According to one embodiment of the present invention, a guardian can predict or recognize, in advance, a dangerous situation (for example, school violence) of a ward by monitoring a danger-message received by the ward. Particularly, according to one embodiment of the present invention, a guardian can know, in advance, information on a perpetrator and wrongdoing information of the perpetrator by providing the name or contact information of the perpetrator and/or the names or contact information of other wards related to the perpetrator about whom a danger-message has been sent, wherein only a portion of the names or contact information can be shown to the guardian by considering the indiscreet exposure of personal information such as the names or contact information. In addition, according to one embodiment of the present invention, a danger-message received by a ward can be transmitted to a school terminal of the ward such that a school part can know, in advance, of a dangerous situation or information on a perpetrator, and if threatening words included in the danger-message seem like a joke, the danger-message can be filtered out and provided to the guardian. |
