Description

  The present invention relates to a data processing apparatus, and more particularly to a data processing apparatus for selling digital contents as a package.

  Recently, digital content including digital data such as images and sound has been widely distributed due to the performance improvement of the network environment such as the Internet. Accordingly, content management such as copyright protection of digital content is an important issue. It has become.

  Conventionally, as a method of preventing unauthorized copying or distribution of digital content provided via a communication line or a recording medium, a generation management method (for example, limiting the number of times content is reproduced by the elapsed time of the content reproduction time) , Refer to Patent Document 1), a method for controlling output of content based on the detection result of a watermark (digital watermark) added to the content (for example, refer to Patent Document 2), locking an electronic lock on the package media, A browsing restriction method using an electronic lock that can be viewed online by using an electronic lock stored in a server computer of a vendor to enable browsing of digital contents of a package medium (for example, see Patent Document 3) has been proposed.

  Recently, DRM (Digital Rights Management) technology that restricts the distribution and reproduction of digital content has attracted attention as a technology for managing the handling of digital content and protecting copyrights and the like. There are various specific implementations of the DRM system, such as when it is built in a recording medium such as a memory card, when it is incorporated into player software for audio and video, when it is incorporated into transmission / reception and transfer software, and combinations thereof. There is. In the DRM system, a use authority corresponding to each content is given (described as right data regarding handling), and use such as reproduction of content is managed based on this right data. Accordingly, if there is no right data, the content cannot be used, and if the right to use the right data is lost, the subsequent use cannot be performed.

  As a form of selling digital content, there is a package sale in which the digital content is stored in a storage medium and sold. For example, a sale of a music CD (Compact Disc) is a typical example. A user purchases a storage medium called a CD itself is an act of purchasing music. Further, although the content itself is stored on a CD as in the case of software package sales, a separate password may be required to install the software on a personal computer.

In recent years, fraudulent acts such as illegal copying of digital content stored in storage media and distribution to third parties via the network have occurred frequently. It is necessary to take measures to manage and protect copyrights and to protect the interests of content providers.

  However, DRM does not stipulate a content distribution method or package sales, and it is difficult to take measures against fraudulent acts that hinder package sales. In addition, each of the above conventional methods is insufficient as a countermeasure against fraudulent acts that hinder package sales.

  Further, in conventional package sales, it is not possible to provide services for specific devices (for example, mobile phones) by package sales. For example, in the case of a music CD, all devices corresponding to the music CD must be automatically considered as service targets, and it is difficult to provide a service for a specific device.

  Further, in conventional package sales, it is not possible to audition contents by attaching a storage medium to a device owned by the user, and purchase after the audition. For example, in a store that sells music CDs, content can be auditioned with a test listening device installed in the store, but cannot be audited with a device (model) owned by the user. For this reason, there arises a problem that the content being auditioned is purchased without noticing that it is not suitable for the device owned by the user (music reproduction quality, image display screen size, etc.).

  As a countermeasure for this problem, it is conceivable to store content for all devices (models) in the storage medium, but it is inefficient such as the memory size limitation of the storage media and the processing for associating the content with the device, Realization is difficult.

  In addition, online sales where users download and purchase content for trial listening stored in a server via a communication line to a mobile communication device are also being performed, but wireless transmission with a small transmission capacity for large-capacity content such as music and video When downloading via a communication line or the like, it takes time for distribution, and further, redistribution processing is necessary because the line is disconnected in the middle of distribution, and the communication cost burden on the user increases.

  In addition, since content that is not encrypted (hereinafter referred to as plaintext content) or right data is stored in the storage medium in a music CD or the like, there is a problem in that the above-mentioned fraudulent acts are likely to occur.

  Also, a method is conceivable in which only encrypted content is stored in a storage medium, and right data for reproducing the encrypted content is acquired from a server via a network. However, in this case, even when only the trial listening is performed, the user first needs to perform operations such as network connection, selection of trial listening right data, and download, which is troublesome.

  The present invention has been made in view of the above point, and data processing for realizing package sales for a specific device by storing or distributing content associated with specific information for a specific device in a storage medium. An object is to provide an apparatus.

The trial content data right data encrypted by the encryption processing unit 1316 is stored in the first storage unit 1602 in the memory card 3004 via the memory card I / F unit 1306 (step S3513).

  Next, the memory card I / F unit 1306 performs a mutual authentication process between the content package server 3001 and the authentication unit 1601 in the memory card 3004, and outputs the mutual authentication result to the control unit 1301. The control unit 1301 determines success / failure of mutual authentication between the content package server 3001 and the memory card 3004 based on the mutual authentication result input from the memory card I / F unit 1306 (step S3514).

  If the control unit 1301 determines that the mutual authentication has been successful (step S3514: YES), the memory card 3004 receives the preview content title key encrypted by the encryption processing unit 1316 via the memory card I / F unit 1306. In the second storage unit 1603 (step S3515).

  Next, the control unit 1301 stores the title data title key of the trial content encrypted by the encryption processing unit 1316 in the second storage unit 1603 in the memory card 3004 via the memory card I / F unit 1306 ( Step S3516).

  Next, the key generation unit 1315 generates a content decryption key for full content and outputs it to the encryption processing unit 1316 (step S3517). The encryption processing unit 1316 reads the content body of the full content from the content storage unit 1305, encrypts it using the content decryption key for full content input from the key generation unit 1315, and outputs it to the content package unit 3112 (step S3518). .

  The content package unit 3112 generates a full content package by assigning a content ID, content-related information, and right data acquisition URL to the content body of the encrypted full content input from the encryption processing unit 1316. It outputs to the control part 1301 (step S3519).

  The control unit 1301 accumulates the full content package input from the content package unit 3112 in the first storage unit 1602 in the memory card 3004 via the memory card I / F unit 1306 (step S3520).

  Next, the right data generation unit 1314 generates full content right data and outputs it to the control unit 1301 (step S3521). The control unit 1301 transmits the full content right data input from the right data generation unit 1314 to the right data server 3002 via the right data I / F unit 3101 (step S3522), and ends this process.

  In step S3514, when the control unit 1301 determines that the mutual authentication has failed (step S3514: NO), the process ends.

  Next, processing executed in the right data server 3002 in accordance with the processing of the content package server 3001 will be described with reference to the flowchart shown in FIG.

  In FIG. 37, the right data I / F unit 3205 in the right data server 3002 receives the full content right data transmitted from the content package server 3001, and outputs it to the control unit 3201 (step S3701). The control unit 3201 accumulates the full content right data input from the right data I / F unit 3205 in the right data accumulation unit 3203 (step S3702), and ends this process.

  As a result of the above processing, the content ID 3902, the content related information 3903, and the right data acquisition URL 3904 are assigned to the content body 3901 of the encrypted preview content shown in FIG. 39 in the first storage unit 1602 in the memory card 3004. The trial content package 3910 is a transfer prohibition package 3911 packaged for transfer prohibition, and further, the entire audition content 1611 obtained by encrypting the transfer prohibition package 3911 with the title key for audition content and the encrypted content shown in FIG. The content data 1612 for the audition content and the full content 3401 obtained by encrypting the content body are stored.

  Further, the entire content data for preview content 1612 stored in the first storage unit 1602 in the memory card 3003 is encrypted with the title key for rights data as shown in FIG. An encrypted content data decryption key 1901 for the audition content, a right data ID 1902, a content ID 1903 corresponding to the audition content, a content related information 1904, and a content data right body 1910 for the audition content including the content reproduction restriction 1905 are included. .

  Note that the content reproduction restriction 1905 is set to “reproduction count restriction”, “reproduction period restriction”, etc. of the trial listening content.

  As shown in FIG. 20, the entire content data for sample content 1612 in FIG. 19 is read into the portable information terminal device 1203 and then decrypted using the title key for content data, thereby allowing the content data body for sample content 1910 to be decrypted. It becomes.

  Also, as shown in FIG. 34, the second storage unit 1603 in the memory card 3004 stores an encrypted title key 1613 for sample content and an encrypted title key 1614 for right data. As a result, a memory card 3004 is provided for distributing trial listening content at a low charge or free of charge. Further, the right data server 3002 completes the storage of full content right data for sale.

  Accordingly, since the trial contents are stored in the memory card 3004 as the transfer prohibiting package 3911, when the memory card 3004 is attached to the portable information terminal device 3003, transfer to the outside becomes impossible.

  Next, trial content reading processing from the memory card 3004 executed in the portable information terminal device 3003 will be described with reference to the flowchart shown in FIG.

  An example of the audition content package 3910 stored in the storage unit 1505 is shown in FIG. As shown in FIG. 40, a transfer prohibition flag 4001 is added to the sample content package 3910.

  Next, the decryption processing unit 1516 decrypts the right data title key 1614 of the trial listening content input from the control unit 1501 based on the unique information stored in the unique information storage unit 1503 (step S3809).

  Next, the memory card I / F unit 1506 reads the entire sample content right data 1612 (see FIG. 34) stored in the first storage unit 1602 in the memory card 3004 and decrypts the decryption processing unit 1516 in the conversion unit 1513. (Step S3810). The decryption processing unit 1516 decrypts the entire content data 1612 for trial content input from the memory card I / F unit 1506 using the decrypted right data title key 1614 and controls it as the content data body 1910 for the trial content. The data is output to the unit 1501 (step S3811).

  Next, the control unit 1501 stores the trial content right data body 1910 input from the decryption processing unit 1516 in the storage unit 1505 (step S3812). Next, the memory card I / F unit 1506 reads the full content 3401 stored in the first storage unit 1602 in the memory card 3004 and outputs it to the control unit 1501 (step S3813). The control unit 1501 stores the full content 3401 input from the memory card I / F unit 1506 in the storage unit 1505 (step S3814), and ends this process.

  In step S3801, if the control unit 1501 determines that mutual authentication has failed (step S3801: NO), the process ends.

  As a result of the above processing, in the storage unit 1505 in the portable information terminal device 3003, the trial content package 3910, the trial content right data body 1910, and the full content 3401 are stored by adding the transfer prohibition flag 4001. Become.

  Next, trial content playback processing executed in the portable information terminal device 3003 will be described with reference to the flowchart shown in FIG.

  41, the management unit 1512 in the portable information terminal device 3003 acquires the content data 1910 for trial content from the storage unit 1505 and outputs it to the right data interpretation unit 1514 (step S4101). Subsequently, the storage unit 1505 The trial listening content package 3910 is acquired from the data and output to the decryption processing unit 1516 in the conversion unit 1513 (step S4102).

  The right data interpretation unit 1514 interprets the content of the content reproduction restriction 1905 (see FIG. 20) included in the right data body 1910 for the audition content input from the management unit 1512, and determines whether the audition content can be auditioned. (Step S4103). If the right data interpretation unit 1514 determines that the sample content can be sampled (step S4103: YES), the right data interpretation unit 1514 notifies the management unit 1512 to that effect.

  When notified from the right data interpretation unit 1514 that the trial listening is possible, the management unit 1512 reproduces the content body 3901 of the trial content according to the following procedure (step S4104).

  First, the management unit 1512 outputs the sample content right data body 1910 to the decryption processing unit 1515 in the management unit 1512. The decryption processing unit 1515 uses the content body 3901 of the sample content included in the content data 1910 for the audition content input from the management unit 1512 and the content decryption key 1901 for the content for audition content included in the content data 1910 for the audition content. The decrypted content body 3901 is output to the playback unit 1508.

  Next, the playback unit 1508 performs playback processing such as D / A conversion on the audio data and the image data included in the content body 3901 of the trial listening content input from the decryption processing unit 1515, and outputs the audio signal. The audio signal is output to the audio output unit 1509, and the image signal is output to the image output unit 1510.

  Thereafter, the audio output unit 1509 outputs the audio signal input from the reproduction unit 1508 from the speaker. The image output unit 1510 displays an image on the liquid crystal panel based on the image signal input from the reproduction unit 1508.

  Next, the right data interpretation unit 1514 updates the content playback restriction (remaining playback count etc.) in the right data body 1910 for trial content according to the playback of the trial content (step S4105), and ends this processing. .

  In step S4103, if the right data interpretation unit 1514 determines that the trial content is not trial-listen (step S4103: NO), the process ends.

  Through the above processing, the user of the portable information terminal device 3003 can audition the sampled content according to the playback function (image quality and sound quality) of the portable information terminal device 3003 that he / she owns. It can be carried out.

  Next, processing for acquiring the full content content decryption key from the content / right data server 3002 executed by the portable information terminal device 3003 will be described with reference to the flowcharts shown in FIGS.

  In FIG. 42A, the control unit 1501 in the portable information terminal device 3003 acquires the trial content package 3910 from the storage unit 1505 (step S4201), and obtains the right data acquisition URL 3904 included in the trial content package 3910 (FIG. 40). Reference) is read out and output to the download unit 3311 (step S4202).

  When the right data acquisition URL 3904 is input from the control unit 1501, the download unit 3311 activates the browser, and the transmission / reception unit 3301 accesses the right data server 3002 via the mobile communication network 106 based on the right data acquisition URL 3904. Then, a request for acquiring full content right data is transmitted (step S4203).

  In FIG. 42B, when the right data server 3002 receives a request for acquisition of right data for full content by the transmission / reception unit 3206 via the mobile communication network 106 via the mobile communication network 106, the management unit 3211 Based on the full content right data stored in the right data storage unit 3203, a right data list (including the type of right data, sales conditions, price, etc.) is created (step S4211). The data is transmitted from the transmission / reception unit 3206 to the portable information terminal device 3003 (step S4212).

  Next, when the portable information terminal device 3003 receives the right data list transmitted from the right data server 3002 by the transmission / reception unit 3301 (step S4204), the download unit 3311 outputs the right data list to the reproduction unit 1508, The right data list is displayed on the image output unit 1510, and the right data of the full content is selected by the user's operation of the input unit 1504.

  When the full content right data selection result is input by the input unit 1504, the download unit 3311 transmits the right data selection information from the transmission / reception unit 3301 to the right data server 3002 (step S4205).

  Next, when the right data server 3002 receives the right data selection information transmitted from the portable information terminal device 3003 by the transmission / reception unit 3206 (step S4213), the management unit 3211 stores the right data storage based on the right data selection information. The corresponding full content right data is read from the unit 3203 and transmitted from the transmission / reception unit 3206 to the portable information terminal device 3003 (step S4214), and this process is terminated.

  Next, when the portable information terminal device 3003 receives the full content right data transmitted from the right data server 3002 by the transmission / reception unit 3301 (step S4206), the download unit 3311 stores the full content right data in the storage unit 1505. (Step S4207), and this process is terminated.

  Here, the configuration of the full content stored in the storage unit 1505 is shown in FIG. 27 as in the second embodiment. In FIG. 27, full content 2700 includes an encrypted content body 2701, a content ID 2702, content-related information 2703, and a right data acquisition URL 2704.

  Also, the configuration of the full content right data stored in the storage unit 1505 is shown in FIG. 28 as in the second embodiment. In FIG. 28, the full content right data 2800 includes a full content content decryption key 2801, a right data ID 2802, a content ID 2803, content-related information 2804, and a content reproduction restriction 2805.

  In the full content right data 2800, the content ID 2803 is included so that the full content is associated with the full content right data. Further, the content reproduction restriction 2805 includes information for restricting reproduction of full content such as “reproduction period restriction”.

  Through the above processing, the user of the portable information terminal device 3003 obtains full content right data by accessing the right data server 3002 based on the right data acquisition URL stored in the trial content after confirming the trial content. Can be stored in the portable information terminal device 3003.

  Next, an operation in the case where sample content is transferred from the portable information terminal device 3003 to another portable information terminal device will be described with reference to the flowchart shown in FIG.

  43, in the portable information terminal device 3003 that is the trial content transfer source, the content transfer determination unit 3312 reads the content main body 3901 from the storage unit 1505 when a trial content transfer instruction is input by the user's input unit 1504 operation. It is then determined whether transfer is possible (step S4301).

  As shown in FIG. 40, when the transfer prohibition flag 4001 is added to the content body 3901, transfer to another portable information terminal device is impossible.

  If the content transfer determination unit 3312 determines that transfer is not possible based on the transfer prohibition flag 4001 added to the content main body 3901 (step S4301: NO), the content transfer determination unit 3312 sends the transfer prohibition message to the image output unit 1510 via the playback unit 1508. The message is output to indicate that transfer is not possible (step S4302), and this process ends.

  Further, if the transfer prohibition flag 4001 is not added to the content body 3901, the content transfer determination unit 3312 determines that transfer is possible (step S4301: YES), and the read / write unit 3301 transfers the read content body 3901 to other destinations. Is transmitted to the portable information terminal device (step S4303), and this processing is terminated.

  As described above, in the content processing system 3000 according to the third embodiment, the unique state issuance / management server 101 issues and manages common unique information to the content package server 3001 and the portable information terminal device 3003. The content package server 3001 encrypts the trial content body by using the generated content decryption key for the trial content, and forms the trial content body 3901. The content ID 3902, the content related information 3903, and the right data acquisition URL 3904 are added to the trial content body 3901. , A transfer prohibition package 3911 in which the sample content package 3910 is encrypted, encrypted sample content right data 1612, and encrypted full content. The 3401 accumulated in the first storage unit 1602 in the memory card 3004.

  Further, the content package server 3001 stores the sample content title key 1613 and the right data title key 1614 in the second storage unit 1603 in the memory card 3004 by encrypting them with the unique information.

  As described above, the content for trial listening, the full content, and the key information corresponding to the trial content are encrypted and stored in the memory card with the specific information, and the acquisition destination information of the right data for full content corresponding to the full content is stored. By encrypting and accumulating, the audition content can be distributed at low cost or free of charge to the user of the specific device that stores the unique information.

  For this reason, the user of the portable information terminal device can check the content of the sample listening content stored in the memory card in accordance with the playback function of the own device, and proceed to the purchase procedure of full content right data. Can be easily and reliably performed by clicking the displayed URL.

  In the content processing system 3000 according to the third embodiment, the content package server 3001 encrypts and transmits the full content right data for sale to the right data server 3002, and the portable information terminal device 3003 The rights data server 3002 is accessed by the rights data acquisition URL 3904 stored in the memory card 3004 attached to the memory card I / F unit 1506, and only the encrypted full content rights data is transmitted via the mobile communication network 106. I tried to get it.

  Therefore, since the full content right data is encrypted, the full content right data can be securely distributed from the server to the portable information terminal device, and super-distribution of the full encrypted content can be realized. It is possible to increase the advertising effect in content distribution, reduce the delivery time, and reduce the communication cost burden on the user.

  In addition, since the right data for full content also includes information that restricts playback of full content, content can be protected while protecting the interests of content sellers who operate content package servers or content managers who own content rights. Playback conditions can be set as appropriate.

  In the content processing system 3000 according to the third embodiment, the portable information terminal device 3003 that has accumulated the entire sample content 1611 transfers the entire sample content 1611 to the portable information terminal device that stores the same unique information. A transfer prohibition flag 4001 is added to make transfer impossible. Therefore, unauthorized transfer of sample content can be prevented, and unauthorized use can be prevented.

  When the transfer prohibition flag 4001 is not added, the portable information terminal device as the trial content transfer destination can purchase the full content right data from the content / right data server 3002 in the same manner.

  For this reason, distribution of sample contents and distribution of full contents can be facilitated while protecting the rights of content providers, and the super distribution of contents can be expanded while protecting the interests of content sellers or content managers. Can be achieved.

  Therefore, by applying the content processing system shown in each of the first to third embodiments to content distribution, a company (carrier) that provides a mobile phone service or the like provides unique information to its mobile phone user. By publishing and storing and distributing the pre-listen content as described above in the memory card, it becomes possible to develop a unique content service.

  Also, manufacturers that sell mobile phone devices can develop their own content services. As a service form, for example, a group ID can be set between one or more portable information terminal devices as unique information, and a content service can be provided only to this group.

  In the first to third embodiments, the unique information issuance / management server receives the unique information issuance request transmitted from the content package server and the portable information terminal device. However, instead of the content package server, the content seller The requested unique information may be stored in the content package server, or the manufacturer of the portable information terminal device may request and store the received unique information in the data processing device instead of the portable information terminal device. Further, this request process may be an off-line process such as mailing a CD-ROM storing unique information in response to a written request.

  In the first to third embodiments, three examples of data to be associated with the unique information are illustrated. However, the present invention is not limited to these examples. For example, the unique information may be associated with only the right data stored in the server. . In this case, the user of the portable information terminal device storing the unique information can audition the audition content stored in the memory card without connecting to the network. In addition, full content can be reproduced simply by downloading the right data from the carrier server after trial listening, facilitating super-distribution of the content, and enhancing the advertising effect.

  In the first and second embodiments, the sample content and the full content are prepared separately, and in particular, the content of the sample content is not shown, but the form of the sample content may be as follows.

(1) Part of full content (for example, only the first 30 seconds of music, only rust part, 5 pages of document data, up to 3 pages of JAVA (registered trademark) game)
(2) A collection of part of the full content (for example, a movie digest version)
(3) Reduced version of full content (for example, still image, reduced image size of moving image, etc.)
(4) Low quality version of full content (for example, low bit rate version of music)
By making the trial listening contents as shown in (1) to (4), the portable information terminal device can make the trial listening even if it does not support the restriction by the right data (restriction of the number of times of reproduction, etc.). Become.

  Further, the restriction content set in the right data may be as follows.

(1) Limit the number of playbacks (eg, up to 3 times)
(2) Reproduction period restriction (for example, what month and day, how many days from the first reproduction)
(3) Total playback time limit (for example, total playback time is 10 minutes, etc.)
(4) Reproducible part restriction (for example, only for the first 30 seconds of music, only rust part, 5 pages of document data, up to 3 pages of JAVA (registered trademark) game)
In the right data, by setting the restriction contents such as (1) to (4), it is possible to restrict the audition more finely.

(5) Rather than describing specific restrictions, the audition method is automatically selected according to the type of content (for example, the number of times that the music can be played is shortened (only for the first 30 seconds of the music) and the number of times is limited. None, games have a limited number of times)
In this case, the right data creation side does not need to set detailed restrictions, and the portable information terminal device automatically sets the reproduction restrictions according to the type of content. The burden on the side can be reduced.

  In the second and third embodiments, the purchase timing of the full content or the full content right data is after the trial listening of the trial listening content, but the following timing may be used.

(1) There is no right data corresponding to the start of playback of full content or sample content (2) Rights data corresponding to the start of playback of full content or sample content cannot be used (for example, the remaining number of playbacks is 0, the remaining playback is Time is 0 seconds, expired, etc.)
(3) The right data corresponding to the end of playback of full content or trial content is almost unusable (for example, the remaining number of playbacks is less than a certain number, the remaining playback time is less than a certain time, the time until expiration is less than a certain time, etc.)
(4) Every time sample content is played back or limited rights data is used By prompting the user to purchase at the appropriate timing as described above, the user's purchase process can be simplified.

(5) The user designates full content or trial content and requests purchase. In this case, purchase processing can be performed at an arbitrary timing requested by the user.

  In addition, after the purchase of the full content and the right data, when the sample content or the restricted right data remains in the portable information terminal device, the following processing may be performed.

(1) Automatic deletion of preview content and restricted rights data after the purchase process is completed. (2) The portable information terminal device automatically displays full content, not restricted content data, and unlimited rights data instead of trial content when playing the content. (3) When reproducing the content, the portable information terminal device automatically gives priority to the full content, not the restricted right data, but not the restricted right data, and allows the user to select it.

  By performing the processing after the purchase processing as described above, it is possible to suppress the use of the trial listening content and the limited right data whose value is reduced after the purchase processing, and to simplify the content reproduction processing by the user.

  Moreover, in the said Embodiment 2, 3, although the case where the content after reading in a portable information terminal device was made transferable to another portable information terminal device, and the case where transfer was impossible were shown, the following contents are shown. The transfer control may be performed.

(1) Content transfer (content type) and whether the data is transferable / not transferable based on whether the data is right data (2) Package type, file extension, etc. Judgment of transferability / non-transferability of content according to file name, folder in which data was stored, etc. By performing the transfer control as described above, specified according to the data read restriction associated with the specific information from the storage medium It is possible to provide services only to other terminals. In addition, the advertisement effect can be enhanced by making it possible to transfer the audition content and restricted right data.

(3) At the time of content transfer by e-mail, it is determined whether it is a terminal of a specific carrier with an e-mail address, and it is determined whether or not the content can be transferred. When the data read from the storage medium is associated with a specific carrier ID, Carrier-specific services can be implemented while sharing data between terminals of the carrier.

  In the second and third embodiments, the content / right data server and the right data server are used separately from the content package server, but these may be integrated.

  The present invention realizes package sales for a specific device by storing or distributing content associated with specific information for a specific device in a storage medium, and electronic devices such as a portable information terminal and a mobile phone device In addition, it is useful for a data processing system, a data processing apparatus, or the like that processes data including right data related to the handling of digital content in a storage medium such as a memory card.
