摘要:
An information processing apparatus includes a data processing unit which generates content to be distributed to a client; and a communication unit which sends the content generated by the data processing unit, wherein the data processing unit combines a plurality of watermarking record blocks, each of which is obtained by embedding watermarking data into a block as section data of the content, generates content in which different watermarking data sequences are set in units of distribution processing with respect to the clients, and sends the generated content to the clients through the communication unit.

A content sharing system is disclosed that can efficiently execute copyright management for limiting illegal utilization of content, and can promote the degree of freedom in utilization of content within a legal range of private utilization. In the content sharing system, a content processing apparatus on the content providing side includes a source ID addition section for adding, to the content data, a source ID for specifying a providing source of content data. Meanwhile, another content processing apparatus on the content acquiring side includes a content rendering section having a rendering permission ID list including source IDs, added to content data whose rendering is permitted, for limiting, based on the source ID added to the acquired content data and the rendering permission ID list, rendering of acquired content data rendering. The content sharing system further includes a list management section for permitting updating of the rendering permission ID list.
摘要:
A copyright management system that manages the time limits of the reproduction of a plurality of pieces of content in a batch manner. A content reproduction apparatus has a storage unit storing a reproduction permission ID list and the valid period information of each group ID and a reproduction control block for controlling the reproduction of content data attached with the group ID. The reproduction control block reads the group ID from content data and, if the read group ID is contained in the reproduction permission ID list and the current time is not in excess of the valid period of this group ID, permits the reproduction of the content data; if the read group ID is not contained in the reproduction permission ID list or the current time is in excess of the valid period of this group ID, the reproduction control block restricts the reproduction of the content data.

摘要:
A content sharing system is disclosed that can efficiently execute copyright management and can promote the degree of freedom and convenience in sharing of content within a legal range of private utilization. A group management server places a plurality of content processing apparatuses in terms of a unit of an owner into a group registration and issues a notification of a group ID of the group. A content recording apparatus adds a recorder ID thereof to production content produced thereby. Further, a content reproduction apparatus controls reproduction of content based on a recorder ID read out from content and a reproduction permission ID list. If the different processing apparatuses have the same group ID, the recorder ID can be added to the reproduction permission ID list.
摘要:
The CPU 11 of the personal computer 1 controls the CPU 32 of the adaptor 26 made of a semiconductor ID to compute a hash value of a content-managing music data base recorded in the HDD 21 and store it into the nonvolatile memory 34. When playing back a content recorded in the HDD 21, the CPU 11 computes the hash value of the music data base recorded in the HDD 21, compares it with hash values stored cumulatively in the nonvolatile memory 34, and controls the playback of the content from the HDD 21 based on the result of the comparison.
摘要:
In order to obtain coded data which does not strike viewers and listeners as being incongruous, when plural audio data are to be coded, a coding program groups the respective audio data into one audio data, codes the grouped audio data in sequence with a predetermined number of samples being treated as units, and sets delimitations corresponding to the delimitations of the plural audio data in the coded data at coding units of the coded data.
