发明名称 メッセージを安全に転送する方法
摘要 The present invention may be deployed in a system for broadcast of conditional access content where it is desirable to detect and take action against receiver equipment which has been used in a control word sharing activity. By requiring that receiver equipment used in the system send a message to a broadcaster of conditional access content at a precise time, the invention provides a method for the server to detect receiver equipment involved in control word sharing activity and to inhibit that receiver's ability to further access the content.
