The text message may be provided in the form of, for example, a Short Message Service (SMS) and a Multimedia Messaging Service (MMS), and may be transmitted from a web server providing another mobile communication terminal or a text message service to the message receiving unit 100 Can be provided.

The message reading unit 200 receives the text message from the message receiving unit 100 and determines whether it is a general text message or a personal information deletion message. In addition, when the received message is a personal information deletion message, the message reading unit 200 instructs the data processing unit 400, which will be described later, to delete personal information. The message reading unit 200 searches a specific character string indicating the personal information deletion message from the contents of the text message and confirms that the character message is a personal information deletion message when the specific character string exists.

Meanwhile, the specific character string may be a value preset by a user of the mobile communication terminal, and the specific character string may be a combination of numbers, letters, and special symbols, for example. In addition, the user can set the specific character string to a different character string according to the type of personal information to be deleted. For example, the user can delete a specific character string for deleting a picture, deleting a moving picture, deleting a phone number, They can be set differently. In this case, the message reading unit 200 searches the text message for a specific character string set for the type of the personal information, confirms that the text message is a personal information deletion message, And can instruct the deletion of the corresponding personal information.

The validity review unit 300 determines whether the personal information deletion message determined by the message reading unit 200 is a valid validated message and provides the validity to the data processing unit 400. The personal information stored in the mobile communication terminal may be set to have a different security level according to the importance, and the validity review unit 300 may determine whether the personal information deletion message is valid according to the security level of the personal information.

For example, the information of the third grade can determine the validity of the deletion message by checking only the specific string, and the information of the second grade can determine the validity of the private information deletion message by checking the specific character string and the user's password of the mobile communication terminal can do. In addition, for example, the first rank information can determine the validity of the personal information deletion message by checking the specific character string, the user's password of the mobile communication terminal, and the telephone number of the sender of the text message. Accordingly, important personal information with a high security level can be erroneously erroneously erased, or a third party can more thoroughly prevent a specific character from being stolen.

The data processing unit 400 receives the personal information deletion command from the message reading unit 200 and deletes the personal information stored in the mobile communication terminal. When a specific character string for deleting personal information is set differently according to the type of personal information, the data processing unit 400 may selectively delete personal information corresponding to the specific character string. In addition, the data processing unit 400 may delete personal information only when the personal information deletion message is valid.
