In addition, the computer 110 provides a power saving mode that operates to minimize the energy consumed by the computer. Here, the computer 110 may be a network separated computer physically separated from a network for security purposes. In this case, the computer 110 may not have a communication module for communication through the wired / wireless network. Also, log-on indicates a state in which the computer 110 can be used, and logo-off indicates a state in which the computer 110 can not be used. When the computer 110 enters a password preset by a user who has a use right for the computer 110 in a log off state, the computer 110 is switched to the log on state, If it is not used for more than the time, it will be in the logoff state. The power save mode may be performed when the computer 110 is in the logoff state.

The security device 120 is for security and energy saving of the computer 110 and includes a communication module 121, a control module 122 and an interface module 123.

The communication module 121 transmits and receives short-range wireless signals to and from the portable device 130 using a short-range wireless network. For example, the communication module 121 may include a Bluetooth module, a WiFi (Wireless Fidelity) module, a NFC (Near Field Communication) module, and an RFID (Radio Frequency Identification) module.

The Bluetooth module can transmit and receive a Bluetooth signal including a code for pairing between the portable device 130 and the security device 120. [ Here, the code may include an ID of a user, an ID of a portable device, and the like. The ID of the portable device may be a phone number of the portable device when the portable device 130 is a device to which a telephone number is assigned, such as a smart phone or a mobile phone. The WiFi module can receive a WiFi signal including a predetermined password through communication with the portable device 130 within the WiFi communication range. The NFC module and the RFID module may receive a signal including a predetermined password (or code) in communication with the portable device 130 when the portable device 130 approaches the security device 120 within a predetermined distance .

When the portable device 130 is authenticated, the control module 122 can control the log-on operation in response to a password for log-on to the computer 110 in cooperation with the portable device 130. [ Conversely, the control module 122 does not establish a link with the portable device 130 because the short distance wireless signal is not received from the portable device 130, or the code (or password) included in the short distance wireless signal does not match The security program may be executed to control the computer 110 to log off. That is, the control module 122 authenticates the portable device 130 when the local wireless signal is detected from the portable device 130 so that the computer 110 can be logged on. However, It is determined that there is no user and the computer 110 is logged off so that the computer 110 can be secured.

For example, the control module 122 may control the log on / off of the computer 110 as shown in Table 1 below.

Previous state Current Status Control detection detection Log on (turn off security) detection Non-detection Log off (security settings) Non-detection detection Log on (turn off security) Non-detection Non-detection Log off (security settings)

Referring to Table 1, the control module 122 can determine whether a short-range wireless signal from a portable device (pre-registered or authenticated portable device) is detected every predetermined period, The computer 110 may generate and send a control signal to the computer 110 so that the computer 110 can log on (turn off the security) or logoff (set the security) according to the current state.

Meanwhile, the control module 122 may control the power saving mode of the computer 110 so that the energy consumed by the computer 110 may be reduced. For this purpose, the control module 122 may control a timer for the power saving mode. The control module 122 controls the operation of the computer 110 when a password for logon of the computer 110 is input or when a user inputs a password to the computer 110. In the case where the remote wireless signal from the portable device 130 is detected and interlocked with the portable device 130, The controller 100 controls the computer 100 to operate in the normal mode without operating in the power saving mode by controlling the timer to be started or restarted. On the contrary, if the short distance wireless signal is not received from the portable device 130 for a predetermined time or the connection disconnection state with the portable device 130 is maintained for a predetermined time or longer, the control module 122 expires the timer ) To operate in the power saving mode. In other words, the computer 110 operates in the power saving mode when the timer for the power saving mode expires, and operates in the normal mode when the timer is started or restarted.

The interface module 123 provides a physical interface for connection to the computer 110, log on / off function of the computer 110, and control of the power saving mode. For example, the interface module 123 may include a USB interface, a PCM interface, a serial interface, a LAN interface, and the like, and may be connected to the computer 110 through the interface.

The security device 120 according to the present invention may be physically installed in the computer 110 or connected to the computer 110 through the connection between the interface module 111 of the computer 110 and the interface module 123 of the security device 120. [ To provide security functions and energy saving functions.

The portable device 130 includes a communication module 131 for short range wireless communication and an authentication module 132 for user authentication. The portable device 130 may be implemented in various types of devices such as a smart phone including a short-range wireless communication function, a portable personal authentication device, and the like.

For example, the authentication module 132 may perform user authentication through the mobile communication network using the wireless communication function of the portable device 130. [

When the user authentication is successful by the authentication module 132, the communication module 131 may transmit the short-range wireless signal including the preset code (or password) to the security device 120. [ Therefore, even if a user (a third party) who does not have the right to use the computer acquires the portable device 130, if the authentication of the user fails by the authentication module 132, the interoperation between the portable device 130 and the security device 120 fails The computer 110 can not be used. Therefore, according to the present invention, since the computer 110 can be used only when the authenticated user carries the portable device 130 registered in advance (authenticated), the security is maintained, and based on the short- Since the power saving mode of the computer 110 is controlled, the energy consumed by the computer 110 can be saved more effectively.
