Abstract

A method by which a user can use a function of a subscriber identity module (SIM) without directly inputting a personal identification number (PIN). The user can directly input the user'"'"'s personal information corresponding to a predetermined security question for user authentication of the mobile communication terminal. The security question can be configured according to the user'"'"'s preference. The user'"'"'s personal information corresponding to the security question is a short answer that the user can easily remember, so that even when the user forgets the PIN or does not have a personal unblocking key (PUK), the PIN is provided immediately after the identity of the user is verified through an input of the user'"'"'s personal information corresponding to the security question rather than a PUK input.

Claims

1. A method for managing personal identification information of a subscriber identity module (SIM) card in a mobile communication terminal, comprising:

displaying a security question for user authentication selected from the SIM card by a user;

receiving an input of the user'"'"'s personal information corresponding to the security question;

determining if the input personal information matches personal information stored in the SIM card; and

performing a normal operating mode if the input personal information matches the stored personal information.

2. The method according to claim 1, further comprising:

selecting, by the user, the security question for user authentication;

receiving an input of the user'"'"'s personal information serving as an answer to the security question when the security question has been selected; and

mapping the input personal information to the security question and storing a result of the mapping.

3. The method according to claim 1, further comprising:

receiving the user'"'"'s personal information input from the user when the security question requiring the input of the user'"'"'s personal information is displayed;

comparing the input personal information with the personal information stored in the SIM card;

displaying a personal identification number (PIN) stored in the SIM card when the input personal information matches the stored personal information; and

performing the normal operating mode when an input PIN is equal to the PIN stored in the SIM card.

4. The method according to claim 3, further comprising:

receiving a re-input PIN within a predetermined number of times when the input PIN is different from the PIN stored in the SIM card.

5. The method according to claim 3, further comprising:

notifying the user that a function of the SIM card is unavailable when the input PIN is different from the PIN stored in the SIM card.

6. The method according to claim 1, wherein the security question stored in the SIM card and the user'"'"'s personal information corresponding thereto can be edited and stored by the user.

7. The method according to claim 6, wherein the security question and the user'"'"'s personal information corresponding thereto are stored along with the PIN when an initial registration procedure for the SIM card is performed.

8. The method according to claim 1, wherein the security question is automatically displayed on a screen when the mobile communication terminal is powered on.

9. The method according to claim 1, wherein the security question is displayed according to the user'"'"'s selection of displaying the security question when the mobile communication terminal is powered on.
