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.
摘要:
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:
An information storage apparatus that includes a memory unit, a first controller that reads data from the memory unit, and a second controller included in the memory unit that reads a first identification and outputs the first identification in response to an external instruction, wherein the first identification may only be read by the second controller.
摘要:
An information processing device includes: a memory having a protected area which is a data recording area in which access restriction is set; and a data processing unit that determines accessibility in response to a request for accessing the protected area from an access requesting device, wherein the data processing unit verifies a device certificate received from the access requesting device and determines accessibility to the protected area based on access control information recorded in the device certificate.
摘要:
An information processing device includes: a data processing unit that executes a process of reproducing content recorded in a medium, wherein the data processing unit acquires a token from the medium, the token being management data corresponding to content recorded in the medium, compares a server ID recorded in the acquired token with a server ID recorded in a server certificate acquired from a server from which the management data is acquired, and halts reproduction of content when the two server IDs are not identical.
