Abstract

The invention relates to a method and system for watermarking in a content providing system having multiple parties. A first party system selects a first party watermark by selecting a watermarked copy of at least one first content element of the content elements. A second party system selects a second party watermark by selecting a watermarked copy of at least one second content element, different from the at least one first content element, of the content elements. Watermarked content is delivered to an end user device, the watermarked content containing the watermarked copy for the first content element selected by the first party system and the watermarked copy for the second content element selected by the second party system such that the watermarked content contains the first party watermark and the second party watermark.
