Relating to Consumption of Content

Abstract

A method and apparatus for consumption of content ( 1 ) is described in which a licensor is able to exercise control over consumption based on a personal identity in the form of a set of binding attributes ( 15 ). The control may be exercised for a number of consuming terminals ( 19 ) including rendering machines such as portable video and audio players.

       54 . A method of distributing encrypted content to a rendering machine comprising: 
 delivering encrypted content and a license relating thereto to a rendering machine, the license containing binding attributes corresponding to a user identity; and    requesting authentication of the attributes by a personal trusted device.    
   
   
       55 . A method as claimed in  claim 54 , comprising: storing securely a license decryption key on the rendering machine.  
   
   
       56 . A method as claimed in  claim 55 , wherein: 
 the license decryption key is in a protected processing environment and is a private key with a corresponding public key being used to encrypt the license.    
   
   
       57 . A method as claimed in  claim 54 , 
 wherein: the binding attributes comprise a public key certificate of a user.
