<Processing executed in content processing system>
Next, various processes executed by the content processing system 100 will be described.

<Membership registration processing and content processing program distribution processing>
FIG. 4 shows the flow of member registration processing and content processing program distribution processing. In step S01, the control device 10 of the server accepts user membership registration. Specifically, when a predetermined address is input to the terminal device 3, the terminal device 3 accesses the server 1, and a member registration screen is displayed on the display device 31 of the terminal device. FIG. 5 shows an example of the member registration screen. On the member registration screen, an ID input area, a password input area, an address input area, a name input area, an e-mail address input area, a telephone number input area, and a decision button are displayed. When information such as an ID and a password is input through the input device 32 of the terminal device and the determination button is selected, the control device 30 of the terminal device sends the member registration information to the ID and password via the communication device 34 of the terminal device. Send to server 1. The control device 30 of the server 1 acquires member registration information via the communication device 14 of the server. If member registration information is received, it will progress to step S02.

  In step S02, the server control device 10 issues an ID and a password. Specifically, the server control device 10 checks whether there is a registered ID and password in the user database in the storage device 13 of the server. If there is no registered ID and password, the ID and password are stored in the user database. sign up. If there is a registered ID and password, the terminal device 3 is notified accordingly. FIG. 6 shows an example of a user database. In the user database, ID, password, address, name, e-mail address, telephone number, etc. are recorded for each user. When the ID and password are issued, the process proceeds to step S03.

  In step S03, the server control device 10 generates an internal ID. The internal ID is unique identification information associated with the ID issued in step S02. The internal ID is automatically issued by the server control device 10 and is unique identification information that cannot be visually recognized by the user. When the internal ID is generated, the process proceeds to step S04.

In step S04, the server control device 10 generates a content processing program. The content processing program is a program for editing distribution data to which editing authority is given. An internal ID is assigned to the editing authority. The content processing program becomes available when the user downloads it to the terminal device 3. In other words, the user downloads the content processing program to the terminal device 3 so that the terminal device 3
The acquired distribution data can be freely edited. Details of the editing process executed by the terminal device 3 will be described later. When the content processing program is generated, the process proceeds to step S05.

  In step S05, the server control device 10 distributes the content processing program to the terminal device 3 of the user who has registered as a member. That is, a content processing program having an internal ID is transmitted to the terminal device 3 via the communication device 14 of the server. The terminal device 3 receives the content processing program via the communication device 34 of the terminal device and stores it in a predetermined area of the storage device 33 or the memory 302. The server control device 10 also transmits the ID and password to the terminal device 3. The ID and password may be transmitted at the same timing as the content processing program or at a different timing. When the user has a plurality of terminal devices 3, the user acquires a content processing program for each terminal device 3. This completes the member registration process and the distribution process of the content processing program.

<Content acquisition processing>
Next, content acquisition (purchase) processing will be described. FIG. 7 shows a flow of content acquisition processing. Content acquisition can be performed through a content processing program, or can be performed by directly logging into the server 1.

  In step S11, the server control device 10 accepts an ID and a password as login information. Specifically, when a predetermined address is input to the terminal device 3 or the content processing program is started, a login screen is displayed on the display device 31 of the terminal device. FIG. 8A shows an example of a login screen. On the login screen, an input area for an ID and a password is provided. When the ID and password are input via the input device 32 of the terminal device, the server control device 10 authenticates the ID and password. If the ID and password are correct, the server control device 10 displays the top screen on the display device 31 of the terminal device. FIG. 8B shows an example of the top screen. On the top screen, a new purchase button for transitioning to a page for purchasing content and a purchase history button for transitioning to a page for displaying purchase history are displayed. On the other hand, if the ID and password are not correct, the server control device 10 displays a message such as “There is an error in the ID or password” on the display device 31 of the terminal device. When the login is completed, the process proceeds to step S12.

  In step S12, the control device 10 of the server accepts purchase of content. Specifically, when the new purchase button is selected on the top screen, the server control device 10 displays a content purchase screen on the display device 31 of the terminal device, and requests content purchase from the user (request for content data acquisition). ). FIG. 9 shows an example of a content purchase screen. On the content purchase screen, content recorded in the content database for each genre is displayed in addition to a search area for searching for content by inputting a keyword. Further, PDF, EPUB, and XMDF are displayed as output formats on the content purchase screen. The output format of FIG. 9 is an example, and is not limited to these. Furthermore, on the content purchase screen, a mobile phone, a smartphone, and a PC are displayed as distribution destination terminal devices. These are merely examples, and the distribution destination terminal device may display in more detail for each model. In FIG. 9, “History” is selected as the genre, “Content B” is selected from “History”, and “PDF” is selected as the output format. A mobile phone is selected as the distribution destination terminal device. FIG. 10 shows an example of a content database. The content database includes items of file name, genre, registration date / time, update date / time, and right holder, and stores information necessary for each item. When the content is selected, the process proceeds to step S13.

  In step S13, the control device 10 of the server registers the purchase history of the content in the purchase history database. Here, FIG. 11 shows an example of a purchase history database. The purchase history database is stored in the storage device 13 of the server. In the purchase history database, items of purchase user name, purchase content file name, purchase date / time, and edit date / time are provided, and necessary information is stored in each item. Yes. When the registration of the purchase history is completed, the process proceeds to step S14.

  In step S14, the server control device 10 generates distribution data to be distributed. Specifically, the server control device 10 accesses the content database, and the content requested by the user, in other words, the content data selected on the content purchase screen (corresponding to the distribution data of the present invention, for example, , Content B). Next, the server control device 10 changes the output format of the acquired content data as necessary, further incorporates the internal ID generated in the member registration process, and converts the ID into the content data so that the ID can be visually recognized. To generate data for distribution. The output format is a format selected by the user on the content purchase screen, and is “PDF” in the example of FIG. Incorporating the internal ID means setting the internal ID as management authority for the content data. As a result, the distribution data can be edited only by a content processing program in which a similar internal ID is incorporated. That is, the distribution data can be edited by the terminal device 3 that has acquired (downloaded) the content processing program.

  12A to 12D show examples of distribution data to which IDs are attached. 12A is an example of distribution data with an ID added to the header, FIG. 12B is an example of distribution data with an ID added to the footer, and FIG. 12C has multiple pages of distribution data. In this case, an example of distribution data in which IDs are attached to the footers of all pages is shown. FIG. 12D shows an example of distribution data in which an ID is attached only to the last page when there are a plurality of pages of distribution data. The area to which the ID is attached is not limited to the above as long as it is a place where the display of the content hardly affects the display of the content. The area to which the ID is attached may be attached to other margins or may be attached to the interior. The ID may be a digital watermark. It should be noted that the method and area for attaching the ID may be defined and changed by the user. When the distribution data to be distributed is generated, the process proceeds to step S15.

  In step S15, the generated distribution data is converted into the format of the terminal device 3 that is the distribution destination. Specifically, the server control device 10 converts the generated distribution data into a format of a distribution destination terminal device designated by the user (a mobile phone in the example of FIG. 9). When the conversion of the distribution data is completed, the process proceeds to step S16, and the converted distribution data is distributed. The content acquisition (purchase) process is thus completed.

  As described above, the distribution destination (download destination) terminal device 3 can browse the distribution data. Moreover, ID is attached | subjected to content data as the data for delivery delivered, and ID can be visually recognized. Accordingly, it is possible to track the duplicator when the content data is illegally copied beyond the range of private use. As a result, unauthorized duplication and distribution of content data can be suppressed. Further, since the content data is converted into a format corresponding to the terminal device of the distribution destination, the user can browse the content data in a format corresponding to the terminal device with a plurality of terminal devices owned by the user.

<Content data editing process>
Next, content data editing processing for editing distributed distribution data using a content processing program will be described. FIG. 13 shows a content data editing process flow. In the following description, a case where the distribution data is edited using the content processing program downloaded to the terminal device 3 will be described as an example. However, the distribution data editing process is performed by accessing the server 1 Can also be done.

  In step S21, in step S21, the control device 30 of the terminal device accepts an ID and a password as login information. Specifically, when a content data processing program already downloaded in the terminal device 3 is activated, a login screen is displayed on the display device 31 of the terminal device. For example, the login screen may have the same configuration as the login screen shown in FIG. When the ID and password are input via the input device 32 of the terminal device, the control device 30 of the terminal device authenticates the ID and password. When the ID and password are correct, the control device 30 of the terminal device displays the top screen on the display device 31 of the terminal device. FIG. 14 shows an example of the top screen. On the top screen, a new purchase button for transitioning to a page for purchasing content and a purchase history button for transitioning to a page for displaying purchase history are displayed. On the other hand, when the ID and password are not correct, the control device 30 of the terminal device displays a message such as “There is an error in the ID or password” on the display device 31 of the terminal device. When the login is completed, the process proceeds to step S22.

  In step S22, the control device 30 of the terminal device accepts an instruction to edit distribution data. Specifically, when the purchase history button is selected on the top screen, the control device 30 of the terminal device causes the display device 31 of the terminal device to display a distribution data editing processing screen (hereinafter also referred to as an editing processing screen). An editing instruction for distribution data from the user is accepted. FIG. 14 shows an example of the editing process screen. On the edit processing screen, a list of purchased distribution data and an edit type button are displayed. Examples of editing types include output format conversion, printing, clipping, color change, language conversion, and free editing, and buttons corresponding to these editing types are displayed on the editing processing screen. In the purchased distribution data list, a list of already purchased distribution data is displayed. In the conversion of the output format, it is possible to convert to an output format different from that at the time of purchase. For example, output format conversion includes conversion from PDF to EPUB, conversion from a mobile phone to a PC, and the like. In printing, distribution data can be printed. In the cutout, an arbitrary area can be cut out from the distribution data. In the color change, the content color can be changed. In the language change, the content can be changed to the language designated by the user. In free editing, other text such as text, images, and audio can be added and freely customized. When the distribution data editing instruction is accepted, the process proceeds to step S23.

  In step S23, the control device 30 of the terminal device executes editing. Here, FIG. 15 shows an example of the state of clipping in editing the distribution data. First, the control device 30 of the terminal device accepts designation of a region to be clipped via the input device 32 of the terminal device (left diagram in FIG. 15). Next, the control device 30 of the terminal device pastes the clipped area to another file (middle diagram in FIG. 15). Next, the control device 30 of the terminal device attaches an ID to the footer of another file to which the clipped region is pasted (the right diagram in FIG. 15). In the case of clipping, since the ID is originally attached to an area other than the area where the content is displayed, such as a header or a footer, the ID is not attached to the clipped content. Therefore, the control device 30 of the terminal device determines whether or not an ID is added to the edited distribution data. If not, the ID is re-added to the edited distribution data. As a result, it is possible to freely edit the distribution data and to suppress unauthorized duplication and distribution of the distribution data after editing. Thus, the editing process is completed.

<Effect>
According to the content processing system according to the embodiment described above, ID as identification information for each user is attached to content data as distribution data to be distributed, and the ID is always visible. Accordingly, it is possible to trace the copy person when the content is illegally copied beyond the range of private use. As a result, unauthorized duplication and distribution of content data can be suppressed. In addition, since the content data is converted into a format corresponding to the terminal device and distributed, the user can view the content data in a format corresponding to the terminal device with a plurality of terminal devices owned by the user. In the content processing system according to the embodiment, the user can easily edit the content data. FIG. 16 shows a functional comparison for content data.
