Abstract
Client control may be provided. First, content may be encrypted using an actual key. Then an identifier corresponding to a client device may be received and a transformation may be performed on the actual key and the identifier to produce a transmitted key. The transmitted key and the encrypted content may then be sent to the client device where it may be received. The client device may then receive the identifier corresponding to the client device and perform a reverse transformation on the transmitted key using the identifier to produce the actual key. The content may then be decrypted with the actual key.
