摘要： In a system in which a plurality of network nodes (3, 4) are connected through a network (2), when a computation object (300-302) of a first network node (e.g. 3) calls a function (facility) of a computation object (400-402) of a second network node (4), the first network node obtains facility identification codes (numeral) of the object and the function from a remote reference table (310) and outputs the facility identification codes through the network (2) as a message together with the arguments of the function to the second network node (4). The second network node (4) uses the input facility identification code as a key to obtain the execution address of the facility from a local reference table (406) and executes that facility.

摘要： Information representing whether a user is included in arbitrary two of all users who may receive digital data is embedded in the digital data. Even when a plurality of users collude to alter the difference data to data of a third party other than themselves, the data representing themselves remains in the altered data, so collusion fails. An electronic watermark processing apparatus embeds watermark such that the watermark can hardly be altered even when a plurality of users collude to compare their data.

摘要： A communication system includes a control communication network (10) for transferring control data, and a data communication network (12) for transferring stream data. A communication node (14) is set on the communication system in response to a request on the stream transfer. The communication node (14) is connected to both of the above networks and transfers data via the data communication network (10) under the control based on the control data. The communication node (14) controls access by an application and transfer of stream data by referring to a transfer control table which holds the relation of connection with another control communication node (14) which transfers the common data and the corresponding relation to a control node (16) (application) associated with data transfer defined by the connecting relation.
