  FIG. 8 and FIG. 9 are operation flowcharts showing the operations from the application for providing the location information of the provider to the notification of the personal identification number to the recipient.

  First, the provider A having the mobile phone 4 requests transmission of an application screen for applying for provision of its own location information (Step 100).

  In the IP server 1, in response to the received request, the guidance processing unit 15 transmits an application screen as a response to the mobile phone 4 (Step 101).

  The mobile phone 4 receives the application screen, and in accordance with the instructions displayed on the screen, writes the email address of the provider A and the email address of the recipient B who provides his / her location information, and transmits it to the IP server 1 (Step 102). In the following description, it is assumed that the email address of provider A is “a3@mail.ne.jp” and the email address of recipient B is “b3@mail.ne.jp”.

  In the IP server 1, the guidance processing unit 15 receives application information, that is, the mail address of the provider A and the mail address of the recipient B, and the user identifier converted from the unique identifier of the mobile phone 4 by the gateway server 2. The information is received and the information is acquired (Step 103). Further, a guidance screen for the recipient B is created, and the guidance screen identifier for the recipient, which is an identifier of the guidance screen, is used as the acquired provider user identifier, provider email address, and recipient email address. At the same time, the data is transmitted to the database update unit (Step 104). Here, it is assumed that the user identifier of the provider A is “aaa” and the guide screen identifier for the provider, which is the identifier of the guide screen for the provider B, is “gb3”.

  Next, when the database update unit 18 receives the provider's email address, the provider's user identifier, the recipient's email address, and the recipient's guidance screen identifier, it adds a new record and verifies the record. A number is generated (Step 105). Here, it is assumed that the generated personal identification number is “1234”.

  Then, the database update unit 18 describes the generated personal identification number in the personal identification number field of the added record, describes the email address of the provider A in the provider email address field, and provides the provider A in the provider user identifier field. The recipient's email address field describes the recipient B's email address, and the recipient's guide screen identifier field describes the provider B's recipient screen identifier. (Step 106).

  More specifically, the personal identification number “1234” is described in the personal identification number field of one record of the authentication database 17, and the email address “a3@mail.ne.jp” of the provider A is provided in the provider email address field. "Is described, the provider user identifier field is the user identifier" aaa "of provider A, and the recipient email address field is the email address" b3@mail.ne.jp "of recipient B The provider's guide screen identifier “gb3” for provider B is described in the provider's guide screen identifier field. FIG. 10 is a diagram showing the update status of the authentication database 17 in this case.

  When the update process of the authentication database 17 is completed, the mail generation unit generates a confirmation e-mail to be notified to the recipient B (Step 107). In this confirmation e-mail, a link screen in which the guide screen for the recipient B including the guide screen identifier for the recipient is set as a link destination and the recipient B who has received the email is set in the email By pressing, the guidance screen for the recipient B is linked. Then, the generated electronic mail is transmitted to the mail address of the recipient B (Step 108). In this description, since the e-mail transmission destination address, that is, the mail address of the recipient B is “b3@mail.ne.jp”, “b3@mail.ne.jp” is transmitted as the transmission destination address. .

  The recipient B's mobile phone 5 receives the confirmation mail (Step 109). Then, the link destination set in the e-mail is accessed (Step 110).

  In response to the received request, the IP server 1 transmits a recipient guidance screen dedicated to the recipient B corresponding to the recipient guidance screen identifier (Step 111).

  The mobile phone 5 of the recipient B receives the recipient guidance screen (Step 112), determines whether or not to receive provision of location information, and transmits consent information (Step 113). For example, if the provision of the location information is accepted, “Yes” displayed on the screen is selected.

  In the IP server 1 that has received the consent information of the provider B, the guidance processing unit acquires the user identifier of the provider B converted from the unique identifier of the mobile phone 5 by the gateway server 2 (Step 114). Here, the acquired user identifier of the recipient B is “bbb”.

  The database update unit 18 describes the acquired user identifier of the recipient B in the recipient user identifier field of the record having the guide screen identifier for the recipient (Step 115).

  More specifically, since the information screen identifier for the recipient B of the recipient B is “gb3”, the acquired recipient B's identifier field of the record in which “gb3” is written is displayed. Enter the user identifier "bbb". FIG. 11 is a diagram showing the update status of the authentication database 17 in this case.

  Next, when the update process of the authentication database 17 is completed, the mail generation unit generates a personal identification number notification email for notifying the provider A of the personal identification number (Step 116). In this personal identification number notification e-mail, the personal identification number described in the personal identification number field of the record describing the user identifier of the recipient B is described. Then, the generated electronic mail is transmitted to the mail address of the provider A (Step 117). More specifically, the password number described in the password notification email is “1234”. The e-mail transmission destination address, that is, the mail address of the provider A is “a3@mail.ne.jp”, and “a3@mail.ne.jp” is transmitted as the transmission destination address.

  The mobile phone 4 of the provider A receives the personal identification number notification mail (Step 118). Then, the provided personal identification number is notified to the recipient B by means of telephone or the like (Step 119).

  The recipient B obtains the personal identification number from the provider B by means such as a telephone (Step 120).

Next, an operation until the recipient B acquires the location information of the provider A will be described.
FIG. 12 is an operation flowchart showing an operation until the recipient B acquires the location information of the provider A.

  First, the provider B requests the provision guidance screen from the IP server 1 in order to acquire the location information of the provider A (Step 200).

  In the IP server 1, in response to the received request, the guidance processing unit 15 transmits the provided guidance screen as a response to the mobile phone 4 (Step 201).

  The mobile phone 4 receives the application screen (Step 202), writes the personal identification number in accordance with the instruction displayed on the screen, and transmits it to the IP server 1 (Step 203). Here, since the personal identification number is “1234”, “1234” is transmitted as the personal identification number.

  In the IP server 1, the guidance processing unit 15 receives the personal identification number and the user identifier converted from the unique identifier of the mobile phone 4 by the gateway server 2 (Step 204), and sends these pieces of information to the authentication unit processing unit 20. Send.

  The authentication unit processing unit 20 searches the authentication database 17 for a record in which the received personal identification number is described. Then, the user identifier described in the recipient user identifier field of the corresponding record is collated with the acquired user identifier. If the user identifier described in the record matches the acquired user identifier, it is determined that the user is a recipient who has been authorized to provide location information by the provider (Step 205). ). In this case, the user identifier described in the provider user identifier field of the record is acquired (Step 206), and the position information corresponding to the user identifier is acquired from the position information database (Step 207). Then, the acquired position information is transmitted to the recipient B (Step 208).

  For example, when the code number received by the authentication unit processing unit 20 is “1234” and the recipient user identifier is “bbb”, the code number and the recipient who are described in the authentication database 17 of FIG. User identifiers match. In this case, it is determined that the recipient who has been authorized by the provider is requesting the location information of the provider.

  On the other hand, if they do not match, it is determined that the provider is not normally permitted to provide location information from the provider, and an error is transmitted (Step 206).

  The recipient's mobile phone 5 receives the location information (Step 210), and the location information is displayed on the mobile phone 5 (Step 211).

  As described above, the present invention uses the personal identification number and the identification information (user identifier) of the recipient's mobile phone when requesting the location information from the recipient. It has the effect of preventing the leakage of unexpected location information such as mistakes when specifying the provider, and enhancing the security effect.

  A second embodiment will be described.

In the first embodiment, the authentication system in which the position information is provided only to the recipient who is permitted by the position information provider has been described.
However, the provider is uneasy about whether the location information is correctly transmitted to the recipient. Further, even if the provider is officially permitted by the provider, there is a case where the location information is not desired to be provided for some reason. Further, when the recipient's mobile phone and password are passed on to a malicious person due to theft or the like, it is inconvenient if the provider has no means of knowing that location information has been provided.

  Therefore, in the second embodiment, there is provided a means for notifying the provider that the location information is provided while the location information of the provider is provided to the recipient. .

  In order to achieve the above feature, as shown in FIG. 13, the IP server 1 is provided with a monitoring unit that monitors the transmission of the position information to the recipient, and while the position information is being transmitted, the monitoring unit 90 Position information transmission information indicating that the position information is transmitted to the provider's mobile phone is transmitted.

  On the other hand, when the mobile phone receives the position information transmission information described above, the mobile phone is provided with a notification unit 91 that notifies the provider that the position information is being transmitted to the recipient as shown in FIG. For example, the notification unit displays an icon on the display or generates a warning sound as shown in FIG.

  With such a configuration, the provider can know that his / her position information is transmitted to a third party including the recipient who has been authorized.

A third embodiment will be described.
The third embodiment is characterized in that, in the first embodiment, the provider can set in advance the permission time for permitting the recipient to provide the location information.

  In order to achieve the above characteristics, as shown in FIG. 16, a field in which the permitted time is described is provided on the authentication database 17 of the IP server 1. Then, when the provider makes an application, the permission time is acquired together with the e-mail address and the like, and is written in the authentication database 17.

  Then, as shown in FIG. 17, the timer 100 of the IP server 1 counts the time from the start of transmission of the position information, and when the permission time elapses, the authentication processing unit 20 stops transmitting the position information.

  With this configuration, it is possible to limit transmission of important position information.

A fourth embodiment will be described.
In the fourth embodiment, the provider's location information provision application is stored in the provider's mobile phone, and the provider is notified of the location information provision application by display or the like. It is characterized by calling attention.

  In order to achieve the above characteristics, the mobile phone 4 adds a location information provision application output from the service processing unit 75 as shown in FIG. 18 in addition to the configuration of the mobile phone 4 of the first embodiment. If the storage unit 100 stores the location information provision application information indicating that the location information has been stored, and the storage unit 100 stores the location information provision application, the provider is notified that the location information provision application has been made. A notification unit 101.

  Further, the mobile phone 4 has a storage deletion unit 102 that deletes the location information provision application information from the storage unit 100 when the location information provision application is canceled.

  In the above configuration, first, when the application for providing the location information of the provider is transmitted to the IP server 1, the service processing unit 75 stores the location information provision application information indicating that the location information provision application has been made. To store. The notification unit 101 monitors the storage unit 100 and, when the location information provision application information is stored, for example, displays an icon indicating that the location information provision application has been made on the display 71 as in FIG. To do.

  In addition, when the location information provision application has conditions such as a time limit and a valid period, for example, the service processing unit 75 stores the location information provision application information including the cancellation condition in the storage unit 100. . In this case, the storage deletion unit 102 reads the release condition such as the time limit of the position information provision application information and the validity period, and deletes the position information provision application information from the storage unit 100 when the release condition is satisfied. Then, the notification unit 101 stops displaying icons and the like that have been displayed so far, and notifies the provider that the application for providing location information has been cancelled.

  With this configuration, the provider is always notified that the application for providing location information has been made, so the provider forgets that the application for providing location information has been made, and the location is unknown without the provider's knowledge. Information is not sent to the recipient.

  Further, when the application for providing location information is canceled, the provider is notified that the application has been canceled, so there is no possibility that the application for providing location information is mistaken as valid.

Although the description of the embodiment has been completed above, the above-described embodiments can be combined in a timely manner. For example, a configuration in which the second, third, and fourth embodiments are added to the first embodiment is also possible.
