Hereinafter, with reference to the accompanying drawings will be described in detail the anti-theft device and anti-theft method of a portable computer of the present invention.

2 is a block diagram schematically showing the configuration of an anti-theft device of a portable computer according to the present invention.

As shown, the key input unit 10 is the first installation of the anti-theft program according to the user's preference or when the conversion after installation, the sensitivity of each sensor of the sensor 20 to be described later, the reaction waiting time after detecting theft attempt, Key signal for inputting various parameters that can be set by the user, such as alarm sound level, alarm sound type, warning screen, portable communication device number, anti-theft mode setting password, and key for executing the anti-theft mode and releasing the anti-theft mode This is the part where the signal is input.

The detection unit 20 includes a vibration detection sensor 21 for detecting vibration according to horizontal / vertical movement of the portable computer, a movement detection sensor 22 installed at the bottom of the portable computer to detect falling from the floor, and a portable computer. And an open / close detection sensor 23 for detecting the opening and closing of the camera, and a camera 24 for detecting and photographing a moving object under the control of the controller 30, which will be described later, when an attempt is stolen by another person.

The controller 30 controls the installation of the anti-theft program according to the user's key signal through the key input unit 10, and when the anti-theft mode execution key signal is input through the key input unit 10, the overall information of the system currently in use. At the same time, it controls to keep the power state on.

After the predetermined time (for example, 5 seconds) elapses, the anti-theft mode is activated, and the sensing data input from each sensor of the sensing unit 20 is compared with the preset data and the keyboard / mouse / touch pad It is determined that there is an attempt of theft by another person by detecting the operation / detachment of various peripheral devices, and the like. The alarm sound generation control signal and the warning screen display control signal are output to the warning unit 40 which will be described later, according to a preset anti-theft program.

In addition, when the portable computer is equipped with a camera 24, the controller 30 outputs a control signal to store moving objects at predetermined time intervals and store them in the memory unit 60, which will be described later, in the case of theft attempt in each case described above. When the system is currently connected to a communication network such as the Internet, a specific server (eg, a server configured to store photographing information and the burglar alarm signal stored in the memory unit 60 according to the anti-theft environment preset by the user) is established on the Internet. For example, it can be sent to a server operated by an anti-theft program vendor to warn of theft attempt from a particular server to a user's portable communication device.

At this time, the control unit 30 includes a password required for releasing the anti-theft mode, which is input when the anti-theft program is installed by the user, the sensitivity of each sensor 20, the waiting time for the reaction after theft attempt is detected, the alarm sound level, and the alarm sound. Various parameters that can be arbitrarily set by the user, such as type, warning screen, and portable communication device number, are set in advance. Among the above-described detection units 20, the sensitivity of each sensor and the reaction waiting time after detecting theft attempt are divided into several steps. Can be set.

On the other hand, the control unit 30 determines that theft is terminated by a forced power cut, not by the termination of the key signal input for the anti-theft mode release, and waits for the Internet to be used again after the system is restarted. When connected to the system, the system can transfer the system information such as IP address, computer name, user name, and the like to the data captured by the camera to the specific server without the theft aware.

Although not shown in the drawings, a specific server established on the Internet to support theft prevention manages IDs and passwords registered by each user when installing theft prevention program, and is transmitted from a portable computer when theft is attempted. According to the shooting information and the burglar alarm signal, the user's portable communication device is warned that there is a theft attempt, and when the portable computer holder (theft) uses the Internet, the system information automatically transmitted from the portable computer is displayed. It delivers the portable computer to the stolen user.

The warning unit 40 outputs an alarm sound through the speaker with the type and size of the alarm sound according to a preset anti-theft program according to the alarm sound generation control signal output from the control unit 30 when an attempt is stolen by another person. The generator 41 and the display unit 42 for displaying a screen for warning that theft attempt is made according to the warning screen display control signal output from the controller 30 when the warning screen is set.

In addition to the above-mentioned alarm sound generation and warning screen output, the warning unit 40 may execute a specific program designated by the user under the control of the control unit 30 when attempted theft by another person.

The power supply unit 50 supplies the driving power of the portable computer, and when the anti-theft mode is executed, the power supply unit 50 maintains the on state according to the control signal of the controller 30 until the anti-theft mode release key signal is input.

That is, even if the power switch is operated by another person to cut off the power after the anti-theft mode is executed, the on state of the anti-theft mode is maintained under the control of the controller 30.

The memory unit 60 stores an image captured by the camera 24 under the control of the controller 30.

Next, the operation of the anti-theft device and anti-theft method of the portable computer according to the present invention configured as described above will be described in detail with reference to FIGS. 3 and 4.

3 is a flow chart showing in detail the flow of the anti-theft method of a portable computer according to the present invention, Figure 4 is a flow chart showing in detail the flow at the time of incomplete termination of the portable computer according to the present invention.

First, in order to install the anti-theft program on the portable computer, the user inputs the anti-theft mode release password through the key input unit 10, the sensitivity of each sensor of the detection unit 20, the reaction waiting time after detecting the theft attempt, the alarm sound level, and the alarm. Various parameters such as a sound type, a warning screen, and a portable communication device number are set and input (S1).

In this case, the various parameters set by the user in the above-described step S1 may be reset by changing various parameters according to the anti-theft environment desired by the user before executing the anti-theft program.

In addition, although not shown in the drawings, in addition to various parameters arbitrarily set by a user when installing an anti-theft program, the anti-theft program is prepared in case the portable computer is forcibly stolen by another person in the anti-theft mode. In the event of theft, you agree to send your system information, such as your IP address, computer name and user name, to a specific server on the Internet, and if you agree to transfer system information, enter your ID and password to connect to a specific server on the Internet. Provide for input.

When the transmission, ID, password, and the like of the system server are input by the user as described above, the controller 30 sets up the contents input by the user and registers them with a specific server of the Internet.

The above-described system transfer agreement and ID / password registration process will be described again later. However, if a user enters an ID and password registered in a specific server using another computer after the portable computer is stolen, the system information transmitted from the portable computer is displayed. This is to check where your portable computer is being used.

Now, after the program installation work required to perform the anti-theft mode is finished through the above-described step (S1), the user may execute the anti-theft mode if necessary while using the portable computer.

In this case, the controller 30 determines whether a key signal for setting the anti-theft mode is input through a keyboard or a mouse by the user (S2), and when the anti-theft mode setting key signal is input, the current portable computer is connected. At the same time as checking the state and operation state is controlled to maintain the power state of the on state (S3).

That is, the controller 30 checks the use program at the time when the anti-theft mode setting key signal is input by the user or various peripheral devices connected to the portable computer.

As such, after checking a connection state and an operation state of the current system and maintaining a power state, the controller 30 operates an anti-theft mode (S4).

In this case, the reason why the anti-theft mode is operated after a predetermined time elapses is to give the user time to contact the portable computer for a predetermined time after the anti-theft mode is set.

After the anti-theft mode is activated, the control unit 30 detects the data input through the vibration sensor 21, the movement sensor 22, and the opening / closing sensor 23 of the sensor 20 and the above-described steps ( The parameters set in S1) are compared (S5).

In other words, it detects whether the display unit 42, such as an LCD panel, is opened or lifted by the other person in order to use the portable computer.

When the data currently sensed and input by the comparison result detection unit 20 of the above-described step S5 exceeds a parameter set by the user, the controller 30 determines that there is an attempt of theft by another person, and generates an alarm sound. While outputting the alarm sound generation control signal to the unit 41, and outputs the display control signal to the display unit 42 to output the alarm sound through the speaker and to display the warning screen (S7).

However, when the data currently sensed and input from the comparison result detection unit 20 of the above-described step S5 does not exceed a parameter set by the user, the controller 30 may control a keyboard, a mouse, a touch pad, a power switch, and the like. It will detect whether the manipulation or the attachment / detachment of various peripherals is made (S6).

When a result of the sensing is performed by another person, such as a keyboard, a mouse, a touch pad, a power switch, or when mounting / removing various peripheral devices, the above-described alarm sound is output and a warning screen is displayed (S7).

In addition, when the portable computer is provided with a camera 24, the control unit 30 outputs an alarm sound and displays a warning screen at the same time as in step S7 described above when an attempt is stolen by another person. In step S8, the moving object is photographed at a predetermined time interval and stored in the memory unit 60 (S8).

On the other hand, when the anti-theft mode is executed through the above-described step (S2) there may be a case that the portable computer is connected to the Internet.

In this case, when theft attempt by another person is detected through the above-described steps (S5) and (S6), the controller 30 automatically presets the user to a specific server opened on the Internet in addition to the alarm sound output and the warning screen display. According to the anti-theft environment, and transmits the shooting information and the burglar alarm signal stored in the memory (60) (S9).

Therefore, in a specific server, the user can immediately confirm that the portable communication device of the previously registered user has been stolen by the user based on the information transmitted from the controller 30.

As described above, while there is an attempt of theft by another person and the alarm sound, the warning screen, and the like are continuously output through the above-described steps (S7 to S9), the controller 30 continuously determines whether the anti-theft mode release password is input ( S10).

If the password is input as a result of the determination in step S10 described above, the currently set anti-theft mode is released (S11).

On the other hand, as described above, the anti-theft mode may be incompletely terminated by a forced power cutoff by another person during theft, not by the termination of a key signal input for releasing the anti-theft mode while the anti-theft mode is being performed.

In this case, the portable computer determines that the portable computer has been stolen by another person and determines whether the system is rebooted as shown in FIG. 4 (S21).

When the system is rebooted as a result of the above-described determination (S21), the controller 30 recognizes that theft has occurred by another person, and reads system information currently being used (S22).

As such, after reading the system information currently being used, it is determined whether the system is connected to the Internet (S23), and if the system is connected to the Internet and is in use, the system information read in the above-described step (S22) is opened on the Internet. It transmits to the specified server (S24).

Therefore, when the user who stolen the portable computer later accesses a specific server by using another computer (S25), if the user searches for the information about the portable computer, the user can check the system information of the stolen portable computer. (S26).

Therefore, it is possible to identify who the stolen portable computer is being used by and help to recover the portable computer.

As described above, according to the anti-theft device and anti-theft method of the portable computer of the present invention, in the process of installing the anti-theft program by the user when the system is forcibly operated or moved by another person after the anti-theft mode is executed Various alarm devices such as set alarm sound output, warning screen display, camera shooting, and warning to a portable communication device through the Internet operate to prevent theft of a portable computer in advance.

Also, even if a user is stolen from the portable computer, if the stolen person uses the Internet through the computer, the system information is automatically sent to a specific server on the Internet. Being able to verify that it is being used has the advantage of helping to find stolen portable computers.
