A system for controlling access to copyright protected data stored on a second database on a network, at least comprising: a) a plurality of users having computers (10, 11, 12, 13, 14), each computer being assigned a unique identity and each computer being configured for communication with external units via a core network, b) the core network operated by a the- network access provider, c) an access handler provided at least with a first communication interface with the core network and configured to communicate with the computers (10, 11, 12, 13, 14) via the core network and a second communication interface configured for routing incoming data traffic to a first database, d) the first database comprising at least one first table, in which first table unique identities for the computers (10, 11, 12, 13, 14) are associated with access rights for each one of the unique identities and wherein the at least one first table comprises a mapping between the unique identities of the computers (10, 11, 12, 13, 14) and the copyright protected data stored in the second database on the network to which access shall be grantable, and the first database being provided with a third communication interface configured to communicate with at least the second database, and e) the second database comprising copyright protected data, the second database being further provided with a fourth communication interface with the core network configured to transfer copyright protected data from the second database via the core network to those computers (10, 11, 12, 13, 14) which have been granted access in the first database to the copyright protected data; wherein the system further includes means allowing the network access provider to prevent access to particular addresses (7, 8), databases (7, 8), or data (7,8) for computers trying to gain access to the particular addresses (7, 8), databases (7, 8) or data (7,8). a) a plurality of users having computers (10, 11, 12, 13, 14), each computer being assigned a unique identity and each computer being configured for communication with external units via a core network, b) the core network operated by a the- network access provider, c) an access handler provided at least with a first communication interface with the core network and configured to communicate with the computers (10, 11, 12, 13, 14) via the core network and a second communication interface configured for routing incoming data traffic to a first database, d) the first database comprising at least one first table, in which first table unique identities for the computers (10, 11, 12, 13, 14) are associated with access rights for each one of the unique identities and wherein the at least one first table comprises a mapping between the unique identities of the computers (10, 11, 12, 13, 14) and the copyright protected data stored in the second database on the network to which access shall be grantable, and the first database being provided with a third communication interface configured to communicate with at least the second database, and e) the second database comprising copyright protected data, the second database being further provided with a fourth communication interface with the core network configured to transfer copyright protected data from the second database via the core network to those computers (10, 11, 12, 13, 14) which have been granted access in the first database to the copyright protected data; wherein the system further includes means allowing the network access provider to prevent access to particular addresses (7, 8), databases (7, 8), or data (7,8) for computers trying to gain access to the particular addresses (7, 8), databases (7, 8) or data (7,8).
