Description

  The present invention relates to a content management method and a mobile communication terminal device, and more particularly, to a content management method for managing content included in an email exchanged between mobile communication terminal devices, and the content management method. The present invention relates to a mobile communication terminal device.

  2. Description of the Related Art Conventionally, mobile communication terminal devices represented by mobile phone devices have been widely used. The technology related to such mobile communication terminal devices has been remarkably advanced. For example, a cellular phone device or the like having an e-mail function was initially capable of only transmitting text information, but is now capable of transmitting image information such as photographs (Multimedia Messaging Service: MMS). Is also available.

  As an example in which text information and image information can be transmitted using such MMS, a method of transmitting a text file storing text information and an image file storing image information by a transmitting mobile phone or the like has been proposed. (See Patent Document 1). As described above, the text file and the image file are transmitted in two types of files. The text format cannot express image information. In the image format, simple text characters in the text format (code) are transmitted. This is because the advantage of expression is lost.

  By the way, a message transmitted by mail is generally a copyrighted work, and is protected by copyright. When such a message is only text information, it cannot be said that the copyrighted property of the message is high, and the need for protection by copyright is low because it is not highly usable by others.

  However, as the transmission / reception of mails using MMS has become widespread, messages that are transmitted contain content that is highly copyrightable and highly usable by others. In order to protect such contents, it is conceivable to adopt a so-called forward-lock method in which copyright management information for restricting storage for reuse is included in an email.

  Content protection by such copyright management information is generally performed using a file as a minimum unit. For this reason, when a message including text information and image information is transmitted by mail using MMS, the object to be protected by the copyright management information is the text information included in the text file, the image information included in the image file, or the message. It becomes the whole.

JP 2005-182324 A

  By the way, the message transmitted using the MMS described above may include a new content created using a plurality of contents each of which is a copyrighted work as one file. For example, a case where a new image created by combining a plurality of images is made into one file corresponds to this case.

  On the side of receiving a message in which new content created by using such a plurality of contents is made into one file, reuse is restricted among the plurality of contents used to create the received message. If there are none, it is desirable to be able to use them when composing new messages. However, for example, when a new image created by combining a plurality of images is a single file, it is only the new image if it can be reused.

  In addition, when there is at least one content whose reuse is restricted among a plurality of contents used to create a new content that is a single file, the use of the new content is also restricted. It will be. This means that the new content corresponds to a secondary work whose original work is a content whose reuse is restricted.

  Furthermore, even if a plurality of contents used for creating new contents that are made into one file can be individually disassembled, the protection of the contents by the current copyright management information is performed with the file as a minimum unit. For this reason, if at least one content whose reuse is restricted is included, the reuse of all the content must be restricted. This is to prevent the reuse of a copyrighted work whose reuse is restricted.

  The present invention has been made in view of the above circumstances, and a content management method capable of finely managing the use of each content while respecting the protection by the copyright assigned to each content included in an email. The purpose is to provide.

  [Operation]

  Next, SVGM mail transmission / reception processing in the mobile communication system 100 configured as described above will be described. The following description will be given by taking as an example the case where the SVGM mail created by the mobile phone device 10 is transmitted to the mobile phone device 20.

  When the user of the mobile phone device 10 transmits an SVGM mail to the mobile phone device 20, as shown in FIG. 8, first, in step S11, the transmission SVGM mail processing unit 71 of the mobile phone device 10 Create an SVGM message. In step S11, the transmission SVGM mail processing unit 71 creates the SVGM message 60 by creating the SVGM file 61 and the control file 62 while referring to the screen component set 26 in the storage unit 23 as appropriate.

  When the SVGM file 61 is created, the transmission SVGM mail processing unit 71 first determines the type of screen component designated to be included in the SVGM message transmitted to the mobile phone device 20 by the user of the mobile communication system 100. . If the screen component specified by the user is a text character as a result of this determination, the transmission SVGM mail processing unit 71 performs a process for inserting a line feed as appropriate, and for each unit specified by the user. Decorate fonts, display colors, etc. specified based on the user's taste. Then, the transmission SVGM mail processing unit 71 describes the copyright management information designated by the user according to the mobile phone device 20 that is the transmission destination. In this way, a screen component of text characters is created. Then, the transmission SVGM mail processing unit 71 stores the created screen component in the SVGM file 61.

  If the screen component designated by the user is in the screen component set 26, the transmission SVGM mail processing unit 71 determines that the copyright of the designated screen component is the mobile phone device 10. It is determined whether or not the user is present. If this determination is negative, the transmission SVGM mail processing unit 71 determines whether transfer is restricted in the copyright management information in the screen component. If the determination result regarding the transfer restriction is affirmative, the transmission SVGM mail processing unit 71 uses a message such as displaying on the display unit 13 that the screen component cannot be used to create a transmission message. The person in charge. On the other hand, if the determination result regarding the transfer restriction is affirmative, the transmission SVGM mail processing unit 71 stores the screen component in the SVGM file 61. It should be noted that the background color is designated when the screen component is created.

  If the determination result regarding the possession of the copyright is affirmative, the transmission SVGM mail processing unit 71 receives the copyright management information designated according to the mobile phone device 20 in response to a command from the user. Describe in the copyright management information description section. Thereafter, the transmission SVGM mail processing unit 71 stores the screen component in the SVGM file 61.

  By creating the screen component and storing it in the SVGM file 61, the SVGM file 61 corresponding to the SVGM message 60 to be transmitted is created.

  Further, the transmission SVGM mail processing unit 71 creates the control file 62 in accordance with a command input from the operation unit 12 by the user. When creating the control file 62, the transmission SVGM mail processing unit 71 creates the control file 62 so that the screen components in the created SVGM file 61 are appropriately displayed on the screen.

  When the SVGM message 60 is created as described above, the transmission SVGM mail processing unit 71 of the mobile phone device 10 transmits the SVGM mail including the SVGM message 60 in step S12. When this SVGM mail is transmitted, the transmission SVGM mail processing unit 71 creates an SVGM mail in which the destination (cell phone device 20) designated by the user, the title, and the like are added to the SVGM message 60. When a transmission command is issued from the user, the transmission SVGM mail processing unit 71 transmits the SVGM mail to the mobile phone device 20.

  The SVGM mail thus transmitted from the mobile phone device 10 is received by the mobile phone device 20 in step S13. Thus, when the SVGM mail is received, the mobile phone device 20 notifies the user of the mobile phone device 20 that the mail has been received. In response to the received message display command from the user who has received this notification, the message display process in step S14 is performed.

  In the message display process of step S14, the received SVGM mail processing unit 72 of the mobile phone device 20 first determines whether or not the received message is the SVGM message 60. If the result of this determination is negative, the received SVGM mail processing unit 72 entrusts message display processing to a program module for performing message processing in another format. Hereinafter, the description will be made on the assumption that the result of the determination as to whether or not the received message is the SVGM message 60 is positive.

  When the received message is the SVGM message 60, the received SVGM mail processing unit 72 decodes the contents of the control file 62 and displays the screen components included in the SVGM file 61 in the display mode specified by the control file 62. Is displayed. Specifically, the received SVGM mail processing unit 72 (i) inserts a screen component of the inline image at a designated position in the character string, (ii) adjusts the display magnification to enlarge or enlarge each screen component. The screen components included in the SVGM file 61 are displayed by performing reduction or the like.

  When the above SVGM message display processing is completed, the received SVGM mail processing unit 72 reports the type of the screen component in the received SVGM message 60 to the screen component processing unit 73. Upon receiving this report, the screen component processing unit 73 performs a storage process for re-use regarding the screen components in the SVGM message 60 in step S15.

  In step S <b> 15, first, the screen component processing unit 73 determines whether or not each screen component in the SVGM message 60 is the same as that already stored in the screen component set 26. If the result of this determination is affirmative for all screen components in the SVGM message 60, the screen component processing unit 73 ends the process of step S15.

  On the other hand, if there is a negative result of the determination as to whether or not the same as the one stored in the screen component set 26, the screen component processing unit 73 displays those screen components. For each, it is determined whether storage for reuse is restricted. For a screen component having a positive determination result, the screen component processing unit 73 does not save for reuse. On the other hand, when the result of the determination regarding the limitation on the storage for reuse is negative, the screen component processing unit 73 determines the screen components that can be stored for reuse. Then, the user of the mobile phone device 20 is inquired whether or not to save for reuse.
