Abstract
The system for content traceability using segmented watermark encoding disclosed herein provides a method for applying a distinct identifier to digital content, such that the a copy of the digital content can be traced to the original recipient of the content. The method comprises generating multiple copies of the digital content and applying distinct digital watermarks to each copy. The method further comprises interleaving segments of each digitally watermarked copy in a pattern that represents a unique identifier, to create a distinctly identifiable copy of the digital content. The identifier can be extracted from a distinctly identified copy of the digital content by examining the watermark applied to each segment that comprises the digital content.
