Depending on the situation, changes in the friendship situation may be missed, so it is not activated by a child's operation, but may be set to be activated automatically when the power is turned on etc. preferable. In the second embodiment, it may be activated by the operation of the guardian, but in this case as well, the power is turned on in order to avoid missing the change in the friendship situation due to the forgotten operation. It is preferable to set it so that it is automatically activated at a predetermined timing.

  In the following description of the flowchart, the description will be given on the assumption of the configuration of the first embodiment, and different parts in the second embodiment will be supplemented as appropriate. The login processing unit 11, the login information storage unit 12, the information acquisition unit 13, the friend number calculation unit 14, the friend information storage unit 15, the text data analysis unit 16, the bullying rule storage unit 17, and the notification transmission unit 18 in the first embodiment.

  When the friendship status detection program according to the present invention is started in the user (child) terminal 10, the login processing unit 11 is necessary for logging in to the user (child) account of the SNS server 20 such as the user ID and password. Information is read from the login information storage unit 12 (S01), and the information is transmitted to the SNS server 20 as a login request (S02). As a premise for executing such processing, the login information storage unit 12 needs to store a user ID, a password, and the like used by a user (child) to log in to the account of the SNS server 20 in advance. is there.

  In addition to the timing at which the friendship status detection program according to the present invention is activated, the timing at which the login request is transmitted in this way is set at a predetermined interval (for example, once a day every day) during the program activation. The time may be repeatedly transmitted.

  In the SNS server 20 that has received the request, the user (child) is authenticated by verifying the user ID and password stored in the user information storage unit 21, and the access is authenticated by the user (child). In this case, login is permitted, and a notification that login is successful is transmitted to the user (child) terminal 10. If the user is not authenticated, an error notification is transmitted.

  In the second embodiment, the user authentication request is transmitted from the user (guardian) terminal. However, if the combination of the user ID and the password matches, the user (child) himself permits it in advance. Log-in is permitted even if the access is not from a terminal owned by the user (child) himself / herself.

  The user (child) terminal 10 that has received the notification from the SNS server 20 confirms whether or not the login is permitted from the type of notification (S03), and if the login is not permitted, informs that the login has failed. A notification is transmitted to the user (guardian) terminal 30 (S04). The method of sending notification to the user (guardian) terminal 30 is not particularly limited, but the address that can be received by the user (guardian) terminal 30 stored in advance in the notification address storage unit 19 is read out. The notification may be transmitted from the notification transmission unit 18 by e-mail or SNS direct message.

  Note that it is not essential to send a notification to the user (guardian) terminal 30 when the login fails here, but this is promptly performed when the child has changed the password without telling the guardian. In order to detect, it is preferable to have a configuration for sending such a notification.

  On the other hand, if the login is permitted, the information acquisition unit 13 transmits a request for transmitting predetermined information from the account of the logged-in user (child) to the SNS server 20 (S05).

  Regarding the processing flow for detecting the sign of bullying with the information acquired from the SNS server 20 thereafter, two patterns will be described using the flowcharts of FIGS. 6 and 7. FIG. 6 shows a pattern in which information about a friend and text data such as a message are simultaneously acquired as information for detecting a sign of bullying. FIG. 7 shows a pattern in which text data is acquired only when necessary after acquiring information about a friend and making a determination.

  In the first pattern shown in the flowchart of FIG. 6, in S05 of the flowchart of FIG. 5, the SNS server 20 is combined with the list of friends (users who are mutually approved in SNS) of the logged-in user (child). Requests transmission of text data such as comments written in the (child) account and messages sent and received by the user (child). In the SNS server 20 that has received the request, the information read from the user information storage unit 21 is returned, and the user (child) terminal 10 acquires the information (S06).

  Here, the friend list received by the user (child) terminal 10 needs to be the latest friend list in the user (child) account. The text data received by the user (child) terminal 10 may be all messages or the like. However, in order to detect the most recent change in the situation, the text data received after the previous text message is received. It is preferable to limit the target to comments and messages written in the user (child) account.

  The number-of-friends calculation unit 14 reads out information on the latest number of friends updated during the previous calculation of the number of friends from the number-of-friends storage unit 15 and compares it with the latest number of friends counted from the friend list acquired from the SNS server 20. Then, the increase / decrease is calculated (S07). If the calculated increase / decrease in the number of friends does not match the predetermined condition for determining that the number of friends is rapidly decreasing (S08), the processing is terminated as it is without signs of bullying, If the condition is met, proceed to the next step.

  Note that the information acquired from the SNS server 20 to determine the increase / decrease in the number of friends is not limited to the friend list, and it is efficient to obtain the latest number of friends if possible. is there. In any case, the number of friends specified by the information acquired from the SNS server 20 is recognized as the current number of friends in the user (child) account, and information on the number of friends stored in the number-of-friends storage unit 15 is stored. It is updated to reflect this.

  Further, the number of friends stored in the friend information storage unit compared with the latest number of friends specified by the information acquired from the SNS server 20 is not limited to the latest number of friends. As long as it relates to the number of past friends that can be used as a reference, the average value of the past three times, the minimum value in the past month, or the like may be employed. When such a value is adopted as the reference value, when the information regarding the number of friends stored in the number-of-friends storage unit 15 is updated using the number of the latest friends, the number of the latest friends is simply newly written. Instead, the reference value calculated by reflecting the latest number of friends is written.

  If the number of friends matches, the text data analysis unit 16 analyzes the text data acquired from the SNS server 20 by a method such as collation with the bullying rule storage unit 17 (S09). Then, it is confirmed whether there is any writing indicating a sign of bullying (S10). Here, the method of analyzing the text data is not particularly limited. For example, keywords that suggest bullying (such as “baka” and “dead”) are registered in the bullying rule storage unit 17, and these keywords If it appears above a certain standard, it may be determined that there is a sign of bullying.

  If it is determined that there is no writing that shows signs of bullying, the process is terminated as if there are no signs of bullying, but if it is determined that there is writing that shows signs of bullying, there are no signs of bullying. As a result, a predetermined process is executed (S11).

  In the first embodiment, the notification transmission unit 18 reads an address such as an e-mail address for receiving a notification at the user (guardian) terminal 30 from the notification address storage unit 19 and designates this address as a destination. A notification notifying the user (guardian) that a sign of bullying has been detected is transmitted by direct message such as e-mail or SNS. In the second embodiment, a warning for notifying the user (guardian) that a sign of bullying has been detected by the warning output unit 38 is output to the screen as character information, or is output to the speaker by voice. To do.

  In the second pattern shown in the flowchart of FIG. 7, in S05 of the flowchart of FIG. 5, the SNS server 20 is requested to send a friend list of the logged-in user (child). Sending text data is not requested. In the user (child) terminal 10 after transmitting the request, only the friend list is acquired (S12).

  The method for calculating the number of friends in the number-of-friends calculation unit 14 is the same as the first pattern described above, and the calculation of the increase / decrease in the number of friends and the update processing of the latest number of friends stored in the friend information storage unit 15 are performed. (S13). It is determined whether the calculated increase / decrease in the number of friends matches a predetermined condition for determining that the number of friends is rapidly decreasing (S14).

  If the number of friends does not meet the condition judged to be rapidly decreasing, the processing is terminated as it is that there is no sign of bullying, but if the condition is judged to be suddenly reduced, The SNS server 20 is requested to transmit text data such as a comment written in the account of the user (child) or a message transmitted / received by the user (child), and the information is acquired (S15).

  The text data analysis method (S16) in the text data analysis unit 16, the confirmation (S17) that there is no writing indicating bullying, and the subsequent processing (S18) are the same as in the first pattern. The pattern 2 has an efficient configuration that enables reduction of the amount of data acquired from the SNS server 20 by performing a float to acquire text data only when the number of friends is rapidly decreasing.

  In the above explanation, in both the first pattern and the second pattern, it is determined that there is a sign of bullying when the number of friends suddenly decreases and there is a sign of bullying in the text data. Is assumed. In order to increase the accuracy of the determination, it is preferable to use the analysis of the text data in this way, but in order to reduce the processing burden on the terminal, a simple configuration in which the determination is made only by increasing or decreasing the number of friends may be adopted. Is possible.
