Abstract
Techniques are described for associating identifiers (e.g., digital watermarks) with video content in a way that enables identification of the source of pirated content with specificity as granular as an individual user account. A compositors operating in the DRM trust zone of a client device introduces the identifier by compositing overlay information with decoded video frames. The identifier may then be recovered by comparing target content to the source content to extract the overlay information.
