Abstract
A method and system for identifying a source of a copied work that in one embodiment includes obtaining at least some portions of a reference work, collecting at least some portions of the suspect work, matching the suspect work with the reference work, wherein the matching includes temporally aligning one or more frames of the reference work and the suspect work, spatially aligning frames of the reference work and the suspect work, and detecting forensic marks in the suspect work by spatiotemporal matching with the reference work.
