An image processing apparatus enables image data to be handled easily after photography. A server apparatus patterns images and controls information in correspondence with user identifiers. A digital camera photographs a subject, obtains a pattern image and a piece of control information from the server apparatus, and judges whether a portion of the image data obtained by photography matches the obtained pattern image. If a matching portion exists, then the digital camera operates in accordance with an operation instruction included in the piece of control information. If the operation instruction is mosaic processing, then the digital camera performs mosaic processing to the matching portion. If the operation instruction is image replacement, then the digital camera replaces the matching portion with a predetermined image or performs CG processing on the matching portion. If the operation instruction is frame deletion, then the digital camera deletes the image data.

Image processing apparatus

A unit-to-unit data exchange system preventing an unfair exchange without increasing communications cost or a load on a server. A unit () exchanges data with a unit (). An exchange completion data keeping device keeps exchange completion data that is necessary for each unit (and) to reproduce the obtained data after the data exchange is completed. The exchange completion data keeping device transmits the exchange completion data obtained from the unit () to the unit () and transmits the exchange completion data obtained from the unit () to the unit () only when the unit () and the unit (1) have successfully received data of interest.

A content usage device includes (i) a license management unit that holds license information and (ii) a content output unit that uses a content in compliance with license information and outputs the content in at least one manner of a sound, video and data. The license management unit, upon receiving a request of license information from the content output unit, requests a license management unit of another content usage device to transfer the license information and acquires the license information, and passes the acquired license information to the content output unit. The content output unit uses a content in compliance with the license information passed from the license management unit.

Content usage device and network system, and license information acquisition method

To provide a content distribution system which can prevent use of content which has been temporarily stored after the valid period. A content distribution system () including a license server () which issues a license, a content server () which transmits the content, a terminal device () which controls use of the content based on the issued license. The terminal device () does not allow the use of the received encrypted content when it is judged that the encrypted content received from the content server () is not the content received in real time.

Terminal device, server device, and content distribution system

Each of at least two terminal apparatuses uses content data in accordance with license information which is generated by a content distribution system to which it subscribes. A conversion apparatus includes a working area for storing license information which is compatible with one of the terminal apparatuses, and a central processing section for converting the license information stored in the working area into license information which is compatible with the other terminal apparatus. Thus, there is provided a conversion apparatus which can convert one's own license information so as to be passable to others.

License information conversion apparatus

To reduce a frequency of recording communication management information for communication disconnection countermeasure. A digital content distribution system includes a license server () that issues a license, and a user terminal () that controls use of content based on the issued license. The license server () judges, according to the license to be issued, whether or not the communication management information for the communication disconnection countermeasure needs to be recorded, and notifies the user terminal of a result of the judgment. This enables the user terminal () to reduce the frequency of recording the communication management information.

Terminal apparatus, server apparatus, and digital content distribution system

A content distribution management system includes a plurality of content distributing devices, which each include a content storage processing unit operable to store and distribute a content, a user interface unit operable to provide viewing and information of a content for a user, a content acquisition processing unit operable to acquire a content from a content providing device, etc. and to perform purchase processing of the content, and a sending/receiving unit operable to exchange data via a communication network. The content distribution management system also includes a content distribution management device, which includes a payment management processing unit operable to perform payment processing of a content, and a copyright management processing unit operable to manage and send copyright-related information (a usage rule, key information, etc.). The content distributing devices and the content distribution management system are configured via the communication network, etc.

Content distribution management system and content distribution management method

A reception apparatus includes: a reception unit for receiving the scrambled content, the scrambled content being scrambled so that a predetermined unit of scrambled content is descrambled using a descrambling key corresponding to the predetermined unit of scrambled content, and at least one piece of storage information in which a list including all descrambling keys used for descrambling the scrambled content is embedded; storage unit for storing the received scrambled content and the storage information; list extraction unit for extracting the list from the stored storage information; descramble processing unit for extracting the predetermined unit of scrambled content from the stored scrambled content, extracting a descrambling key corresponding to the predetermined unit of scrambled content from the extracted list, and descrambling the extracted predetermined unit of scrambled content using the extracted descrambling key; and reproduction unit for reproducing the predetermined unit of descrambled content in the descrambled order.

Broadcast apparatus and reception apparatus for providing a storage service by which scrambled content is stored and descrambled using scrambling key list

A management device of a license management system acquires a usage request of a content from an SD card or a printer via a relay device, analyzes the acquired usage request, acquires usage environment information of the SD card or the printer from the relay device, analyzes the acquired usage environment information, generates license information including a usage rule corresponding to the analysis results of the usage request and the usage environment information, generates instruction information indicating how to handle the license information in the relay device based on the analysis result of the usage environment information, embeds the generated instruction information in the license information, and sends the license information to the relay device. The relay device receives the license information in which the instruction information is embedded, and transfers the received license information to the SD card or the printer according to the instruction information which is embedded in the license information with performing certain processing or without performing any processing to the license information.

License management system, license management device, relay device and terminal device

A content using system is composed of a content importing apparatus and at least one content using apparatus. The content importing apparatus includes a content ID generating unit that generates a content ID, and a content key information encryption converting unit that converts the encryption of content key information by using an encryption key ('network key') that is shared in advance on the network. The content using apparatus includes a content key information decrypting unit that decrypts the content key information, whose encryption has been converted, by using the network key, a moved content list storing unit for storing a moved content list (MCL) in which the content IDs of contents that have been written onto a storage medium are written, and a moved content list managing unit that judges whether the writing of a content is permitted or prohibited based on the MCL.
