System for registering a recordable medium, system for authenticating a recordable medium, as well as servers and client system for such systems

摘要

A system for registering a recordable medium comprises a plurality of client systems and a system server. Each client system can establish a connection to the system server through a network. The system server comprises a client database, in which details of the client systems are registered. Each client system is or can be connected to a medium player, and each client system is adapted for establishing a connection to the system server when a recordable medium is placed in the medium player. The system server generates a unique identification code, which the system server stores in the database along with the client system concerned and delivers to the client system concerned. Each client system is adapted to recording the received unique identification code through the medium player on the recordable medium. Each client system can download content files from a content server for recording on a recordable medium. Upon receipt of a download command from a client system the content server requests the unique identification code of the medium placed in the medium player from the client system. The unique identification code is delivered to the system server, and checked for authenticity by the system server. The content file is only delivered to the client system when the unique identification code is recognized by the system server.
