According to another aspect of the present invention, there is provided a method for processing a multimedia content file containing text for copyright protection of text that can be supplied via a network. The content file processing method may include a text-image conversion step of generating a plurality of GIF files by converting a text file included in newly created or pre-stored multimedia content into a GIF format image file, and generating the text-image conversion step. A plurality of partial image files are processed by transparent GIF processing of a part of each image so that the images represented by the plurality of GIF files are not overlapped with each other, and when the images are combined, they are restored to the image represented by the original GIF file. Generating a partial image file; receiving a request for the content from the user terminal, if receiving the request; and receiving the user request, transferring the partial image files generated from the content to the user terminal. Includes a sending step to send The.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 1, FIG. 1 is a conceptual diagram for describing an outline of a content file processing system according to an embodiment of the present invention. As shown, the content file processing system 100 (hereinafter referred to simply as " system ") 100 of the present invention is connected to the Internet 200, and a content server for transmitting content requested by the terminal 300 to a personal terminal 300 connected to the Internet 200. It is preferable to include. The user terminal 300 may access a network 200 such as the Internet through a wireless network and / or a wired network, such as a personal computer 302, a personal mobile terminal 304, or a mobile phone 306, and access a specific web page to display its contents. It should be noted that any type of hardware and / or software that includes a browser can be included. Furthermore, the intermediate processing performed to access a particular web page and display its contents has no reason to specifically limit the manner and type thereof, and the contents thereof are already in the field including the technical idea of the present invention. Since it is widely known, the detail is abbreviate | omitted.

If content creators create new content using the User Created Contents (UCC) authoring tool provided by System 100 and store it in a database inside or outside of System 100, or if content creators or copyright holders store content already created in the database, The system 100 processes the content file for copyright protection of the content, and transmits a request for the content from the terminal 300 to the terminal 300 through the network 200. In the present invention, the content is composed of either or both of a still picture and text, where the still picture refers to a picture or picture without a time element. Moreover, those skilled in the art will clearly recognize that the still picture may include one still frame constituting a moving picture.

The content transmitted to the terminal 300 by the system 100 is displayed on the screen of the user terminal in its entirety, but only a small part of the content is cut, copy, and paste activated. In this way, it is possible to prevent copyright infringement caused by the user copying and pasting the entire content as it is or distributing it to other users.

2 is a block diagram conceptually illustrating a configuration of a content file processing system 100 according to an embodiment of the present invention. The system 100 includes a content separation module 102, a text-image conversion module 104, a partial image file generation module 106, a reception module 108, and a transmission module 110. In addition, the system 100 is essential to its operation, and may further include a known hardware 150 and software 152 such as an operating system. The modules are interconnected by a bus.

The content separation module 102 separates the newly created or registered content by the content copyright holder into an image file and a text file, respectively. The text-image conversion module 104 converts the text file separated from the content into an image file. The conversion format can be any image file format such as JPG, TIF, or GIF, but the double GIF format is most preferable. The reason is explained in more detail below with reference to FIG.

The partial image file generation module 106 generates a plurality of partial image files from an image file separated from the content and / or an image file converted from the text file. More specifically, the partial image file generation module 106 disassembles the image file separated from the content by the content separation module 102 and the image file converted by the text-image conversion module 104 into a plurality of image files. The plurality of partial image files generated by the partial image file generating module 106 may be restored to the original image when the images displayed by the image files do not overlap each other and are combined.

The receiving module 108 detects whether there is a request for content from the user terminal 300 and receives the request if there is a request. When the receiving module 108 receives the request from the terminal 300, the transmitting module 110 transmits the partial image files generated from the requested content to the user terminal 300.

Hereinafter, a process of processing a content file by the system 100 according to the present invention will be described in more detail with reference to FIGS. 3 to 5. 3A illustrates an example of content in which an image and text are combined, displayed through a web browser. The content separation module 102 separates the contents of FIG. 3A into an image file and a text file (FIGS. 3B and 3C). The text-image conversion module 104 converts the separated text file into an image file.

4 and 5, FIG. 4 (a) is an image represented by an image file separated from the content of FIG. 3 (a), and FIG. 5 (a) is separated from the content of FIG. 3 (a). And the image represented by the image file converted by text-image conversion module 104. 4 (b) to 4 (e) show that the image of FIG. 4 (a) is divided into four partial images by the partial image file generation module 106, and FIGS. 5 (b) and 5 ( c) shows a state in which the image of FIG. 5 (a) is separated into two partial images. As shown in FIGS. 4 and 5, the images represented by the partial image files do not overlap each other, and when the images are combined, the image represented by the original image file is restored.

In this example, the partial image file generation module 106 separates the image file of FIG. 4A into four rectangular partial image files (FIGS. 4B to 4E). When sending these four partial images to the user terminal 300, the user can use the partial images included in the top layer by controlling each image to be integrated and sent in a layer format or output in a layer format from the web browser of the terminal 300. It is desirable to. Thereby, the user can be prevented from copying and distributing the image included in the content.

Also, in this example, text-image conversion module 104 converts the text file into an image file in GIF format. The GIF file format has a function of making certain parts of an image appear transparent, that is, a transparent GIF function, and using this function can more effectively protect the text part of the content. The process of generating the partial image file of the partial image file generating module 106 of FIGS. 5B and 5C is as follows.

First, the partial image file generation module 106 copies two image files generated by the text-image conversion module 104 to generate two identical GIF files, one of which is shaped like a “ㅌ” in FIG. 5 (b). A part of the transparent GIF is processed and the result is stored as a first part image file, and the other is a transparent GIF processing of the part displayed in the image of Fig. 5 (b), whereby "ㅕ" shown in Fig. 5 (c) is shown. Create an image of the shape and save the result as a second partial image file. Thus, the first and second partial image files have no overlapping portions of the images, and when they are combined, the original image is restored.

In particular, as shown in Figure 5, by converting the text into an image file of the GIF format and utilizing the transparent GIF function, it is possible to split each character into two different files. In addition, if these files are included in different layers and transmitted to the terminal 300, the user can copy only the images included in the top layer, so that the user can copy or distribute all or part of the text as it is or modify the contents thereof. Distribution can be prevented. In addition, if the image is separated in the same manner as shown in Figs. 4 (b) to 4 (e), the number of partial image files is rapidly increased in order to divide each letter into two parts. The above effect can be achieved with only two partial image files. On the other hand, it can be understood that even from the original image file as shown in FIG. 4 (a), two or more partial image files can be generated through the transparent GIF function as described above. In this case, the partial image file generation module 106 generates a plurality of image files in a GIF format from the image file, and generates a plurality of partial image files by transparent GIF processing the plurality of GIF files.

As described above, if the text is converted into an image file and one image is divided into a plurality of partial images and provided to the terminal 300, copyright infringement caused by copying and pasting the image file or the text as it is can be prevented.

6 is a block diagram conceptually illustrating a configuration of a content file processing system according to another embodiment of the present invention. In FIG. 6, with respect to components having the same names as those illustrated in FIG. 2, that is, 602 to 610, 650, and 652, 102 to 110, 150, and 152 illustrated in FIG. And since the functions are the same or similar, descriptions except for those unique to this embodiment will be omitted below.

The content file processing system 600 of FIG. 6 includes a content separation module 602, a text-image conversion module 604, a partial image file generation module 606, a reception module 608, a transmission module 610, a storage module 612, and an authentication module 614. It further includes.

The storage module 612 attaches and stores a security key to each of the plurality of partial image files generated by the partial image file generation module 606. In the present embodiment, it is preferable to inquire whether a user who accesses the system 600 agrees to copyright protection of the content provided by the system 600, and assigns a security key only to the user who agrees to the content. The same security key may be used for each content or a separate one for each content. In addition, the security key of the partial image file and the security key of the user terminal may not be completely identical in form or content with each other, depending on the type of terminal and a communication protocol.

When the receiving module 608 receives the user's security key with the request for the content from the user terminal 300, the authentication module 614 confirms whether the received security key matches the security keys of the partial image files. As a result of the check, if the security key is not received from the user terminal 300 or does not match the security key for the partial image files, the system 600 does not transmit the content to the terminal 300. However, as a result of the check, if the security key from the user terminal 300 matches the security key for the partial image files, the system 600 transmits the content to the terminal 300.

In addition, as described above with reference to FIGS. 3 to 5, the transmission module 610 may integrate the partial image files in a layer format and transmit the partial image files to the user terminal 300. This can prevent the user from combining the partial images to recover and use the entire image.

In this way, the copyright of the content can be more reliably protected by attaching and storing the security key to the partial image file and performing authentication with the security key of the user who requested the content.

Meanwhile, as another embodiment, the system 600 may further include a control module 616 that controls the user terminal 300 to output partial image files of the received content in a layer format. In this case, the transmission module 610 transmits the partial image files to the user terminal 300 as it is. When the terminal 300 receives the partial image files, the control module controls the web browser of the terminal 300 to output the partial image files to different layers.

Next, FIG. 7 is a flowchart conceptually illustrating an operation of a content file processing system according to an embodiment of the present invention.

When the operation of the content file processing system is started (step 700), and the content creator creates new content or the content creator or copyright holder newly registers the content (step 702), the content file processing system informs the content creator or the copyright owner of the content. It is confirmed whether or not copyright protection processing is to be performed (step 704). According to the embodiment, it is also possible to perform the following copyright protection processing without such a confirmation procedure.

If the content creator or the copyright holder does not want copyright protection processing for the content (No: 704), the content is transmitted as it is if requested from the user terminal 300 (step 724). If a copyright protection process is requested (Yes: Yes), the content is separated into an image file and a text file (step 706).

Next, the content creator or copyright owner is asked to activate the ability to edit and modify the text later (step 708). If you wish to edit the text later (Yes: 708), the text file is encrypted and stored (step 726) so that only the content creator or copyright holder can edit the text file.

Next, the content creator or copyright owner is asked whether to set the resolution of the image file (step 710). If no resolution is desired (710: No), the text file is converted to an image file of the default resolution (step 728). If the resolution is set (710: Yes), the text file is converted into an image file of the set resolution (step 712). At this time, the format of the image file is preferably GIF.

Next, a plurality of partial image files are generated from the image file separated in step 706 and / or the image file converted in step 712 (step 714), and stored by attaching a security key to each of the partial image files (step 716). .

If there is a request for content from the user terminal (step 718), the content file processing system checks whether the security key of the partial image file matches the security key received from the user terminal (step 720). If the security key does not match (720: No), the operation of the content file processing system is terminated (step 730). If the security key matches (720: YES), the partial image file is integrated and transmitted (step 722). In step 722, it is desirable to transfer the partial image files in a layer format. Alternatively, the user terminal may be controlled to output the partial image file transmitted in step 722 in a layer format from the user terminal.

As mentioned above, although the technical idea of this invention was demonstrated in detail through the preferable embodiment of this invention, the said content is only one Embodiment of this invention, It should not be interpreted as limiting the scope of the present invention.

As is evident from the above, by converting the text contained in the online content into an image file, separating one image into a plurality of partial images and providing them to the user terminal, thereby copying and pasting the image file or text without the consent of the copyright holder. "Or by editing a portion thereof to prevent copyright infringement caused by distribution to other users.

In particular, by generating a partial image file of the image file converted from the text file to the GIF format by using the transparent GIF function, it is possible to fundamentally prevent copyright infringement of the text by "copying and pasting".

In addition, by attaching a security key to a partial image file generated from an image file or a text file included in the content, and performing an authentication operation for confirming with the security key of the user who requested the content, the copyright of the content can be more reliably protected. Can be.
