A system and method is disclosed for allowing content providers to protect
against widespread copying of their content, while enabling them to give
their customers more freedom in the way they use the content. In
accordance with one embodiment, content providers identify their content
as protected by watermarking the content. Consumers use compliant devices
to access protected content. All of a user's compliant devices, or all of
a family's devices, can be organized into an authorized domain. This
authorized domain is used by content providers to create a logical
boundary in which they can allow users increased freedom to use their
content.
