ABSTRACT:
A method for uniquely identifying a copy of a motion picture disposed on a medium. A first sequence and a second sequence of the motion picture each can be selectively marked with an identifier mark to collectively define a uniquely identifiable marking pattern. A third sequence of the motion picture can be selectively marked with an error correction mark correlating to the uniquely identifiable marking pattern. The uniquely identifiable marking pattern is determinable absent at least one of the identifier marks by processing the error correction mark and remaining ones of the identifier marks. The error correction mark can be determined from values correlating the identifier marks.
