Abstract

See full text

Management of key information as described herein enables a respective service provider to distribute encrypted content to subscribers, preventing improper use of the content without authorization. For example, the service provider can distribute encrypted content for recording by a subscriber at a remote location. At or around a time of recording the encrypted content, and on behalf of the user, the service provider initiates storage of the corresponding decryption information that is needed to decrypt the recorded encrypted content. In order to play back the recorded segments of the encrypted content, the subscriber communicates with a server resource to be authenticated. Subsequent to being authenticated, the server resource distributes a copy of decryption information needed to decrypt the previously recorded segments of encrypted content to the subscriber. Accordingly, the service provider retains control of playing back content via controlled distribution of the corresponding copy of decryption information.
