The present invention relates to a method for deleting personal information stored in a mobile communication terminal, and more particularly, a terminal using a wireless internet platform according to a short message inserted with a request of a subscriber who has lost a mobile communication terminal. It relates to how to delete the personal information stored in.

As mobile communication terminals become basic necessities of life, users store personal information such as personal phone numbers and memos in mobile communication terminals. Such personal information may include incoming / outgoing short message history, phone book, personal schedule history, personal memo, music file, video file and photo file.

Meanwhile, there is a possibility of loss due to the portability of the mobile communication terminal. If the user loses the mobile communication terminal, personal information stored in the terminal may be leaked to others. In particular, when a mobile communication terminal in which important personal information such as a bank account number, a social security number, or an account password is lost, such personal information is leaked to a fraudulent user, causing financial and mental damage to the user.

Conventionally, when a mobile communication terminal is lost, a subscriber may call the customer service center of the mobile communication service company or access a customer service web page using a computer to report the loss of the terminal, check the current location of the terminal, and request a terminal prohibition service.

The subscriber who has lost the mobile communication terminal may call the customer service center of the mobile communication service company or access the customer center webpage using a computer to request the loss of the terminal and request the deletion of personal information stored in the terminal. Hereinafter, the present invention will be described with an example that a subscriber requests a terminal loss report and personal information stored in the terminal on a customer center web page by using a computer.

First, the subscriber accesses the customer center web page using a computer, and reports the loss of the mobile communication terminal and a request for deleting personal information (1). At this time, in the customer center, the item of the mobile communication terminal lost from the subscriber on the web page, the personal information stored in the memory of the lost mobile communication terminal (eg, a text box or a phone book) and the subscriber Input the destination information to be notified of the result of deleting personal information.

When the subscriber's mobile communication terminal loss report and personal information deletion request are received as described above, the terminal loss processing center associated with the customer center refers to the short message service center (SMSC), hereinafter referred to as "SMSC". Request a transmission of an SMS including a command code to delete personal information stored in the lost mobile communication terminal (2). In addition to the command code, the SMS includes the phone number of the lost mobile communication terminal and the phone number of the customer center. The destination of the SMS becomes a lost mobile communication terminal, and the telephone number of the terminal loss processing center side becomes a sender.

Accordingly, when the SMS including the personal information deletion command code is received from the SMSC by the lost mobile communication terminal, the mobile communication terminal analyzes the SMS and performs a personal information deletion command using a wireless Internet platform (3). . Here, the process of the mobile terminal analyzing the SMS and performing the personal information deletion command using the wireless Internet platform will be described in detail with reference to FIG. 4.

Thereafter, the mobile communication terminal transmits a personal information deletion completion message to the terminal loss processing center through SMSC when the personal information deletion command is completed (4). At this time, the personal information deletion complete message is sent to the SMSC using the mobile phone terminal number as the sender and the phone number of the terminal loss processing center as a destination, and the SMSC checks the destination phone number and sends it to the terminal lost processing center. Deliver information deletion complete message.

On the other hand, if the terminal loss processing center does not receive the SMS [personal information deletion complete message] in response to the SMS [personal information deletion command message] sent to the lost mobile communication terminal through the SMSC from the mobile terminal within the preset expiration period; The SMS including the personal information delete command code is retransmitted to the mobile terminal through the SMSC.

Accordingly, the terminal loss processing center side performs a call prohibition process of the lost mobile communication terminal with reference to the source telephone number of the received personal information deletion completion message (5).

Then, the terminal loss processing center side deletes the personal information to the mobile communication terminal user by referring to the destination information to be notified of the result of the personal information deletion processing that the mobile communication terminal user has inputted when reporting the loss report and the personal information deletion on the web page. Inform that completion is completed (6).

In the above process, when the terminal loss processing center receives a terminal loss report and personal information deletion request from the subscriber, and sends a personal information deletion command message to the mobile communication terminal and performs the transmission prohibition process of the lost mobile communication terminal, The lost mobile communication terminal cannot send a personal information deletion complete message according to the completion of the personal information deletion command. Therefore, it is preferable that the terminal loss processing center side performs a transmission prohibition process after the personal information deletion completion message arrives from the lost mobile communication terminal.

The structure of the SMS including the command code in the above process will be described in more detail with reference to FIGS. 2A to 2B.

In order to describe the preferred embodiment to which the present invention is applied, the wireless Internet platform will be described using the Wi-Fi platform commonly used by the mobile communication service providers described above as an example, and the SMS message standard to be transmitted to the lost mobile communication terminal from the customer center side will be described. For example, the WIPI Common SMS Push message standard, which is a standard of SMS Push messages commonly used in the Wi-Fi platform, will be described. Here, the WIPI Common SMS Push message means that a specific TID (Teleservice ID: Service Identifier) inserted into the SMS is recognized by the Wi-Fi platform's Daemon application even when the mobile terminal in the standby mode is executed. This is the message to do.

Figure 2a is an explanatory diagram of an embodiment of a Wi-Fi platform standard SMS Push message used in the present invention.

The data in the WIPI Common SMS Push message mentioned earlier is a "User Interface" code that indicates what the user will be using for short messages, and a "Message" code that displays what commands the SMS performs, "UI" It consists of "Command-Defined-Data" code, which contains "Command" code that indicates which command to execute according to code, and specific execution command according to "Command" code.

2B is an explanatory diagram of an embodiment of a Wi-Fi platform standard SMS Push message containing a personal information deletion command according to the present invention.

The WIPI Common SMS Push message for deleting personal information stored in the terminal using the Wi-Fi platform includes a specific TID (Teleservice ID: Service Identifier) for content download or data transfer using the Wi-Fi platform. The "UI" code corresponding to the details of this TID (Service Identifier) has a value of "4" [Service Identifier], which is a value to transmit data using the Wi-Fi platform. The "Message" code has the same text as "Warning! Delete Personal Information" to display that the personal information is deleted. The "Command" code has a value of "T" that tells the agent to execute the next command. The "Command-Defined-Data" code, which is the data to be passed to the agent on the Wi-Fi platform, is the "Program-Defined" code that contains the "Program-name" code [application identifier] that invokes the application and the detailed commands that the called agent specifically executes. -Data "code [personal information to be deleted].

[Table 1] below is an example of details of the "Program-Defined-Data" code described above.

In order to confirm the purpose of the push message, a specific TID (Teleservice ID) in the short message is checked (110). In FIG. 4, the SMS Push message is a message having the message standard of FIG. 2B which commands deletion of personal information.

If the purpose of the SMS Push message is to deliver data to the WiPie platform 12 as a result of confirming the specific TID (Teleservice ID: Service Identifier), the SMS Push Engine 14 sends the WiPi platform 12 to the WiPi platform 12. Deliver the SMS Push message (120). For example, in a general WIPI Common SMS Push message, if the TID (Teleservice ID: Service Identifier) has a value of "63005", it is a message for the purpose of downloading content and delivering data to the Wi-Fi platform 12. Referring to the message specification of FIG. 2B described above, a value of "4" in the "UI" code portion of the SMS Push message having the TID means data transfer.

Then, the Wi-Fi platform 12 checks the "Message" code of the received SMS Push message data, displays the corresponding character, and checks the agent name to be activated by referring to the "Program-name" code (130). As shown in FIG. 2B, the SMS Push message is a personal information deletion command message stored in a memory of a lost mobile communication terminal. Therefore, the Wi-Fi platform 120 checks the value of "Erase Agent" which means the personal information deletion agent in the "Program-name" code.

Accordingly, the WiPi platform 12 activates the Erase Agent 13, which is the personal information deleting agent, and transmits the SMS Push message to the Erase Agent 13 (140). Here, the Erase Agent 13 is activated (executed) by the application control of the Wi-Fi platform 12, and only an authorized authority or an application registered in advance so that the state activated by the unauthorized user is not released. It is desirable to be able to manipulate run / end. For example, this is to prevent a fraudulent user from randomly terminating a program by recognizing that the erase agent 13 is executed on the mobile communication terminal.

Accordingly, the Erase Agent 13 checks the content of the "Program-Defined-Data" code among the received SMS Push data (150). In FIG. 4, the contents of the command of the "Program-Defined-Data" code are "EraseAllData" which instructs to delete all personal information of the lost mobile communication terminal in the example shown in Table 1 above. If the subscriber wants to "delete the text box" instead of all the personal information, the content of the "Program-Defined-Data" code will be "EraseSMS".

Accordingly, according to the "EraseAllData" command, the Erase Agent 13 requests the Wi-Fi platform 12 to delete all personal information stored on the memory of the lost mobile communication terminal (160).

Then, the WiPy platform 12 requests the deletion of all personal information stored in the memory of the handset hardware to the handset basic software through the HAL application program interface (170).

Accordingly, all personal information stored in the memory of the handset hardware is deleted at the request of the handset basic software (180). Here, the process of deleting personal information on the handset hardware is the same as the known file deletion, and a detailed description thereof will be omitted.

Then, Handset Basic Software notifies the WiPie platform 12 that all personal information stored on the lost mobile communication terminal's memory has been deleted (190).

Accordingly, the WiPie platform 12 transmits the notification of deleting the personal information to the Erase Agent 13 (200).

Receiving the above personal information deletion completion (Erase Agent) 13 generates a personal information deletion completion message to notify the customer center (210), the personal information deletion completion message to the terminal lost processing center in the customer center Request 220 to send an SMS push engine (14) to transmit.
