摘要:
A system and method for marking, coding and tracking a film print in an efficient, adaptive and customized manner for providing unique and robust identification of each individual film print and for facilitating accurate tracking of the origin of a pirated copy is described herein. A film print to be marked is calibrated and provided in computer-readable form for input to a prescreening device. The calibrated film print is reviewed and ideal locations on each frame of the film print are chosen for applying a mark. A unique coding scheme is generated for each desired print. If a pirate copy is found, all marks are located and a matching serial number (e.g., coding scheme) is determined for the pirated copy based on marks found in the pirate copy when compared to a database storing film print mark information generated during the marking and coding process.
