Abstract: A method and system are disclosed in a network for controlling data signalling therein. A core network includes at least a first node storing a contents parameters database. A sub-network operably interfaced with the core network includes at least a network transaction processing node. The first node and the network transaction processing node are each adapted to authenticate all users of data processing terminals connected to the network for access to the network or predetermined parts of the network and to monitor respective network signals of same for contents data encoded therein. An information exchange server is also operably interfaced with the sub-network and stores a registration and communication database having respective unique identifier(s) of each of the one or more network users recorded therein.

Abstract: A system for controlling access to copyrighted data comprises, at least: a plurality of users having computers, each computer being assigned a unique identity and each computer being configured for communicating with external units via a core network; a core network operated by a telecommunications organization; an access handler configured to communicate with the computers via the core network and a communication interface configured for routing incoming data traffic to a first database; wherein the first database includes at least one table, in which table the unique identities of the computers are associated with access rights for each one of the unique identities, and the first database is configured to communicate with a second database and a third database/server; the second database includes copyrighted data material, and the second database is further configured to communicate via the core network with the computers for transferring requested copyrighted data material.
