<p>A network device is placed on the edge of a service provider's network to intercept incoming and outgoing packets from a computer within the service provider's network. On interception of such a packets, the network device uses personal information about the user of the computer stored in a database in the service provider's network, to determine if such packet should be altered, and if deeming it appropriate alters such packet before sending the packet to its destination. This allows users of the service provider's network to provide personal preferences to the service provider, which will be used by the network device to alter packets according to such preferences.</p> |
