Abstract
Disclosed herein are a server, system, method, and recording medium for searching for missing children, using mobile crowdsourcing. According to an embodiment, a server for searching for missing children, using mobile crowdsourcing, comprises a communication unit and a control unit. The communication unit receives a missing-child incident signal from a guardian terminal (held by a parent or guardian) and receives a first location information as to movements of a missing child from a child terminal (carried by the missing child) and sends the first location information received to at least one assistance terminal and receives landmark information from the assistance terminal(s) when a (degree of) similarity between the first location information sent to the assistance terminal(s) and a second location information detected by the assistance terminal(s) is higher than a preset value. The control unit generates a movement or moving path of the missing child, using the landmark information received.
