Abstract
A system that distributes content access data which provides rights management data indicating a right of a user to reproduce and/or copy the distributed content. The system includes an applications device including a trusted player for receiving, reproducing and/or copying the content, and a smart card access device for accessing a smart card, such as a Subscriber Identity Module (SIM), which is uniquely associated with the user. A trusted server communicates the content access data to the smart card via a communications network by encrypting the content access data using an encryption key pre-stored on the smart card and known to the trusted server. A facility is thus provided for cost effectively distributing content and managing rights in the content using security facilities inherent in the smart card.
