Server, system, method and recording medium for searching for missing children using mobile crowdsourcing
First Claim
1. A server for searching for missing children using mobile crowdsourcing comprising:
- a communication unit forreceiving a missing-child incident signal from a guardian terminal,receiving a first location information as to movements of a missing child from a child terminal on the missing child,transmitting the first location information received to at least one assistance terminal, andreceiving landmark information from the at least one assistance terminal when a degree of similarity between the first location information transmitted to the at least one assistance terminal and a second location information detected by, and stored in, the at least one assistance terminal is higher than a preset value,wherein the similarity is calculated and evaluated based on a given signal strength among a plurality of wireless signals and information there from acquired at a given point or location by the at least one assistance terminal;
anda control unit for generating a moving path of the missing child, using the landmark information received;
wherein the second location information is location information as to where a user of the at least one assistance terminal was at a given time point before and where the user is after receiving the missing-child incident signal.

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.

18. A method for searching for missing children using mobile crowdsourcing, comprising:
-
a child terminal transmitting a first location information based on wireless signal detected to a guardian terminal; the guardian terminal transmitting the first location information and missing child incident signal to a server; the server transmitting the first location information received from the child terminal or the guardian terminal to an assistance terminal; the assistance terminal first calculating and evaluating a similarity between the first location information transmitted and a second location information detected by the assistance terminal and then, only when the similarity evaluated is higher than a preset value, outputting an assistance request message to an interface unit of the assistance terminal; the assistance terminal transmitting landmark information inputted by an assistance terminal user, who recognizes the assistance request message, to the server; and the server generating a moving path of the missing child using the landmark information transmitted. - View Dependent Claims (19, 20)
