Abstract

In a method for storing data in a memory card mounted in a mobile terminal, determining if the memory card is mounted in the mobile terminal. If the memory card is mounted in the mobile terminal, sensing data selected by a user to be stored in the memory card. If the selected data is determined to be downloadable chargeable content, unique information of the mobile terminal is included and encrypted in the chargeable content, and stored in the memory card. However, if it is determined that the selected data is general data. Then, it is determined if the general data must be encrypted. If the general data must be encrypted, the unique information of the mobile terminal is included in the general data, and the general data including the unique information of the mobile terminal is stored in the memory card.

Claims

1. A method for storing data in a memory card mounted in a mobile terminal, comprising:

determining if the memory card is mounted in the mobile terminal, and sensing data, selected by a user, to be stored in the memory card from among data stored in the mobile terminal if the memory card is mounted in the mobile terminal;

determining if the selected data is downloaded chargeable content, and including and encrypting unique information regarding the mobile terminal in the chargeable content to store a result of the encryption in the memory card if the selected data is the chargeable content; and

determining that the selected data is general data if the selected data is not chargeable data, determining if the general data must be encrypted, and including the unique information of the mobile terminal in the general data to store the general data including the unique information of the mobile terminal in the memory card if the general data must be encrypted.

2. The method of claim 1, wherein the unique information of the mobile terminal is a Mobile Identification Number (MIN) or Electronic Serial Number (ESN).

3. A method for reproducing data of a memory card mounted in a mobile terminal, comprising:

determining if the memory card is mounted in the mobile terminal, and reading data of the memory card if the memory card is mounted in the mobile terminal;

determining if the data read from the memory card is encrypted;

if the read data is encrypted, determining if encryption information included in the read data is the same as unique information of the mobile terminal, and reproducing the read data if the encryption information is the same as the unique information of the mobile terminal; and

if the encryption information is different from the unique information of the mobile terminal, preventing the read data from being reproduced.

4. The method of claim 3, wherein the unique information of the mobile terminal is a Mobile Identification Number (MIN) or Electronic Serial Number (ESN).

5. The method of claim 3, wherein the encryption information is a Mobile Identification Number (MIN) or Electronic Serial Number (ESN) of the mobile terminal.

6. The method of claim 3, further comprising:

when the read data is not reproduced, providing a notification by means of a guide text message or guide voice message indicating that the encryption information is different from the unique information of the mobile terminal.

7. A method for storing data in a mobile terminal, comprising:

determining if a memory card is mounted in the mobile terminal;

if the memory card is mounted in the mobile terminal, determining if data stored in the mobile terminal is transferred to the memory card;

if the data stored in the mobile terminal is transferred to the memory card, storing the data and encryption information together according to an encryption selection of a user; and

if the data stored in the mobile terminal is not transferred to the memory card, determining if data stored in the memory card is transferred to the mobile terminal, and storing the data in the mobile terminal according to the presence of encryption if the data stored in the memory card is transferred to the mobile terminal.

8. A mobile terminal apparatus comprising:

a memory card;

a controller adapted to perform the steps of;

determining if the memory card is mounted in the mobile terminal, and sensing data, selected by a user, to be stored in the memory card from among data stored in the mobile terminal if the memory card is mounted in the mobile terminal;

determining if the selected data is downloaded chargeable content, and including and encrypting unique information regarding the mobile terminal in the chargeable content to store a result of the encryption in the memory card if the selected data is the chargeable content; and

determining that the selected data is general data if the selected data is not chargeable data, determining if the general data must be encrypted, and including the unique information of the mobile terminal in the general data to store the general data including the unique information of the mobile terminal in the memory card if the general data must be encrypted.

9. The apparatus of claim 8, wherein the unique information of the mobile terminal is a Mobile Identification Number (MIN) or Electronic Serial Number (ESN).
