Description

Portable storage device

The present invention relates to a removable storage device for executing an application program without installation, and more particularly, to a removable storage device that can be used in a computer without an installation process stored in the removable storage device.

As peripheral devices are diversified in today's computer environment, there is a lack of physical space in slots connecting card-type devices used in conventional computer environments and ports connecting peripheral devices such as printers and mice. In addition, the lack of IRQs required to use peripherals in computer environments prevents the connection of many peripherals. To solve this problem, a new device connection method called Universal Serial Bus (USB) was created.

This USB makes it easy to connect peripherals from outside the computer via a hub. In addition, by creating peripherals based on the common interface provided by USB, developers can reduce the burden of developing new interfaces and conflicting with existing peripherals when creating peripherals, while using Plug and Play (PnP: Plug). and Play) can be supported more easily. This makes it easier for users to install peripherals without opening the computer without setting jumpers, IRQs, addresses, etc. These features are automatically detected by the computer's BIOS and operating system, and do not require installation.

On the other hand, recently developed removable storage devices using flash memory include many types of data movement users, presentation users, graphic workers, report students, and graphic academy portfolios. It can be used for work, attached to expensive equipment, used as a backup device, and also useful for archiving files that others should not see.

In the conventional portable storage device 10 using USB, the USB port 14a is integrally formed at one end of the housing 12. The housing 12 includes a USB interface unit 14, a controller 16, and a flash memory 18 for storing data. The removable storage device 10 using the USB includes a computer 20. USB port (not shown). The CPU 22 of the computer detects the connection of the USB device through the USB interface unit 24, searches for a driving driver for driving the connected USB device, loads it into the memory 26, and then uses a removable storage device using USB ( 10).

On the other hand, when new hardware is installed in the computer, the operating system (OS) detects the new device, requests information about the detected new hardware, and asks the user for driver installation so that the OS can use the new hardware. This process is called Plug and Play (PnP), which allows the operating system to find new hardware and automatically install the corresponding driver. However, the plug-and-play function did not install the desired driver properly, or in order to install a driver for hardware that cannot use the plug-and-play function, it is inconvenient to install manually.

In addition, many applications running on a computer must perform an installation process in which a program must be installed on the computer in order to execute the program.

This installation is done once on the user's computer and no further installation is required, but for computers that do not have an application running by the user, the user has a CD-ROM or a specific storage medium to install the application. There is a problem that you need to carry or carry a portable computer such as a laptop with an application installed.

In addition, when the installed application is an expensive program, there is a problem in that the program must be deleted from the computer after the use of the program is terminated for security.

In addition, there is a problem of illegally using the application program by hacking the application program stored in the CD-ROM or a specific storage medium and the serial number or software security key of the application program.

Accordingly, in order to solve the above problems, the present invention provides a removable storage device in which a user can install a driving driver without a separate installation process by embedding a drive driver for driving a removable storage device for storing data in the removable storage device. It aims to do it.

In addition, another object of the present invention is to provide a removable storage device having a security function to limit the use of the removable storage device.

It is a flow chart showing. The driving method of the mobile storage device according to the present invention will be described with reference to FIGS. 3 to 6 as follows.

When the user connects the removable storage device 100 to the computer in order to execute an application stored in the removable storage device 100 on the computer, the operating system (OS) of the computer detects whether the new storage device is connected to the computer ( S100).

In operation S100, the operating system executes a driving driver of a storage device connected to a computer through plug and play, and detects current directory information in which the portable storage device 100 is installed (200).

The operating system detects a drive driver of the removable storage device 100 by searching for a drive driver for driving the removable storage device 100 connected to the computer from a driver database (not shown) of the computer (S220).

If the drive driver of the mobile storage device 100 connected to the computer is not installed in step S220, the operating system requests the driver information from the mobile storage device 100, and the control unit 120 of the mobile storage device 100 is an operating system. Drive driver installation information stored in the ROM 140 is transmitted to the computer at the request (S230).

The driver installation information transmitted in step S230 is automatically installed in the driver database (S240). In step S240, the installation information of the driving driver is loaded into the memory of the computer and the driving driver is sequentially installed in response to the plug and play required by the operating system. In operation S240, when the installation of the driver is completed, the operating system recognizes the removable storage device 100 connected to the computer and sets a directory of the removable storage device 100.

When a connection signal for driving the mobile storage device 100 is output from the operating system, the control unit 120 of the mobile storage device 100 determines whether it is an initial connection signal after power-up, and when it is the first connection, the flash memory 130. The password input program stored in the program is transmitted to the computer (S250) to detect the input of the password.

On the other hand, if the driver is installed in the driver database in step S220 and performs the step S250, if the first connection in the step S250 is not the transmission of the password input program does not occur.

When the password is input from the computer after performing the step S250, the controller 120 of the storage device 100 reads and compares the device encryption information stored in the ROM 140 to determine whether the correct password has been input (S260). do.

If an incorrect password is input in step S260, the process returns to step S250. If the correct password is input, the access is allowed to the computer and the current directory information of the removable storage device is received from the computer (S270). Store in

After performing the step S270, the controller 120 transmits the stored information stored in the flash memory 130 to the computer (S280).

After performing step S280, the controller 120 executes an application program to be driven by autorun (S300). The execution of the application program using the autorun in step S300 is performed as follows.

The controller 120 combines the directory information stored in the flash memory 130 and the autorun information stored in the ROM to generate an autorun file in which an execution path of an application file is set (S310), and the autorun file generated in step S310 is transferred to a computer. Transmission (S320).

The process of generating an autorun file in step S310 is as follows. For example, if the removable storage device connected to the computer is set to the 'E' drive and the executable file of the application to be executed as the autorun is msword.exe, the autorun.inf of the application stored in the ROM 140 is [autorun] open. It is set to = msword.exe. The controller 120 detects the directory information of the removable storage device installed in the computer, that is, the autorun information of the 'E' drive and the application program stored in the ROM 140, that is, the execution file information msword.exe of the application to be executed, and thus the execution path, that is, the root directory. If E: \ msword.exe is created by setting the and application, the operating system finds autorun.inf in the root directory of 'E' drive and executes the application by the autorun.inf script.

Meanwhile, the executable file for executing the application program includes an encryption key value.

After performing step S320, the controller 120 determines the execution of the application program from the computer (S330), and if the execution of the application program detects the encryption information stored in the ROM 140 (S340) to encrypt the executable file. The application program is executed by combining the key values (S350). If the encryption key values are not combined in step S350, the application program is not executed.

On the other hand, in step S330, if the application is not executed, for example, if a shift key is input to cancel the autorun, the execution of the application is stopped and information stored in the flash memory 130 is transmitted (S360). .

After the operation S350 is performed, data information of the flash memory 130 is updated (S400) according to an execution of the application program or a command of copying or deleting transmitted from an operating system.

As described above, the present invention enables the user to execute an application program stored in a removable storage device without a separate installation process, thereby improving user convenience.

In addition, the present invention has the advantage that can be executed only in the removable storage device to prevent expensive application duplication.

In addition, the present invention has an advantage that the data security function of the removable storage device is improved as a security function to limit the use of the removable storage device.

In addition, the present invention has the advantage that the user can install the drive driver without a separate installation process by embedding the drive driver for driving the mobile storage device for storing data in the mobile storage device.

In the above, the present invention has been shown and described with respect to certain preferred embodiments. However, the present invention is not limited only to the above-described embodiment, and those skilled in the art to which the present invention pertains without departing from the spirit of the technical idea of the present invention described in the following Utility Model Claims.
