Description

File control system and method using user server

The present invention relates to a file control system and method using a user server, and more particularly, to a file control system and method using a user server that can reduce inconvenience and ensure scalability while complying with web standards and web security. will be.

The web standard technology is a method of transmitting data using HTTP or HTTPS protocol and is used in a general web browser. Such web standard technologies include HTML4 or HTML5, which was confirmed as a standard technology by the World Wide Web Consortium (W3C) at the end of 2014.

Recent web standard technologies are generally closely related to web security, and each web browser (such as Microsoft's Internet Explorer or Edge browser, Google's Chrome, Mozilla Foundation's Firefox, Opera's Opera, Apple's Safari, etc.) It is implemented by different technologies on its own.

Many web browsers that comply with web standards and web security handle file processing within the browser in their own sandboxed form. That is, a file selected by a user to transfer a file from a PC or device to a web server using a browser is generally protected by the browser such that random access is not possible.

Although the selected file is a file selected by the user, it cannot be directly executed or a corresponding path is known. Many web browsers provide information such as file name and file size of a selected file, but generally do not provide programmatically accessible information including file location information. For example, each browser, such as a fake path, is configured to provide a virtual location path and provide no direct access.

1 is a diagram illustrating a conventional bulletin board service. In detail, the web document created by the client terminal 110 is transmitted to the bulletin board server 120 and then the creator or a user allowed by the creator can access the Internet through the website provided by the bulletin board server 120.

In the conventional web environment, bulletin boards or e-mail services are mainly made of text, but due to the development of multimedia, the format of web contents is diversified and large in capacity. In particular, when sending attachments using a web browser, most web browsers comply with web standards and web security.

Therefore, if the author of the post attaches the selected file through attaching the file, the file is protected by the sandbox mechanism of each browser, and therefore the contents of the attached file cannot be confirmed even if the user wants to confirm the attached file before the final transmission. There is a problem.

As described above, most browsers complying with the web standards and web security cannot check after opening the important file in the browser before transmitting the important file to the server as described above. It does not provide extensibility in transferring files. Here, the extensibility is a method of transferring a file by using a java script, which is a scripting language provided by each browser, or by using a method other than a web standard transmission method such as a POST or PUT method. It refers to the transmission method using the plug-in of each browser.

Existing ActiveX or Plug-In delivery method of each browser can add programmatic elements more than web standard delivery method, so it has the advantage of quick delivery and various UI (User Interface) provision.

However, the web browser extension provided by each web browser has to be installed for each web browser like ActiveX of Internet Explorer (Microsoft). In recent years, the developer of each web browser has a browser extension. There is a trend towards providing a minimum of features.

Accordingly, a first object of the present invention is to solve a problem of an extension function of a web browser using a user server, and to provide an advantage of an extension function to a user of the web browser as much as possible without installing an external program such as an ActiveX or a plug-in. It is to provide a file control system that can be provided.

In addition, a second object of the present invention is to create a file selection dialog by using a user server instead of a web browser, and to select a file to extract the file information for the file to control the file protected by web security To provide a control method.

In order to achieve the first object of the present invention described above, in an embodiment of the present invention, in the file control system for transmitting a file stored in the client terminal of the user to the web server via a web browser, the client terminal is attached to the file; A search command is transmitted when a click signal for searching for a file is input, and a web browser for displaying a file name included in the file information in a file attachment box as file information is received, and a file selection dialog when the search command is received. Is displayed on a web browser, extracts file information of a selected file, and transmits the file information to a web browser.

In addition, in order to achieve the second object of the present invention, in an embodiment of the present invention, in the file control method for transmitting a file stored in the client terminal of the user to the web server via a web browser, the web browser is attached to the file A file selection request step of transmitting a search command to a user server when a click signal for searching for a file is input; a file explorer display step of generating a file selection dialog box displayed on the web browser by the user server; and selecting the user server. A file control method including a file information extraction step of extracting file information of a file and transmitting the file information to a web browser, and a file attachment step of displaying, by the web browser, a file name included in the file information in a file attachment box; Provide a method.

Using the file control system according to the present invention, the user can check the file in advance in a web browser before transmitting the important file to an external web server. Specifically, in the present invention, instead of the cumbersome method of downloading and checking the file from an external web server after uploading the file to an external web server using a web browser, a web browser is created through the user server by creating a user server on my computer. By using a method that handles file searching, file attachment, file transfer, etc., the time required to check a file is reduced and the cumbersome procedure is omitted compared to the conventional method.

In addition, the present invention can feel the transmission speed of several times more than the existing even if the file is transmitted through a web browser compliant with the web standards and web security.

In addition, the present invention can use the file encryption, file resizing, file conversion, and then the transfer function, even if you send a post (or file) through a web browser, even without installing an external program such as ActiveX or a plug-in in the web browser have.

Hereinafter, a file control system (hereinafter, referred to as a file control system) using a user server according to exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, a file control system according to the present invention includes a client terminal provided with a web server 110 and a user server managing file information of the file to control a file attached to the web browser 110. 100, and a web server connected to the client terminal 100 through a wired / wireless communication network (hereinafter, referred to as a “communication network”) to receive a file transmitted from the web browser 110 of the client terminal 100 ( 200).

Hereinafter, each component will be described in more detail with reference to the accompanying drawings.

Referring to FIG. 2, the file control system according to the present invention includes a client terminal 100.

The client terminal 100 executes a web browser 110 and attaches a file (or a post including a file) or a folder through the web browser 110 and then transmits the file or folder to the web server 200. By doing so, the user receives a file or folder to be attached to the web browser 110 and attaches the selected file or folder to the web browser 110.

The client terminal 100 receives a click signal of a file search for attaching a file to the web browser 110 from the user. In addition, the client terminal 100 receives an execution command for the execution of the file attached to the web browser 110 from the user. In addition, the client terminal 100 receives an upload command for uploading a file attached to the web browser 110 from a user.

To this end, the client terminal 100 includes a user interface unit (not shown), a web browser 110, and a user server 120.

In detail, the user interface unit is connected to an external web server 200 and displays a web browser 110 to which a file is to be attached as shown in FIG. 3. In addition, the user interface unit receives a click signal for any one of the plurality of files attached to the file attachment box and provides a function of displaying the check signal in the web browser 110 of FIG. 3.

In addition, when a plurality of files are uploaded as shown in FIG. 3, the user interface unit analyzes a check signal of an attached file collected by the web browser 110 according to an input of a double click signal among the files attached to the file attachment box. Select the file from which the check signal was collected. In other words, when a user interface unit receives a double click signal for a file attached to the web browser 110, the user interface unit generates an execution command for the file and provides it to the web browser 110.

The web browser 100 transmits a search command to the user server 120 as a click signal of a file search for file attachment is input as shown in FIG. 4, and as file information is received from the user server 120, file information. Display the file name contained in the file attachment box.

For example, when a click signal for a 'file search' button is received as shown in FIG. 3, the web browser 110 generates a search command and transmits the search command to the user server 120. The general web browser 110 provides a function of searching for a file to be selected by a user by executing a file selection dialog (file explorer) when a click signal for a 'file search' button is received, but the present invention provides a web browser 110. Instead, the user server 120 executes the file selection dialog.

In addition, the web browser 110 provides a function of attaching the file information to the file attachment box after receiving the file information transmitted from the user server 120. In this case, the file attached to the file attachment box is protected by a sandbox, which is a security software that operates the program within the protected area. Therefore, the file attached to the file attachment box of a typical web browser is executed even if the user double-clicks it. This doesn't work. In other words, the sandbox restricts access to the system resources of the applet sent over the network, so you cannot see the files attached to the file attachment box on a typical web browser.

On the contrary, when the execution command for the file attached to the file attachment box of the web browser is input (click of the file open button) as shown in FIG. 5, the web browser 110 according to the present invention executes the user server to execute the file. The processor 120 transmits one of file information and a mapping key of the file and an execution command. At this time, if the file open button is not provided in the web browser 110, the web browser 110 doubles the user server 120 when a double click signal of a file attached to the file attachment box is input through the user interface unit. The execution signal is transmitted to one of the file information and the mapping key of the file to which the click signal is input.

In addition, when the upload command for the file attached to the file attachment box of the web browser 110 is input, as shown in FIG. 6, the web browser 110 uploads the file to the web server. Send file information and upload command.

On the other hand, the user server 120 constituting the client terminal 100 according to the present invention is installed in the client terminal 100 and connected to the web browser 110 in a configuration for transmitting and receiving information with the web browser 110, A user server processor 121 and a file controller 126 are included.

When the user server 120, for example, the user server processor 121 receives a search command from the web browser 110 as shown in FIG. 4, displays the file selection dialog in the web browser 110 and is selected through the file selection dialog. Extracts file information of a file and transmits the file information to the web browser 110. In this case, the file information includes a file name and a file storage path, and may optionally further include a file size and a file extension.

As an embodiment, the user server 120, for example, the user server processor 121 according to the present invention may be configured to transmit the file information to the web browser 110 without storing the file information itself.

In another embodiment, the user server 120 according to the present invention, for example, the user server processor 121 stores the file information extracted from the file, generates and stores a mapping key mapped to the file information, the file File information and a mapping key excluding a storage path may be configured to be transmitted to the web browser 110. In this case, the user server processor 121 stores the file information and the mapping key in a storage module (not shown) provided in the self.

When the user server 120, for example, the user server processor 121 receives an execution command and file information from the web browser 110 as shown in FIG. 5, searches for and executes a file through a file storage path included in the file information. Let's do it.

In addition, when a mapping key is received from the web browser 110, for example, the user server 120, for example, the user server processor 121 searches for and executes a file through a file storage path included in file information matched with the mapping key. . More specifically, when the mapping key is transmitted from the web browser 110 instead of the file information, the user server 120 extracts the file information corresponding to the mapping key from the storage module, and the file storage path included in the file information. Search for the file and execute it.

When the upload command and the file information are received from the web browser 110 as illustrated in FIG. 6, the user server 120 searches for a file through a file storage path included in the file information, and the file is stored in the web server 200. To send.

More specifically, when the upload command and the file information are received from the web browser 110, the user server processor 121 searches for a file through a file storage path included in the file information, and the file controller 126. To provide.

The file controller 126 also transmits the file to a web server via a communication network. In this case, the file control unit 126 may provide any one or more of a function to be subsequently transmitted, an encryption function, a resizing function, and a file conversion function for the file to be transmitted to the web server 200. The file controller 126 may provide an ActiveX function installed in Internet Explorer (IE) or a plug-in function installed in Chrome. For example, when the file controller 126 transmits a file to the web server 200 through the user server 120 instead of the web browser 110, the file controller 126 may provide a function of continuously transmitting the disconnected file even if a file break occurs. do.

As described above, the existing web browser can provide a special function only by installing a program such as ActiveX or a plug-in. However, the present invention does not install the ActiveX or plug-in to the web browser 110. Can be provided.

In addition, the user server 120 may be configured to display the transmission result of the file uploaded to the web server 200 in the web browser 110. Specifically, when the response information (Response) is received from the web server 200, the file controller 126 displays the response information (Response) for the transmission result in the web browser 110.

As such, the user server processor 121 may check the contents of the file on the web browser 110 before the client terminal 100 uploads the file to the web server 200 through the web browser 110. Provides a function to execute the file by receiving the file information or the mapping key from the browser (110).

In other words, in the past, when a user wants to check the contents of a file attached to the web browser 110, both upload and download processes of downloading the file from the external server after uploading the file to the external server are necessary. According to the present invention, since the user server 120 communicating with the web browser 110 is built in the client terminal 100 owned by the user, the file can be checked without upload or download process. In other words, the present invention reduces the time it takes to check the file compared to the conventional one, and the cumbersome procedure is omitted.

Meanwhile, the client terminal 100 provides the HTML file of the web browser 110 through a wireless communication network including a plurality of base stations, a base station controller, a mobile communication switch, and a WAP gateway, and a wired communication network such as the Internet. Means means for connecting to the web server 200, and can use a wireless terminal and a wired terminal.

In this case, a wireless terminal may be a smart phone, a tablet PC, a notebook computer and the like, and as a wired terminal, a personal computer having a means for accessing the Internet, a smart TV, or the like may be used.

Referring to FIG. 2, the file control system according to the present invention includes a web server 200.

The web server 200 is a server that provides users with a file containing a web page such as an HTML document using HTTP of the web, and is connected to the client terminal 100 through a communication network.

When the web server 200 requests a file transfer from the connected client terminal 100 as shown in FIG. 2, the web server 200 responds with the result.

In addition, when the web server 200 receives a request for information on a bulletin board service from the connected client terminal 100, the web server 200 provides a web page for the bulletin board to the client terminal 100. The web server 200 provides a function of receiving and storing a post to which a file is attached from the client terminal 100.

For example, the web server 200 according to the present invention manages the processing unit 210 that performs the file upload and download function of the file control system, and manages the access rights of files for each user and adjusts the use access rights according to the rights for each user. A rights management unit that performs a function, a file management unit that manages files in the uploaded personal storage database and indexes and manages a physical storage space, and receives a specific control command from the client terminal 100 and responds thereto. It may include a command management unit for transmitting.

As a specific aspect, the web server 200 according to the present invention may be used a bulletin board web server. The bulletin board web server transmits various types of post-related web pages, such as viewing a post list, reading a post, and writing a post, to the client terminal 100 according to a user's request, and the web browser 110 of the client terminal 100 Display the web page sent from the bulletin board web server.

Since the web server 200 is a known configuration, more detailed description thereof will be omitted.
