As shown in FIG. 2, the host computer 150 is provided with a USB mode driving program 160 for performing the remote control process by the USB device 100, and is changed every time the power is turned on. In the case of a host computer provided with IP information, the host computer 150 is configured to be connected to the DDNS service providing terminal 170 to search for and provide a dynamic IP of the host computer.

In addition, the USB device 100 and the host computer 150 store the authentication key data (for example, a key value formed by combining a unique serial number and registration number of the USB device) and host information for user authentication. do.

In addition, the LAN card 180 mounted on the host computer 150 preferably supports a function of automatically booting up (Wake up on LAN).

The operation of the present invention configured as described above will be described with reference to FIGS. 1 to 5.

First, in a state where the host module of the USB device 100 is installed in the host computer 150 to be remotely controlled, a computer provided to an external environment such as an office or a PC room where an Internet infrastructure is constructed, or a portable laptop computer / personal information terminal. If the user wants to control his or her host computer (home PC or company PC) 150, the user mounts the USB device 100 to the USB port installed in the guest computer 10.

When the USB device 100 is mounted, the guest computer 10 recognizes the mounting state of the USB device 100 and automatically performs initial configuration for remote control. For example, a CD-ROM is provided. When installed, the program is recognized by a driving program and the program is executed. After the program capable of executing the USB device 100 is executed, the USB device 100 searches for the host computer 150 to be remotely controlled. do.

In the search process of the host computer 150, the IP address of the host computer 150 is normally searched, and then the connection process with the guest computer 10 is performed. The retrieval process occurs differently according to the dynamic IP provisioning conditions.

Referring to FIG. 4, first, when a changed IP is provided every time the host computer 150 is turned on (this is mostly a computer installed in a home connected to a high-speed Internet network) (steps 200 and 202). Yes), the user is given a domain name from the DDNS service providing terminal 170 of the company by performing a registration procedure to the company that performs the IP search process (step 210).

In this state, the host computer 150 is turned on and connected to any IP generated by verifying it in association with the given domain name (step 212), and the host is generated as the generated IP through the service of the DDNS service providing terminal 170. The computer 150 is searched to connect the host computer 150 to the guest computer 10 where the remote control request is generated (step 214).

However, if the DDNS service is not provided (NO in step 210), the IP search operation is executed using the NET BIOS for the designated IP information, and the host computer IP matching the MAC address information is found and connected. (Steps 216 to 220). That is, since IP information such as an IP address and a net mask is stored in the host computer 150 and the USB device 100, in this case, the remote control request is first stored in the USB device 100. When the IP information is transmitted through the network band, it is determined whether the transmitted IP information and the MAC address information of the host computer 150 match, and then the host computer 150 matching the detected IP computer is connected. .

On the other hand, when a dynamic IP is not provided (this applies to a computer in an environment where a network can be used through a predetermined server), the computer can be powered on and driven, and then the guest computer and the host computer can be interconnected. (Steps 206, 208).

When the host computer 150 connected to the previously stored host information or remotely connected to the guest computer 10 equipped with the USB device 100 is searched according to the above process, the USB device 100 is secured. The user authentication key stored in the encryption module of the processing unit 112 is transmitted to the host computer 150, and the response data for the transmitted user authentication key is retransmitted from the host computer 150 to the USB device 100 to authenticate the user. Perform an encryption procedure on the.

When the user authentication is completed according to the encryption process, the synchronization between the USB device 100 and the host computer 150 is completed in order to perform a remote synchronization service, and then the USB device 100 actually operates the host computer 150. The host computer 150 requests a remote control operation for use.

In response to the request operation, the host computer 150 drives the USB mode driving program 160, and then detects a command for calling a function of a display device in the graphic engine unit of the host computer 150 although not shown in the drawing. After initial data including images and texts is optimized for remote control, the data is transmitted to the guest computer 10 to display the initial data transmitted from the guest computer 10.

In addition, the user performs a task to be performed on the basis of the displayed initial data. When the user transmits a control command such as data input through a keypad or input data according to a mouse driving, to the host computer 150, the host The computer 150 analyzes the transmitted control command and processes the corresponding operation.

For example, since the initial screen of the host computer 150 is displayed on the display unit of the guest computer 10 according to the remote control operation, the user calls the software installed in the host computer 150. When the work is to be stored, and data needs to be stored at the time of work, it is possible to store it on the hard disk of the host computer 150 instead of the guest computer 10.

In addition, even when conducting cyber securities transactions or Internet banking, the user may directly install a host computer using a certificate and a program already installed in the host computer 150 without installing a certificate and a program in the guest computer 10. You can work on Internet banking following the same process as you do on 150.

Therefore, the user can control his or her host computer at a remote location with the USB device 100 mounted on the guest computer 10 instead of his computer.

Meanwhile, in addition to being able to perform various remote operations as described above, power interruption of the host computer 150 may be performed remotely, which will be described with reference to FIG. 5.

First of all, in order to interrupt the power, the host computer 150 must be connected to a power source and a function for automatically booting up the LAN card 180 mounted on the host computer 150 must be supported. do.

In such a state, the guest computer 10 searches for its host computer 150 to be controlled remotely according to the above-described IP search process (step 300), for example, stored in the USB device 100 and transmitted. The host computer 150 is searched by using the IP information (including IP address, Mac address information, etc.) of the host computer 150 and MAC address information as unique information given to the LAN card.

Thereafter, the USB device 100 reads data including the control command for turning on the PC power by the power processing unit 114 from the memory unit 120 and transmits the data to the host computer 150. In operation 302, the LAN card 180 mounted on the host computer 150 is activated by receiving the control command and calls on the operating system of the host computer 150 to turn it on. Steps 304, 306). That is, the LAN card 180 reads a boot program by a function of turning on the host computer 150 by receiving a power-down command, and the boot program stores an operating system. It is called to the device to start up or to perform the initial setting work so that the host computer 150 can operate.

Then, in the on state of the host computer 150 in step 308, as described above, the host computer 150 is remotely controlled to complete a series of operations such as file sharing or file transmission and reception (step 310).

Thereafter, when the USB device 100 is detached from the USB port of the guest computer 10, the remote control mode is released. In this case, no program or data is stored in the guest computer 10 in relation to the remote operation.

On the other hand, even if the modified embodiments different from the contents described in the present invention should not be understood individually from the technical spirit or prospects of the present invention, it should be belong to the claims attached to the present invention.
