1 is a conceptual diagram illustrating mobility of an application program using a virtual application execution support apparatus according to the present invention, and FIG. 2 illustrates an application program using a virtual application execution support apparatus for a desired application program according to the present invention. 3 is a flow chart for executing an application program in a virtual application execution support apparatus on any computer using the virtual application execution support apparatus according to the present invention. In FIG. 1, reference numeral 100 denotes a virtual application execution support device configured in a portable storage device, 110 denotes data, 120 denotes an application, 130 denotes a setting and control file, 140 denotes a user, 150 denotes a computer, 160 denotes a notebook and 170 Represents the server.

1 to 3, the present invention relates to a virtual application execution support apparatus 100 and an arbitrary computer 150, a notebook 160, a server 170, and the like before executing an application program. The application program is installed in the portable storage device to operate the storage device as a virtual application execution support device (S110; FIG. 2). In addition, the location information and the name are recorded until the installation is completed for the registry or configuration files created in the computer during the installation process (S120, S130). It uses a filter driver that monitors files and the registry to detect the creation of new files, the modification and deletion of existing files, and the creation and deletion of registry keys and the modification and deletion of registry key values. The newly created configuration files and registry information on the monitored computer are recorded in a file for transfer to a virtual application execution support device. The filter driver uses the file filter driver and the registry filter driver provided by the Windows Driver Development Kit provided by Microsoft.

After the installation is completed, the operation of reading and moving the list file generated during the installation process is automatically performed to put the registry and configuration files stored in the computer into the portable storage device (S140 and S150). After that, since the user needs information on the virtual application execution support device to execute the application, he / she requests file input / output requests necessary for the application execution (such as binary files such as application configuration files and dynamic libraries required for application startup). ) Put a program that redirects (redirection) to a virtual application execution support device. Finally, the virtual application execution support device can be automatically discovered by using the UPnP protocol on any PC without any additional setting, and the user authentication can be used to dynamically configure the storage network based on the iSCSI protocol. The program is put in the virtual application execution support device (S160).

In order to view the data stored in the virtual application execution support apparatus 100 or to execute an application while carrying the virtual application execution support apparatus 100, the UPnP protocol and the iSCSI client must be running on the computer. (S210; FIG. 3). That is, the computer must operate the UPnP protocol to automatically recognize the virtual application execution support device, and use the iSCSI client to run data or applications stored in the virtual application execution support device on the computer. After that, the user can use the application stored in the virtual application execution support device on the computer without installing or installing a separate connection.

Virtual Application Execution Support Device If a user wants to work with an application on a virtual application execution support device on a computer, the computer will automatically recognize the virtual application performance support device by operating the iSCSI server on the virtual application performance support device. To make a connection (S220, S230).

After the computer recognizes the virtual application execution support device, a program for operating an application program is executed (S240). It is designed to execute an application on a virtual application execution support device without installation. The computer recognizes that all the information necessary for the application is on the virtual application execution support device. Basically, it is a program that finds application information on the computer and generates an error when it cannot be found. It catches these errors and accesses the information necessary to execute the application back to the virtual application execution support device. . Due to the above method, the user can easily use a desired application program (S250, 260).

As described above, the present invention carries out a process of changing a configuration such that a portable storage device such as a virtual application execution support device to operate as the virtual application execution support device 100 (see FIG. 2), and a virtual application execution support device. Is divided into a process for the user to operate the application stored in the virtual application execution support device on any computer (FIG. 3). In addition, through the above process, the virtual application execution support apparatus is conceptually divided into a part having data and a part for operating an application program.

2 is a flowchart of a process of changing a configuration of a portable storage device such as a virtual application execution support device to operate as a virtual application execution support device. First, an application program installation is installed in the virtual application execution support device (S110 and S120). In general, the application files installed in the installation process of the application are virtualized by replacing the application with the virtual application execution support device instead of the computer that is basically set as the device to be installed in the installation of the application (S110 and S120). The application performance supporting apparatus 100 operates to be stored in the apparatus. However, some executable files that are entered into the internal properties of the computer or registry information necessary for the execution of the application are stored on the computer, not the virtual application execution support device, it is necessary to move it to the virtual application execution support device later. For this purpose, the program monitors and lists files or registry information stored in the computer during the installation process of the application program and records them as one temporary file (S130). After installation of the application program, the configuration file and the registry stored in the computer are read from the temporary file and transferred to the virtual application execution support device (S140, S150). In addition, an iSCSI server with the UPnP protocol standard is added to the virtual application execution support device to establish a connection with the computer during the movement process, and a program executed to access the virtual application execution support device with information necessary to execute the application. Put (S160).

When the above operation is completed, the user can use the application stored in the virtual application execution support device anytime and anywhere while carrying the virtual application execution support device.

3 is a flowchart illustrating a process for a user to operate an application program stored in a virtual application execution support apparatus on an arbitrary computer. In order to recognize the virtual application execution support device, the computer uses the UPnP protocol and establishes a connection with the virtual application execution support device using the iSCSI client (S210, S220, and S230). Thereafter, the virtual application execution support apparatus automatically allows the user to select which application among the applications inherent in the virtual application execution support apparatus to be made available on the computer. Then, the virtual application execution support device recognizes that the application is located in the virtual application execution support device, not the hard disk of the computer, and executes all the information related to the execution of the application from the virtual application execution support device (S240). , S250).

As such, when the virtual application execution support device ends the operation of the iSCSI server after the use of the present invention, the computer cannot use the application again, and the changed setting information or data is stored in the virtual application execution support device. It becomes (S260).

As described above, according to the virtual application execution support device and the method of using the device according to the present invention, a user can carry on a virtual application execution support device while continuing to work with any computer at any time and place. Will be. That is, the present invention provides the advantage that the user can carry around the work environment, eliminating the process of newly installing the application, and running the application program set for each individual.

Although a preferred embodiment of the present invention has been described in detail above, those skilled in the art to which the present invention pertains may make various changes without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Therefore, changes in the future embodiments of the present invention will not be able to escape the technology of the present invention.
