Abstract
Anti-piracy measures for stereoscopic 3D content media displayed in dual lens projection systems are achieved by the forensic marking of each image in a stereoscopic image pair with separate component forensic marks or dots associated with each image of an image pair. In one example, the component mark used for marking one image of the pair is identical to the component forensic mark used for marking the other image of the pair. In another example, the component marks are different from each other. When superimposed over each other in proper alignment, the two component marks form a composite forensic mark. In this latter example, they each lack one or more of the forensic dots or shapes existing in the composite mark, and the component marks may or may not have one or more corresponding forensic dots or shapes in common.
