procedures of the seal imprint information matching unit 121 and the identification information matching unit 122 will be described in the section of processing procedure of the duplication possibility person detecting device 100 described later.

  The storage unit 130 includes a registrant information stored in the duplication registrant information stored in the data acquisition unit 110, and a registrant information acquired in the data acquisition unit 110. And a registrant information storage unit 132 that stores registrant information excluding registrant information that may be duplicated.

  In the duplicate registration possibility person information storage unit 131, 1) registrant information with the same name / birth date / imprint information, 2) registrant information with the same name / birth date, 3) only imprint information Three types of information of registrant information with the same are stored.

The registrant information stored in the duplicate registration possibility person information storage unit 131 is as follows: 1) For registrant information with the same name, date of birth, and seal information, the personal number, seal number, name, and year of birth of each municipality It consists of items (information) such as date and time. 2) For registrant information with the same name and date of birth, it consists of items (information) such as individual number, name, and date of birth of each municipality. 3) Registrant information in which only the seal stamp information is the same includes items (information) such as personal numbers and seal numbers.
In addition, 2) Registrant information with the same name and date of birth is the same as the name and date of birth, but the imprint information is different from the registrant information, and there is no corresponding seal information itself (Registrant information) is also included.
The details of the duplication possibility person information stored in the duplication registration possibility person information storage unit 131 will be described in the section of the processing procedure of the duplication possibility person detection device 100 described later.

  As described above, the registrant information storage unit 132 has a function of storing information obtained by removing registrant information that may be duplicated from the registrant information acquired by the data acquisition unit 110.

Next, the processing procedure of the duplication possibility person detection of the duplication possibility person detection apparatus 100 is demonstrated using the flowchart of FIG.
Here, the case where registrant information of A city, B town, and C village is integrated will be described as an example with reference to FIGS. 1 and 3 as appropriate.

(Step S101)
In step S101, the data acquisition unit 110 of the duplication possibility person detecting device 100 performs registration information (resident record and resident record) of A city, B town, and C village from the registrant information storage units 201A to 201C via the network 3. Information) is acquired, stamp information of A city, B town, and C village is acquired from the seal information storage units 202A to 202C, and these information is output to the processing unit 120.

  Here, the data acquisition unit 110 converts the acquired registrant information into a format that can be processed by the processing unit 120. In this way, even when the format (layout) of the acquired registrant information is different, the processing unit 120 can easily perform matching (identification processing).

(Step S102)
In step S102, the processing unit 120 acquires registrant information (information other than resident records and resident records) and seal information of A city, B town, and C village acquired in step S101. And a duplication possibility person is detected for every registrant information of each municipality, and registrant information is collated for every municipality.
Here, name identification means that when there is a plurality of registrant information for the same person, this information is collected for each person.

For example, as shown in FIG. 3, the identification information matching unit 122 of the processing unit 120 detects a duplication possibility person in the resident record of the registrant information of A city and information other than the resident record, performs name identification, The registrant information (see FIG. 3E) is created by integrating the resident record and information other than the resident record.
Specifically, matching is performed by the personal number or name / birth date of each resident record in City A and information other than the resident record, and the information on the registrant information of the same person is specified, and the same person is registered. The registrant information is compiled (name identification) and registrant information is created by integrating the resident record and information other than the resident record.
Similarly, for the registrant information of B town and C village, registrant information is created by integrating the resident record and information other than the resident record.

  The identification information matching unit 122 has a character code conversion function and an external character identification function. By doing in this way, the identification information matching part 122 is effective also about these character information, even when character information in which character codes differ, an external character, etc. are contained in information other than a resident record and a resident record. The registrant information can be identified as the same character.

(Step S103)
In step S103, the identification information matching unit 122 searches the registrant information of A city, B town, and C village created in step S102 for information having the same name and date of birth. That is, the identification information matching unit 122 identifies information that may be duplicated (highly likely to be the same person) from the registrant information. Then, information on the possibility of duplication (name and date of birth) is created.
Table 1 below is a table exemplifying information on the possibility of duplication (name and date of birth).

As exemplified in Table 1, the information on the possibility of duplication (name / birth date) includes information such as the personal number, name, date of birth, etc. of each municipality.
For example, in the case of the example in Table 1, as registrant information common to the name “IIII” and the date of birth “JJJJ”, the registrant information whose personal number in City A is “GGGG” and the personal number in Town B is “ This indicates that there is registrant information “HHHH”.

(Step S104)
In step S104, the imprint information matching unit 121 of the processing unit 120 has the same imprint information from the stamp information acquired in step 101 (here, the seal information of A city, B town, and C village) (or similar / Search for seal stamp information (approximate). In other words, the imprint information matching unit 121 identifies information that may be duplicated (highly likely to be stamp information of the same person) from the acquired seal stamp information, and creates information on the possibility of duplication (imprint). Then, this information is stored in the duplication registration possibility person information storage unit 131 of the storage unit 130.
Table 2 below is a table exemplifying information on the possibility of duplication (imprint) created by the imprint information matching unit 121.

As illustrated in Table 2, the information on the possibility of duplication (imprint) is composed of information such as the personal number and seal number of each municipality.
For example, in the case of the example in Table 2, as the seal stamp information having the same seal information, the stamp information with the city A personal number “GGGG” and the city A stamp number “KKKK”, and the city B personal number “HHHH” indicates that there is seal information in which the stamp number of town B is “LLLL”.

  Then, the registrant identification information (personal number or name / birth date of the municipality) included in the specified seal information is output to the identification information matching unit 122.

  The imprint information matching unit 121 obtains the stamp information so that it can be determined whether the imprint information is the same even when the resolution of the imprint information of the seal information acquired by the duplication possibility person detecting device 100 is different. It is also possible to determine (matching) whether or not the imprint information is the same after unifying the resolution of the imprint information included in.

(Step S105)
In step S105, the identification information matching unit 122 identifies the municipality of the seal information specified in step 104 from the registrant information (name / birth date) of the duplication potential person specified (created) in step 103. The registrant information having the same municipality personal number as the personal number (registrant identification information) is specified, and this registrant information is detected as registrant information that may be duplicated. And the identification information matching part 122 produces the information of the registrant information (name, date of birth, seal) of a possibility duplicate person.
Table 3 below is an example of information on the possibility of duplication (name, date of birth, seal) created by the seal imprint information matching unit 121.

As illustrated in Table 3, the information on the possibility of duplication (name, date of birth, seal) is composed of information such as the personal number of each municipality.
For example, in the case of Table 3, as the registrant information that is common to the name “IIII”, the date of birth “JJJJ”, and the seal information, the city A personal number is “GGGG” and the city A seal number is It shows that there is registrant information with “KKKK” and registrant information with the personal number of B town “HHHH” and the seal number of B town “LLLL”.

The identification information matching unit 122 uses the information (registrant information) of the possibility of duplication (name / birth date) created in step S103 as 1) registrant information with the same name / birth date / imprint information. 2) The information is divided into registrant information having the same name and date of birth, and each information is stored in the duplicate registration possibility person information storage unit 131 of the storage unit 130.
Registrant information with the same name and date of birth includes the case where the seal information of the seal information is different as described above, as well as the case where there is no corresponding seal information (when the corresponding seal is not registered). It is.

  In addition, here, the registrant information of the person who has the possibility of duplication (name / date of birth) is the same as 1) the registrant information with the same name / date of birth / imprint information, and 2) the name / date of birth is the same. The registrant information is stored separately. However, the registrant information (name / birth date) of potential duplicates may be stored in the order of 1) → 2). .

  Registrant information with the same name, date of birth, and seal imprint information detected in this way is considered to be registrant information that is very likely to be information of the same person. Therefore, the administrator of the registrant information only applies to registrant information (duplicate potential person information) having the same name, date of birth, and seal imprint information detected by the duplication possibility person detection device 100 of the present embodiment. By conducting a detailed survey or conducting a survey with priority over other registrant information, it is possible to efficiently detect and identify the registrant information of the same person.

In addition, information included in registrant information that is likely to be the same person (for example, items common to registrant information that is likely to be the same person in addition to name, date of birth, seal information, etc.) The registrant information manager may use it as a filtering parameter when detecting registrant information that may be duplicated from the registrant information.
Such a method is particularly effective when it is necessary to collate a large number of registrant information (detection of potential duplicates) such as a merger of many municipalities or a large-scale merger of municipalities.

Further, in the present embodiment, the registrant information has been described as registrant information of municipalities, but the present invention is not limited to this and can be widely applied.
For example, the registrant information may be information of an account holder such as a bank, and the seal information may be a seal (or signature) registered when an account is opened. Further, the registrant information has been described for natural persons, but may be a corporation. Furthermore, the name (or corporate name) included in the registrant information may include not only the current name but also a past name (former name or old corporate name). By doing in this way, even when a full name (last name) or a corporate name is changed, the same person (corporate) can be specified more accurately.

The duplication possibility person detecting device according to the embodiment of the present invention can be realized by a computer and a program, and provided by recording the program on a computer-readable recording medium. Is possible. It is also possible to provide the program through a network.
The computer system here includes software such as an OS (Operating System) and hardware such as peripheral devices.

It is the block diagram which showed the structure of the duplication possibility detection system which is embodiment of this invention. It is the flowchart which showed the process sequence of the duplication possibility person detection apparatus of FIG. It is the figure which conceptually demonstrated the process sequence which the duplication possibility person detection apparatus of FIG. 1 produces registrant information.
