[0061] [ Figure 12 ] Figure 12 This is a flowchart illustrating the personal information provision process in the fourth embodiment. Detailed Implementation

[0062] The implementation of the personal information provision system of the present invention will be described based on the diagrams. The present invention is a system for providing personal information required for using a service by a service user (hereinafter referred to as a user). Its characteristic is that it only provides the service provider with the personal information permitted by the user or the personal information required for the service, effectively preventing the provision of personal information unnecessary for the service used by the user. Furthermore, in this embodiment, the required personal information can be provided from the user to the service provider offline, thus enabling user authentication or the provision of services using personal information even in internet environments or countries with incomplete personal authentication systems.

[0063] First Implementation Method Figure 1 is a configuration diagram of the personal information providing system 1 according to the first embodiment. As shown in Figure 1, the personal information providing system 1 according to the first embodiment includes a first information terminal 10 carried by a user and a second information terminal 20 held by a service provider. In this embodiment, the first information terminal 10 and the second information terminal 20 are configured not to perform wireless communication, but they may also be configured to perform wireless communication. Furthermore, in the personal information providing system 1 according to the first embodiment, the first information terminal 10 and the second information terminal 20 may also be configured to communicate with a server (not shown).

[0064] Figure 2 This is a block diagram illustrating the configuration of the first information terminal 10 and the second information terminal 20. The first information terminal 10 is an information terminal carried by the user, such as a smartphone, tablet, or laptop computer. In this embodiment, a smartphone is used as an example for explanation. Figure 2 As shown, the first information terminal 10 includes a camera 11, a display 12, an input unit 13, a memory unit 14, and a processing unit 15.

[0065] As needed, the camera 11 can acquire the user's facial information by capturing an image of the user's face, or by capturing a card containing the user's personal information. The display 12 displays the first information code 41 containing the user's personal information on the screen. The input unit 13 operates to register the user's personal information. The memory unit 14 stores the user's personal information and stores the program used to perform the personal information provision processing of this embodiment. The arithmetic unit 15 executes the program stored in the memory unit 14 to implement the information code registration function for registering the first information code 41 containing two or more pieces of the user's personal information, and the information code prompting function for prompting the registered first information code. Furthermore, the above-mentioned program can be executed in the first information terminal 10 through an application program or in the form of an application. Hereinafter, the functions of the first information terminal 10 will be described.

[0066] The information code registration function of the first information terminal 10 generates a first information code 41 containing two or more pieces of personal information of the user, and stores the generated first information code 41 in the memory unit 14. Here, the personal information contained in the first information code 41 is not particularly limited, but examples include textual information such as the user's identification number (personal identification number), name, address, passport number, account number, driver's license number, social insurance number, date of birth, place of birth, and former surname, or biometric information such as facial image, fingerprint information, iris information, palm shape, retina, blood vessels, voice, and ear shape. Furthermore, in the first embodiment, the first information code 41 contains more personal information than is required for the service used by the user.

[0067] The information code prompting function of the first information terminal 10 is a function of prompting the first information code 41 including two or more pieces of personal information of the user registered by the information code registration function. Specifically, the information code prompting function is a function of acquiring the first information code 41 created in advance from the memory 14 and displaying the acquired first information code 41 on the screen of the display 12, thereby prompting the first information code 41 including two or more pieces of personal information of the user.

[0068] Here, the first information code 41 of the present embodiment will be described. Figure 3 is a diagram showing an example of the first information code 41. In the present embodiment, the configuration of a color QR code composed of information units of three or more colors is exemplified, but the present embodiment is not limited to this configuration, and can be a QR code (registered trademark) or a bar code composed of information units of white and black arranged in a grid pattern, or the like.

[0069] As shown in Figure 3 , the first information code 41 is a two-dimensional code in a square shape, and has an information code region 401 composed of colored information units 402 of two or more colors that are units of display information, a teaching code region 403 of teaching units 404 that are the same color as the information units 402 and have the same number of colors as the information units 402 in order to identify the colors of the information units 402, and a locator 405.

[0070] In particular, the first information code 41 has a plurality of teaching units 404 in the teaching code region 403 in order to improve the recognition accuracy of the colors of the information units 402. The types of colors of the teaching units 404 coincide with the types of colors of the information units 402, and by comparing the colors of the teaching units 404 with the colors of the information units 402, the colors of the information units 402 can be recognized with high accuracy. In particular, in a color QR code, the more the types of colors increase, the closer the hues of the respective colors become, and thus there are cases where it is difficult to properly recognize the colors of the information units 402 due to the light environment such as illumination, the printing environment of the first information code 41, the display environment of the first information code 41 on a display or the like, the fading of the printed first information code 41 over time, or the like. Even in such a case, the colors of the information units 402 can be recognized by referring to the teaching units 404, and the information of the information units 402 can be properly grasped. For example, in a case where the color information of the information units 402 is purple and it is difficult to recognize whether it is similar to red or similar to blue, in a case where the color information of the teaching units 404 that are more purple is closer to the color information of red, it can be determined that the color of the information units 402 is red. Further, the color information can be quantified as RGB values or CMY values.

[0071] The information code area 401 can record specific information composed of a certain amount of character information and / or binary information by changing the display pattern of the information unit, i.e., the information cell 402. The content of the specific information recorded by the information code area 401 is not particularly limited, and in the present embodiment, personal information including biometric authentication information for biometric authentication can be memorized. As the personal information, in addition to the biometric authentication information, a mobile phone number, a personal number, a passport number, an account number, a driver's license number, a name, a social security number, a date of birth, a place of birth, an old family name, and the like can be included. Also, as the biometric authentication information, a face image, fingerprint information, iris information, a palm shape, a retina, blood vessels, a voice, an ear shape, and the like can be included.

[0072] Further, in the first information code 41, the information code area 401 recording the specific information is composed of 3 or more colors of information cells 402, and thus the amount of information that can be recorded is increased compared to an information code composed of 2 colors of white and black. However, the data capacity that the first information code 41 can memorize is less than that of other recording media, and thus in a case where an image of the entire face is recorded at a resolution at which face authentication can be performed, there is a concern that the memory capacity of the information code area 401 composed of 4 colors of information cells 402 will be insufficient. Therefore, in the information code 40 of the present embodiment, instead of memorizing the entire face of the user, only a part of the face of the user, such as the eyes or the mouth, which is a feature point in face authentication, is memorized as a face image for face authentication, and thus it is possible to record a face image for face authentication in the first information code 41.

[0073] Next, the second information terminal 20 of the present embodiment will be described. The second information terminal 20 is an information terminal such as a smartphone, a tablet, a notebook personal computer, a desktop personal computer, a POS terminal, a dedicated terminal, and the like possessed by a service provider who provides a service, and in the present embodiment, a dedicated terminal will be described as an example. As shown in FIG. 2, the second information terminal 20 has a camera 21, a display 22, an input section 23, a memory section 24, and a computation section 25. The camera 21 reads the first information code 41 including personal information displayed on the first information terminal 10. The display 22 displays the personal information of the user on the screen. The input section 23 performs an operation for the user to set permission of the personal information provided to the second information terminal 20. The memory section 24 memorizes a program for providing personal information in the present embodiment. The computation section 25 realizes a setting function of setting the personal information for which the user has given permission, a personal information acquisition function of freely acquiring the personal information from the first information code 41 prompted by the first information terminal 10, and a display control function of controlling the display of the personal information by executing the program memorized in the memory section 24. Further, the above-described program can be executed in the second information terminal 20 by an application or in an application form. Hereinafter, each function of the second information terminal 20 will be described. Figure 2 As shown in FIG. 2, the second information terminal 20 has a camera 21, a display 22, an input section 23, a memory section 24, and a computation section 25. The camera 21 reads the first information code 41 including personal information displayed on the first information terminal 10. The display 22 displays the personal information of the user on the screen. The input section 23 performs an operation for the user to set permission of the personal information provided to the second information terminal 20. The memory section 24 memorizes a program for providing personal information in the present embodiment. The computation section 25 realizes a setting function of setting the personal information for which the user has given permission, a personal information acquisition function of freely acquiring the personal information from the first information code 41 prompted by the first information terminal 10, and a display control function of controlling the display of the personal information by executing the program memorized in the memory section 24. Further, the above-described program can be executed in the second information terminal 20 by an application or in an application form. Hereinafter, each function of the second information terminal 20 will be described.

[0074] The setting function of the second information terminal 20 is a function by which the user sets permission to provide personal information to the second information terminal 20 (service provider). In the first embodiment, as shown in FIG. 2, the setting function is a function by which the user sets permission to provide personal information to the second information terminal 20 (service provider) by displaying a screen for setting permission to provide personal information on the display 22. Figure 4 Figure 4 Figure 4

[0075] The personal information acquisition function of the second information terminal 20 is a function of reading the first information code 41 prompted by the first information terminal 10 and acquiring personal information included in the first information code 41. In the first embodiment, in particular, the personal information acquisition function is a function of acquiring only personal information permitted to be provided by the user by the setting function from two or more pieces of personal information included in the first information code 41.

[0076] The display control function of the second information terminal 20 is a function of controlling display of personal information acquired by the personal information acquisition function. In the first embodiment, in particular, since the personal information acquisition function acquires only personal information permitted to be provided by the user, the display control function directly displays all the personal information acquired by the personal information acquisition function (e.g., personal information of name, date of birth, sex, and personal number in the example shown in FIG. 3) on the display 22. Figure 4

[0077] Next, the personal information providing process of the first embodiment will be described. Figure 5 FIG. 4 is a flowchart showing the personal information providing process of the first embodiment. Further, the personal information providing process shown in FIG. 4 is a process by which the user provides personal information to the service provider in order to use various services such as administrative services, medical services, and car rental services (the same applies to the second to fourth embodiments described below). Hereinafter, before the personal information providing process is performed, the first information code 41 including two or more pieces of personal information of the user (including personal information required for the service used by the user and personal information not required) is previously memorized in the memory 14 by the information code registration function of the first information terminal 10. Figure 5

[0078] ​​​​​In step S101, self-authentication is performed in the first information terminal 10. For example, after the first information terminal 10 starts an application or an application program, first, the face of the user is imaged by the camera 11, and face authentication is performed based on the imaged face image. Note that the method of face authentication is not particularly limited, and a publicly known method can be used. Also, the face information required for face authentication can be imaged in advance by the camera 11 and stored in the storage 14.

[0079] Then, in step S102, it is determined in the first information terminal 10 whether the face authentication was successful. When the face authentication was successful, the process proceeds to step S103. On the other hand, when the face authentication was not successful, the process proceeds to step S108, and after error information is displayed on the display 12 of the first information terminal 10, the personal information providing process shown in Fig. 1 ends. Figure 5

[0080] In step S103, the user-permitted-to-provide personal information is set by the setting function of the second information terminal 20. For example, as shown in Fig. 2, the user operates the touch panel serving as the input 23, and touches the personal information that the user permits to be provided to the second information terminal 20 among the two or more pieces of personal information included in the first information code 41, whereby the user-permitted-to-provide personal information can be set. Figure 4

[0081] In step S104, the first information code 41 including personal information is prompted by the information code prompting function of the first information terminal 10. In the present embodiment, the first information terminal 10 stores the first information code 41 including two or more pieces of personal information in the storage 14 in advance, and the information code prompting function can acquire the first information code 41 stored in the storage 14 and display it on the display 12. Note that the personal information included in the first information code 41 includes not only the user-permitted-to-provide personal information in step S103, but also personal information that is not permitted to be provided.

[0082] In step S105, the first information code 41 prompted by the first information terminal 10 in step S104 is read by the personal information acquisition function of the second information terminal 20. For example, the personal information acquisition function activates the camera 21, and the camera 21 images the first information code 41 displayed on the display 12 of the first information terminal 10 by the user, whereby the first information code 41 can be read by the second information terminal 20.

[0083] ​​In step S106, the personal information of the user is acquired from the first information code 41 read in step S105 by the personal information acquisition function of the second information terminal 20. In the present embodiment, in particular, the personal information acquisition function acquires only the personal information that is permitted to be provided to the second information terminal 20 from the first information code 41 based on the setting information of the personal information set in step S103. That is, even if the first information code 41 includes personal information that is not permitted to be provided by the user, the personal information acquisition function acquires only the personal information that is permitted to be provided by the user from among the two or more pieces of personal information based on the setting information of the personal information set in step S103.

[0084] In step S107, the personal information acquired in step S106 is displayed on the display 22 by the display control function of the second information terminal 20. Here, in step S106, only the personal information that is permitted to be displayed by the user is acquired, and therefore in this step S107, only the personal information that is permitted to be displayed by the user is displayed and provided to the service user. Then, the personal information providing process shown in FIG. 6 is ended. Figure 5

[0085] As described above, the personal information providing system 1 of the first embodiment has the first information terminal 10 and the second information terminal 20, provides the personal information of the user of the first information terminal 10 to the second information terminal 20, the first information terminal 10 prompts the first information code 41 including two or more pieces of personal information, and the second information terminal 20 sets the personal information that is permitted to be provided by the user from among the two or more pieces of personal information included in the first information code 41 and displays only the personal information that is permitted to be provided by the user from among the two or more pieces of personal information included in the first information code 41 prompted by the first information terminal 10. Thus, in the personal information providing system 1 of the first embodiment, for example, in the case where the user receives administrative services, the personal information utilized by the administrative services such as the address, the facial image, and the name is provided in such a manner that the second information terminal 20 is set, and therefore in the second information terminal 20, only the personal information utilized by the administrative services from among the personal information of the user included in the first information code 41 prompted by the first information terminal 10 that is permitted to be provided by the user is acquired, and it is possible to effectively prevent the provision of the personal information that is not utilized by the administrative services to the provider of the administrative services. Also in the present embodiment, even in the case of offline, it is possible to prompt the required personal information and perform the authentication of the user or the provision of the services using the personal information. Therefore, for example, in a country where the Internet environment or the personal authentication system is not perfect, it is possible to provide the required personal information from the first information terminal 10 to the second information terminal 20 by using the personal information providing system 1 of the first embodiment and perform the authentication of the user or the provision of the services using the personal information.

[0086] ​​Next, the personal information providing system 1 of the second embodiment will be described. The personal information providing system 1 of the second embodiment has the same configuration as the personal information providing system 1 of the first embodiment, and operates in the same manner as the personal information providing system 1 of the first embodiment except for the following description.

[0087] In the second embodiment, the arithmetic unit 15 of the first information terminal 10 has a setting function for the user to set personal information to be permitted to be provided to the second information terminal 20 in addition to the functions of the first embodiment. Specifically, the setting function is to display a screen for setting personal information to be permitted to be provided to the second information terminal 20 on the display 12 of the first information terminal 10 as shown in FIG. 8. Thus, the user can operate the display 12 and the touch panel serving as the input unit 13 to set personal information to be permitted to be provided. Figure 4

[0088] Next, the personal information providing process of the second embodiment will be described. Figure 6 is a flowchart showing the personal information providing process of the second embodiment. Further, the steps S201, S202, and S208 are the same as the steps S101, S102, and S108 of the first embodiment, and thus the description thereof will be omitted.

[0089] In the step S203, the setting of the personal information to be permitted to be provided to the second information terminal 20 is performed by the user operating the first information terminal 10 using the setting function of the first information terminal 10. Specifically, the setting function first displays a setting screen for setting personal information to be permitted to be provided to the second information terminal 20 on the display 12 of the first information terminal 10 as shown in FIG. 8. The user can operate the touch panel serving as the input unit 13 to set personal information to be permitted to be provided among two or more pieces of personal information displayed on the display 12, and after selecting the personal information to be permitted to be provided, the setting function acquires the selected personal information as the personal information to be permitted to be provided to the second information terminal 20. Figure 4

[0090] In the step S204, the creation and presentation of the first information code 41 are performed by the information code presentation function of the first information terminal 10. Specifically, the information code presentation function creates the first information code 41 including only the personal information to be permitted to be provided set in the step S203, and displays the created first information code 41 on the display 12.

[0091] ​​In step S205, the first information code 41 prompted in step S204 is read by the personal information acquisition function of the second information terminal 20, and in step S206, the personal information of the user is acquired from the first information code 41 read in step S205 by the personal information acquisition function. Here, in the second embodiment, the first information code 41 contains only the personal information permitted to be provided by the user as the personal information of the user, and therefore the personal information acquisition function can acquire all the personal information contained in the first information code 41 as the personal information permitted to be provided by the user. Further, in step S207, the personal information permitted to be provided by the user acquired in step S206 is displayed on the display 22 by the display control function of the second information terminal 20. As described above, in the second embodiment, since the personal information permitted to be provided by the user is contained only in the first information code 41, only the personal information permitted to be provided by the user is provided to the service provider in step S207.

[0092] As described above, in the personal information providing system 1 of the second embodiment, the personal information permitted to be provided by the user is set by the first information terminal 10, and the first information code 41 containing only the personal information permitted to be provided is prompted, and therefore the second information terminal 20 can provide only the personal information permitted to be provided by the user to the second information terminal 20 (or the service provider) by directly displaying all the personal information contained in the first information code prompted by the first information terminal 10. In particular, in the second embodiment, the user can operate only the first information terminal 10, and therefore the convenience of the user can be improved.

[0093] Third Embodiment Next, the personal information providing system 1 of the third embodiment will be described. The personal information providing system 1 of the third embodiment has the same configuration as the personal information providing system 1 of the first embodiment, and operates in the same manner as the personal information providing system 1 of the first embodiment except for the following description.

[0094] In the first information terminal 10 of the third embodiment, the memory 14 associates the first information code 41 containing one or more pieces of personal information required for the service provided by the second information terminal 20 with the service information showing the service described above, and stores them in association with each service. For example, the memory 14 can be configured to store the first information code 41 containing the personal information required for the administrative service such as the address, the face image, the name, and the like in association with the administrative service information, and store the first information code 41 containing the personal information required for the medical service such as the health insurance card number in association with the medical service information, and store the first information code 41 containing the personal information required for the car rental service such as the driver's license number in association with the car rental service information.

[0095] Further, in the first information terminal 10 of the third embodiment, the information code registration function of the arithmetic unit 15 creates the first information code 41 including one or two or more pieces of personal information used for each service, and associates the first information code 41 with the service information showing the above-described service, and stores the first information code 41 in the storage unit 14. For example, in the above-described example, the information code registration function creates the first information code 41 including the personal information of the address, the face image, the name, and the like required for the administrative service, and stores the first information code 41 in the storage unit 14 in association with the administrative service information. Further, the information code registration function creates the first information code 41 including the personal information of the health insurance card number and the like required for the medical service, and stores the first information code 41 in the storage unit 14 in association with the medical service information. Further, the information code registration function creates the first information code 41 including the personal information of the driver's license number and the like required for the car rental service, and stores the first information code 41 in the storage unit 14 in association with the car rental service information.

[0096] Further, in the third embodiment, the information code prompting function of the arithmetic unit 15 can prompt the first information code 41 corresponding to the service used by the user. For example, as shown in FIG. 7, the information code prompting function displays a screen for selecting the service to be used by the user on the display 12. The user can operate the touch panel serving as the input unit 13 to display the service to be used by the user from among the plurality of services displayed on the display 12. After the user selects the service, the information code prompting function displays the first information code 41 corresponding to the selected service from among the plurality of first information codes 41 stored in the storage unit 14 on the display 12. Note that FIG. 7 is a diagram showing an example of the selection screen of the service in the third embodiment.

[0097] Next, the information code registration processing of the third embodiment will be described with reference to the flowchart shown in FIG. 8. Figure 8 The information code registration processing of the third embodiment will be described. Figure 8 FIG. 8 is a flowchart showing the information code registration processing of the third embodiment. Further, the information code registration processing of the present embodiment is performed by the user using the first information terminal 10.

[0098] In step S301, the registration of two or more pieces of personal information is performed by the information code registration function of the first information terminal 10. For example, the information code registration function can be configured to display a screen for the user to register the personal information on the display 12, and to input the personal information from the user via the input unit 13. The registered personal information is stored in the storage unit 14 of the first information terminal 10.

[0099] In step S302, the registration of the service used by the user is performed by the information code registration function. For example, the information code registration function can be configured to display a screen for the user to register the service used by the user on the display 12, and to input the service used by the user. The registered information of the service used is stored in the storage unit 14 of the first information terminal 10.

[0100] In step S303, by the information code registration function, the first information code 41 containing only the personal information used by the service registered in step S302 among the two or more pieces of personal information registered in step S301 is created for each service registered in step S302, and is stored in the storage section 14. For example, the information code registration function first displays a screen for selecting the service for which the first information code 41 is to be created among the services registered in step S302 on the display 12, and the user selects the service for which the first information code 41 is to be created. Next, the information code registration function displays a screen for selecting the personal information used by the service selected by the user among the personal information registered in step S301 on the display 12, and the user selects the personal information used by the service selected by the user. Thus, the information code registration function can grasp the personal information used by each service, can create the first information code 41 containing only the personal information used by the service, and can store it in the storage section 14.

[0101] Next, the personal information provision processing of the third embodiment will be described. Figure 9 is a flowchart showing the personal information registration processing of the third embodiment. Further, steps S401, S402, and S408 are the same as steps S101, S102, and S108 of the first embodiment, and thus the description thereof will be omitted.

[0102] In step S403, the service information of the service used by the user is acquired by the information code presentation function of the first information terminal 10. Specifically, as shown in FIG. 7, the information code presentation function can display a screen for selecting the service used by the user on the display 12. The user can operate the touch panel serving as the input section 13, and the service used by the user is displayed among the plurality of services displayed on the display 12, and after the user selects the service, the information code presentation function acquires the service information showing the selected service.

[0103] In step S404, the first information code 41 corresponding to the service information acquired in step S403 is presented by the information code presentation function. In the third embodiment, the first information code 41 containing only the personal information used by the service is pre-stored in the storage section 14 in association with the service information, and thus the information code presentation function acquires the first information code 41 corresponding to the service information acquired in step S404 from the storage section 14, and displays it on the display 12.

[0104] Then, in step S405, the first information code 41 prompted by the first information terminal 10 is read by the personal information acquisition function of the second information terminal 20, and in step S406, the personal information including the read first information code 41 is acquired by the personal information acquisition function. Then, in step S407, the personal information acquired in step S406 is displayed on the display 22 by the display control function of the second information terminal 20. Thus, in the third embodiment, the first information code 41 read by the second information terminal 20 is an information code including the personal information required for the service used by the user, and therefore only the personal information required for the service used by the user is provided to the second information terminal 20 (the service provider).

[0105] As described above, in the third embodiment, the first information terminal 10 memorizes a plurality of first information codes 41 including only the personal information required for each service in association with the service information showing the services for each service, acquires the service information of the service used by the user, and prompts the first information code 41 corresponding to the service information based on the service information. Also, the second information terminal 20 displays the personal information included in the first information code 41 prompted by the first information terminal 10. Thus, the personal information providing system 1 of the third embodiment can provide only the personal information required for the service used by the user to the second information terminal 20 (or the service provider).

[0106] Fourth Embodiment Next, a fourth embodiment of the present application will be described. FIG. 10 is a configuration diagram showing a personal information providing system la of the fourth embodiment. As shown in FIG. 10, in the fourth embodiment, in addition to the first information terminal 10a and the second information terminal 20a, a server 30 capable of communicating with the first information terminal 10a and the second information terminal 20a is provided. Further, the first information terminal 10a and the second information terminal 20a are used in an environment capable of using network communication such as the Internet line 2, and the first information terminal 10a, the second information terminal 20a, and the server 30 can communicate with each other by wireless communication or wired communication.

[0107] Figure 11 is a configuration diagram showing the first information terminal 10a and the second information terminal 20a of the fourth embodiment. The first information terminal 10a of the fourth embodiment is also an information terminal such as a smartphone, a tablet, a notebook personal computer, and the like as in the first embodiment, and in the present embodiment, a smartphone will be described as an example. The first information terminal 10a is configured to include a display 21, a display control function, a first information code reading function, a service information acquisition function, and a service information display function as in the first embodiment. Figure 11As shown, the first information terminal 10a has a communication section 16 capable of network communication via the Internet line 2. Also, in the first information terminal 10a of the fourth embodiment, the information code presentation function of the operation section 15 presents different information codes depending on whether or not network communication is possible via the communication section 16. Specifically, the information code presentation function presents the second information code 42 containing identification information for identifying the user and service information showing the service used by the user in the case of online in which network communication is possible, and presents the first information code 41 containing personal information of the user in the case of offline in which network communication is not possible.

[0108] Also, in the fourth embodiment, the second information terminal 20a also has a communication section 26 like the first information terminal 10a. Further, in the fourth embodiment, the second information terminal 20a is, like the first embodiment, an information terminal such as a smartphone, a tablet, a notebook personal computer, a desktop personal computer, a POS terminal, a dedicated terminal, or the like held by a service provider, and in the present embodiment, a smartphone is described as an example. The communication section 26 can receive personal information of the user memorized in the server 30 from the server 30 via the Internet line 2 by communicating with the server 30 in an environment in which network communication is possible. Also, in the second information terminal 20a of the fourth embodiment, the personal information acquisition function of the operation section 25 acquires personal information from the first information code 41 presented by the first information terminal 10a in the case of offline, and acquires identification information of the user and service information from the second information code 42 presented by the first information terminal 10a in the case of online, and transmits the acquired identification information of the user and service information to the server 30, thereby acquiring personal information corresponding to the transmitted identification information of the user and service information from the server 30.

[0109] The server 30 is provided on the Internet line 2 and is capable of communication with at least the second information terminal 20a. The server 30 has a database (not shown) that memorizes personal information of each user required for each service for each service and each user. That is, the personal information of the user is memorized with the identification information of the user and the service information as keys, and the server 30 can provide only the personal information required for the service used by the user to the second information terminal 20a based on the acquired identification information of the user and service information by acquiring the identification information of the user and service information from the second information terminal 20a.

[0110] Next, the personal information provision processing of the fourth embodiment will be described. Figure 12is a flowchart showing the personal information providing process of the fourth embodiment. Further, steps S501, S502, and S508 are the same as steps S101, S102, and S108 of the first embodiment, and thus the description thereof is omitted. Also, hereinafter, before the personal information providing process is performed, the first information code 41 including two or more pieces of personal information of the user (including personal information required for the service used by the user and personal information not required) and the identification information for identifying the user are pre-stored in the storage 14 by the information code registration function of the first information terminal 10.

[0111] In step S503, whether or not it is offline is determined by the information code presentation function of the first information terminal 10a. Further, the determination of whether or not it is offline can use a publicly known method. In the case of offline, step S504 is entered, and in the case of online, step S509 is entered.

[0112] In steps S504 to S508, it is offline, and thus the personal information is provided to the second information terminal 20a by the same method as the first embodiment. That is, the user sets the personal information which the user permits to be provided using the second information terminal 20a (step S504), and presents the first information code 41 including two or more pieces of personal information of the user using the first information terminal 10a (step S505). Thereby, in the second information terminal 20a, the first information code 41 is read (step S506), only the personal information which is permitted to be provided among the personal information included in the first information code 41 is acquired (step S507), and the personal information which is permitted to be provided is displayed on the display 22 of the second information terminal 20a (step S508).

[0113] On the other hand, in steps S509 to S515, it is online, and thus the second information terminal 20a acquires the personal information from the server 30 and displays it. Specifically, first, in step S509, the service information showing the service used by the user is acquired by the information code presentation function of the first information terminal 10 in the same manner as step S403 of Figure 9 Then, in step S510, the second information code 42 including the identification information of the user and the service information is presented by the information code presentation function. That is, the information code presentation function creates the second information code 42 including the identification information of the user and the service information based on the identification information of the user stored in the storage 14 and the service information acquired in step S509, and displays it on the display 22.

[0114] Next, in step S511, reading of the second information code 42 prompted in step S510 is performed by the personal information acquisition function of the second information terminal 20a, and in step S512, the identification information and the service information of the user are acquired from the second information code 42 read in step S511 by the personal information acquisition function. Then, in step S513, the identification information and the service information of the user acquired in step S512 are transmitted to the server 30 by the personal information acquisition function.

[0115] In step S514, the personal information of the user required for the service is extracted from the database by the server 30 based on the identification information and the service information of the user received from the second information terminal 20 in step S513, and is transmitted to the second information terminal 20a. Thus, the personal information acquisition function of the second information terminal 20a can acquire the personal information of the user required for the service used by the user from the server 30. Then, in step S515, the personal information acquired from the server 30 in step S514 is displayed on the display 22 by the information display function of the second information terminal 20a. Further, the personal information transmitted from the server 30 to the second information terminal 20a can include the same personal information as that included in the first information code 41, and can include personal information having a larger data capacity, such as an image of the entire face, which cannot be memorized by the memory capacity of the first information code 41.

[0116] As described above, in the personal information providing system la of the fourth embodiment, the first information terminal 10a, the second information terminal 20a, and the server 30 are provided, and in the offline case, the user sets the personal information to be provided to the second information terminal 20a, and the first information code 41 including the personal information is prompted in the first information terminal 10a, whereby the service provider can acquire the personal information permitted to be provided by the user in the second information terminal 20a. Also, in the online case, the user uses the first information terminal 10a to select a service to be used by the user, and the second information code 42 including the identification information of the user and the service information is prompted, whereby the service provider can acquire the identification information of the user and the service information in the second information terminal 20a, and based on the acquired identification information of the user and the service information, the server 30 can acquire only the personal information of the user required for the service to be used by the user. Thus, in the fourth embodiment, only the personal information of the user permitted to be provided by the user, or the personal information of the user required for the service is provided to the service provider, and thus it is possible to effectively prevent the personal information irrelevant to the service from being provided. Also, in the personal information providing system la of the fourth embodiment, in the online case, the personal information of the user can be acquired from the server 30, and thus it is possible to provide the service provider with the personal information having a larger memory capacity than the first information code 41. For example, even in the case where the face image of the user cannot be memorized in the first information code 41 due to the memory capacity, in the online case, by providing the face information of the user from the server, the service provider can confirm whether the user in front of the user and the user of the personal information are the same person from the face image of the user.
