Description

Terminal security system and method using wireless mouse

The present invention relates to a terminal security system and method using a wireless mouse, and more specifically, to add a simple configuration without having an expensive device in the wireless mouse, prohibiting the use of a terminal by a non-regular user for a terminal such as a PC or a notebook. The present invention relates to a system and a method capable of implementing a security function.

Recently, due to the rapid development of the computer industry, personal computers have been widely used in most fields, and various administrative business documents in the public field are also stored as computer electronic files.

Moreover, the Internet has not only been widely used among the general public, but it has also been a long time since the important information is sent and received by e-mail instead of the existing facsimile.

And a computer requires an input device to output a large amount of important information stored on a monitor screen or a printer.

As is well known, the input device of a computer includes a keyboard for inputting user-defined command operations and data, a mouse, and the like, which can more easily transfer command data to a computer than the keyboard. The generated data representation data is serially transmitted to the interface of the computer to execute the program.

Recently, as the computer has developed into a user-oriented operating system, an operating system incorporating the element of graphics has emerged, and a computer is essentially equipped with a pointing device. In particular, mice such as serial and P / 2 types and a bus mouse are inevitably used externally.

This mouse is an input device used to select one object among various objects on the screen, that is, icons of various kinds. It is designed to switch to, boot the computer, etc. with one click.

In order to output the information stored in the computer using the mouse, the user first moves the pointer of the mouse to one of the various types of icons displayed on the screen while the computer enters the security maintenance, and then the left or After the program is executed by pressing the right-click button, the stored information corresponding to the icon is displayed on the screen or is output to the printer and printed through an additional operation.

However, the conventional mouse has an advantage of making the computer easier to use by an operation of 'click', but since it is not equipped with an information security function in itself, it does not identify a regular user in a general environment.

This makes it possible for non-regular users, ie non-regular users of the computer, to easily access information inside the computer while the regular user is away from the computer. For example, frequently rebooting a secured computer through a mouse and leaking important information stored frequently occurs.

In addition, the monitor is a device that processes the video signal provided from the computer and displays it on the screen. As the user performs various tasks or personal tasks while watching the monitor screen, there is also a risk of leakage of personal information. have.

It is also necessary to prevent young children from using the computer for too long for games or other reasons. Of course, there is a function that turns off the screen after a certain period of time when the user is away due to the power saving mode, but this does not mean that the normal screen display is resumed immediately by a simple operation of moving a mouse or pressing a key of a non-user. .

As described above, the conventional technology does not have a function such as allowing only a specific user to display the screen of the monitor, which causes a problem of personal information leakage and inconvenience in use.

In order to solve these problems, a mouse has been devised and commercialized using a fingerprint recognition module mounted on a general mouse to identify a predetermined user at boot time and use it as an encryption device for determining booting of a computer.

However, the mouse equipped with the fingerprint module has the inconvenience of correctly grounding the registered finger to the fingerprint module every time the user works through the computer. In addition, the mouse is not correctly grounded to the fingerprint module. In this case, it is not possible to identify the user and cause a malfunction. Also, it is pointed out that the price of the mouse increases due to the installation of an expensive fingerprint recognition module.

Moreover, most of these security features have been applied to wired mice. There is no example of applying a security function to a wireless mouse, the use of which is gradually increasing in recent years, and thus there is a need for the present invention.

1 is a diagram illustrating a wireless mouse and a terminal in a security system according to a preferred embodiment of the present invention, and FIG. 2 is a block diagram showing a configuration of a security system according to a preferred embodiment of the present invention. 3 and 4 are operational flowcharts of a security system using a wireless mouse according to the present invention.

First, as shown in FIG. 1 and FIG. 2, three well-known buttons, namely, a left button 21 and a right button 22, are provided on the front of the wireless mouse 20 so as to perform a basic input function of the mouse. A wheel button 23 is provided, and a sensing means 24 for position tracking is provided on the back of the wireless mouse 20 which is grounded to a pad or an arbitrary bottom surface.

The sensing means 24 may be composed of a ball or an optical sensor. The left / right buttons 21 and 22, the wheel button 23, and the sensing means 24 may be used as a wireless mouse according to the present invention. 20 is the input device of the terminal 10, such as a wireless ball mouse, a wireless optical mouse, etc., and has a basic input function of a conventional wireless mouse. In addition, the wireless mouse 20 is provided with a communication module 26 connected to the central processing unit 25 to implement a wireless input function.

That is, in the wireless mouse 20, the central processing unit 25 receives a signal input from the left / right buttons 21 and 22, the wheel button 23, and the sensing means 24, and corresponds to the signal. Generates an input signal and applies it to the communication module 26, and a wireless signal corresponding to the mouse input signal is transmitted from the communication module 26 to the communication module 13 of the terminal 10 and inputted. An input function can be performed.

The wireless mouse 20 to which the present invention is applied may be, for example, an RF wireless optical mouse. The wireless mouse 20 is generally manufactured by selling a wireless transmitter, which is a communication module 26, and a battery, which is a power supply unit. It is becoming. In addition, in order to receive a signal transmitted from a wireless transmitter of a wireless optical mouse, the communication module 13 should be provided in the terminal 10. The communication module of the terminal may be a USB type wireless receiver, which is a USB port of the terminal. Easy to plug into the device for wireless use.

On the other hand, in the present invention, a separate security button 27 that is user-installable to one side outside the wireless mouse 20 is additionally installed, the security button is any place (before / after, up / down or left / outside the wireless mouse). Right side, etc.) may be provided in the form of adding a new dedicated button.

In addition, in the wireless mouse 20, the security button 27 is connected to the CPU 25 so that an input signal according to the operation of the security button 27 can be input to the CPU 25. Accordingly, the CPU 25 may detect a signal input according to the operation of the security button 27. Of course, as a user operation button for entering the security mode, instead of installing a separate security button, it may be provided in the form of commonly used by selecting one of the existing mouse buttons (left / right button or wheel button). In this case, the selected left button 21 is pressed for 2 seconds or more, the right button 22 is continuously clicked for a set number of times, or the wheel button 23 is pressed for more than a set time or a set number of times. Can be implemented in the form of applying the mouse operation method.

In addition, the central processing unit 25 detects an input of a signal (a user button manipulation signal for entering the security mode) according to the operation of the security button 27 (S11) or the left / right buttons 21 and 22 and the wheel. When the signal input according to the mouse operation is not detected from the button 23 (the existing mouse button) and the sensing means 24 for a predetermined time, that is, when the mouse operation is not detected for a predetermined time (S12), the security mode is entered. It is provided to generate a request signal to the communication module 26.

Here, for the sensing means 24 for the movement detection and the position tracking of the mouse 20, the central processing unit 25 determines the initial position value of the mouse from a signal input from the sensing means, and then the initial means from the sensing means. When a new position value signal that differs from the position value is input, it is detected that there is an operation by moving the mouse. Otherwise, it is determined that there is no mouse operation (security mode entry condition).

When the user's security button operation is detected as described above, or when a signal input according to the mouse operation is not detected from the left / right button, the wheel button, and the sensing means for a predetermined time, the wireless mouse 20 requests to enter the security mode. The signal is wirelessly transmitted to the terminal 10 (S13), and as shown in FIG. 3, the terminal 10 enters a secure mode (S14).

When entering the security mode, the central processing unit 14 of the terminal 10 receives the security mode entry request signal of the wireless mouse 20 through the communication module 13 to execute a program for executing the security mode of the terminal, The state of the display 11 is changed to a security screen to fix it, or to fix the state of the display to the current working screen state, or to fix the state of the working screen so that a password input window appears on the display (S15). .

At this time, the central processing unit 14 of the terminal 10 stops any mouse input and keyboard input except for wireless mouse input or keyboard input for password input in a secure mode state.

When the state of the display 11 is changed to the security screen, and when the state of the working screen is fixed, as shown in FIG. 4, when the user operates the security button 27 on the wireless mouse 20. The password input window on the program is displayed on the display by the signal transmitted wirelessly (S17). That is, when the user presses the security button 27 of the wireless mouse 20, the CPU 25 detects an input of a button manipulation signal in the mouse, generates a user authentication request signal, and generates a user authentication request signal. When the user authentication request signal is applied to the communication module 26 and transmitted wirelessly, the central processing unit 14 of the terminal 10 receives the user authentication request signal through the communication module 13 to check the state of the display 11. Change to the password request screen where the password input window is displayed.

Next, the process of releasing the security mode by the regular user in the security mode entry state of the terminal will be described.

First, in the security mode, a password input window displayed on the display 11 by a program of the terminal 10 can be selected by mouse operation so that a user can input a preset password by a mouse operation or a keyboard operation. Numeric selection box with numbers displayed, and a password display box in which the number entered by mouse or keyboard operation is displayed as a special symbol, the mouse cursor in the password input window when moving the wireless mouse 20 in the security mode The program is programmed to be mobile only. In addition, the program is programmed in the password display box so that the cursor movement with the display of a special symbol such as '*' when the keyboard is input while the prompt is displayed is implemented.

Then, after the password is input as described above, the central processing unit 14 of the terminal 10 is a password entered by the user in the password input window of the display 11 using the wireless mouse 20 or the keyboard 12. It is determined whether it matches the set password (S18).

Subsequently, if the input password does not match the preset password, the security mode of the terminal 10 is maintained, and if the input password matches the preset password, the mouse function and keyboard function are stopped and the screen is fixed. Release the security mode, such as to release (S20), and allows the normal terminal 10 to work.

At this time, the user can re-enter the password up to a set number of times, for example, three times. In other words, if the password entered in the password input window matches the preset password and judges that the password does not match, it can be re-entered. If the wrong number of passwords does not exceed three times, the password can be re-entered. (Keep the password input window displayed) (in the S17 state), and if more than three times, the security mode such as mouse stop function, keyboard function stop, and display screen lock are maintained. In this case, the password input window may disappear from the display screen (it is just before S16), and the user again operates the security button 27 of the wireless mouse 20 so that the password input window is displayed on the display 11 of the terminal 10. You should have a new one on).

Thus, in the present invention, when the user simply presses the security button provided in the wireless mouse when the user is away from the terminal for a while, or when the user is away from the terminal for a certain time, the input of the wireless mouse is stopped. Security mode entry request signal is received wirelessly, the user enters the security mode set in advance by the pre-installed program, and after the user returns to enter the correct password using a wireless mouse security mode to enable the operation of the terminal To turn it off.

Of course, in order to implement the security function, the user must set a security function such as inputting and storing a password in advance through a keyboard operation or a mouse operation on the program. In this case, an input of a password (for example, 1234) may be directly input through a menu screen of the program or may be input through a numeric key of a keyboard.

In the above-described present invention, a series of programs and methods for interworking with signals transmitted from a wireless mouse (a security mode entry request signal and a left / right button operation signal, etc.) and a keyboard input signal for entering and releasing the security mode are described. Any method known in the art may be adopted without particular limitation.

In addition, in the preferred embodiment of the present invention, the wireless mouse 20 may be built in a USB memory device 28 that is connected to the central processing unit 25 and controlled to be driven, while allowing data input and output to and from the terminal 10. have. That is, as shown in Figure 2, the USB interface unit 28a provided to be connectable to the USB port of the terminal 10, and connected to the USB interface unit 28a as a storage means for storing the data through this data A USB memory 28b capable of input / output is built in. Accordingly, the wireless mouse of the present invention can be utilized as a USB memory device that can be used by connecting to a terminal.
