A content distribution system ( 300 ) has access control according to a predefined data access format. The system has organizations ( 32 ) for providing content data and related meta data on record carriers ( 34 ), and a rendering device ( 39 ), and applications for manipulating the content data and related meta data. An access policy for the organization is set according to the predefined data access format, and has access parameters for controlling access to resources of the rendering device and to said content data and related meta data. An organization application ( 35 ) complying with the access policy of the organization for accessing said data is executed while accessing the resources of the rendering device according to the access policy of the organization. According to the invention a user access policy is maintained that restricts, for the organization application, access to the resources of the rendering device relative to the access policy of the organization. The user access policy is adjusted based on additional trust data for selectively allowing the organization application to access the resources according to the access policy of the organization. Hence the user controls the access that applications have to resources of the rendering device. |
