US Patent 7415721 Separate authentication processes to secure content

A method includes associating a first authentication process with content, the first authentication process to protect the content from access by an unauthorized user. A second authentication process is also associated with the content, the second authentication process to protect the content from access by an unauthorized device. The first authentication process and the second authentication process are separate and distinct authentication processes. This enables an authorized user to access the content on an authorized device and prevents the authorized user from accessing the content on the unauthorized device.
