In addition, the inclusion of a certain component means that the component may be further included, without excluding the other component, unless specifically stated otherwise.

In addition, the term 'module' refers to a unit for processing a specific function or operation, which may be implemented in hardware or software or a combination of hardware and software.

1 is a block diagram showing the overall configuration of a personal information protection and tracking system of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 1, the system of the present invention includes a server tracking client device 10 installed in a mobile terminal, and a server device 20 connected to the terminal tracking client device 10 through a communication network (wired or wireless). )

The terminal tracking client device 10 controls resources of the portable terminal such that any holder (for example, the acquirer) cannot use the portable terminal according to a remote command, and controls the current location of the portable terminal (for example, GPS). Coordinates or base station information) is detected and transmitted to the server apparatus 20 or a designated number. In addition, the personal information stored in the portable terminal is uploaded to the server device 20, the personal information is deleted from the portable terminal, or the uploaded personal information is downloaded from the server device 20 to the portable terminal.

To this end, the terminal tracking client device 10 includes a user interface (UI) module 11 and a remote command processing module 12.

The UI module 11 provides a user interface and changes the settings of the terminal tracking client device 10 according to the user's request, or receives a user's personal information upload / download command and receives the remote command processing module ( 12), and receives a UI request input from the remote command processing module 12 to perform a function of displaying on the screen of the portable terminal. The user interface of the UI module 11 may be in the form of a text-based menu.

The remote command processing module 12 receives a remote command transmitted from the server device 20, controls the portable terminal to prevent the holder from using the portable terminal according to the remote command, and displays current position information of the portable terminal. Is periodically transmitted to the server device 20 or a designated number, and the personal information of the mobile terminal is uploaded to the server device 20 or from the server device 20 according to the user setting transmitted from the UI module 11. Download personal information and store it in your mobile device. In addition, the remote command processing module 12 checks the validity of the USIM card and controls the portable terminal not to be used when the USIM card is not registered. Here, since the portable terminal must be turned off to replace the USIM card, the validity check of the USIM card is preferably executed every time the terminal tracking client device 10 is first executed.

The UI module 11 and the remote command processing module 12 may be implemented as a binary runtime environment for wireless (BREW) applet, and the remote command may be implemented in the form of a BREW message. In addition, since the terminal tracking client device 10 is once installed in the portable terminal, the terminal tracking client device 10 should not be deleted until the terminal tracking function is cancelled. Further, in order to make the holder unable to recognize the process of processing the remote command, it is preferable not to display the process of performing the remote command on the screen of the portable terminal. To do this, you can use the Background Applet, first introduced in BREW 2.0. In addition, in order to prevent any restriction in protecting the mobile terminal, the terminal tracking client device 10 is set to be available to all resources of the mobile terminal. The UI module 11 and the remote command processing module 12 communicate with each other through event delivery. The event to be used here must be defined with the same value in both the UI module 11 and the remote command processing module 12. These defined events can be delivered using ISHELL_PostEvent and ISHELL_SendEvent.

In addition, the terminal tracking client device 10 is preferably driven automatically when the power of the portable terminal is increased. If the terminal does not run automatically when it is large, privacy protection may be impossible and tracking of the lost terminal may be difficult. As an automatic execution method, for example, by registering an applet in a BREW setting item called CFGI_AUTOSTART, the applets registered in the item operate immediately after the initialization of the BREW is completed. Alternatively, the alarm function can be used to cause the terminal tracking client device 10 to operate within a predetermined time (eg, 1 minute).

The operation mode of the terminal tracking client apparatus 10 described above can be largely divided into a normal mode, a lost mode, and a locked mode.

The general mode refers to an operation state in which personal information and functions in the portable terminal can be used smoothly. In the normal mode, it is possible to set the functions of the terminal tracking client device 10 through the UI module 11, and the functions set in the UI module 11 also operate in the normal mode.

The locked mode is an operation mode in which a wrong number of times or a non-registered USIM card is confirmed when a password is input for authentication in a normal mode. In the locked mode, a message indicating that the portable terminal is locked is displayed, and the portable terminal cannot be used. At this time, it is desirable to be able to receive calls and texts. The locked mode can be released by inputting the password registered in the portable terminal. At this time, the location tracking function of the portable terminal does not operate.

The lost mode is an operation mode executed through a remote command from the server device 20, and a message indicating a lost portable terminal appears on the screen of the portable terminal, and the portable terminal cannot be used. Is done. At this time, telephone reception is possible. In addition, in the lost mode, the general text message received by the mobile terminal may be transmitted to another designated number. The lost mode may be released only by a remote command sent from the server device 20.

Preventing the mobile terminal from being used in the terminal tracking client device 10 may be implemented by blocking key input in the mobile terminal. That is, the terminal tracking client device 10 intercepts the key input signal so that the portable terminal does not recognize the key input.

The detailed configuration and operation of the terminal tracking client device 10 will be better understood from the following description.

Next, the server device 20 is a means for controlling the terminal tracking client device 10 by transmitting the remote command to the terminal tracking client device 10, and may transmit the remote command according to a user's request. . In addition, the server device 20 manages personal information uploaded from or downloaded to the mobile terminal. To this end, the server device 20 may be implemented as a web server, and more specifically, a web interface unit 21 for providing a remote control menu for remotely controlling a mobile terminal to a user, and the web interface unit. Remote command transmission unit 22 for generating a remote command in accordance with the user's request through the (21) to the terminal tracking client device 10, and the terminal in accordance with the user's request via the web interface unit 21 Upload and download processing unit 23 for uploading personal information of the mobile terminal or downloading personal information of the mobile terminal through the tracking client device 10, and the user's request and upload and download through the web interface unit 21 And a storage unit 24 for storing personal information of the portable terminal.

In order to use the remote control menu provided by the web interface unit 21 of the server device 20, it is preferable to allow the user to apply for service opening after joining the membership. The terminal authentication at the time of service opening may be performed by sending an One Time Password (OTP) to the terminal and inputting it into a web page to confirm. In addition, the server device 20 receives a password set in the terminal tracking client device 10 from a user through a web page. In this case, the server device 20 carries the password in order to confirm whether the password is the same as the password stored in the mobile terminal. Send a BREW SMS to the terminal, the terminal tracking client device 10 checks it and sends a success message in HTTP if the passwords match, and sends a failure message if the passwords do not match or there is no service opening history.

The remote control menu provided to the user by the server device 20 may include 'activating the concealing menu', 'lost setting', 'personal information backup', 'deleting personal information', 'receiving message', and 'alarm operation'. Contains'

'Activate hidden menu' menu is a menu for activating a hidden terminal tracking menu to be displayed in the content list.

The 'Lost Setting' menu is a menu for executing the privacy and location tracking of the portable terminal when the user loses the portable terminal. When the user selects the 'Lost Setting' menu, the terminal tracking client device ( 10) a remote command is sent to command the setting to the lost mode.

The 'personal information backup' menu means to transmit the personal information (eg, a phone book, a call log, etc.) designated by the user to the terminal tracking client device 10 to the server device 20 for backup. do. When the 'personal information backup' is selected in the remote control menu, the corresponding remote command is transmitted to the terminal tracking client device 10, and the terminal tracking client device 10 transmits personal information in the background after password authentication. At this time, if the transmission of the personal information is interrupted or fails, it can be restarted automatically, and if more than a predetermined number of consecutive failures stop the transmission and send the backup failure message to the server device (20).

The 'receive message switch' menu allows the terminal tracking client device 10 to send all messages received to the portable terminal to a specified number. The designated number may be a spare terminal number set through the user interface of the terminal tracking client device 10 or a telephone number attached to the remote command. The priority here is preferably the higher the number attached to the remote command.

The 'alarm operation' menu is to set an alarm sound immediately in the portable terminal, and can be used to notify people around that the lost mobile phone. Preferably, the alarm operation is selectable only when a loss setting is selected.

In the above description, the remote command transmitted from the server device 20 to the terminal tracking client device 10 may be in the form of "command code + password of a mobile terminal".

2 is a block diagram showing a detailed structure of the UI module 11 included in the terminal tracking client device 10. As shown in FIG.

Referring to FIG. 2, the UI module 11 is a state machine-based applet, the UI portion 111 showing a text-based menu to a user, and a handler for processing an input received through the menu. and a handler portion 112. The state information that the UI module 11 depends on includes an init function 112a for initializing a user interface for a state such as configuring an initializing screen of a menu to be shown to a user, and processing an event generated from the state. It consists of an event handler 112b.

When all the state information is initialized by the UI module 11, it is configured in the state control function information 112c, and then placed in the state stack 112d for current state management. Record when the state is changed by an applet internal operation. As a result, when a new state enters the state stack 112d, the state handle manager 112e calls the initialization function 112a to initialize a state and call a function for handling an event.

The initialization function 112a and the event handler 112b for the state are obtained with reference to the state control information 112c. When the remote command processing module 12 sends an event, the state manager 112e receives and processes the event.

The UI module 11 configures a user interface in the form of a text-based menu, and each menu corresponds one to one in one state. Whenever the user selects a menu, the state of each menu is stored in the state stack 112d, and when an event occurs, the event is first delivered to the state at the top of the state stack 112d, and the event is not processed. If not, it forwards the event to the state below it for processing.

The event handler receives and processes all events first. According to the above function, the state manager 112e first checks the state stored in the stack, and then processes the event by finding the event processing function of the state in the state control information. do. Data set in each menu of the UI module 11 is stored in a config.dat file using a serialization technique. When a user changes a setting, the change is temporarily stored only in memory and is reflected when the mobile device is turned off and on.

3 is a block diagram showing the detailed structure of the remote command processing module 12 in the terminal tracking client device 10. As shown in FIG.

As described above, the remote command processing module 12 is a background applet that automatically calls a processing function and sends the processing result when receiving a remote command or an event sent from the UI module 11. Unlike (11), it is composed of a structure that processes each time an external event is received without depending on the state information.

Referring to FIG. 3, the remote command processing module 12 may include a UI agent 121 for processing an event coming from the UI module 11 and a remote command handler 122 for processing a remote command coming from the server device 20. And a data transmission manager 123 for uploading personal information from the mobile terminal to the server device 20 or downloading from the server device 20 to the mobile terminal according to a request of the UI agent 121 and the remote command handler 122. ).

The remote command handler 122 analyzes the remote command transmitted from the server device 20, requests the UI agent 121 to update the UI when a UI update is required, and transmits the data when transmitting personal information. A request is made to the manager 123. In addition, a command for deleting a setting or deleting personal information or a received message switching command due to a lost terminal is directly processed.

The UI agent 121 communicates with the UI module 11 and does not perform a determination or data processing operation, and simply receives a message received from the UI module 11 from the remote command handler 122 or the data transmission manager 123. ) And the processing result thereof to the UI module 11 as an event.

The data transmission manager 123 uploads and downloads data by performing HTTP communication with the server device 20. The data transmission manager 123 operates asynchronously in the terminal tracking client device 10, and processes only a certain amount of data in a given time through a timer and repeats it again after a predetermined period to complete the entire work. This is to prevent the overall UI of the user and to upload / download personal information without the user's knowledge in the lost mode.

In addition, the data transmission manager 123 may perform upload / download according to a message transmitted from the UI agent 121. In this case, the data transmission manager 123 may update the screen when receiving a callback function and transmitting a predetermined amount. In this case, it is desirable to shorten the repetition period to complete upload / download as soon as possible.

The terminal tracking client apparatus 10 described above should always operate in the foreground or background in the portable terminal in order to prevent the learner from illegally using personal information or the terminal when lost.

The terminal tracking client device 10 may be installed in the portable terminal in various ways according to the shape of the applet. For example, there is a method of directly downloading and installing wirelessly, installing in a mobile terminal in advance of the terminal release, or compiling like a phone source and installing in a terminal binary form in a ROM. Since these methods have their advantages and disadvantages, the installation method can be appropriately selected as necessary.

When the menu is selected, the user can select the manual method of uploading the selected information to the server immediately.

In the case of automatic upload, the upload time (or cycle) can be specified for each data type. When the upload time (cycle) is designated as described above, each time the corresponding time (cycle) is reached, the information upload event is transmitted to the remote command processing module 12 and the information is transmitted by the data transmission module 123 therein. The upload is executed.

Next, the 'information download' menu shown in FIG. 4A is a menu for downloading information uploaded to the server device 20 back to the mobile terminal. As shown in FIG. 4D, a type of data to be downloaded can be selected. Including the sub-menu, the user selects and downloads the desired information.

In addition, the 'setting' menu is for specifying various setting information of the terminal tracking client device 10, and as a submenu thereof, as shown in FIG. 4E, 'password setting', 'alarm setting', and 'information protection range setting'. 'Set terminal number setting', presentation information setting ', and' registration terminal number setting 'menu.

The 'password setting' menu is to set a password for user authentication upon activation of the concealed menu and release of the lost mode. The 'Alarm Settings' menu is intended to warn the user of unauthorized use, for example, if an unregistered USIM card is confirmed, or if password authentication has failed more than a set number of times, as an unauthorized user's unauthorized use or access. Generate a beep.

When the unregistered USIM card is confirmed or the password authentication fails more than a predetermined number of times, the 'information protection range setting' menu automatically uploads the personal information of the set range to the server device 20 and then deletes the personal information. To prevent the leakage of information. In the locked mode, the personal information may not be deleted because it may be caused by the original owner's mistake.

The 'preliminary terminal number setting', when operating in the lost mode transfers the message received by switching the reception of the message, or when an illegal use (for example, confirmation of the unregistered USIM card) is notified about this message Set the destination to send. The preliminary terminal number may be a telephone number of an acquaintance.
