  Currently, file server devices that communicate with mobile data terminals such as mobile phone terminals are used in various businesses. In that case, the device which prevents unauthorized use of the digital content data which a file server apparatus provides to a portable data terminal is devised.

  For example, such a file server device stores digital content data including editable free text data. The stored digital content data is converted into a digital content image such as JPEG (Joint Photographic Coding Experts Group) that cannot be edited by the portable data terminal. The converted digital content image is held for each digital content data.

  In such a state, for example, when the file server apparatus receives a data browsing request for digital content data from the portable data terminal, the digital content image is read in response to the received data browsing request. The read digital content image is streamed to the portable data terminal.

  Therefore, even with a simple portable data terminal such as a so-called cellular phone terminal, complicated digital content data can be browsed as a digital content image. Since the digital content image is streamed and distributed in an image format that cannot be edited by the portable data terminal, unauthorized use in the portable data terminal is well prevented.

  Then, the file server apparatus 100 that has received the message returns the free text data FTD corresponding to the edit management data EMD of the received edit processing request ECR to the mobile phone terminal 300.

  Therefore, as shown in FIG. 6, the user of the mobile phone terminal 300 edits the displayed and output free text data FTD as desired, and returns it to the file server apparatus 100 together with predetermined editing management data EMD.

  In the file server device 100, the free text data FTD edited by the received editing management data EMD is specified, and the registered free text data FTD is updated.

  Furthermore, digital content data DCD and digital content image DCP are also generated corresponding to the free text data FTD, and these are updated to prevent data inconsistency.

  The file server device 100 that has completed the above-described various processes retransmits the digital content image DCP corresponding to the edited free text data FTD to the mobile phone terminal 300. For this reason, the user confirms that the digital content data DCD has been properly edited by the mobile phone terminal 300.

  In the data processing system 1000 of the present embodiment, as described above, even with a simple portable data terminal such as the so-called cellular phone terminal 300, complex digital content data DCD can be browsed as a digital content image DCP.

  In this case, since the digital content image DCP is streamed and distributed in an image format that cannot be edited by the mobile phone terminal 300, unauthorized use at the mobile phone terminal 300 is well prevented.

  However, the mobile phone terminal 300 can easily edit the free text data FTD of the digital content data DCD while preventing unauthorized use of the digital content image DCP as described above.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above embodiment, the digital content image DCP is generated and registered every time the digital content data DCD is registered.

  However, the digital content image DCP is not always stored, the digital content data DCD is read in response to the received data browsing request DPR, and the read digital content data DCD cannot be edited by the mobile phone terminal 300. It may be converted into DCP, and the converted digital content image DCP may be streamed to the mobile phone terminal 300.

  In this case, since only the digital content data DCD necessary when browsing is requested by the mobile phone terminal 300 is converted into the digital content image DCP, it is necessary to convert all of the digital content data DCD into the digital content image DCP in advance. There is no.

  Further, in the present embodiment, a general mobile phone terminal 300 is assumed as a mobile data terminal in which the digital content image DCP can be browsed and cannot be edited. However, such a portable data terminal may consist of an electronic dictionary or a portable game machine (not shown).

  Furthermore, in the present embodiment, each unit of the file server device is exemplified as being logically realized as various functions by a computer program. However, each of these units can be formed as unique hardware, or can be realized as a combination of software and hardware.

  In the above embodiment, the current mobile phone network or the Internet is assumed as a data network in which the file server device 100 and the mobile phone terminal 300 perform data communication. However, this may be an NGN (Next Generation Network) which is the next generation Internet.

  Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the present invention.
