Abstract
A machine-implementable method for uniquely watermarking a content object according to end user identity includes transcoding an original content object to a format that is compatible with end user systems, and storing the transcoded content object where it is accessible by one or more points of presence (POPs) of a content delivery network. One of the POPs receives identifying information associated with a specific one of the end user systems. A digital watermark engine adds uncorrected digital watermark information correlating to the end user system, to the content object, to form a uniquely watermarked content object. The uncorrected digital watermark information is correctable by error correction capability of the specific end user system to deliver a version of the content object that is indistinguishable by a human from the original content object. The method further includes transmitting the uniquely watermarked content object to the specific end user system.
