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.
