=== Configurations of the operator terminal 4 and the user terminal 5 ===
FIG. 10 is a diagram illustrating a hardware configuration of an information device used for the provider terminal 4 and the user terminal 5. The business entity terminal 4 and the user terminal 5 read the program stored in the storage device 41 such as a hard disk into the memory 42 and execute it by the CPU 43 that is an arithmetic device. Further, the business entity terminal 4 and the user terminal 5 are provided with an input / output interface 44 such as various keyboards, buttons, and a display. Moreover, the provider terminal 4 and the user terminal 5 include a communication interface 45 for connecting to a wide area network.

  Further, the business entity terminal 4 and the user terminal 5 include a biometric information reading unit 46 that reads biometric information. In this embodiment, a fingerprint sensor is used as the biological information reading unit 46, but sensors such as an iris, voice, writing pressure, and vein may be used.

  The business entity terminal 4 reads out a program stored in a storage device 41 such as a hard disk into the memory 42 and executes it by the CPU 13, so that functions such as a screen control unit 51 and an input information transmission unit 52 are performed as shown in FIG. To realize.

  The screen control unit 51 outputs a guidance screen that guides the input of search condition information such as an operator name, a password, and biometric information. In accordance with the guidance screen, the user operates the input / output interface 44 to input a business type name, a business name, a personal identification number, and biometric information.

  The input information transmission unit 52 transmits the business type code corresponding to the input business type name, the business code corresponding to the input business name, the personal identification number, and the biometric information (here, fingerprint) to the search server 2.

  In addition, if the business entity terminal 4 is a terminal dedicated to a specific business operator, it is not necessary to accept input of the type of business and the business operator. Further, if the business terminal 4 is a terminal dedicated to a specific type of business, for example, “banking business”, it is not necessary to accept the selection of the business.

The browsing processing unit 61 transmits the business type code, business code, password, and biometric information of the business operator input by the user to the search server 2 via the communication control unit 62.

=== Search processing ===
Next, the search process will be described with reference to the flowchart of FIG. The information acquisition unit 21 acquires search condition information such as biometric information, a personal identification number, a business type code, and a company code from the user terminal 5 or the company terminal 4 and stores it in the memory 42 (step S100). The biometric information extraction unit 22 extracts the user number from the biometric information search key table 31 by using the business type code, the company code, and the code number acquired as the search condition information as keys (step S101).

  Next, the search processing unit 23 extracts biometric information associated with the same user number as the user number extracted by the biometric information extraction unit 22 from the biometric information table 32 (step S102). The search processing unit 23 compares the biological information extracted in step S102 with the biological information acquired as search condition information (step S103). If the biometric information extracted in step S102 matches the biometric information input as the search condition information (step S104; YES), the search processing unit 23 stores the user number and biometric information associated with this biometric information. The body part information is read from the biological information table 32 (step S105). On the other hand, if the biometric information read in step S102 does not match the biometric information acquired as the search condition information (step S104; NO), the search processing unit 23 indicates that the user is not registered. The data is transmitted to the user terminal 5 or the operator terminal 4 (step S106).

  The search processing unit 23 reads the contract detail information from the contract detail table 33 by using the industry code, the company code, which is the search condition information, and the user number and body part read in step S105 as keys (step S107). . Next, the search processing unit 23 provides services such as personal information stored in the personal information table 34, business name stored in the business code master 35, business information stored in the business code master 36, etc. Information necessary to do this is read (step S108).

  The output processing unit 24 adds the personal information read from the personal information table 34 and the business information read from the business type code master 35 and the business code master 36 to the search result of the search processing unit 23 to provide the business server. 3 (step S109).

  A specific example of the search process will be described with reference to FIG. In this example, the search condition information acquired by the information acquisition unit 21 is biometric information “010010101001...”, Personal identification number “1234”, business type code “0001”, and business operator code “0012”.

  The biometric information extraction unit 22 extracts the user number from the biometric information search key table 31 using the acquired personal identification number “1234”, the business type code “0001”, and the business operator code “0012” as keys. By this process, the number of users to be searched is narrowed down to 1 / 10,000 or more. The ratio of narrowing down depends on the number of digits in the PIN code, the number of digits in the industry code, and the number of digits in the business operator code.

  In the example of FIG. 14, as a result of narrowing down using the industry code “0001”, the company code “0012”, and the personal identification number “1234” as keys, the user (user number: user number: 112233455), the user (user number: 2233445566),... In the fifth line is extracted.

  The search processing unit 23 extracts data that matches the user number extracted by the biometric information extraction unit 22 from the biometric information table 32. In the example of FIG. 14, the search processing unit 23 extracts the biometric information associated with the user number “11223334555”, the user number “22333445566”,.

  The search processing unit 23 compares the extracted biological information with the biological information “0100101001...” Input by the user. In the example of FIG. 14, the biometric information “0100101001...” Input by the user matches the data in the second row of the biometric information table 32, that is, the body part “middle finger” of the user number “11223345455”.

  The search processing unit 23 uses the detected user number “1122334455”, the body part “middle finger”, the business type code “0001” acquired as the search condition, and the business operator code “0012” as a key for the contract detailed information from the contract detailed information table. Is read. In the example of FIG. 14, the branch name “Omori branch”, the deposit type “ordinary”, and the account number for the business type code “0001”, the company code “0012”, the user number “11223345455”, and the body part “middle finger”. Read “0012345”.

  By the way, although one set of contract detailed information is associated with the body part “middle finger” of the user number “1122334455”, a plurality of pieces of contract detailed information are associated with the body part of a certain user. In some cases. For example, the body part “thumb” of the user number “1122334455” has the deposit name “current account” with the account number “0054321” and the deposit type “periodic account” with the account number “112234” in the branch name “Shin-Kawasaki branch”. And the deposit type “ordinary account” of the account number “667789” are associated with each other. In this case, three sets of detailed contract information are read out.

  As described above, in the search system 1 to which the present invention is applied, when searching for biometric information input from a user, the search server 2 uses the provider's attribute information such as the provider code and password, and the user. Using the attribute information, the users to be searched are narrowed down. Biometric information collation is a process with a large amount of calculation, but the amount of calculation is reduced by narrowing down search information.

  In the search system 1 to which the present invention is applied, the search server 2 can specify detailed information to be provided to the user depending on which part of the body the biological information input from the user corresponds to. Further, the search server 2 stores personal information of the user, and can select personal information necessary for a service provided to the user.

  Although the present embodiment has been described above, the above embodiment is for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.

  For example, in the above embodiment, a personal identification number is used as the user attribute information. However, the user's sex, age, etc. may be used instead of the personal identification number. If attribute information such as gender and age is recognized from the face image of the user, manual input by the user is unnecessary.
