Abstract: Watermarking of a content stream is accomplished in a session-based manner to provide watermarking based on a uniquely generated manifest that will result in a stream that allows for unique identification of information. The manifest specifies a sequence of watermarks for successive segments of a content stream designated for a specific receiver. The system and method leverages existing content distribution infrastructure and has many of the benefits of conventional head-end watermarking, allows unique identification of small segments of the data stream and reduces content distribution network storage requirements. Groups of nodes can be provided with unique watermark patterns and detection and watermark pattern reconfiguration can be accomplished in an iterative manner to find a specific node without the need to create unique watermark patterns for each node.
