Abstract

Various embodiments of a searching method for a missing child using a two-dimensional bar code are disclosed. In one exemplary embodiment, the method may include photographing a two-dimensional bar code possessed by a missing child through a missing child prevention program and receiving current position information through a GPS module and stores the received position information. The method may also include transmitting the two-dimensional bar code and the stored position information to a two-dimensional bar-code server, receiving child and guardian information of the missing chilled from the two-dimensional bar code server, and displaying the received child and guardian information. The method may also include connecting a call to the missing child'"'"'s guardian by inputting a call connection key.

Claims

1. A method of searching a missing child using a two-dimensional bar code, which is performed by a portable terminal, the method comprising:

photographing a two-dimensional bar code possessed by a missing child through a missing child prevention program;

receiving current position information through a global positioning system (GPS) module and storing the received position information when the missing child prevention program is executed;

transmitting the photographed two-dimensional bar code and the stored position information to a two-dimensional bar-code server;

receiving child and guardian information of the missing child from the two-dimensional bar-code server and displaying the received child and guardian information; and

connecting a call to the missing child'"'"'s guardian by inputting a call connection key.

2. The method of claim 1, further comprising, prior to photographing the two-dimensional bar code:

receiving child and guardian information through the missing child prevention program;

transmitting the child and guardian information to the two-dimensional bar-code server and requesting the two-dimensional bar-code server to generate the two-dimensional bar code; and

receiving the two-dimensional bar code corresponding to the child and guardian information from the two-dimensional bar-code server.

3. A method of searching for a missing child using a two-dimensional bar code, which is performed by a two-dimensional bar-code server, the method comprising:

receiving, from a missing child finder client, a two-dimensional bar code possessed by a missing child and photographed by the missing child finder client and position information of the missing child finder client;

searching for child and guardian information corresponding to the two-dimensional bar code;

transmitting the searched child and guardian information to the missing child finder client;

transmitting the information and position information of the missing child finder client to a missing child'"'"'s guardian using the searched guardian information; and

generating missing child occurrence information containing the child information and the position information of the missing child finder client and transmitting the generated missing child occurrence information to members that install a missing child prevention program.

4. The method of claim 3, further comprising, prior to receiving the two-dimensional bar code from the missing child finder client:

receiving child and guardian information from a guardian client; and

generating a two-dimensional bar code corresponding to the received child and guardian information and transmitting the generated two-dimensional bar code to the guardian client.

5. The method of claim 3, wherein the guardian information is at least one portable terminal number or telephone number, and the guardian information receiving the information and position information of the missing child finder client is a portable terminal number.

6. A method of searching for a missing child using a two-dimensional bar code, comprising:

photographing, by a missing child finder client, a two-dimensional bar code possessed by a missing child through a missing child prevention program, and receiving current position information through a GPS module and storing the received position information;

transmitting the photographed two-dimensional bar code and the stored position information to a two-dimensional bar-code server;

searching for, by the two-dimensional bar-code server, child and guardian information corresponding to the two-dimensional bar code received from the missing child finder client;

transmitting, by the two-dimensional bar-code server, the searched child and guardian information to the missing child finder client;

receiving, by the missing child finder client, the child and guardian information of the missing child from the two-dimensional bar-code server and displaying the received child and guardian information; and

connecting, by the missing child finder client, a call to a missing child'"'"'s guardian using the received guardian information.

7. The method of claim 6, wherein the guardian information is at least one of a portable terminal number and a telephone number.
