Abstract
A system renders content by detecting a command to render content. The system determines if a policy associated with the content indicates that a rendition of the content requires a content code. The system then communicates with a policy server to allow production of the content code for inclusion within the rendition of the content. The content code is decipherable to identify historical characteristics of the rendition of the content. The system produces a rendition of the content that includes the content code.
