ABSTRACT:
Method and apparatus for uniquely identifying a copy of a motion picture disposed on a media. The method includes the steps of selecting two or more motion picture scenes. Each of the motion picture scenes is an identifiable portion of the motion picture distinct from every other portion of the motion picture. Once the scenes have been identified, two or more sequences can be defined within each of the motion picture scenes such that each sequence includes two or more frames. For example, the motion picture can have three scenes, each divided into twenty eight sequences, with each of the sequences containing 12 frames. Once the scenes and sequences have been selected, at least one of the sequences from each scene is marked to define a uniquely identifiable marking pattern on the media.
