The present invention relates to an integrated viewer. More specifically, the present invention supports a user to view and edit desired data even when the user does not have an application for creating data for files of various formats. The present invention relates to a system and a method for providing a file manager to control reading and distribution of the file.

With the rapid growth of computer functions, various document creation programs exist, and documents are created using a favorite editing program for each user, and thus, various types of document formats exist according to various editing programs.

Currently, many files are exchanged in various ways, such as Internet download, file transfer via instant messenger, file download using peer-to-peer (P2P) method, and file attachment of E-mail. However, the downloaded file may be a file format that you do not know well, a file format of an application that is not installed on your computer even if you know it, or a file format of a version different from the installed application. Sometimes it can't be done, in which case you can't view or edit the file.

If the file cannot be opened as described above, the user must purchase the corresponding application or retransmit to the computer where the application is installed to view or edit the file.

On the other hand, since many files are exchanged as they are on the Internet, they may be disseminated or modified externally regardless of the intention of the file creator or administrator, and thus, privacy or content protection cannot be guaranteed.

In order to solve the above problems, development of an integrated viewer capable of integrating and reading various document formats has been made. However, in order to interpret the format structure in a conventional manner, the format of the editing program manufacturer must be premised. It can only be used for files in the in-scope, and if an existing program is to be upgraded, it must be reprogrammed. Therefore, there is a limitation in generality and cannot provide control over the file.

As another solution, a program for viewing a specific format (for example, Acrobat) even if the file creator or administrator converts a document file of various formats into a PDF (adobe) format, which is a widely used format in advance. reader) must be downloaded and installed separately. In addition, in case of CSD (Dream To Reality) format with a built-in viewer, it is cumbersome to perform pre-conversion work like PDF format, and separate storage space is required because the original file and the conversion result file must be stored and managed. Do. In addition, it partially supports simple reading control on a file basis, but fails to provide user-specific control means because it does not provide distribution control.

As described above, there has been a problem in that file security and content protection are impossible because there is no method for easily providing a means of reading control or distribution control for each user authority or file.

An object of the present invention for solving the above problems is to provide a file conversion server that provides a service for converting files, so that the administrator can set the reading or distribution control by document or subscriber service class by the administrator, the user When requesting the document, the document is transferred from the file server to the file conversion server, the file is converted, and then provided to the user terminal to control the document by the administrator.

As described above, a service provider server having a file of various formats, a file server for converting a file, and a user using a web browser 101 of the user terminal 100 while the user's computer is interconnected by a network. To receive the necessary information from the file DB 203 of the service provider server 200 and to edit a document using the file, an application program corresponding to the file obtained from the file DB 203 is mounted on the computer. Check if it is If the application is installed, it can be executed to edit the document.

However, if an application program corresponding to a file obtained from the file DB 203 is not installed in the computer, a file conversion service is provided to the file conversion server 300 so that the file conversion server 300 is provided in a form capable of viewing and editing the file. You will be asked.

When the file conversion server 300 receives a file conversion request from the user terminal 100, the file service program 301 is operated. Accordingly, the file conversion server 300 transfers the received file to the file conversion unit 302 to convert the file. In this case, the file converter 302 extracts the file in units of pages and transfers the file to the divider 304 to be divided into text and an image. The divider 304 divides the received file into text and an image and delivers the received file to the cache 303.

When the file is transmitted from the cache 303, which stores the document divided into page units and text and image, to the user terminal 100, the user is provided with the text as an image and an image, so that the text file is a preferred text editing program. Can be edited using.

The operation of the present invention configured as described above will be described.

2 is a flowchart illustrating an embodiment of a file conversion service request according to execution of an Active X program in a user terminal. As shown, when a user receives a file from an arbitrary web server and opens the file (S101), when an application program for the file is installed, the application program for the file is automatically executed. However, if an application program for the file is not installed, a conversion request is made to the file conversion server 300 to convert the file (S102).

A user identifier (UID) is received from the file conversion server 300 together with information on whether or not conversion is possible (S103), and data about whether or not conversion is included in the user identifier is determined (S104).

If it is determined in S104 that the file cannot be converted by the file conversion server, the user displays a file open disable message.

If it is determined in S104 that the file can be converted in the file conversion server, it must be determined from where the file is located (S105).

When the file is in the user terminal, the file is transmitted to the file conversion server 300, and when the file is in the server, the file is directly converted without the need to transmit the file (S107).

It is determined whether a document editing program for editing the converted file is present in the user terminal (S108), and if it is determined that there is no program, the program is downloaded and installed (S109). S110) Edit the document.

An operation description of the document editing will be described with reference to FIG. 3.

When a file change request is received from an arbitrary user (301), it is determined whether the requested file can be converted by the file conversion server (S302).

If the format of the file is not clear, or the user is not subscribed to the service or the file cannot be converted for various reasons, a message is transmitted to the user terminal 100 together with the user identifier (S311 and S312).

If it is determined in S302 that file conversion is possible, a message about this is transmitted to the user terminal 100 together with the user identifier (S303) and the cache table is checked to check whether the corresponding file is in the cache (S304).

If it is determined that there is a cache having the file in the cache table, the cache holding the file is called (S307) to execute the file conversion unit 302 (S308).

If it is determined that there is no cache with the file in the cache table, the cache load of each server is checked (S305) and the server with the minimum load is called (S306) to execute the file conversion unit 302 (S308).

The operation of the file converter 302 will be described with reference to FIG. 5.

5 is a flowchart illustrating an embodiment of a method of converting a file in a file conversion unit of a file conversion server.

First, the file conversion unit 302 searches through the queue whether there is a file with a conversion request (S411), and selects a spooling function according to whether or not a multi-process is executed (S412).

If it is determined that the multi-process is not running, the application program for spooling data is executed (S413). Thereafter, the file is spooled by the application program (S414) and when the spooling is completed, the spooled file is read (S415).

It is determined whether the spooling is completed to the end of the page (S416), and extracted for each page and transmitted to the division unit 304 to divide the page into text and image (S417).

When it is determined that the image is preferably reduced in relation to capacity, and the image reduction process (S418) is completed, the data of the page unit is stored in the cache (S419).

If it is confirmed that the end of the file is completed (S420), the operation is terminated until another file conversion request is made.

By the above processes, the user can receive the converted file from the file conversion server 300.

Although omitted from the above operation description, when the editing function is given by the administrator, a process of proving that the user is authenticated using the user's certificate may be additionally performed.

In addition, when an authenticated user wants to transfer or save the document after editing the document, a lock function may be used for the document. For important documents, the user can lock the document.
