Abstract
Content is authenticated by generating signature certificates for content that has been successfully watermark screened. When a request is received for importation of content into a secured domain, a search is made in a signature certificates cache for a signature certificate associated with that requested content. If an identified signature certificate authenticates the requested content, the content is imported into the secured domain. If no signature certificate is identified, the content is watermark screened. If the content successfully passes the watermark screening process, a new signature certificate is then added to the signature certificate cache.
