摘要： A method of information processing in a server/client system including a server for storing content and a client for receiving from the server and storing copy content of the content stored in the server. The method includes the steps of: the server generating at least either a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is permitted out of the copy content stored in the client or a content-ID list storing content-IDs corresponding to content for which use-expiration-date updating is not permitted, transmitting the content-ID list to the client; and the client selectively performing update processing of use-expiration date out of the copy content stored in that client or invalidation processing of the copy content stored in that client based on the content-ID list received from the server.

摘要： In a configuration allowing a client to be designated as a proxy server, the proxy server to register an external client to serve as a member client and the member to utilize a content, a content-utilization management server designates a client as a proxy server whereas the proxy server checks an external client connected to an external network and registers the external client to serve as a member client having a right to utilize a content managed by the content-utilization management server. Then, the proxy server gives a license to the external client as a right to utilize such a content. Thus, the external client not connected to a local network of the content-utilization management server is also capable of utilizing the content based on the license.

摘要： A content transfer system includes a source device transmitting content and a sink device receiving the content. The sink incrementally validates portions of data of the content received from the source device. The source device incrementally invalidates the portions of the data of the content transmitted therefrom in order to move the content from the source device to the sink device.

摘要： An information processing apparatus operating as a content use management server is disclosed. The apparatus includes a storage unit for storing a license as information for granting rights to use content and content attribute information, and a data processing unit for carrying out a content state shifting process in which to shift content usable states. The content usable states are formed by a bound state and a discrete state. The bound state refers to the state in which the content is allowed to be used by any of member clients on a local network of which the content use management server is a part. The discrete state refers to the state in which the content is allowed to be used only by a member client retaining the license for granting rights to use the content. The data processing unit updates descriptive information on the license and the content attribute information stored in the storage unit in order to shift the two content states.

摘要： In view of the connection of a home network to an external network via a home router, using a mechanism that access from the same network is provided with a source MAC address whereas a source address field is rewritten to a MAC address of the router in the case of external access via the router, whether or not access is made from the home network is automatically identified by comparing a MAC address of a device on the other side of communication with a MAC address of the home router. It is capable of suitably managing so that a client terminal uses the contents legitimately acquired on a home server within the scope of private use allowed by the copyright law.

摘要： In view of the fact that devices connected on a home network are located in home, that is, at close range and therefore a user can physically access the devices within a relatively short period of time, identifying whether or not a home server for distributing the contents and a client terminal using the contents are connected to the same home network based on whether or not they can share access to the same physical medium within a short period of time. The authenticity of devices connected on a home network connected to an external network via a router is authenticated.
