The present invention relates to a monitor security device and method, and more particularly, to a monitor security device and a method for managing the security of a computer through a monitor device that can enforce security on the monitor itself.

While environmental and energy issues are international topics, the issues related to screen protection and energy saving of monitor devices are also important in systems including monitor devices. For example, in a display device such as a monitor that is most widely used, a screen saver or Display Power Management Signaling (DPMS) is widely used as an effort to reduce power consumption. have.

The computer monitor power saving screen saver switches the monitor to screen protection mode for security if user input operation, such as a mouse or keyboard input operation, does not occur for a certain period of time. In order to recover it again, an input action is generated from the user or the user must enter a unique password.

DPMS is an international standard for reducing monitor power consumption, and defines four power states corresponding to the state of Advanced Power Management (APM) that is operated in a computer main body. APM is a power management processor for computers defined by Microsoft and IBM. The four states of the APM are on, stand-by, suspend, and off modes. In the on mode, there is a horizontal synchronizing signal and a vertical synchronizing signal inputted from the computer through a connector connected to the computer, a video signal is normally input and displayed on the screen, and all power is normally operated. In standby mode, there is no horizontal sync signal input to the computer through the connector, only vertical sync signal, and video signal is blanked so that nothing is displayed on the screen. to be. In suspend mode, there is only a horizontal sync signal input through the connector, there is no vertical sync signal, and the video signal is blanked so that nothing is displayed on the screen. The off state is a state in which the powers are all off, and there is no vertical and horizontal sync signal and the video signal is blanked to maximize power saving.

The above-described screen saver or DPMS-type monitor security and energy-saving modes are activated after sensing a user's input operation for a certain period of time, so that there is no response for immediate monitor security, especially in the screen saver mode for security. It is inconvenient to always enter a password for returning to.

For example, since the security function of the screen saver provided by the OS operates after at least 1 minute has elapsed, there is a risk of data leakage when the user is in a hurry.

SUMMARY OF THE INVENTION The present invention provides a method for a monitor security device that enables immediate screen protection and power saving by processing security functions directly in a monitor device.

According to an aspect of the present invention, there is provided a monitor security apparatus including an input unit for receiving a monitor security password from a user, a detection unit for recognizing whether the user inputs a password, and an interface unit for inputting and outputting user identification information from the password. If it is confirmed that the password is input from the detection unit, the control unit for reading the user identification information from the password through the interface to perform the on (on) or off (off) accordingly.                     

In addition, the monitor security method according to the spirit of the present invention for achieving the above object is the step of inputting the monitor security password from the user, recognizing whether or not the user's password input, if it is confirmed that the password is input from the detector, the interface And reading the user identification information from the password through a portion to perform on or off of the monitor accordingly.

By using the monitor security device and method according to the spirit of the present invention, by directly inputting and processing a password for identifying an individual user in the monitor device, security setting is easy, and immediate screen protection and power saving can be achieved. have.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the embodiments presented below, and new inventions can be presented by adding, limiting, deleting, adding, and the like within the scope obvious to those skilled in the art to which the present invention pertains. will be.

1 is a view showing the appearance of a monitor device according to the spirit of the present invention.

Referring to FIG. 1, a user may open a menu window on a monitor display window through a menu button formed on a portion of the monitor.

The security setting menu may be selected in the menu window to form a security system that operates independently from the PC. Since the security system is controlled and operated by inputting a password only through a monitor, security operation can be implemented in the shortest time.

Meanwhile, the user selects a security setting menu from the menu board and sets a password to be used in the future. The password can be changed according to the user's convenience, and a new password can be added or a conventional password can be deleted.

The set password can be input through an input unit of the monitor itself, not an input device such as a keyboard or a mouse of a PC, and a change, addition or deletion of a password is also input through the input unit of the monitor itself.

If the user needs to leave the place quickly while setting up security, the user can easily set up the monitor by pressing the menu setting button on the monitor and pressing the security setting button. Unlike conventional PCs, the complementary setting of the monitor is possible as soon as the complementary setting button is pressed, thereby reducing the risk of data leakage. To restart the monitor after the user has finished work, enter the password through the monitor's menu and use the PC again.

2 shows a schematic embodiment of a monitor security device according to the invention.

The monitor of FIG. 2 is connected to a predetermined system, such as a computer main body, and displays a signal generated from the system. In this embodiment, an object of the present invention is to implement security and power saving of a display using a password inputted by the monitor itself. do.

The monitor includes an input unit 140 for inputting a password including identification information of a user, an interface unit 100 for inputting and outputting information from a password input to the input unit 140, and a detection unit 110 for recognizing whether a password is input. When the password is recognized from the detector 110, the controller 120 reads personal identification information of the password through the interface unit 100 and accordingly includes turning on or off the monitor. .

The input unit 140 is a portion where a password is input through a button formed on a part of the outside of the monitor. The user can create and enter various passwords according to his or her inclination. For example, the user may create and use a password such as pressing the left button 2 and then pressing the right button 1.

Alternatively, a combination of numbers displayed on the password input window can be used as a password.

The password input through the input unit 140 is transmitted to the control unit 120 through the interface unit 100.

The interface unit 100 converts the information according to the encryption input and output into an electrical signal and transmits the information to the control unit 120 or forms a linkage with the input unit 140 according to the control signal of the control unit 120.

The detection unit 110 is composed of a circuit that changes the electrical state when the password is input or not input.

The controller 120 includes a password controller 121 and a microcomputer 122. The password controller 121 may read personal identification information of a password input through the interface unit 100, and provide the interface unit 100 with a predetermined command or a confirmation signal for the read signal. The microcomputer 122 controlling the display of the monitor receives an electrical signal for inputting or not inputting a password from the detector 110.                     

When the password is input, the power supply unit 150 supplies power to the input unit 140 to enable signal flow in the input unit 140. When the personal identification information from the input unit 140 is input through the password control unit 121, it is checked whether the information is that of the authenticated user, and the display of the monitor is controlled. That is, if the personal identification information is authenticated, the display of the monitor is controlled to be on, and if the personal identification information is not authenticated, the display of the monitor is controlled to be off.

The password control unit 121 or the microcomputer 122 first monitors personal identification information from the password of the input unit 140 by using an on-screen display (OSD) function of an external input device outside the monitor and the monitor. The registration function of storing the predetermined storage unit (or memory) 130 therein is performed. For example, when personally identifiable information is first read from a password and displayed in the OSD state on the monitor, the user may register the identification information by providing a registration function that also displays 'OK' and 'Cancel' as the OSD state on the monitor. Or cancel it. When the user presses 'OK' using the input unit 140 of the monitor, the personal identification information read through the password control unit 121 is stored in the storage unit 130. Similarly, the user may select the 'delete' function by displaying the OSD state so as to delete the personal identification information of the password that is already registered and stored in the storage unit 130.

In addition to the password set by the user, the storage unit 130 assists supplementation by storing information such as a user's work history and user program for each IP address, a log on / logout time, and a logged on user list after inputting a password. Can be.                     

The control unit 120 does not detect the signal of the encryption input state from the detection unit 110 or compares the information read from the input unit 140 through the interface unit 100 and the information stored in the storage unit 130 and the same information. If not, turn off the monitor display.

3 is a flowchart illustrating a monitor security method according to the spirit of the present invention.

Referring to FIG. 3, first, it is determined whether a password is input through an input unit of a monitor (step 200).

If it is determined in step 200 that the password has not been input, the monitor is turned off to block the display (step 210). If it is determined in step 200 that a password has been entered, personal identification information is read from the password (step 220). It is determined whether the identification information read from the password is the information of the authenticated user, that is, whether the user identification information stored in the storage 130 and the information read from the current password are the same (step 230). The display of the monitor is turned on (step 240) and the display of the monitor is turned off (step 250) if it is not the authenticated user's information. When the monitor display is turned off, the display or the monitor power can be turned off after displaying attention information such as not the user information authenticated to the user as the OSD display.

According to the monitor security device and method according to the spirit of the present invention, by directly inputting and processing a password for identifying an individual user in the monitor device, it is easy to set security, instant screen protection and power saving can be achieved. .
