The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an embodiment of a portable terminal anti-theft device according to the present invention.

As shown in Figure 1, the anti-theft device of a portable terminal according to the present invention, the designated incoming telephone number (user's landline telephone number, etc.) and transmission history (for example, the terminal is stolen / lost according to the user's settings) ), Alarm details (e.g. warning message, siren, etc.), and camera image captured in alarm mode and terminal position coordinate values (e.g. 00 00 00 00 00 0 0 0 0 0 0 00) ) Is stored in the memory 13, the GPS receiver 19 for obtaining the position coordinate value of the terminal in the alarm mode under the control of the control unit 10, and the terminal in the alarm mode under the control of the control unit 10. According to the detection result of the vibration detection unit 11 or the opening and closing detection unit 12 and the vibration detection unit 11 or the opening and closing detection unit 12 for detecting an environment change by the vibration or opening and closing of the terminal, the environmental change of the terminal Control scene when (vibration, folder or flip open) A control unit 10 for outputting a signal, an alarm generation unit 16 for amplifying the alarm details according to a control signal, and outputting an audio signal, and driving the camera 18 according to the control signal to process the captured image. An image processing section 17 for dialing the incoming call number according to a control signal, and a dialing section 14 for transmitting at least one of a transmission history or a camera captured image or a terminal position coordinate value, and a transmission history or camera imaging. RF processing unit 15 for wirelessly processing at least one of the image or the terminal position coordinate value, and transmits over the antenna to the dialed incoming telephone number over the air.

The alarm mode may be set in the terminal itself or an important article (equipment) that the user is concerned about theft or loss. When the alarm mode is set, the setting time (10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, 1) Minutes, etc.) and the connection method in the alarm mode (at least one of the loudest ringtone, dialing to a designated telephone number, and transmitting a voice / text message after dialing, transmitting a position coordinate value, and transmitting a captured image).

Therefore, when the alarm mode setting key is input, the controller 10 sets the alarm mode after the set time elapses. In addition, when the alarm mode is set, the control unit 10 outputs a control signal for the connection method when the vibration detecting unit 11 or the opening / closing detecting unit 12 notifies the vibration or the opening / closing change of the terminal. However, even when a valid terminal user (terminal owner) attempts to release the set alarm mode, there may be a change in the vibration or opening / closing of the terminal. Therefore, when the vibration or switching of the terminal is changed in the alarm mode, Rather than outputting the control signal immediately, it is desirable to set a minimum waiting time for user authentication when the alarm mode is to be released (that is, the time for which the alarm mode release key is pressed and the password can be authenticated). This is because unnecessary warning sounds and call waste for canceling the alarm mode generated by a legitimate user can be prevented.

However, in the alarm mode setting state, the minimum time (about 2 to 3 seconds) to press the alarm mode release key and the alarm mode release key when the vibration or opening and closing of the terminal is changed extends the output of the control signal for the connection method. It is also worth considering that the password is separated by the authentication time (about 5 to 6 seconds).

Therefore, the minimum time that the alarm mode release key can be pressed if the alarm mode release key is not pressed within the minimum time (about 2 to 3 seconds) that the alarm mode release key can be pressed when the vibration mode of the terminal is changed or opened while the alarm mode is set. After 2 ~ 3 seconds, output the control signal for the connection method, and if you press the alarm mode release key within the minimum time (about 2 ~ 3 seconds), you can press the password to authenticate (about 5 ~ 6 seconds). After the extension, it is preferable to output the control signal for the connection method only when the authentication fails, when the authentication is successful, without outputting the control signal for the connection method.

The alarm mode on / off key may be set to one of the existing keypad (0 ~ 9, *, #), navigation keys, function keys, and side direction keys for the alarm mode on / off button, or a separate key on the terminal. You can also add a new one. You can also configure the menu function as an index, or if you know the shortcut key, you can set the alarm mode by pressing the shortcut key "# SON + confirmation key", and press the shortcut key "# SOFF + confirmation key" to cancel the security mode setting. It may be.

The present invention applies a vibration detection sensor that can detect vibration in a portable terminal such as a mobile communication terminal (including a mobile communication terminal with a camera), if the user needs to put it in a protected object (important goods or equipment, vehicle, etc.) In order to prevent the terminal itself from being lost or stolen, if the alarm mode is set, the alarm mode is set after a set time (for example, 30 seconds), and the vibration detecting unit 11 detects the vibration of the terminal and detects the vibration. The result is notified to the control unit 10, and the control unit 10 outputs a control signal for the connection method after the minimum waiting time for releasing the alarm mode. That is, a control signal to send an alarm for an abnormality, a control signal to send to a specified telephone number, a control signal to inform the detection result to a predetermined number, a control signal to transmit a position coordinate value to a predetermined number, and drive a camera to capture an image. At least one of the control signals for transmitting the image to a predetermined number is generated.

Therefore, in response to the control signal to send the abnormality occurrence alarm of the control unit 10, the alarm generating unit 16 generates the alarm history (for example, warning message, siren, etc.) with the maximum output.

In addition, according to the control signal to call to the designated telephone number of the control unit 10, the dialing unit 14 automatically dials the designated destination number. At this time, the incoming telephone number may be a landline telephone number, a wireless telephone number, and other control centers (which may be relay servers or police stations, fire departments, security companies, etc.). When several incoming call numbers are designated in this way, according to the control signal of the control unit 10, the call number designated by the dialing unit 14 is simultaneously (wired telephone number: wireless telephone number: control center number, or landline telephone number). (Control center number, or wireless telephone number: control center number, etc.) or sequential call can be made sequentially. For example, sequential call, first call to the first designated wireless telephone number, and if the call fails, call to the second designated landline telephone number. It is possible to significantly reduce the probability of a call failure by sending a call to a control center when a call fails to the first and second designated wired / wireless telephone numbers. In addition, it is possible to designate several wireless telephone numbers to attempt sequential calls, and to consider calling a call to a control center when a call fails. In addition, it is also possible to increase the probability of a successful call by attempting to periodically transmit to the same telephone number (for example, 1 minute unit). If the call is successful, the incoming call of the voice or text message (for example, outsider invaded at 00 00 00 00 0 0 0 0 0 00) and camera image information (still image, video) It can also be sent to a phone number. In addition, when the GPS receiver 19 is mounted on the terminal, the position coordinate value may be transmitted to a predetermined telephone number.

Here, the reason for sensing and storing the detected moving object (object or person) by operating the camera and transmitting the stored image to the preset phone number is for securing evidence.

For the sake of understanding, in detail, in the alarm mode, when the control unit 10 generates a control signal according to a detection result (vibration or opening and closing of the terminal) of the vibration detecting unit 11 or the opening and closing detecting unit 12, Accordingly, the image processing unit 17 drives the drive IC (Integrated Circuit) of the camera 18 to perform image processing of the camera photographing information (image information) (image modulation process). That is, according to the camera driving signal, the camera 18 converts the image of the subject to be captured (intruder) into an electrical signal through photoelectric conversion, and the image processor 17 encodes the image signal of the subject to be captured. .

The vibration detecting unit 11 is operated by a DC power supplied from a power supply unit (not shown), and a vibration reaction sensor or the like may be used. Therefore, the vibration detection unit 11 outputs a predetermined detection signal when the vibration is detected, the detection signal is transmitted to the control unit 10, the control unit 20 for outputting the control signal for the connection method. On the other hand, the terminal without the vibration sensing unit 11 may perform the same function through the opening and closing detection unit 12 that can detect the opening and closing operation of the folder or flip.

The control unit (CPU) 10 controls the overall operation of the terminal and at the same time controls in the alarm mode according to the user's input. Then, the alarm control of the various components are provided.

On the other hand, the incoming call number stored in the memory 13, the transmission history (voice or text message) to notify the called party, the alarm history (voice message) for the intruder can be arbitrarily designated by the user. In addition, the memory 13 stores camera image information (still image, video) and terminal position coordinate values captured by the camera 18 in the alarm mode, and camera image information, terminal position coordinate values, and the like are designated to the designated telephone number. It may be transmitted along with the transmission history.

2 is a flowchart illustrating an embodiment of a method for preventing theft of a portable terminal according to the present invention.

First, the terminal user can set an alarm mode on the terminal itself or an important item (equipment) that the user may be stolen or lost.When setting the alarm mode, the set time (10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds, 1 minute, etc.) and specify the connection method in the alarm mode (at least one of the loudest ringtone, dialing to the specified phone number, sending voice / text message after dialing, transmitting position coordinates, and sending captured images). Put it.

When the alarm mode setting key is input from the user, the controller 10 sets the alarm mode after the entry time (set time) to the corresponding alarm mode (201).

In this state in which the alarm mode is set (201), when the vibration detection unit 11 or the open / close detection unit 12 notifies the vibration or the opening / closing change of the terminal, the control unit 10 for user authentication when the alarm mode is to be released. After the elapse of the minimum waiting time (ie, the time when the alarm mode release key is pressed and the password is authenticated), a control signal for the connection method is output (204). At this time, as a control signal generated when the control unit 10 detects the vibration or opening and closing of the terminal, a control signal to send an abnormal alarm, a control signal to send to a specified telephone number, a control signal to inform the detection result to a predetermined number At least one control signal is generated from a control signal for transmitting the position coordinate value to a predetermined number and a control signal for driving the camera to transmit the captured image to the predetermined number.

Therefore, in response to the control signal to send the abnormality occurrence alarm of the control unit 10, the alarm generation unit 16 generates the alarm details (for example, a warning message, a siren, etc.) at maximum output (205).

In addition, according to the control signal to call the designated telephone number of the control unit 10, the dialing unit 14 automatically dials to the designated destination number (206). At this time, the transmission history of the voice or text message (for example, outsider invaded 0 00 00 0 0 00 00 0 0 00 00 0 0 00 00) and camera image information (still image, video) captured by the camera 18 May be transmitted to the designated incoming call number, or if the terminal is equipped with a GPS receiver 19, the position coordinate value may be transmitted to the predetermined call number (207).

On the other hand, even when the user wants to release the set alarm mode, even a legitimate terminal user (terminal owner), because there may be a vibration or change of the terminal of course, the minimum waiting time for user authentication when the alarm mode is to be released (that is, In this case, the time required for authentication by pressing the alarm mode release key and pressing the password should be considered.

Accordingly, if the alarm mode release key is not pressed within the minimum time (about 2 to 3 seconds) that the alarm mode release key can be pressed (202) when the vibration or opening / closing change of the terminal (201) is performed in the state of the alarm mode is set (201). After the minimum time (about 2 to 3 seconds) to press the alarm mode release key (208,209) outputs the control signal for the connection method (204), and releases the alarm mode within the minimum time (about 2 to 3 seconds) Press the key to extend the time (5 ~ 6 seconds) that can be authenticated by pressing the password, if the authentication is successful (210) releases the set alarm mode without outputting the control signal for the connection method (211) In operation 204, the control signal for the connection method is output only when authentication fails (210).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

According to the present invention as described above, by setting the alarm function, it is possible to protect and secure the evidence from the loss or theft of the terminal itself or important items (equipment) through the alarm and photographing, etc., the position of the terminal through the GPS function There is an effect that can be pinpointed.
