PURPOSE: A system preventing dotard disappearance and a missing child and a method thereof are provided to find locations of a dotard or a child having a Wi-Fi transceiver, thereby preventing a disappearance accident. CONSTITUTION: A dotard and missing child prevention system(100) includes a Wi-Fi transceiver(110), a Wi-Fi sharing router(120) and a service server(130). A dotard or a child has the Wi-Fi transceiver which searches the Wi-Fi sharing router. When the Wi-Fi sharing router is searched, the Wi-Fi transceiver transmits a MAC address to the detected Wi-Fi sharing router. The service server receives a unique number and the MAC address of the Wi-Fi transceiver and finds personal information for the dotard or the child having the Wi-Fi transceiver.
