Abstract

A method and a mobile terminal where reproduction of a security barcode in a mobile terminal including a special function is prevented. When a security function is executed, a security barcode corresponding to security barcode generation information is generated and the special function is controlled. When the security function is released, the generated security barcode is removed and the control of the special function is released. When the special function is executed, execution information of the special function is stored. When the security function is executed again, the execution information of the special function is added to the security barcode generation information so as to generate new security barcode generation information. A security barcode corresponding to the new security barcode generation information is generated, and the generated security barcode is displayed.

Claims

1. A method for preventing a security barcode from being reproduced in a mobile terminal including a special function, the method comprising the steps of:

when a first security function is executed, generating a first security barcode corresponding to first security barcode generation information and controlling the special function;

when the first security function is released, removing the first security barcode and releasing the control of the special function;

when the special function is executed, storing execution information of the special function; and

when a second security function is executed, adding the execution information of the special function to the first security barcode generation information to generate a second security barcode generation information, generating a second security barcode corresponding to the second security barcode generation information, and displaying the second security barcode.

2. The method as claimed in claim 1, further comprising a step of receiving the security barcode generation information through at least one of local area network communication and a connector.

3. The method as claimed in claim 1, further comprising a step of storing at least one of the first and second security barcode generation information.

4. The method as claimed in claim 1, wherein at least one of the first and second security barcode generation information comprises at least one of personal information of a user and encrypted Electronic Serial Number (ESN) information.

5. The method as claimed in claim 1, wherein the special function comprises at least one of a camera function, an MP3 function, a mobile storage medium function, and a data transmission function.

6. The method as claimed in claim 1, wherein the execution information of the special function comprises at least one of type information of the executed special function and time information regarding the execution of the special function.

7. A method for preventing a security barcode from being reproduced in a mobile terminal including a special function, the method comprising the steps of:

when a security function is executed, generating a first security barcode corresponding to security barcode generation information and controlling the special function;

when signals are generated, storing time information regarding the generation of the signals; and

adding the time information to the security barcode generation information, and generating and displaying a second security barcode corresponding to the security barcode generation information comprising the time information added thereto.

8. The method as claimed in claim 7, further comprising a step of receiving the security barcode generation information through at least one of a connector and local area network communication.

9. The method as claimed in claim 7, wherein the security barcode generation information comprised at least one of personal information of a user and encrypted Electronic Serial Number (ESN) information.

10. The method as claimed in claim 7, wherein the special function comprised at least one of a camera function, an MP3 function, a mobile storage medium function, and a data transmission function.

11. The method as claimed in claim 7, wherein the signals are generated when a folder of the mobile terminal is opened or closed, or when a keypad is operated.

12. The method as claimed in claim 7, wherein, when at least one of the first and second security barcodes are read, both the first and second security barcodes are determined as the same security barcodes, when time information is subtracted from the second security barcode.

13. A mobile terminal configured to perform a special function, the mobile terminal comprising:

an interface for commanding execution of a special function;

a display unit;

memory comprising at least one of a program memory for storing programs for generating a security barcode, and for controlling the special function, and a data memory for storing a security barcode generation information;

and a controller;

when a first security function is executed, the controller controls generation of a first security barcode corresponding to a first security barcode generation information and controls the special function;

when the first security function is released, the controller removes the first security barcode and releasing the control of the special function;

when the special function is executed, execution information of the special function is stored in the data memory; and

when a second security function is executed, the execution information of the special function is added to the first security barcode generation information to generate a second security barcode generation information, a second security barcode corresponding to the second security barcode generation information is generated, and the second security barcode is displayed on the display unit.

14. The mobile terminal as claimed in claim 13, wherein the interface comprises a keypad.

15. The mobile terminal as claimed in claim 13, further comprising at least one of a connector and local area network communication configured to receive the security barcode generation information.

16. The mobile terminal as claimed in claim 13, wherein the data memory is configured to store at least one of the first and second security barcode generation information.

17. The mobile terminal as claimed in claim 13, wherein at least one of the first and second security barcode generation information comprises at least one of personal information of a user and encrypted Electronic Serial Number (ESN) information.

18. The mobile terminal as claimed in claim 13, wherein the special function comprises at least one of a camera function, an MP3 function, a mobile storage medium function, and a data transmission function.

19. The mobile terminal as claimed in claim 13, wherein the execution information of the special function comprises at least one of type information of the executed special function and time information regarding the execution of the special function.
