Abstract
There is disclosed a content protection method and apparatus. The content protection method and apparatus further improves such related schemes by facilitating spatial as well as temporal management of content. This is achieved by storing encrypted content and a corresponding decryption key and destroying the decryption key when suitable. In order to further facilitate the content protection, the decryption key may be received periodically, which allows for a large number of people to connect to the network at different times.
